摘要：Portable electronic devices have been designed to perform a large variety of functions, including cellular phone, personal digital assistants (PDAs), video camcorders, digital cameras, and nootbook computers. All of these devices store information and perform tasks under direction of the user of the device, and therefore have a user interface.Many pen-based devices, such as personal digital assistants (PDAs), mobile phone-PDA hybrids, and ultra mobile personal computers (UMPCs) utilize sensing technologies that can track not only a stylus, but also touch input. This makes touch input an option when pen input is not possible, such as one-handed operation. However, so me user interfaces o ften contain small dense targets.A finger Shift is a tech nique to tackle the problems with using finger touch. It offset the screen content to avoid ll three drawbacks of Offset Cursor then leads to significantly better performance. A touchscreen is an input device normally layered on the top of an electronic visual display of an information processing system. A user can give input or control the information processing system through simple or multi-touch gestures by touching the screen with a special stylus/pen and-or one or more fingers. Typically, a touch-screen display is electrically coupled to a computer. It generates images to be sho wn on the display
