FTIR – multi-touch

October 23, 2008

Here’s video of the FTIR screen that i made a few months back. It’s surprised me as to how easy it was to build and get working. The hard bit (and it is complicated) is to interpret the blobs on screen and make them do something interesting [i’m yet to achieve this 🙂 ] Currently i’m using a mixture of reactivision / Max/msp / Touch designer FTE to interpret and manipulate the data. I’ll upload code and patches in the coming weeks.


It’s been quite a few months since I first ordered my xbee modules and today I finally had a little time to plug them in and do some testing. To my surprise it was a fairly simple task to get them to send and receive messages between two notebooks using maxstream’s X-CTU program. X-CTU is a tool made for programming and updating xbee modules it also comes with a terminal which comes in handy at times. Getting the xbee’s talking in Max/MSP seemed to be a sinch as well. You simply need to set up a serial send and receive patch and there you have it, small and fast wireless solutions. Here’s a short video of what I did today and you can download the max patches that I used for this demo. I can’t really see a practical purpose in using xbee modules in this way but it seemed to me to be a good starting point to get my xbee projects started.

My aim for the future is to create a wearable system for choreography using these small xbee modules. Rob Faludi has an Xbee direct blog entry that I hope to get going in the next few weeks.
