* Little Details *

 Idea:
To create a wearable body circuit that promotes interaction by examining details. As the switches are found and turned on, LEDs light up.   

Materials:
10.5 M of 22GA Brass wire
3 volt battery and battery pack holder
Plastic Beads
5 Lilly Pad LEDs  (blue, yellow, green, white)
Silk Yarn

Process:

Final Piece:

Challenges:
 – Had a red and yellow light in the circuit made the cool colours dull.

–  Creating a second switch incorporated into the design.

–   Making sure connection was solid without soldering.
– Creating a flaw in the design small enough that people would still interact with.
 

Successes:

–          Creating the extra switch at the bottom of the piece.

–          Removed the red LED to increase brightness of other colours.

–          Created interest to second switch.

Future Improvements:

Solder LEDs Together.

Make a full body piece with many switches.

Fully resolve covering the battery pack.

Growth – Final Documentation (April 14)

Hi everyone,

Here’s a PDF of my final documentation for Growth,
including the new stuff I presented this past week:

Growth – Final Documentation

Abstract:

Physiotherapy is an often painful and arduous activity, which patients approach with 
loathing and impatience, and sometimes even avoidance. These negative attitudes and behaviors  towards physiotherapy can add considerably to the patient’s recovery time.

My project, Growth, adds a playful layer to physiotherapy by transforming it into a game-like experience with rewards and incentives, thereby increasing the patient’s engagement with their prescribed exercises.

The ultimate aim of the project is to elevate physiotherapy exercises to something that 
a user can ‘look forward to’, or even become addicted to, thereby increasing exercising frequency and speeding recovery.

Power Fist (Soft Sensor Project)

Having recently read about the fabulous TEI Superhero Design Challenge
(http://www.tei-conf.org/11/participation_/design-challenge/), I’ve been
wanting to create 
my own piece of superhumanizing attire.

Enter PowerFist, a flashy glove that imbues its wearer with ridiculously
awesome strength! As the wearer closes their fingers into a fist, the glove
will ‘charge’, and the 
emblem (a ‘P’, of course) will glow ever brighter,
showing its current power level.

Materials:

Black knit glove
Velostat
Neoprene (two sheets)
Conductive Thread
Conductive Fabric (iron-on)
Unholstery Foam
Red fabric
 (for the ‘P’)

3-AAA Battery Pack
Insulated wire
Circular LED array (scavenged from a flashlight)

Iteration 1:

The main component of this project was an LED array that would
change its 
brightness depending on the pressure registered by a
custom-made soft 
sensor. I used the tutorial for a Neoprene
Pressure Sensor (from How To Get What You Want,
http://www.kobakant.at/DIY/?p=65) to create the first iteration
of this component.

Method:


Step 1:
Cut two rectangular pieces of neoprene, and cut a tab out on each piece.

Step 2:
Using an iron, a small square of conductive fabric was attached to each tab

Step 3:
For each neoprene piece, conductive thread was sown on, with 4 lengths
parallel to eachother (and angled diagonally), and then attached to the
conductive thread on the tab.  The thread pattern was identical for each piece,
so that, when the two pieces of neoprene were placed against eachother,
the threads would form a network of X’s (this was to ensure that a circuit
was formed

Step 4:
A piece of velostat was sown over the conductive thread on one of the
neoprene 
pieces

Step 

5.
The two neoprene pieces were sown together to form
the soft pressure sensor. The soft sensor was then attached in series to the
battery pack and the LED array. This iteration proved unsuccessful — the
LED array did not light up, and was most likely 
due to the fact that the
resistance of the conductive thread, together with the velostat, 
reduced
the current to an amount that wasn’t sufficient to drive all 15+ LED’s on
the array (even with maximal pressure applied).

Iteration 2:

For the second iteration of the soft sensor, I decided to forego conductive
thread 
in favor of conductive fabric, to reduce resistance. This new soft sensor
was structurally similar to the one from Iteration 1, except that a piece of
conductive fabric was used in place of the network of conductive thread.

This worked perfectly! The LED array now gradually glowed or dimmed in
response to applied pressure.

Placement of Components:

The soft sensor was attached to the palm of the glove, in the area directly
beneath the fingers. The LED array was fitted with a layer of upholstery foam
(used as a diffuser), and affixed to the dorsal side of the glove. The battery
pack was velcro’d onto 
the wrist section of the glove. All these components
were then connected together electrically with wire.

Badass – Enhancing Social Alienation

Title: Badass

Concept/Objective: To create a wearable and fully functioning supermodern garment to be worn while riding the TTC which would deter others from getting too close to and/or interacting with the wearer.

If strangers come to close to the wearer, the garment will raise the collar to obscure the lower portion of the face of the wearer.

The Intended Scenario:

1) The jacket is put on and the Wearer enters the TTC.

2) There are a few people on the TTC, but the Wearer is not bothered.

3) The vehicle stops and a large number of people get on, the Wearer is a bit uneasy at the thought of being close to strangers.

4) A stranger comes within a meter of the Wearer and the collar of the jacket rises a little.

5) At the next stop, a few people get off of the vehicle but an even larger number of people get on, a few strangers are now within a meter of the Wearer, the collar of the jacket rises higer and begins to obscure the face of the wearer. The spikes which were previously hidden under the collar are now exposed.

6) The TTC vehicle is now very full and the collar is fully raised, giving the garment an intimidating appearance with all the the metal spikes facing outward.

7) The strangers who were crowding the Wearer have now backed off and seem a bit put out by jacket.

8 ) The Wearer relaxes, knowing that they do not look like someone that people want to come near, strangers move away.

9) Once there is no one within a meter of the Wearer, the collar lowers fully, revealing the face of the Wearer.

Parts and Materials:

– Alligator clips

– Mini USB cord

– LilyPad Arduino

– 2 Lithium Polymer Batteries

– Wire

– FTDI Chip

– Analog Distance Sensor

– Black Calfskin Leather

– 2 Servo motors

– Metal spikes

– Metal studs

– Black leather

– Black satin

– Black thread

– Sewing machine

– Interfacing

– 5 volt Regulator

– 3 volt Regulator

– Capacitors

– Snaps

Related Works: Barking Mad by Suzi Webster and Jordan Benwick, a coat that plays back the sounds of different dogs barking with increasing ferocity as a stranger approaches the wearer.

Challenges:
I chose to work with materials that I had never worked with before such as servo motors and proximity sensors, plus I have never sewn leather before. Purposely challenging myself, I knew that I would face some difficulties, but I ended up facing many more than I thought.  There were challenges with the code, voltage, and wiring that have lead to this piece being a work in progress.  Most recently, I got the circuit and code to totally work but when I went to rebuild and solder the circuit, it no longer worked.

Sucesses:  I am very pleased with how the jacket itself turned out, since I have never sewn a jacket before, let alone a leather jacket, I am happy with how it turned out.  Also, I have grown a lot in my knowledge of code, and the use of different components and mechanics.

Next Steps: Next, I will find out what is up with my circuit and why it is not being successful and then I will finish integrating it into the jacket itself. Then I will add the metal studs!

Head Dress to Impress

Idea/Concept

Inspired by the ancient Indian, Russian and Japanese head dresses, as well as the modern interpretations of the subject I wanted to create a wedding Head Dress that would capture images throughout the day, allowing the wearer the freedom of enjoying the festivities. It gives the user an additional collection of memories, from their point of view.

Intended Scenario

As soon as the bride puts on the Head Dress the camera turns on and continues to capture images throughout the day at the interval of approximately 2.5  minutes. At the end of the day you might have anywhere from 240-400 photos (based on a ceremony+reception that would last anywhere from 10-16 hours)

Parts & Materials

To construct this I used:

1.3 megapixel digital camera Arduino decimale                                                                                                                            2N3906 PNP Transistor                                                                                                                                                  Protoshield                                                                                                                                                                                    Header Pins                                                                                                                                                                                          9v Battery                                                                                                                                                                                                1N4004 Rectifier Diode                                                                                                                                                        Miniature Slider Power Switch                                                                                                                                            Arduino Power Supply

There is a lot of work done in the sphere of wearable cameras. Best quality I’ve seen are videos done by GoPro which capture action footage of various sports like biking, snowboarding, long boarding or downhill skiing.

Challenges



Coding is something I don’t understand and find extremely challenging. Especially when I can’t tell whether its not working because of code or a broken connection. I wanted to create a trigger circuit that would allow for timing intervals but encountered a lot of problems with making longer intervals.

This is the code I used:

Successes

I was happy with the weight and positioning of the device. As a wearable that is positioned on your head I wanted it to be as light as possible. However even though the finished project seemed heavier then what I would like it to be, it wasn’t too uncomfortable during use. I was also happy with the final design of the head dress.

Next Steps

final project: soft cyborg

soft cyborg

Title: soft cyborg
Concept: This mask was a continuation of my explorations from Wearable Technology 1 on how technology can be made more human and bring people back into their bodies as oppose to distracting from them. This mask was different from previous masks as it focused mostly on soft cyborg/human interaction. It was my intention to encourage the formation of a non-linear narrative between people and the soft cyborg.
The Intended Scenario: Ideally the soft cyborg would coexist in public spaces with people. Through its movements and interactions, the soft cyborg would encourage physical interactions to take place.
Parts & Materials: The base, eyelids, and nose are made out of handmade felt. The nose is made out of a combination of felt and conductive felt (made from a blend of merino and bronze wool). There are micro servos in the eyes and the circuit runs off of an Ardunio Pro Mini microcontroller and two 9V batteries. The conductive felt in the nose is connected to the circuit using conductive thread that has a crimp bead attached to it on the inside of the mask. The wires connected to the circuit also have crimp beads soldered to them. Everything is connected to the conductive felt pressure sensors with a little metal hoop so the circuit can easily be removed.
Related Works: This mask riffed off of my previous soft robot/cyborg masks. While I did look at other masks for inspiration, the final form emerged on its own.
Challenges: The biggest challenge with this project was refining the concept. The more I learn about the possibilities of incorporating technology with fibre constructions, the wilder my ideas become. I needed a lot of time to cull my initial idea down to something that was simple and doable. Working with conductive felt was a big challenge as well. My final use of the material was not as robust as I had intended it to be. Because the fibres moved around and in some cases felted more when touched repeatedly it was difficult to get consistent resistance readings. As such, the soft cyborg did not always respond when touched.
Successes: I was successful in creating a more refined form for the soft cyborg. I really find the extended nose to be a strong new development.
Next Steps: Next I need to work with making conductive felt a whole lot more. This includes trying to wet-felt conductive felt. Also, I would like to work with children to see how they respond to my masks. Beyond the technology part of this piece, I also intend to explore the potential for my actions/performance to contribute to the development of the soft cyborg’s persona.

Final Project: Earthquake Skirt

The Earthquake Skirt is a skirt made of debris that rumbles and shakes with near-real-time seismological data.  Beneath the layers of debris are three vibrating motors, which have their intensity scaled to the magnitude of the occurring earthquakes.

Concept

At its core, this skirt is about compassion.  One is literally wearing and being reminded of someone’s trauma.  Its relevance to fashion is that like fashion fads, natural disasters pass by us –especially those of us who are geographically immune.  How quick we are to forget about the ongoing struggle of victims in Japan, Haiti, Chile, China, and other places that major earthquakes strike but of which we never learn.

I wanted to play with the idea of glamorizing disasters, of bringing disasters into the fashion world by creating a scenario in which a person wears the debris of someone’s life.  I see this paralleling the torture of animals in the name of fashion items (fur coats, boots made from the skin of exotic animals, etc.), and in this way the piece becomes a big cheeky.  “Are those your new seal skin boots?  They match perfectly with your Chilean 2010 earthquake dress!”.

Research

In order to inform myself on the material process of the making the skirt, I had to do some research on debris from earthquakes.  I looked at many images from around the globe, ultimately deciding on a palette, materials, and shapes.  In addition, I researched other skirts that may have incorporated real-time data, but found only one: Nancy Paterson’s Stock Market Skirt.

A Study of Debris

The data is pulled from the United States Geological Survey website, which tracks seismological data from around the globe.

We all have some form of relationship with technology, and that relationship has a past, a present, and a future. How we saw and interacted with technology when we were kids, how we use it today, and how it will influence us in the future. I wanted to meld these ideas together, in a fantastical and costume-esque wearable that incorporated current technology.

When thinking about my past, present, and future relationship with technology, and what devices I currently consider dear to me, the idea of turning my iPod touch (Optimus Prime) into a retro-future style computer armband was an exciting prospect. I have always loved the old science fiction ideas of the future, and jumped at the chance to turn one into reality. In researching for this project, I found myself more and more wanting something also reminiscent of childhood: that idea of technology almost more than technology itself. When I was kid, we had a non-functioning keypad mounted on the doorway next to our basement playroom. While the keypad did nothing, it was exciting to pretend one needed a security code to enter the room: and that was enough. The technology itself wasn’t needed or necessary. Growing up I was also borderline obsessed with Calvin & Hobbes, and Calvin’s alternate ego: Spaceman Spiff. The adventures you can take within your own imagination can be more exciting than where technology could take you.

As exciting as the prospect of owning/making my very own futuristic computer-band, it turned out to be very hard to actualise. The iPod is sleek and slippery, and trying to simply strap it down with material to the arm was not an option. I was fortunate enough to scout out some plastic snap cases, which were barely more bulk than the iPod itself. With both a drill press and a hand drill, I created a variety of small holes to be able to sew through. I made a solid leather wristband, with large button attachments, as a wearable prototype only (no technology). While the design of the wristband itself was solid and comfortable, after trying to work with leather for the future-computer wristband, I decided to change tact as the aesthetic was not quite what I wanted, and the attachments weren’t functioning as well as I’d hoped. Finding a great shiny silver stretch fabric helped not only with the attachment design problems, but worked well towards my retro-future aesthetic. I experimented with size and shape of the wristband and holder, and came to a good middle point: something that was nice and big and costume-esque, but not too bulky and heavy to actually wear. I gave it shape with carved foam, in between layers of the stretch material. After wearing/testing one of the prototypes, I added some extra elastic to prevent the wristband from sliding down the arm for the final product.

Finishing the wristband and wearing it for the first time was very exciting. Due to the materials used, it’s not very heavy or awkward on the arm, and becomes less apparent over time. I especially enjoyed dressing up for the critique, as the piece called for extravagant play, and that great call back to childhood and imagination. Since the critique, I have continued to wear it (minus the rest of the gear, sadly) and the response to it has been pretty great. A lot of “Cool!”s and “Did you make that?”s, which is always encouraging. While the responses to this current wristband have been positive, there is always room for improvement. Every model I have made so far has been better than the last, and I look forward to developing it further. I’d also like to make some for others, and see how they wear on different bodies and with different lives. If possible, I would like to return to working with leather, as well as explore other materials to create other aesthetics. Once form/structure is further tweaked, adding some “useless” LEDs to add to the aesthetic could also be taken into account. As for deviating away from the costume application, and creating something more marketable, I have no interest in that. I am much happier to find fun and creative ways to engage the imagination beyond the scope of what technology can provide.
