Apparatus and method for touch screen interaction based on tactile feedback and pressure measurement

摘要

An apparatus includes a display section with a touch screen, and the touch screen is adapted to display at least one graphical user interface object and detect a touch position on the touch screen. The apparatus has a haptic feedback generating unit attached to the touch screen and is adapted to generating haptic feedback. A pressure sensing unit is attached to the touch screen and adapted to detect pressure applied to the touch screen. A controller section is adapted to control and drive the display section. The graphical user interface object displayed on the touch screen has a plurality of logical states. The controller section determines a current logical state of the graphical user interface object and a form of the haptic feedback to be generated depending on the detected touch position.
