Thin Film Transforms Any Surface Into Touchscreen 81

Posted by samzenpus from the peel-and-stick dept.
kkleiner writes "Open up a cardboard tube, roll out a transparent film just millimeters thick, apply it on a flat object and *tada* you've got an interactive touch surface. Cambridge-based Visual Planet just launched its new massive-sized multitouch thin film drivers so you can create touchscreens from 30 to 167 inches in size! Their touchfoil is a transparent nanowire embedded polymer capable of sensing the touch of a finger, or even pressure from wind and translating that to a computer interface. It works on glass, wood, and other non-conductive surfaces."

  • I would imagine any film above 1mm in thickness would be pretty hard to roll up into anything resembling a reasonable diameter.

      Um, last I checked a millimeter is pretty small. I can roll up all sorts of things to a reasonably thin degree which are much thicker than that(including one of those schnazzy silicone gel keyboard things).

      It's a transparent flexible touch surface...and you're complaining because it's as thick as card stock?

        Even 0.5mm overhead projector film is pretty hard stuff, silicon gel is very low density compared to plastic films as is card. I would expect a rolled diameter to be around 25-30cm which is fine for the 167", but a bit much for the small 30" versions.

      It annoys me that people think HDTV is good. In fact as far as DPI resolution goes, they're pretty much in the suckage range. My 5-6 year old Dell laptop has a 1920x1200 resolution 17" monitor.

          Thyat being said, I *do* use it for development, at least tweaking bits of code on the fly with VIM.

          But I, for one, would *love* a 200-dpi(N900 is ~230, regular monitor ~100), 20' or so monitor, because it would mean you could use anti-alised fonts and such without it looking blurry and odd. It'd also reduce the need for AA in games, though the total number of rendered pixels would make up for that.

    ... touch screen kits available about 15 years ago. Flexible transparent plastic film that one could stick to a monitor (or whatever) with logic to emulate a mouse (serial back then IIRC). Maybe a hundred bucks or so to do a 12 or 14 inch monitor. No big deal.

    They were great out on the shop floor. Some of the mechanics were in the habit of using (pointy, sharp) tools to tap touch screens. So anything that could be peeled off and replaced without having to scrap an entire CRT was great. Yeah, CRT. Get over it, kid. And get off my lawn!

    This appears to simply be an input device that is rolled out over an existing screen. Kind of neat, but not exactly worldchanging, and quite far from "transforming ANY surface into a touchscreen device". It might be able to record inputs, but the user would get no feedback without a screen or something like that.

    If this was a DISPLAY that thin, then this would be groundbreaking.

      Actually, you don't need a screen, but if you stretch your definition of "something like that" you're on the right track. We have lots of input devices that don't have screens attached: doorknobs, handles, tuning knobs, buttons, switches, pedals. This could be imagined as an alternative to all of them. Put it on a piece of glass and you have an input device that lets painters "trace" pictures from real life, just like the renaissance masters.

  • I saw something similar demonstrated at CeBit [wikipedia.org] in 2008. It was made by a Chinese company, and they applied it to a bunch of HDTVs on the scene, and let us operated it minutes after applying it (using Vista's tablet features).

    Perhaps they didn't use nanotechnology, but it worked fine, so who cares what the underlying tech is?

    And it was certainly not "milimeters" thick. More like 1/4 of a milimeter.
