Windows 7: Touch screen in W7?

Touch screen in W7?

Although Iím not using Windows 7 OS yet, what it has to offer & all that Iíve seen, it's pretty impressive. I'm in the process of deciding whether to go with the upgrade Windows 7 or purchase a new Laptop/Notebook? One concern or complain I must state. I understand that Windows 7 comes with touch screen capabilities, but ONLY works with a human touch? Being physically disabled & cannot use my hands at all I type by using a head-pointer with an eraser for a tip. Yes, Iím not going to be dishonest here, Iím using an aftermarket touch screen with Vista, but Iím leery on how (or if) I can still use it with Windows 7? I donít know how, but I would just love to get in contact with a MS Developer to express my views. Am I correct in assuming that the touch screen option requires a human finger touch?

Windows 7 isn't limited to touchscreens that only respond to finger operation but to touchscreens whose controllers identify them as HID touch devices, a relatively new category. Windows 7, like its predecessors, recognizes HID mouse devices, which most touchscreens have been until recently. Treating a touchscreen as a mouse has never delivered the best user experience, as it precludes right-click-on-hold, calibration, edge acceleration, and many other valuable facilities. Consequently, vendor-specific drivers, which do provide these facilities, have been used. Windows 7 accepts most of these drivers. In the WDM driver stack, these are lower-level drivers. To the OS, the device still appears to be mouse. Therefore, none of the new touchscreen-specific features of Windows 7 will be available.

The reason that you might have heard that only finger operation is supported is that Windows 7 recognizes as touch devices only those that identify themselves as HID-touch. Of these, only the ones that generate touch-specific events allow you to use gestures and multi-touch. The two technologies most likely to support these are capacitive, which requires finger activation, and wire-matrix digitizer, which requires an electronic pen. Windows 7 can still use other touchscreens, including old ones, but the new capabilities will not be available.

Sir,

Here's my question, Right now I have an aftermarket touch screen over my laptop screen , which I already stated I use a head pointer with an eraser as a tip to type with & operate my touchscreen (no mouse useage). What I'm trying to deternmine is with Windows 7, will i be able to do away with my aftermarket Touchscreen & work right off of Windows 7 Touchscreen?

Thanks

No. Windows 7 cannot turn an ordinary display into a touchscreen. Most touchscreens used on computers consist of a glass and/or plastic plate placed on top of the display screen. Without this hardware, there is no means of detecting touch.

What brand is the touchscreen you're using? I have a Hoda touchscreen on my netbook and the default windows drivers work for it.

They have drivers up to vista, I think it'll work with little issues withou drivers. If it doesn't the vista or xp drivers should get you set up.
