100% Soft Speaker Sweater

In which I once again try to solve all of my problems with knitting. This project changed a lot as it progressed; I learned a whole lot and think I made some big steps forward in researching soft circuits for my own practice. the goal of this piece was to make not a garment with electronics IN it, but a garment that IS the electronic, i.e. the full integration of wearable&electronic. It’s also supposed to be very snuggly and cozy, so I tried to maximize soft&fluffiness, and was very successful in that.

Above right, the controller is hidden under the folded turtleneck collar and the buttons to toggle the 2 audio files on and off are easily pressed with the right hand.

You can see the amplifier under the speaker in the above left pic; components are connected with conductive thread sewn into the knit fabric using duplicate stitch. The chenille texture allows the thread to be pulled tight against the core thread of the yarn. The yarn is very bulky as well, and this combined with the “shag carpet” texture hides thread and wires.

9V battery slips inside the front pants pocket; I drafted some designs with a little knit pocket for the power source in the sweater itself, but that ruined the fit and line of the garment. What I like about this solution is that the power source can be switched on separately from the audio toggle; so the circuit can be all ready to go and the wearer just needs to press the button at the collar when they feel like surrounding themselves&their cuddle buddy with some ambient fuzz noises.

Materials

simage4

CPX controller
Mono audio amp (1.4W 8ohm)
Conductive thread
26 AWG copper magnet wire
Royal Velvet Yarn by Loops and Threads
Knitting needles
Battery pack with switch (I tested with a 9V pack and a 4 AA pack before I decided on the 9V)
Neodymium magnets (I tested 1/2″ and 1/4″ before deciding to just sew both into each speak for max range)
My roommate (age 28)

Ideation & Planning:

I wanted to make an “intuitive makeout soundtrack sweater.” My early ideation was for a cozy sweater with hidden small speakers sewn into it, that each played an audio track mapped to a pin of the CPX controller. The plan was to break the circuit for each speaker with a contact sensor that would connect when someone placed  a hand (i.e. hugging/cuddling the wearer and placing pressure on the sensor) on the location of that speaker.

sfirstssecond

I am left-handed, so I consulted with a few right-handed people to choose the locations of my audio output areas and settled on these areas, from which I chose four for the final piece:

In researching the audio capabilities of the CPX controller, I came to the conclusion that there were not enough pins or memory in the controller for my original plan to be feasible. The controller can also only send audio to powered speakers, and so wiring a power source for all my tiny store-bought speakers would use up more pins than were available (I still have the little speakers from creatron though, and they are still really fun to add to other stuff).

ring1ringcommandringcircuit

circuitthoughtsbluerandom

This led me to instead begin designing a sweater with speakers integrated into the fabric itself. The locations of the audio outputs, power source, and controller remained the same as in my original proposal. The path of the conductive thread I sewed throughout the knit fabric of the sweater to connect all the circuits stayed the same as well.

Process:

Obviously the first step was to knit a sweater, so here it is with my needles still stuck in it before it was finished (there’s no pattern to cite, I just measure the person and knit from the top down):

And here it is all grown up with finished, constructed speakers and controller sewn in.

hiddeninsidefrontinsidebackimage3

To create the speakers, I knitted coils (1 for each speaker) from copper wire. These function as the front of a speaker; to hold the magnet to the back, I knitted little pouches out of conductive steel thread. The magnet sticks to this square of fabric, and the outer edges are sewn to the copper swatch with more conductive thread.

vmcoilsimage0image3image4

At this point I set up some little test circuits before sewing in the amplifiers and controller; I had made a separate fabric swatch and speaker coil for this.

vm-testwiderotates

Here I found out that 9V was necessary to power all my soft speakers, and that an mp3 in stereo that was above a certain file size could not be played through a mono amplifier, or sent to a single speaker, even if I clipped the stereo audio jack so that left, right, and ground ran through a single wire. I also learned that this is the wrong way to clip it, the clip should go vertically and contact all 3 rings:

Reflections & Next Steps:

Part of the charm of the ambient-noise-cuddle-sweater is that the audio was crappy; but for next time, larger, stronger magnets will be a must. The area of the speaker coil that vibrates depends on the range of the magnet, which depends on its strength. The next size up from the largest magnet I used is almost 20x more expensive, so I may research other aspects of speaker construction that I could alter in my design to increase volume.

Another option could be to add volume controllers or a different type of amplifier into the garment, but this would affect the softness of the circuit, which is my priority in all my pieces for this class.

Although the final piece ended up just having audio turned on/off from the CPX, I kept the speaker placements from my original sensor-triggered circuit so I can develop this idea further. The major obstacle to my original vision was that there just aren’t enough pins! In the future, I would redesign the sweater to omit the CPX completely; since the controller can only play audio through powered speakers, my thinking is that once I have to build soft speakers AND their power source, I might as well make that the focus of the wearable. Doing this also cuts down on some wires/connectors, which leaves room to bring back the pressure sensors I originally wanted.

If I did this project again, I would basically take the ipod test circuit from my process above and sew that into the sweater, but increase the voltage of the power source and get stronger magnets as well as amplifiers.

This project ended up being more of a prototype, but I really enjoyed learning about and researching the construction of fabric speakers (of all types), as well as of speakers in general. I plan to continue working on pieces similar to this moving forward.

Distance Detection Mask

Concept

This work is a mask combined by CPX and HC-SR04 ultrasonic distance detector. This mask’s shape is inspired by the doctor’s kit invented by Charles de Lorme, a French doctor in the century, to prevent the transmission of the Black Death. The shape of the mask looks like a bird’s beak. At the time of the Black Death epidemic, doctors would fill the brim with spices and herbs and sprinkle perfume outside to avoid the disease’s spread. I will install a distance detector on this. When two people are too close to the distance sensor will sense the distance is too tight and feed the data to CPX then CPX will respond.


Objective

Because of the current Covid-19 pandemic, everyone has started wearing masks to avoid contracting Covid-19 and spreading it to each other. So I wanted to make a mask with protective properties and at the same time remind people to keep a safe social distance to ensure their safety better, and I also wanted it to serve as some warning. At first, my idea was to install a distance detection device and CPX directly on the ordinary mask, but then the warning effect would be weakened. So I decided to change the shape of the mask to turn it into a beak mask look. The beak mask shape has creepy, so it often appears in some horror games. I hope this mask so that in a particular protective, at the same time his appearance can also play a specific role in warning to remind people that only with an excellent mask to prevent the epidemic to avoid being infected actively. Covid-19 brought people harm will pass as soon as possible, after all, every day with such a mask to bring people only uncomfortable and unattractive. The distance detector will be installed on the outside of the mask. When the distance between two people is lower than the safe distance, CPX will be activated to send sound and light to remind people to maintain a good social distance.

Reflections & Next Steps 

At first, I wanted to build the mask directly from leather. Still, I realized that there was no way to make it at my current level and with no experience producing leather goods, so I chose to print off a paper model of the mask and then glue leather on the top to make it look like a natural plague doctor mask. HC-SR04 is a distance detector worth exploring, and it can be combined with many things to produce a different effect. But I found making it that it detects a wide range of angles, and it is also more sensitive and can easily detect things at a set distance. The most obvious disadvantage of this surface is that this distance detector will react as soon as it detects something within that distance. My design concept only wants it to react when it detects people too close to each other. So the next step, I will study what equipment can only detect people (infrared) and then improve this mask. Then I will give up the foundation of paper modeling to learn about leather manufacturing and then use the full leather for mask production.

Open Project – John Xu

Concept

In this Wearable Electronics final open project. I want to make a piece that is closely related to my major, Jewelry. A brooch design had stayed in my mind since the moment I took this course. To keep the design simpler, I chose a flower pattern to incorporate with one of my previous expressive wearable assignments, the Pleasant Shaker. This brooch will be worn on my working apron as the medal shows the completion of this Wearable Electronic Course, my last elective course in OCAD.

Objective

Start from high school, my favourite course is called metal design, a very simple course teaches basic metalworking skills, such as fabricating, soldering, and casting, etc… When it comes to picking a post-graduation institute, I went straight to OCAD because its MAAD program had a branch call Jewelry. The very first class in OCAD was the Intro to Jewelry course. This course teaches the same staff just like what I learned in high school. So that I put more attention around the classroom. The most attractive thing in the class is the brooch pins where our instructors hang on their apron. The brooches are not very shiny but hang like medals from their career. So that I want to make something showing the graduation of this course.

Reflection and Next step

For the power cord, I tried to remove the protective rubber layer on the type-c cord. But it makes the connection weaker to work with. Unfortunately, the power cord breaks when I tried to insert it into the case. In the future, I will try to show some of the electronics rather than put them all in the case. If the design in the proper way some of the electronic units can be more attractive than the outer case. To simplify the design in the future work will be considered more like only make a frame to hold the electronic units like gemstones. Even though the CPX is a powerful unit to work with, I will still try to incorporate more other electronic units in the future. After working through this course, I had learned a lot about how the electronic unit can be incorporated in the form of jewelry. I started building the basic knowledge around wearable electronics and will keep developing it with jewelry in the future.

Open Project : The SummerTime Purse

DIGF 2016 Open Project- Khushi Jetley : The Summertime Purse

Concept

Summer is a fun time of the year. A day out at the beach or the amusement park can be a lot of fun. However dehydration, heat exhaustion and sunburns are few of many problems that individuals can face during the hot summer days. The summertime purse not only acts as a vessel to carry your essentials whilst you enjoy but also will act as a reminder to take care of yourself.

Objective

Summertime Purse will act as a means of self care during a busy day. Oftentimes when we are out with other people, amid having fun, we tend to forget to take care of ourselves. Hence, this bag will act as a reminder of taking a sip of water, or putting on sunscreen, or trying to cool down.

The bag is equipped with a temperature sensor, that makes the flowers light up if the temperature is more than 10 degrees Celsuis. When the individuals open the bag the lights on the butterflies and the flowers start blinking, reminding the uses to take a break and put their needs first.

Process

Reflections & Next Steps

This project was a really good learning experience. I had no experience with sewing, so this was my first big sewing project. It was very informative as well as frustrating at times.

My project was different from my proposal as I proposed to create a responsive scheme of LEDs that was dependent on the analog input from the sensor. However, the final project was a bit simpler, as it only took a singular output to create the behaviors of the LEDs. In future, I would refine the wiring of the circuit, to make the product more efficient. I would also like to use a better temperature sensor, to make the product more interactive.  I intend to make the bag functional all year round, with more room for the analog input. I would also like to create timed-based specific patches that reminds the user for specific things. With more practice I would also like to make the bag more polished and well-built.

Assignment 4: Open Proposal – Imra Ali (3187224)

Concept

I created a hydration clip that supports the wearer’s water-drinking journey. The portable device has a clip at the back that can be placed onto any article of clothing. The device has 2 buttons and 10 lights to support the interaction of water consumption. Button 1 (A) has a water drop icon on it and the wearer presses the button after they drink a glass of water. As there are 10 lights, the daily goal is to complete the ring. Once the daily goal has been achieved, the device turns on the celebration lights and sound. Button 2 (B) has a timer icon on it and when the wearer presses the button, their activating a 1-hour silent alarm. Once the timer is completed, a sound is played to remind the wearer to drink water. The timer is only activated when the wearer presses the button and wearers do not need to wait for it in order to drink water.


Objective

Consuming water is an essential part of the human body. This liquid helps regulate our organs, tissues, temperature, emotions, and performance. When looking at stats, humans around the world are not drinking enough water. Therefore, I decided to blend these two elements and create a hydration clip. Companies have tried many innovative ways to promote daily hydration such as building apps or creating smart bottles but unfortunately, people are still not motivated. Reminders from hydration apps get lost with other notifications and smart bottles are costly. Water bottles cannot be attached to a person 24/7 but this hydration clip can. My hydration clip is an effective solution since your daily counter is constantly on display with a built-in timer to remind you to drink. The satisfaction and urge to complete the ring provide an addictive rush. Wearers want to complete their rings and get rewarded with celebration lights and sound. This device is an effective way to support people’s water drinking journey and creating a healthy lifestyle.   


Process

With the concept in mind, I began by creating a diagram to understand the input and output of each button. Next, I selected the colours for lights for each state and design the sleeve for the CPX.

diagram water-counter daily-goal-celebration

With the above documentation fixed, I was ready to move on to the coding process. Below is a screen of the code used on the hydration clip.

makecode

Once the coding process was complete, I moved on to the construction process of the sleeve. The material I used to cover the CPX was felt because it was soft but durable. I used claw clips since they have big mouths and can easily attach to any clothing. For the diffusion material, I used printing paper and wax paper. The construction was long and tedious because the lights had to align with the holes and the covers needed to be sewed on correctly. 

Below are close-up pictures of the sleeve and the implementation with lights.

Reflections & Next Steps

Overall, I enjoyed creating the hydration clip. Reflecting upon my exploration journals and assignments, they all were building blocks that helped to create this concept. I learned that coding requires a lot of experimentation and that I will not get it on the first try. 

The construction process was my favourite because it requires great detail and precision. I went through multiple trial and error sessions before settling on this design. By doing this, I built confidence in creating the final sleeve. The sewing process was quite difficult because I had to make sure all the lights aligned with the holes that were created. 

In the end, I was happy with the creation and how much I have grown by taking this course. My next step for this project is to see if motion can be used to detect the wearer’s movement of drinking water. Also, I would look into batteries that would help to make the device portable.

Open Project

The Piano Wrist 

Concept

This project’s concept is revolved around the idea of creating music wherever someone may be. They could create simple chords and beats with the help of this wearable. This wearable could also be used as a buzzer or as a tool for games played with one’s family.


Objective

I have always had times when I am out with my family and I get an idea for a potential artwork or project that I could create in the future which most of the time I resign to typing out in the notes app on my phone. With this understanding of how I felt about getting one’s creativity flowing and unable to start that project when you get the idea I came up with a tool to hopefully help musicians and anyone who writes music to try out their ideas if they get them in locations where an instrument is not available. With the piano wrist, my objective is to create a tool that is easy to use, comfortable to wear and is easily accessible whenever someone is struck with inspiration.


Interactions

Project Interaction: The original idea I had was to use digital switches using a glove, each finger would control a different note played when touched with conductive fabric, after some research and thorough understanding of concepts learned in class it was decided to use capacitive touch sensors to activate the sound and lights, this is so everything could be kept in one place and it would be easy for the user to make music with this product.

Input: Capacitive touch sensors, Button B and the onboard Switch.

Output: Sound and Light.

Designs

design

After some contemplation, I went with design 1 for my final product, and in order to make it comfortable, I decided to have the “watch” face removable by a button attached to the wristband.

Creation

I began creating my wearable by testing the capacitive touch sensors on the CPX with a basic set up of my code.

testing-capacitive-touch-sensors

Used the embroidery hoop to stretch fabric and make it easier to sew the CPX to the cotton and conductive thread paths. I had attached the CPX to the by sewing only through the pins that would not be used for the capacitive touch sensors.  I had to use every pin for the capacitive touch sensors and didn’t want to risk the circuit stop working if I had sewn it through.

After sewing the first line of conductive thread I decided to use the conductive thread instead of conductive fabric as the actual “buttons” as adding the conductive fabric circles wouldn’t have looked too nice against the blue of the fabric and I wanted to sew in the letters beside the sensors.

Reflection & Next Step

Overall I am very happy with how my Open Project turned out as it does what I planned and I really enjoyed creating my model. If I were to remake this project then I would probably make the watch head smaller or try the other design as it would make the end product less bulky. A part of this project that I’m really happy with is the code. Programming the CPX to have a more exciting output than just the sound was something I enjoyed.

Open Project- Lily Cen(3184946)

Concept:

   What I make is a glove that can emit light and sound. I put CPX on the wrist of the glove so that it won’t affect my normal hand movements (such as holding something). There are two unconnected spans of conductive lines at the bottom of the glove. When the two parts are disconnected, CPX will emit light. When I put on my bracelet, the two spans of conductive lines will be linked, and the light goes out completely until the circuit is disconnected again. Secondly, I also added an audio output. When the D7 button on CPX is turned on, the music will ring out. Because the bracelet will be tightly worn on the hand, there is no need to worry about the light trigger will be particularly sensitive. The connection between the two circuits will not be easily disconnected.

Objective:

  My idea of making this pair of night light gloves is very simple. It was completely stimulated by the long winter in Canada. I used to live in Mississauga, and at night the lights on the street were dim. It was even a power failure that occurred one winter in the whole street due to a blizzard. I can actually turn on the flashlight in my mobile phone, but it’s really cold to hold my mobile phone in my hand all the time (even if I take gloves, but to unlock my mobile phone, I still have to take off my gloves). Secondly, my mobile phone is often frozen to the point of turning it off. So I want to make a glove that can be used for lighting, simultaneously keeping my hands warm. Besides, there is also a very important reason, that is, I am deeply influenced by some movies and animation. I think that emitting lighting from hands is a very cool thing, and having a sense of future technology. Of course, I always try to add more functions to my product. The purpose of adding audio is to improve the safety of people walking alone at night. When I write the code, I try to make the music longer and the volume higher. Once someone is in danger, turn on the switch immediately. The sudden sound may make the other person shake his mind. You can take the opportunity to escape. If you are lucky, you can also attract other people to help you. Of course, this is only a rare case. The trigger of “lighting” and “alarm” functions are two completely different switches, so don’t worry that you will walk on the street and suddenly CPX will give an alarm to scare other people.

I forgot to take pictures, so I drew a step diagram.

  1. First, sew CPX on the gloves with black cotton thread
  2. Connect pin A1 and two resistors with conductive thread and sew a row of lines on the bottom of the glove. Then start at Pin 3.3V and sew to the bottom, leaving a row of lines.
  3. Finally, cover the Cpx and resistor with black stockings, leaving the bottom two spans of lines exposed.

Reflections & Next Steps

Although “lighting” and “alarm” two functions have been realized in my final work, they can still be improved in some ways. First of all, about the “lighting” function, I set the disconnection circuit to be “on” and the connection circuit to be “off”. However, this seems to be contrary to everyone’s habit. To be honest, I tried to set “disconnect the circuit = turn off the light”, and “connect the circuit = turn on the light”. However, there is a big problem: once the circuit is connected, the light will remain activated. Even if the circuit is disconnected, the light will only flash and will not be completely turned off. I think the most important character of “flashlight” is that it must be able to be completely controlled by people with its “on/off” status, so I finally chose the setting of “disconnection = light on, connection = light off” to ensure practicality. The second problem is that I choose to use black stockings to cover the exposed CPX, but it greatly reduces the brightness of the light. To improve my design, I think I should choose another material with strong penetration to cover CPX. After all, “lighting” is the core concept of my design.

Try a medium that softens the light–Water

In my first journal post, I want to share the code I learned in the Adafruit tutorial. The name of the tutorial is “night light”, which can make all the light bulbs on the CPX emit strong light. In my previous works, I think the light on the CPX is too bright for human eyes, so in my future works, I prefer to let the light shine through some media to soften the light. The medium I want to try first is water. I would like to explore how different colours of light refracting through the water. I chose six colours in this experiment: red, green, blue, purple, lavender, and light pink.

I found that the light of higher lightness colours (red, green, blue) usually only have the colour of the light itself, while the light of lower lightness colours (light pink, lavender and purple) will reflect their own colour and the colour of the rainbow. Usually, the shape of shadow refracted by water is uncertain. For my design in the future, we can use this kind of changeable shadow to add a gorgeous effect to the work, and the brightness is basically softer than the light bulb on the microcontroller.

DIY Pressure switch

In my second journal, I want to share my experience of making a pressure sensor. You can control the brightness of the light by pressing the pressure sensor with different intensities. The tutorial on the pressure sensor is from the workshop of week 6.

Reflection:Although the method of making this pressure sensor is very simple, I feel very excited about the success of my first attempt. In the later design, I can make pressure sensors into different shapes, and even hide them in clothes.

Journal #3

DIY Capacitive Sensor and Expansion of the pressure switch

In my third journal, I want to share the process of making a capacitive sensor. In CPX, from pin A1 to pin A7 can sense capacitive touch, so I connected pin A1 to a piece of conductive fabric by conductive thread.

First, fix CPX on the non-conductive fabric with cotton thread, then place a piece of conductive cloth near pin A1. Connecting pin A1 and conductive fabric with conductive thread. Touching the conductive wires on the conductive fabric can trigger CPX light animation.

j3-code

I also want to share the process of controlling LED with a pressure sensor. In journal 2, I shared the process of using a pressure sensor to control CPX animation, then I attempted to use this sensor to control LED.  When I touch the wire with my hand, the light bulb will light up. Then I connected the sensor, and the light bulb changed its brightness as I pressed it.

FANXY – Wearable Patron Ghost

fanxy1


Concept

Do you believe in the existence of the soul?

Why are some people afraid of ghosts? Must they be evil?

Do you believe that everyone has a different patron saint?

The inspiration I got from various movies and animations made me want to create a soul with colours. All emotions have colours, even with sounds or smells. Fanxy is a wearable ghost that communicates with the owner, it is a concrete form of soul. It has four states: normal, chill, irritable and excited. It has a peculiar appearance: a regular left eyebrow, an angry right eyebrow, two eyeballs with hollow patterns, a serrated, hollow mouth and a dignified bow tie. It freely floats around the owner’s body, quietly guarding and healing the person. Fanxy helps you visually express emotions or states; it enlivens your life, and it is the most loyal pal of yours.

For its image design, Fanxy’s eyes are made of Tibetan beads, which are conventional crafts with Chinese Tibetan characteristics. The carved patterns on them symbolize nature, such as leaves, vines, etc., and also represent a spiritual pursuit of beauty and harmony. The reason for using that as eyes is to incorporate elements such as religion or gods to make Fanxy more psychic. You can see there is a black border around Fanxy, that is to visualize the ghost more clearly, to make the intangible soul tangible, or to frame the floating soul to make its energy intenser.

Fanxy is a significant iteration of my previous project “Watchghost”; that one is more like a prototype for Fanxy; if you want to know more about it, you could check out the link.


Interaction

The user silently recites an incantation to summon the patron ghost, Fanxy, and trigger its different states, as their inner world is tightly linked.

User wears & powers up Fanxy

Fanxy is awakened, in its pristine state, maintaining a yellow light. If the user is in a normal mood at the moment, without any manipulation, Fanxy will keep the same, quietly guarding the wearer.

User touches Fanxy’s left eyebrow

This point represents the user is chill; by pressing the arc eyebrow, Fanxy is activated the calm mode, emitting faint blue light.

User touches Fanxy’s right eyebrow

Now means the user is getting irritable or so; by pressing the raised eyebrow, Fanxy starts to flicker and remains in red, which is also a warning signal to the outside.

User touches Fanxy’s bow tie

At this point, the user is feeling extremely joyous or so; by pressing the bow tie, Fanxy is triggered a sound effect while becomes colourful.

<Inputs>

Invisible Switch: Capacitive Touch – Pin A1, A3, A6

<Outputs>

A1 – Blue loading animation for 2s and then CPX stays blue light.
A3 – A sound effect accompanies the 5s rainbow light animation, then returns to CPX initial state of yellow.
A6 – Red flashing animation for 2s and then CPX stays red light.

Objective

This project aims to realize the elements that fascinate me in movies and animations while combining them with my personal reminiscence to bring them into daily life.

Personally, I intend to iconify the image of a little ghost. The past assignment was just roughly to sew Fanxy on the sweater, yet I want to make it more portable and apply it to more diverse scenarios. Maybe I am still a person full of childishness. In my childhood, there was a doll that was my closest buddy, accompanying me day in, day out, so that I am a sort of old-school. During the pandemic, sometimes, I feel that I am an isolated island without any signal. As the original intention of healing, I really want to execute the concept to redeem myself. I believe some people would be similar to me, and I hope Fanxy could be stunning to you, heal you a bad day, bring warmness to both you and me.

While receiving a large amount of information every sigle moment, the advancement of AI technology often makes me fantasize about something fancy. Home automation, smart pets, smart toys and some other concepts also make me cannot wait to try them with wearable devices. Also, the current trend in design is paying more and more attention to inclusiveness. I believe that via the combination of tactile, sight, auditory senses, as well as the comprehensive consideration of safety and wearability, not only myself, Fanxy would be suitable for diversified groups including the preschool and special.

Fanxy does mean a lot to me; it is not just expressing certain emotions but a microcosm of mine, which uses the simplest form to achieve the perfect combination of electronics, aesthetics, childishness.


Wearability

ComfortFanxy is made of soft skin-friendly materials, with a plush feel, so the user will have an excellent wearing and tactile experience. Besides, it is very safe with no threat when using. Fanxy’s face is undulating – the eyes are three-dimensional, the mouth is hollow, the eyebrows and bow tie are with texture, driving people to touch it. Also, its eyes can be rolled.

DurabilityFanxy is very resistant to dirt and can be locally washed to keep clean. It is also very stable by firmly stitching, and not afraid of friction or exposure.

Usability: As the demonstration, I applied it to four usage scenarios, in fact, that would be more extensive. Fanxy can be worn or decorated around various parts of the body. Moreover, Fanxy fits in most daily scenes or sites, the only thing you need is a portable power bank to wake it up. Meanwhile, based on its interactive features and design elements, it is very easy to manipulate or trigger.

Aesthetics: Everyone thinks of beauty differently. I think Fanxy is beautiful with its own personality. It is what the soul looks like in my mind. Fanxy is an emotional, coloured soul. Its appearance is solid and flexible. Its design is very simple but childlike. To some extent, it is cute and iconic.

Reflections & Next Steps

My final project is an enhanced version of the previous expressive wearable, which is also the result of a better understanding of wearability. For a perfectionist like me, Fanxy still needs to improve in detail, such as more rigour material choice, much deeper considerations/logic in design, neatness of sewing. But overall, compared to the last assignment, I have improved a lot. For instance, the use of more suitable materials to diffuse lights, a more accessible interactive experience, finer stitches, etc., all being mentioned have made Fanxy more complete while basically reach my preset goal. Actually, I cannot wait to share Fanxy with my friends. I also want to take it back to China and show it to my family. My younger brother will absolutely love it.

The production of Fanxy makes me really proud. It is like my child, from intangible to tangible. I have witnessed its growth, at the same time, I have also grown during this process. Indeed, it is very fulfilling to realize a certain vision in your heart step by step. My concentration and patience have withstood the challenge when building Fanxy. In these few days, I have not stopped thinking or self-reflecting. Through this project, my sewing skills have been trained. More importantly, for me, not only the concepts taught in this course but also the understanding of the wearable field have risen to a higher level. Since when I got started in this field, I was in a panic at first. I felt that I know nothing, and I had to learn a bunch immediately. However, through several practices, I produced content that I want to express, which made me feel confident about the future. I started to trust myself, holding a certain understanding of this field. Thus, I know it, when I see an amazing wearable project again, I will no longer just be envious. Like I will use the theoretical framework I have absorbed to analyze and explore it, then finally internalize it into my insight. Thanks to this class, it makes me no longer resist using needles, programming, and gives me a chance to appreciate various materials, experiencing the meaning of interaction and so on. It always lets me feel the charm of electronic technology with aesthetics, exploring futuristic bodies and clothing. In the next stage, I will apply the skills I mastered this semester to various fields and combine them with complex projects. Via the course, I know that wearable technology is not only thriving in the fashion industry but also inclusive and can even change the world. All the experience in this class has also opened up new ideas for me, whether it is for my thesis year or the research direction for graduate studies. At this moment, I feel I am closer to my goal. Everything is laying the foundation for the future. I will keep exploring and researching, designing projects that can address more complicated issues, and be an expresser with connotations. Currently, I define myself as a raw artist, whereas we will see and you will know.

In the end, I really appreciate Oliva and my peers for making me feel such inspiring in a group full of creativity and ideas. You guys are awesome!

Hope all is well. See you in the future!
