The Third Eye – Ivy Sun (3183268)


Project Description

Eyes have long been regarded as “windows to the soul,” through which people can express or hide many emotions. In myths and legends, the eye is an expression of emotion and a symbol with symbolic meaning. The third eye chakra is located just between our eyebrows on our forehead. It is associated with the pineal and pituitary glands on the brain, but it is mainly an energy center. The third eye is the center for clarity, intuition, and foresight. It can help us see beyond the physical, three-dimensional world and be a center of mental, logical energy. This project is a concrete version of our third eye. It can also help us better connect to our intuition, guides, higher self, and even our subconscious mind. It is also served as a meditation process, a way to talk to ourselves and discover our inner self.

The Third Eye is a head-mounted wearable electronic device. Different LED light colours step by step to simulate dialogue with oneself in the mirror, which can be regarded as meditation, reflection, relief, and finally, a state of bliss and happiness. It is also a device to express oneself and emotions to the outside. It can be worn on the head, partially covering the face, as a luminous decoration of personality.

It has 4 states:

  • White – Innocent, The present
  • Crimson – Rage, The regrets
  • Azure – Sober, Just let go
  • Rainbow – Bliss, Follow the rainbow, follow your bliss

Light colour is triggered by switches, which are the eyelashes. Each colour lasts for seven seconds before returning to its natural white.

Construction & Pre-test:






Explanation of Design Choices

  1. The different colours of light set to seven seconds correspond to the composition of the rainbow colours, which correspond to white. The intent is to create a gradual process. From monochrome, colour and finally iridescent.
  2. The use of light and opaque fabric, to create the best light diffusion effect.
  3. Use fabric with flannelette texture on the back to keep it comfortable when wearing.
  4. Use golden thread to seal the edge, which is like a halo of sunlight covering the third eye.
  5. The silver strings below are designed to mimic moonlight and match with golden sunlight.

Lessons Learned / Next Steps

Through this assignment, my sewing skills have been improved, I am delighted. However, I still encountered a lot of troubles in practical operations. For example, the conductive thread was not well planned initially, resulting in contact interference, and the switch could not normally trigger different states. So I removed the eyebrow switch again, rearranged the connection position, and sewed it again to ensure that the circuit would work properly. So if I had planned and tried in the first place, it wouldn’t have been so inefficient. Next time, I will first ensure the position of each fabric piece and the wiring’s length, and then start sewing.

Also, the work is still not sophisticated enough. It is still a prototype. Moreover, it cannot be worn stably and independently on the head because I did not consider the power supply problem in advance. If a relatively light external panel can be connected, it may be easier and more stable to wear. Therefore, I must consider every detail in future exploration, ask more questions, and exchange ideas with the instructor. Problems need to be identified and resolved promptly. Obviously, the project should go through some iterations, and it can be further refined and genuinely wearable.


ConfiStand – Visualizing Your Understanding

Project Description

ConfiStand is a combination of the words “confidence” and “understand”. This wearable provides a visual indicator to the teacher about the student’s comprehension. The concept was inspired by when students remain silent whenever asked if they understand the material. As all students are different, some may feel insecure, and shy to verbally admit that they are having difficulty understanding in front of their peers. 

The wearable device is a badge that students will wear at chest level via a safety pin. Embedded into the badge are 10 neopixels and 3 buttons. The 3 buttons indicate the 3 different modes of understanding. The buttons are not the traditional push buttons but instead are snap buttons found on many clothes. The use of these buttons requires more follow-through to hear the snap but which psychologically provokes a sense of intent. The 3 modes are “I understand” which turns the lights to a rainbow, “I’m confused, keep explaining” which turns the lights blue, and “I need help” which turns the lights yellow/orange. There will be labels beside the snap buttons to indicate which one is which on the badge. Overall, these colours were psychologically chosen to provoke confidence and support instead of the traditionally green/yellow/red. For example, red is always seen as a negative colour, therefore I replaced red with yellow to indicate hope. 

Reflecting upon this wearable device, ConfiStand aims to visualize their understanding whenever asked without feeling the judgement of their peers. Additionally, it will allow instructors/teachers to scan the crowd and understand their status without individually asking. Instructors/Teachers will find this helpful as they will be able to adjust their teaching method to support students learning journey.

The Networking Bracelet – Trish

Project Description 

During professional networking events, it can sometimes be daunting for students to approach employers and recruiters. Hence my project is a simple networking bracelet that helps students identify who are employers and recruiters during in-person networking events. My wearable is designed to communicate information without any verbal cues. The Networking Bracelet has three different animation modes and colours to represent students, recruiters and employers. Students are represented by yellow because it is the colour of curiosity, youth and encouragement. This mode works by lighting up two NeoPixels on the circuit playground yellow in a crescent motion on each side. Employers are represented by blue because it is the colour of professionalism. This mode works by blinking all NeoPixels on the circuit playground blue to draw attention to students seeking employment. Lastly, recruiters are represented by green because it is the colour used to search on a location finder. This mode works by lighting up two NeoPixels on the circuit playground in a cyclone motion to show they are recruiting.

Project Context

Ice breakers are often great ways to get people talking and conversing especially if people do not know each other. One of the ideas that came to mind while working on this project is the idea of making it easier for people to approach each other at any kind of event, not just networking. The device is intended for versatility and can be modified to match any type of event and it is also an interesting way for people to express themselves. One of the projects that inspired my wearable device is the Gemio Band(Gemio n.d.). The Gemio Band uses advanced LED technology to create millions of colours and endless light effects that respond to music, movement and the people around. It connects with people with the band by pairing, and it sends light signals to communicate in a flash. You can be part of the show at concerts and events by pulsing to the beat, syncing with the DJ, or connecting to the crowd around you. It is the first wearable that lets someone change the design using snap-on tiles as easily as changing clothes. Someone can switch up their band’s tiles, colours and effects to match their look, mood or moment (‘The Customizable Smart Band That Lights Up Your Night’ 2018). 

Another project that inspires my work is the customizable bike light (Nelson 2017). In the project, the author defined colours in code and used them to make some fun animations with the NeoPixels on the Circuit Playground Express. My project used different animation modes to represent different types of people as previously mentioned. One important aspect of the design is colour because each colour represents something different. This project helped me in testing out different colours and animation patterns and each design had its own reason as to why it was created. The students’ animation was represented by crescent motion on both sides of the Circuit Playground Express that meet in the middle because it gives the impression of going around a room in its entirety. The employer’s animation is flashing to indicate signal attention to students, as sometimes students can find it difficult to approach professionals. Lastly, the recruiters’ animation which moves in circular motion much like the vintage location tracker systems to indicate that they are in search of potential candidates. The on and off function of the wearable is versatile as it can also be used to perverse the energy of the wearable but it can also be used to signal a ‘do not disturb’ function as the user is either attending to someone else or they are on break.

As my project used visual colours and patterns as a way of self-expression another piece of work that inspired my project ChroMorphous which is a type of innovation in the textile industry. The fabric is an active, user-controlled, colour-changing eTextile. With ChroMorphous colour-changing fabric, someone can control the colour and patterns of your clothing and accessories at any time, using only your smartphone (‘ChroMorphous – A New Fabric Experience’ n.d.). ChroMorphous is similar to traditional fabric; it can be cut, sewn, washed, and ironed. What makes ChroMorphous unique is that the colour-changing properties are controlled on demand. This work piqued my interest as it uses fibre optics to literally change the colour of any product that uses the material. Likewise, for my project, the idea is to use colour as a means of self-expression without the use of words.

Lessons learned and next steps

As I worked on this project one of the challenges I faced was the use of the button to change between states. As it may seem easy to use a  button to turn something on and off it can be a bit more complicated to incorporate several different states within to change from one mode to another. Something I learned is that it helps to incorporate a way to preserve energy by adding an off function to the wearable so that when it is not in use it can be put to sleep to save energy. This project was a new iteration to what I am working on for my thesis project which is a wearable device to help improve someone’s mental wellbeing. The next steps with the project would be to have the same concept incorporated on a badge which is what people are provided with at networking events.

The wiring is exposed in my beanie to worship and witness the process of how information is delivered to humans, The delicate and fragile wiring aka the ‘organs’ of the piece are showcased as a thing of beauty and a part of the showcase itself. The red light and pixel aesthetic of the Dot matrix go well with the grey and black colour scheme of Toronto.

Physical Distancing Restaurant Indicator

Since the start of the pandemic, there has become a sort of new restaurant edicate to practising social distancing. I’ve seen it done in several ways but one of the main ways is to have a puck or a card that you can flip over and one side means it’s okay for the waiter to come to the table and the other means not to come near. This in my opinion is a flawed design because the waiter still needs to come somewhat close in order to see the puck/card, almost defeating the purpose. This wearable offers 3 options to communicate to waiters at a much greater distance so they can see across the restaurant and not have to approach. This wouldn’t necessarily be something everyone wears but for the few who just want that extra level of protection. The device slips on to the user’s arm and has 3 LED states that can communicate to the waiters. The first is a flashing green light that indicates that you want the waiter to approach to order or ask questions or pay the bill. The second is a dripping blue light that communicates that you would like a refill or water. The third being a consistent red light meaning you’re good and no need to come close to your table. There is also a 4th state of just no LEDs. The states are changed by the user clicking a button to cycle through the different states.

Video demonstration:

I started off creating the circuit and making the code work how I wanted. Once I had that done I soldered the wires to the correct positions on the neopixel stick, then planned how I was going to assemble the device. Then began hot glueing all the parts together. Then used white tissue paper to defuse the lights. Once it all fit together and I knew it worked I used electrical tape to secure the separate parts to an arm band for the user to wear. 

This was the first time I had soldered since high school, and I feel like I did a somewhat rough job at that so that is something I know I can improve on for next time. Also if I hit the button to fast after previously hitting it it won’t work because it has to run fully through its loop before the button will activate another change of state. 



Glovgenie tackles the problems involved to perform basic tasks while wearing gloves outside and when it’s freezing cold! It’s difficult to read the information that you intend to through your smartphone or do simple tasks like checking the time, setting a timer, and flashlight.

This is a glove that helps you get light feedback and perform simple tasks without the hassle of using your phone or any other device to do so.

There is an Adafruit Circuit Playground Express that is located in between two gloves, the thumb is connected to GND through a conductive thread and the other two fingers are connected to INPUT_PULLUP  through a conductive thread as well. When either of the fingers touches the thumb, the circuit is completed and using these digital inputs different commands are sent to light up the neopixels on the Circuit Playground Express. The index finger enables the use of a flashlight and the middle finger can be used to set a quick short-timer.

PROCESS (Trying out gloves & capacitive/wires/conductive thread)



Adafruit Circuit Playground express

Conductive thread

Dollarama touchscreen gloves




Over the past few years, a lot of wearables have come out that act as an assistant to the mobile phone. Wearables like smartwatches have become mainstream and mimic certain functionalities that are accessible without actually having to touch a mobile phone.

Although the interface of a smartwatch seems accessible, it is essentially still a screen similar to a mobile. Both of them face a similar challenge in their usability during the winter weather. It’s difficult to remove gloves and use mobile with freezing hands as there is a lack of precise control on fingers to be able to use a touchscreen normally. There are certain products like touchscreen gloves that help you use a smartphone while wearing gloves but they aren’t reliable and still pose the challenge of precise fingertip control because of a thick layer on top of the fingers. The problem with most touchscreen gloves is that they are retrofitted with conductive patches on the tips of fingertips only. Fingertips tend to be dry and thus less conductive.

One of the projects that came out to solve this usability issue is GoGlove. It’s a wearable Bluetooth controller attached to embedded fingertip sensors. The controller gives you access to the major music playback features of your phone without ever taking your hands off your ski poles. Designed as a thin “inner” glove, the GoGlove can be worn on its own or under any pair of winter gloves. As opposed to relying on capacitive touch fingertips this glove integrates a magnet on the thumb and specific sensors on the fingertips of the index, middle, and ring fingers and one on the proximal phalange of the index finger. [1] Touching the fingertip and the thumb is detected as action and can be used to create multiple forms of input like single tap, double-tap, long/short taps, etc.

GoGlove inspired me to work with pull-up circuits rather than using capacitive touch fingertip sensors. The reliability of a pull-up circuit to detect an action is quite high as it isn’t affected by the humidity of the fingertips and relies on circuit completion that occurs when the thumb and a finger are in contact. While GoGlove uses magnets, the project that I’ve worked on requires nothing but a conductive thread to sense touches. Due to the narrowed down scope of this project to use digital inputs as sensors and lights as actuators, Glove Genie helps users access features like the flashlight and setting a timer using a circular array of lights on the glove. Further development to this project would be to connect the glove to a smartphone via Bluetooth and be able to perform quick actions like checking time, weather, calling or picking up calls, controlling music without removing gloves.

The other project that I came across is the Misfit Shine wearable smart band [3] which uses 12 circular dots for its user interface. The technique in which the 12 lights are used to communicate multiple kinds of information to the user is subtle, clean, and minimalistic. This project aligns with the principles of silent technology as well as using the minimal amount of resources required for its features helps in its efficiency and much longer-lasting battery life. This project inspired me to use a similar interface for the LED actuators to depict information for the timer and the flashlight.

Wearing Your Heart On Your Sleeve – Angelina Do (#3182746)

Project Title: “Wearing Your Heart On Your Sleeve”

Project Description

“Wearing Your Heart On Your Sleeve” is a wearable electronic exhibited in the form of a sweater. This sweater is an interactive experience allowing the user to activate programmed switches based on their emotions. “Wearing Your Heart On Your Sleeve” allows the user to express what cannot always be easily said. Have you ever had such a burning passion for someone, but words just can’t express how you really feel? Or on the contrast, have you ever felt such hatred towards another? A picture is really worth 1000 words, or in this case a wearable! This wearable consists of three different lighting modes to display the following feelings:

  • Magenta: Love (ascending scale – upbright chime)
  • Amber: Like (repeated note – neutral chime)
  • Blue: Dislike (descending scale – depressing chime)

When the wearer puts on this sweater, they will notice some digital buttons on their sleeves. On the right-hand sleeve, there is a copper heart (connected to GRND) which will act as a button to signify their choice. When pressing the large copper heart to one of the icons on the left sleeve (X, Neutral Sign and Heart), each lighting mode will appear respectively. X will signal blue, ═ will signal amber and ♡ will signal magenta. There is also a tone for each respected emotion to add for more user accessibility (colour blindness, deafness and vice versa).  I decided to create this wearable due to my own introversion. Sometimes I find it difficult to speak what’s on my mind, therefore I wanted to create a wearable to make communicating your feelings just a tad easier.

Iron Man Gauntlet Mk. 1 – Luke DAlfonsi




This project was inspired by ironman! (obviously) Using the circuit playground’s light ring as the palm of the gauntlet I attempted to recreate  iron man repulsors with both lighting and sound, don’t worry it doesn’t actually shoot lasers! I achieved this by positioning wire clips at the fingers of a glove, when these clips are grounded it activates one of 3 effects, thruster, laser, and disco mode.
