摘要： Disclosed is a “keyboard overlay” that sits on top of a touch-sensitive display screen of a computing device. After aligning the overlay on the display screen, the user types on the overlay. When the user presses a key on the overlay, the pressure is transmitted to the display screen below. That pressure is registered by the display screen as a touch. The keyboard overlay is formed to provide tactile finger-position feedback so that a user can keep his fingers oriented properly over the keyboard. The overlay may be opaque with keycap information displayed in the key areas. The overlay may be transparent, allowing a user to see a virtual keyboard painted on the display screen below. The computing device can detect the presence and type of an overlay. Applications may respond differently to different types of overlays. Different applications may be invoked depending upon the type of overlay detected.

摘要： Disclosed are a method and a system for detecting multiple, simultaneous touches on a touch-sensitive screen of a computing device. The hardware that controls the touch screen performs two measurements to locate a touch location on the screen. If there is a single touch, then the two measurements are equal. A non-zero difference indicates multiple touches and is correlated with the spread of locations simultaneously touched on the screen. If the difference is greater than a set threshold, then an indication is given of multiple touches. The user is warned against multiple touches, and input from the screen is ignored as long as multiple touches are detected. For some embodiments, when multiple touches are detected, the invention also tries to indicate the boundary of the set of locations simultaneously touched. The boundary is used to interpolate the intended single touch from the locations of all the touches.
