Last week, I showed this project at the ITP show. Overall I got a very positive response, especially from kids and people who work with kids and education. Unfortunately, I was not able to get any good footage from the show itself as I was stuck behind the display for the entire time. I know that some other people captured some good footage and I will post links to it here once I find out where they are available.

After the show I decided to re-write the Processing sketch using a different TUIO library – I switched from the TuioZones library to the Tuio library (from the reacTVision team). I decided to make this leap because I was unhappy with the performance of the first draft of my sketch. The main issues that I was encountering were that the sketch seemed to run rather slow and the color selection was not working well (users were not able to select multiple colors at once). I’m happy to report that the new version of the sketch works better on both of these accounts.

Unfortunately, I still have some work to do to improve the performance of the multitouch display itself.  First and foremost, I need to take apart the display to improve the finger tracking resolution. I suspect that I forgot to remove one or two of the filter layers from the original LCD (I hope this is the case as this would be relatively easy to solve). The other issue that I need to address is to procure a new glass mirror that will not bend out of shape, like my current plexi mirror.
