Windows7 touch screen for an extra 100 dollars?

&http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; Multi-Touch Technology (Multitouch), which allows users to enter multiple locations on the screen at the same time, is a completely different way of man-machine interaction than the traditional mouse-keyboard input. The most striking feature of this technique is that multiple users can interact with the machine at the same time, each user can use more than one finger to operate the screen, more importantly, the system can also identify the gesture of the finger, such as the use of two fingers to scale an image, with a finger moving objects, can also produce pinch effect.

The current implementation of Multitouch is mainly based on two technologies: Infrared projector and IR camera, and surface array led. The previous method used more, but also more mature, it is based on a technology called frustrated total Internal Reflection (FTIR), the camera collects the finger on the underside of the infrared scattering light image processing, analysis of the position and posture of the finger, The computer can then respond accordingly.

Touch technology is one of Windows 7 's bright spots, and Microsoft is showing the first feature of Windows 7, but in fact, touch technology may be just a device. Many in the industry said that October 22 windows 7 after the listing, not how many users to use the feature, Because the display cost of supporting the touch technology is 100 dollars higher, this will undoubtedly increase the cost of PC.

As a result, there will not be a few desktops and notebooks on the market that support Windows 7 touch technology. According to Richard Shim, a Richard Sim analyst, the touchscreen PC will have a market share of only 5% to 10% by 2010.

Moreover, in the next few years, the market share will not be a significant increase. In fact, for computers, the use of finger on the screen touch operation is not a "killer application", and mobile phone using touch screen is completely different.
