Multitouch display, build your own: preparing a silicone rubber layer, video howto!
When I tested for the first time my homemade multitouch display setup, I was too excited at the beginning to complain about the lack of sensibility. I had to press hard on the rear projection film to let the webcam detects the "blobs" of the infrared light bounced out of the acrylic. Later I understood this and I decided that it was the time to get a compliant surface made of silicone rubber as I was reading on the NUI Group forums.I had a lot of doubts regarding the preparation because, of course, I never used this kind of material...
Multitouch display, build your own: silicone rubber preparation video in progress
After I successfully tested the sketch paper I promoted the silicone rubber layer to the status of "useful". So I proceeded to acquire from the camcorder the video of the silicone layer preparation that I shooted two weeks ago.Actually the video is nearly two hours long, so I will take some time to me to edit it and shorten to a more reasonable lenght but without loosing important informations. So, if you're going to prepare a silicone rubber layer by your own and you have particular doubts or questions, feel free to comment in this blog and to ask, so...
Multitouch display, build your own: paper on the silicone rubber layer
Thanks to the first great suggestions from Cirrus and Cerupcat from NUI Group, this morning I tried an early workaround to solve my problems with the silicone rubber. Some indications came out also from Gravano and, actually, we're quite sure that the silicone rubber failure is most probably due to its excessive stickiness. This silicone rubber stikiness is the cause of the high cohesiveness of the rear projection surface on it and this frustrate the whole screen surface setting off the FTIR effect without any finger touch. Most probably this is why any other touch is not detected and why...
Multitouch display, build your own: silicone rubber layer first test
I've just completed the frame for my multitouch display and I could not resist from making an early test tonight!To be honest, I have nothing to be enthusiastic for...This is because this first test went really really bad. I had no usable "blobs" at all! I made also a short video that from the IR camera's view shows no blobs with the rear projection film applied. To be more precise, I had great effect on the bare silicone layer, the blobs were really clear and fast responding. As soon as I place the rear projection film on it all that...
Multitouch display, build your own: a compliant surface with a silicone rubber layer
Finally I arranged to prepare a silicone rubber layer to use in the multitouch display. I will use it to improve the coupling beetween the plexiglass and the rear projection film so that the display will be more sensible to finger touches and will require no more hard pressing to detect touches, yes, it is also an hope! <img src="http://www.diniro.net/fabbblog/fabbbultitouch_silicone_rub.jpg"> If you're trying to do the same don't worry! I video recorded the whole process and I...
Multitouch display, build your own: silicone rubber and a wooden frame
Finally I decided to build a wooden frame for my multitouch display. Basically I'm trying to build a light frame that may hold the plexiglass with the alluminium frame holding the IR LEDs together with the projection surface and the compliant surface that I'm going to make with silicone rubber. Here you can take a look at the actual stage of the wooden frame, it is quite complete, the glue is drying! On the right side you can see the silicone rubber I bought to make the compliant surface.Once the frame will be ready I hope to handle more comfortably...
