Abstract

An active feedback interface for a touch screen display that includes the display of visual cues (710) to indicate when and where the display is touched by a user. The visual cue (710) may change over a period of time depending on the particular active or inactive area of ​​the touch screen contacted by the user's finger.

Description

technical field [0001] The subject matter of this specification relates to systems and methods for improving a user's touchscreen precision by providing active user feedback. More specifically, the systems and methods described herein provide visual cues to the user to indicate when and where the display is touched. Background technique [0002] Touch displays that respond to localized touch contacts are known. The device includes a resistive sheet in which a uniform orthogonal electric field is generated. The location of a touch is determinable when a low resistance or ground connection is established by the touch at a particular location on the screen. The device is used to generate a virtual key such that when touched, the virtual key is activated to perform a preprogrammed operation. [0003] Known touch screens are used in many applications including handheld mobile devices, automobiles, airplanes, and the like. More recently, the touch display has found application...
