Microsoft is talking a lot about the importance of touch input to the Windows 8 experience in everything from tablets to high-end desktops. To show just how far you can go with touch, Microsoft demonstrated a PC running Windows 8 connected to an 82-inch touchscreen that can support up to 100 touch inputs (or 10 simultaneous users).

On the other hand, instructors use black/whiteboards etc, so there's a potential use case in education, or, in fact, when doing demonstrations or presentations, but I fail to see how Windows has much to do with that, as in the end application support is what matters more.
Of course, if that means that there is a decent multi-touch API integrated into Windows 8, this may be of some interest.

Still, a bit too flashy for my taste. Rick83 Reply RE: Gorilla arm by ananduser on Wednesday, February 29, 2012 Nothing beats Apple flashy-ness. MS can try all they want. ananduser Reply RE: Gorilla arm by tipoo on Wednesday, February 29, 2012 True, but with a wireless keyboard and touchpad or mouse that could be kind of neat. I'd still opt for the regular TV plus connected HTPC though, that way you don't have to throw the whole thing out when something is outdated. I wonder if they'll work voice control into it, that could be good for home theatre. tipoo Reply RE: Gorilla arm by mcnabney on Wednesday, February 29, 2012 Welcome is 2007, except I use a 100" screen. mcnabney Reply RE: Gorilla arm by Kepe on Wednesday, February 29, 2012 You are absolutely right. Imagine (if you aren't already) sitting in front of your desktop PC. Now imagine if its monitor was a touch screen and you had Win 8 installed. Now imagine using your computer by reaching all the way to your monitor and touching it to accomplish something. I can't even reach my monitor without leaning forward. Can you imagine anything that could be *less* ergonomic? Neither can I.
Touch UIs only work when you can have the touch screen near your body and at about elbow height (or in your hand if it's a handheld device). Sure it would be cool gimmick for desktops, for about two minutes, in which time your arm will start to hurt and you'll notice how much easier it is to point at things on your screen using a mouse.
The Metro UI will be a huge failure on desktops. Maybe it would be ok if you could split your screen so that the other (say, right) half would be where the Metro UI with its live tiles resides, and on your left you could have the regular Windows desktop. I played around with the Developer Preview quite a bit when it came out, and found the Metro UI to be hugely restrictive and hard to operate. You just can't do what you want with it. Want to launch a program? Good luck trying to find the program search thingy and then typing in the name of the program you need. Instead of just going to the start menu and finding all your programs listed alphabetically there.
Windows is a platform on top of which applications run. Being able to quickly and effortlessly find and launch the applications you want is the main functionality. Not a fancy (touch) UI that shows the latest Facebook posts of your "friends" and the weather outside.
Well anyways, downloading the Consumer Preview now. I hope they have done something to make the thing less crippled. Kepe Reply RE: Gorilla arm by thrawn3 on Wednesday, February 29, 2012 I mostly agree with you but you forget one interesting way of applying this technology and that is Microsoft Surface. From what this article is saying it sounds like they have rolled in a lot of the same code into Windows 8.
I don't think there are any Gorilla arm problems with using a tabletop display and touch surface.

I haven't tried Windows 8 yet but the Consumer Preview is already downloading and I will see soon enough what I think of the design. thrawn3 Reply RE: Gorilla arm by Kepe on Wednesday, February 29, 2012 When I said "Touch UIs only work when you can have the touch screen near your body and at about elbow height" I meant things like the Surface. You need to have the touch screen at ~elbow height, close to you and tilted upwards for it to be ergonomic to use. Then it will work. Kepe Reply RE: Gorilla arm by mcnabney on Wednesday, February 29, 2012 Even then, imagine using this for an extended period of time?

Sure, playing with it for 20 minutes is neet-o. Think of using this for hours... Sorry, slight mouse movements and finger twitches when typing are far far far more usable than a touchscreen. I get annoyed using my smartphone's touchscreen for more than 30 minutes. mcnabney Reply RE: Gorilla arm by Chudilo on Wednesday, February 29, 2012 You, sir lack any sort of imagination. Imagine a desktop that is design with a touchscreen surface in mind (and By desktop I include the desk) If a High resolution (high DPI, mobile phone like pixel density) Multi-touch Monitor is anchored to your desk at about a 45 degree angle directly in front of you with a physical keyboard (that won't change until they have piezoelectric keyboards that will let you feel buttons on screen) at the bottom of of the display. (no mouse).
Precise (mouse-like) input for CAD and Photoshop is handled by moving stylus directly on the screen.

That is actually a more natural way of interacting with your computer. That's right, more natural then a mouse. You can drag windows by dragging them. select things by touching them. The current Chudilo Reply RE: Gorilla arm by This Guy on Thursday, March 01, 2012 Sounds like a touch screen laptop with a fixed screen angle, like the acer iconia w500. Using one for six months, I agree that it is often more natural to touch the screen than to use a keyboard/mouse or pointing stick.

The biggest flaw with these types of device is that there is not a touch screen element for precise input. Why can't Microsoft add a small box to Windows which you contol by rolling your finger? When you place your finger in the box, roll it twice to configure then the box works just like a pointing stick.

I'm calling it a roll box :) This Guy Reply Subject Comment Post Comment Please login or register to post a comment.

IDT at CES : Touchscreen Controllers and Display Port Solutions

by Ganesh T S on 1/13/2012 6:09:00 PM
Posted in Trade Shows , CES , CES 2012 , IDT , Touchscreen , Displays

Home theater enthusiasts might identify IDT (Integrated Device Technology) with the HQV benchmark and video processor. That division of IDT was sold off to Qualcomm last September. But, that didn't stop us from stopping by IDT's CES suite to understand the reasons and also find out more about the products introduced by them at CES in the CE market.

While application processor manufacturers get a lot of attention for their SoCs, a good CE product needs more than just a good app processor. How many times have we seen a good tablet let down by sub-standard touchscreens or bad audio? It is quite interesting to analyze the mixed-signal ICs behind these technologies. IDT provides multiple mixed-signal solutions for touchscreens, audio codecs, video display controllers and power management solutions.

Capacitive Touch Controllers

Last year, IDT demonstrated the first PureTouch capacitive touch screen controllers, and this CES, they showed off a few design wins.

 


The Hanvon e-Reader (popular in the Chinese market) uses two LSD6107 controllers to provide the two sliders on either side of the e-Ink screen.

This year, IDT launched and demonstrated their next-gen PureTouch single layer multi-touch capacitive touch screen controller. Most capacitive touchscreens are dual layer (for a good overview of the various touch technologies available, refer to this (PDF) short course slides). By using a state machine design rather than a microcontroller, IDT claims both power consumption and cost are reduced compared to other competing solutions.

Display Port Solutions

Display Port is stepping up its game by offering more features necessary for the PC market. With eDP (Embedded Display Port), they are also targeting tablet panels (which are predominantly LVDS based right now).

IDT presented two innovations in this space. The first one invovled timing controllers for the PSR (power self refresh) panels which retain a displayed frame in a local buffer and can put the source driver in low power mode if the screen contents are not changing. Thus, the driver doesn't need to really keep refreshing the display's frame buffer again and again. This is part of the eDP 1.3 specifications and IDT is currently sampling this timing controller.

For desktop displays, IDT was also demonstrating a  member of the IDT PanelPort ViewXpand family, the IDT VMM1400 multi-monitor controller. It allows the user to connect up to four monitors with different resolutions over a single Display Port connection. A three monitor setup with this controller was also on display at the Display Port booth.

In addition, IDT also demonstrated some of their power management solutions (where they are trying to integrate more functionality in order to reduce BOM cost of the system) and advances in the audio codec lineup.
