Hi, I have been researching Multi-Touch for the past year as a Hobbyist, and I consider myself somewhat well versed in the technology:)
While that method would definately work, its obviously going to be cumbersom and not portable at all. I have been experimenting with a method of Multi-Touch that uses an array of Phototransistors, and I currently have a 8x8 Array working very well(3x3 Inch active sensing area, plenty to cover the FreeRunner's screen). Its only issue is speed, which is going to be fixed soon with my Digi-Key order that is on its way. Mine obviously isn't perfect either, when I built it I had a more Laptop/Tablet shaped device in mind(just because the array is ~1/4 inch thick), but I do believe it will be easily adaptable. Here is a link to my site where I have a video and explaination on an older test I did: http://www.xelapond.com/dotclear/index.php?post/2009/06/04/Code%2C-Schematics%2C-Diagrams And here is a picture of my newest version, 8x8 array: http://www.xelapond.com/files/r1-8x8-angle.jpg In the near future I plan on somehow interfacing this to the freerunner. I will probably have to separate the screen from the device, and place this behind it(so I can interact with elements on the screen). I'm very passionate about Multi-Touch, if you do get anything with a WiiMote working, be sure to post a link+vid:) I'd love to see it. ~Alex Teiche On Sun, Aug 30, 2009 at 4:56 AM, Lothar Behrens <lothar.behr...@lollisoft.de > wrote: > Hi, > > I have seen this video and due to a wide angle, a similar solution may > be adaptable: > > http://www.youtube.com/watch?v=5s5EvhHy7eQ&feature=related > > Any comments? > > Lothar > > -- | Rapid Prototyping | XSLT Codegeneration | http://www.lollisoft.de > Lothar Behrens > Heinrich-Scheufelen-Platz 2 > 73252 Lenningen > > > > > > > > > > _______________________________________________ > Openmoko community mailing list > community@lists.openmoko.org > http://lists.openmoko.org/mailman/listinfo/community >
