Argitoth Posted May 11, 2008 Share Posted May 11, 2008 http://www.cs.cmu.edu/~johnny/projects/wii/ Right there, scroll down to the 2nd video, later in on the video he shows you how to turn your LCD into a touch screen. I'm just wondering though... isn't that bad for your LCD? Won't it get scratched and such? Quote Link to comment Share on other sites More sharing options...
L.T.W. Posted May 11, 2008 Share Posted May 11, 2008 Yeah that guy is a genius. There was a thread about Head-Tracking VR Displays from this guy a couple of months back. About the scratching... I guess you can always buy a protective sheet for the screen. Kinda like the one for a Nintendo DS. Quote Link to comment Share on other sites More sharing options...
Argitoth Posted May 11, 2008 Author Share Posted May 11, 2008 any help on finding a protective screen? http://www.posr.us/store/pc/viewContent.asp?idpage=5 ? Quote Link to comment Share on other sites More sharing options...
Dhsu Posted May 12, 2008 Share Posted May 12, 2008 Probably don't have to touch the actual screen, just get your finger close enough to where you can tell where you're pointing. Quote Link to comment Share on other sites More sharing options...
Argitoth Posted May 12, 2008 Author Share Posted May 12, 2008 Probably don't have to touch the actual screen, just get your finger close enough to where you can tell where you're pointing. Not leaning on something would be quite painful after an hour. WAIT... that might just be crazy enough to work! Your elbow can lean on your lap or desk while you point and click in midair, no need to be near the screen, just point! Quote Link to comment Share on other sites More sharing options...
The Pezman Posted May 12, 2008 Share Posted May 12, 2008 LCDs are being phased out anyway. I don't know how resistant LED monitors are to scratching, Quote Link to comment Share on other sites More sharing options...
Argitoth Posted May 12, 2008 Author Share Posted May 12, 2008 LCDs are being phased out... For what, exactly? Quote Link to comment Share on other sites More sharing options...
L.T.W. Posted May 12, 2008 Share Posted May 12, 2008 For what, exactly? is it OLED TV? Quote Link to comment Share on other sites More sharing options...
The Pezman Posted May 12, 2008 Share Posted May 12, 2008 Not O (organic) LEDs specifically, but rather the idea of LED lighting. It's much better than LCD screens for a variety of reasons. In addition, LED monitors don't require a backlight, which means that they can display true black, save power, and give richer and more accurate colors which will look the same regardless of the angle (remember the early LCDs which changed to photonegative when you looked at it from the side?). Macbooks are starting to make these available, and with the next refresh I think they'll become standard. I don't know how any of this pertains to touchscreen technology, but since Apple is working on that as well I'm sure it can happen. Quote Link to comment Share on other sites More sharing options...
Flik Posted May 12, 2008 Share Posted May 12, 2008 Touchscreen panels do not hurt LCD panels if installed properly. An ideal touchscreen setup will have multiple layers starting with the actual LCD panel, then a thin sheet of glass, then the touchscreen, then a protective layer. I've got a Panasonic Toughbook CF-28 that I've been rebuilding. The protective mylar sheet was worn to shit from useage, but after carefully peeling it off the touchscreen layer and removing residue it's completely untouched. Just need to put a new protective sheet over it and all is good again. If I lift off the touchscreen layer and the sheet of glass the actual LCD underneath is pristine. Granted, building your own touchscreen can be as simple as putting the touchscreen overlay directly over the LCD panel. The overlay will actually help protect the original display underneath, but you just need to make sure you don't hammer on it. A good touchscreen won't need much pressure to pick up on where you touch anyway. Also, I'm a douche and did not watch the link provided. I'm just saying what I know Quote Link to comment Share on other sites More sharing options...

I'm just wondering though... isn't that bad for your LCD? Won't it get scratched and such? Stick a wad of felt on the pen's tip, making sure it doesn't obstruct the LED that the Wiimote looks at. Problem solved. Also, is there any reason you couldn't just use your mousepad as a tablet? Man, now I need to buy a Bluetooth receiver. This stuff is cool.

Dhsu Posted May 12, 2008 Share Posted May 12, 2008 Well the point of a touchscreen is the screen tells you where to touch. Quote Link to comment Share on other sites More sharing options...

The Pezman Posted May 12, 2008 Share Posted May 12, 2008 Interestingly enough, is now a featured video. The premise is essentially the same. Quote Link to comment Share on other sites More sharing options...
Argitoth Posted May 12, 2008 Author Share Posted May 12, 2008 I think that the wii solution is much better. You don't need a box, and the method of tracking isn't as iffy. You need lots of light for the camera to work. Quote Link to comment Share on other sites More sharing options...
