Touch-Control Electronic Device With Reset Report Packets

The patent segments the continuous touch operation into distinct phases by detecting contact area changes. When the contact area transitions from small (finger) to large (palm) and back to small (finger), the system generates separate report packets for each phase, treating it as multiple discrete operations rather than one continuous operation. This segmentation resolves the contradiction by maintaining operational simplicity while preventing false operations through proper phase differentiation.

The patent applies preliminary action by proactively generating reset report packets when contact area thresholds are crossed. Instead of waiting for the operation to complete and then processing it, the system detects threshold transitions in advance and generates appropriate report packets during the transition phases. This preliminary detection and reporting mechanism prevents false commands from being generated while maintaining relatively simple processing logic.

The patent uses parameter changes by monitoring contact area size as the key differentiating parameter between finger and palm touches. The control chip compares real-time contact area measurements against predefined thresholds to identify touch types. This approach improves touch type identification accuracy while keeping the control chip relatively simple, as it only requires basic comparison logic rather than complex analysis algorithms.
