AI Technical Summary
Technical Problem
Existing touch panel technologies inaccurately detect touch positions due to the non-planar nature of fingers, leading to errors when the moment of pressing and releasing differ, causing incorrect key selection.
Method used
A touch panel method that calculates the cumulative weight value of key areas touched during a continuous touch action and selects the key with the largest cumulative weight value to correct errors, using a keyboard interface with weighted regions.
Benefits of technology
Accurately determines the intended key by selecting the key with the largest cumulative weight value, thereby reducing errors in touch detection.

Abstract
A touch-sensitive key sensing error detection and correction method involves a touch panel displaying a keyboard interface. The keyboard interface has multiple key areas, each key area has multiple weight areas, and each weight area has a weight value. After sensing a touch action, the touch panel generates multiple sets of touch information. Each set of touch information includes a touch area value corresponding to the touched area at that time and a sensing area information corresponding to the touched area at that time. The touch panel determines the one with the largest touch area value in the set of touch information, calculates a cumulative weight value for each covered key area, and selects the key with the largest cumulative weight value among all covered key areas as the selected input key for the touch action, thereby avoiding errors.
