Method and system for using a keyboard overlay with a touch-sensitive display screen
InactiveUS20050099403A1Fast typingPrecise positioningInput/output for user-computer interactionElectronic switchingTouch PerceptionVirtual keyboard
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.

An image processing apparatus determines whether or not a target pixel TP which is the object of the smoothing process is an edge-forming pixel based on the edge level (gradient g). If the pixel is determined to be an edge-forming pixel, the smoothing process employs an elliptical median filter instead of a moving average filter. The median filter MF has an elliptical reference area RA that is tilted (angled) to match the orientation of the edge Eg (edge angle), allowing the smoothing process to be carried out without compromising the edge components. The angle of the edge Eg is thus determined in the smoothing process, a median filter MF with an angle matching the determined edge angle is selected, and the selected median filter MF is used to carry out the smoothing process on target pixels TP which are edge-forming pixels.
