How Many Touch Points Does Windows 7 Multi-Touch Support?

As above. I think I heard it supports either a very high number (e.g. 5000) or unlimited - obviously restricted to the开发者_开发问答 device.

The Microsoft Surface v2.0 Hardware + Software platform was introduced in early January at CES. During the demo, they demonstrated it detecting 20 simultaneous touch points. I don't know if the surface itself (screen, not the "Surface" device) can detect/support more. Also, 3M's M2256PW monitor also supports up to 20 touch points.

If you install the MultiTouchVista emulator driver, Windows does report it as having 255 touch points (mice), which may be a hard number set in the MTV code, and not Windows.

Basically, I would surmise that the number of points supported is likely higher than either

• The number of points the hardware can detect
• The total number of points you could fit on just about any hardware in regards to people around it
