Abstract

The present invention relates to an electronic device with a touch-screen, which includes the touch-screen for receiving user input, a processor coupled to the touch-screen, a removable flexible material contacting the touch-screen, the flexible material having a plurality of key structures that modify a first touch applied by a user to a key structure of the plurality of key structures into a different, second touch applied to the touch-screen to generate a touch event, and a memory coupled to the processor and including computer code which when executed by the processor interprets the touch event generated by the second touch according to the first touch. A key structure may include physical structures that allow the user using the sense of touch alone to distinguish a key structure.

Description

technical field [0001] The invention relates to the field of portable consumer electronic devices, in particular to a software-assisted physical keyboard of a touch screen. Background technique [0002] Many new portable electronic devices use touch screens to receive user input. However, when users input text or phone numbers on the touch screen, they find it inconvenient to use the virtual keyboard on the screen. Regarding the accuracy of finger trigger positions on the virtual keyboard, users often trigger wrong keys due to lack of assistance and feedback from real objects, so some kind of software is needed to automatically correct input according to vocabulary characteristics. [0003] One existing solution is to add tactile technology to the touch-sensitive device to feed back force, vibration or movement to the user in response to the user's touch action on the touch screen. Since the tactile feedback is usually generated after the touch action is completed, it can ...
