* 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

…and a whole lot of feather, beads and things.

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

Rachel Wingfield – Smart Textiles and Archilace

In January 2011, the Faculty of Design featured Rachel Wingfield as guest lecturer. I highly recommend watching it.  Wingfield and her husband are researching the use textile properties in architecture. The stuff they make is not wearable but their work and the materials they use definitely inspire wearable technology.
