[edit] Wanting some updates

If you know or found some information about who invted the touch screen consept? what company, a bit more history about it. Thanks —Preceding unsigned comment added by 213.225.93.250 (talk) 09:55, 20 November 2007 (UTC)

[edit] Somebody Please

Merge the page called "touch screen" into this one. Do the right thing. GeneMosher

There is also a need to integrate the touch panel page. —The preceding unsigned comment was added by 203.130.103.235 (talk • contribs).

I think the Touch Panel article can likely be deleted. I don't see very much information in Touch Panel article that isn't in the Touch Screen article.--gg4rest 00:17, 15 December 2006 (UTC)

Agree touch panel is redundant in view of this article Tt 225 13:14, 6 March 2007 (UTC)

I agree completely. Merging Touchscreen and Touch panel is a clearly good idea. The terms are absolutely synonymous. So.....who's gonna step up and do this???? (Not me, right now, I'm busy.  :-) NuclearWinner 21:39, 10 July 2007 (UTC)

There's a comment at the top of the page that suggests that there are techincial details related to touch panels that warrant their own article. I'm of the opinion that sort of technical information does not need to be separated from this article, and that it should be merged (with the information referred to at the top of this page added) 209.89.223.239 21:11, 21 July 2007 (UTC)

Merge done. Guy Harris 09:10, 12 August 2007 (UTC)

touch panels are a whole different ball of wax than just touch screens as they involve the various factors; tail, controller, bezels, etc. and this should warrant it's own article. —The preceding unsigned comment was added by Anneaholaward (talk • contribs) 09:52, 8 January 2007 (UTC).

Then create such an article (making it something that discusses stuff not mentioned in this article, rather than something redundant with this article such as the old "touch panel" page). Guy Harris 09:18, 12 August 2007 (UTC)

[edit] Game Controller

I'm removing the game controller section from this entry as a touchscreen is not a game controller. Just because a portable gaming device (Nintendo DS) uses a touchscreen for input does not make the touchscreen itself a controller. If this were the case, we would also need to include such items as buttons and switches as game controllers. —The preceding unsigned comment was added by Branin (talk • contribs) .

I think that a touchscreen as a controller matches the level of the other devices at Template:Gamepad styles. We don't include items such as buttons and switches because they are part of gamepads, keyboards, etc. If a touchscreen was a component of an input device (as a button is a component of a keyboard), then it would not fit with this list. However, since the touchscreen is the input method, it belongs on this list. -SCEhardT 01:40, 8 February 2006 (UTC)
The DS touchscreen is part of the control system along with the buttons. It is not a separate controller. There are not "touchscreen" game controllers that you can buy for home console use, just as there are no game controllers that consist of a single button or switch, and this is why none of these things belong in a template of game controllers. To be honest, the whole template seems a little annoying, esp. on this page and on "flight yoke". JohnnyMrNinja 02:03, 4 July 2007 (UTC)

[edit] Removal of unnecessary Advertisements

how can a device already in the market (touchscreen) be popularized by an operating system not yet released? (windows vista) If windows vista does indeed ship with built-in touchscreen support, and it actually sees widespread use, only then it will make any sense. as it is, i'm kicking it off as advertisement.


Quit making changes to links for deceptive purposes!

[edit] 3rd Type of infra-red Touchscreen

There is also another type of infra-red touchscreen. One that uses two or more line scan cameras such as those made by Nextwindow.

[edit] Touchscreen Technology

Can anyone explain the diffence between the new "Optical Imaging" technology and the technology already explained under the "Infrared" heading? I'm thinking that "Optical Imaging" should be removed, but "Infrared" should be updated to include a few of the additional details from "Optical Imaging".-Atomic 18:01, 23 May 2006 (UTC)

Infrared generally uses a combination of IR transmitters and receivers, and performs "line scans" to locate an object.

Optical imaging is rather different, in that it basically uses cameras and light (sometimes IR, but not necessarily), and the touch is where the shadow is. It requires a bit more processing, but the cost is largely independent of the screen size.

[edit] Multi-touch

Is it notable enough to divide up the technologies into subsections based on whether they are capable of multi-touch sensing or not? — Omegatron 00:03, 1 November 2006 (UTC)

  • I think it is, that information would be highly valuable. Blue Dinosaur Jr 18:48, 1 December 2006 (UTC)
  • Agree with editor above, multitouch is good stuff but badly covered here. I wonder if more than just iphone use it. -Ryan Sullivan, 200702202345 estm

[edit] Missing historical development and market data

Anyone knows this: What was the first commercial product category with touchscreens? What time period did they become dominant? MaxPont 11:56, 3 November 2006 (UTC)

[edit] What about Inductive Types

Should a section about Inductive (or magnetic) touch screens be added?

An Example of an Inductive types of screens technology is availble at: http://www.pencomputing.com/features/wacom_digitizer_comparison.html —The preceding unsigned comment was added by SpadenMarvell (talk • contribs) 16:14, 29 March 2007 (UTC).

[edit] touchscreens and blind users

One of the issues at many public places and which blind people face constantly is the need to operate a touch screen. I´'ll conduct some research on this, although I doubt this issue has been known throughout not more people who use them but rather the ones who are unable to use them.

[edit] Touch resolution

I came to this article to find out what kind of resolution a touch can have. None so far. Does anyone have the inside gossip on what area (centimetres or pixels) is triggered by a touch (finger, stylus, etc) and how a mouse click (x, y) is defined from that, whether a block activation can be triggered (e.g. for use by a paint program), etc, etc. 89.242.85.116 19:03, 3 August 2007 (UTC)

[edit] Microsoft Surface

Is that a touch technology relevant to this article? If so, presumably the generic nature would be described and the Microsoft device mentioned and referenced in the external links. 89.242.85.116 19:03, 3 August 2007 (UTC)

[edit] Ergonomics

Anything? Occasional use in a kiosk application is one thing, using one on the desktop on a daily basis ... is it practical, is it just asking for RSI? 89.242.85.116 19:03, 3 August 2007 (UTC)

Thanks :-)

[edit] Graphics tablet/screen hybrid technique?

The section "Graphics tablet/screen hybrid technique" in the "Technologies" section needs to be rewritten or removed, as it doesn't describe a technology but rather an application. Probably it should be changed to describe the technology behind the application (I think it's inductive). Dan Griscom (talk) 12:05, 21 November 2007 (UTC)

[edit] Touchwires

An early form of touch screen was invented at the Royal Radar Establishment in the sixties and was used for experimental air traffic control systems. The Marconi and Plessey companies were involved. The Flight archives contain some details such as the following referenced article: http://www.flightglobal.com/PDFArchive/View/1967/1967%20-%202312.html KSE (talk) 20:18, 23 November 2007 (UTC)

[edit] Which applications are used in which products?

I came to this article to learn how the touch-screen worked on my computer. From this article, there is no way of knowing which of the many technologies my device uses. All the many types are simply listed, and its impossible for the layman to know which type is used where.Landroo (talk) 04:29, 18 March 2008 (UTC)

Its generally beyond the scope of this article if you ask me, generally the most common type of touch screen is the resistive, coming second is usage is capacitive, In consumer devices such as PDA's and Laptops/Tablet-pc etc. A 'easy' way to determine the difference between the two is that a resistive touchscreen can use an inert plastic stylus or even any sort of relatively pointed object(pen,fingernails), while a capacitive touch screen requires a finger (or some other conductive object) and wont work with non-conductive pointed objects. --58.110.132.123 (talk) 20:50, 27 March 2008 (UTC)
Along the same lines, it might be useful to include a common product with each type. For example, the Nintendo DS is shown in the article, but it isn't clear why it was chosen. It could be used as an example of the use of a capacitive touch screen, while an iPhone would be a logical example of the use of a capacitive touch screen. --Wikipedia XP (talk) 21:50, 7 April 2008 (UTC)

[edit] Diffused Laser Imaging

The Diffused Laser Imaging section doesn't seem to give any external references, and so far I haven't been able to find any other information on the web about this technology. Does anyone have any links for this? —Preceding unsigned comment added by 77.103.194.138 (talk) 23:41, 16 May 2008 (UTC)
