Team 1 – Colourglove

The beginning

Of this project visually impaired and blind people are the target group. After intensive brainstorming, our project has developed into a wearable with a colour recognition system. It is certain: We want to make colours audible!

Colour recognition for visually impaired

As a starting point for our development of the Colourglove a tutorial from the Internet served us. (http://www.makerblog.at/2015/01/farben-erkennen-mit-dem-rgb-sensor-tcs34725-und-dem-arduino/)

At first we work with an arduino uno and a Flora Color Sensor (TCS34725) from Adafruit. If you hold an object on the sensor, it evaluates the specific red green and blue values and gives appropriate feedback for the different colours. The servo motor, which initially took various positions, is now replaced by a loudspeaker, which provides an acoustic feedback.

First experiments: A simple electric circuit

In the beginning the different elements are only connected with crocodile clips and breadboard. Later the electronic components will be sewn together with a conductive thread on a glove. Our prototype is a small finger cover made of felt on which the colour sensor is attached.

Next step: Contact the target group!

Because we personally do not know anybody affected, we have turned to an Internet community to find out what the target group thinks of our project idea.

On this occasion thank you for so many comments, remarks and constructive criticism!

Here is a small extract of our notes from the community’s comments:

Basically exciting and useful idea BUT there are already many professional devices / apps with colour recognition and speech output

– Difficulty: colour recognition must work reliably
> Solution: Expand colour spectrum in our code for the lilypad arduino

What is the added value / “USP” of Colourglove?
> Solution: Artistic aspect / pretension & focus on DIY Wearable to replicate instead of luxury electronics

– Some blind people want be inconspicuous in everyday life
> Criticism: Glove with sensor is too conspicuous

Difficult target group fully blind people: They do not know what colour is
> For them it’s more a feeling, not something visual
> Aim: convert the “feeling” of colour into output tone

Next step: Concept development based on the influences of visually impaired

Thanks to the feedback of visually impaired and blind people, we are thinking about revise and developing our concept.

Here are some keywords:

– Too much existing advanced technology
> For this reason: Use in art context and not in everyday life

– Idea: Integrate Colourglove in an interactive museum visit?
> a lot of things often remain hidden for blind people, even despite audioguides e.g.

And now: Back to the technique used …

Our next step was the change from arduino uno to a lilypad arduino.

Problems with compatibility

Unfortunately, our colour sensor from adafruit is not compatible with arduino lilypad. So we buyed a similar adafruit FLORA v3 and finally it works!
