I have just succeeded in interfacing fabric sensors with the sequencer program I posted the other day. Hooray!
What you have here is 4 strips of knitted fabric. These are acting as potentiometers. For a better description of how this is done, speak to an engineer because I don't understand the principles involved.
What they are doing though, is like so:
The bottom three strips each relate to one step in the sequence and are responsible for varying the frequency of a square wave outputted from the microprocessor. The top strip is responsible for governing the speed at which the program cycles through the steps.
In other news, I'll be visiting the CALL centre in Edinburgh on Thursday to learn more about the issues associated with IT interfaces for disabled people and see if I can figure out how to send my work in a useful direction and do the people of the world a useful service. Seriously, have you ever considered how much fun the internet is for the blind? Not a lot, right? And if you're not particularly dextrous I bet typing on a regular keyboard (never mind phones!) is a bit of a nightmare.
Anyway, I'd like to do something about this. Textiles are pleasing. A perfect environment to house computer interfaces in. Why not?
