Touch Screen Accidental Input Prevention via Motion Sensor Verification

The patent introduces motion sensors (accelerometer, gyroscope) as intermediary devices that detect terminal motion state and provide additional verification layer between touch input and operation execution. The motion state information acts as a mediator to distinguish intentional touches from accidental ones by checking whether the terminal motion matches expected patterns for the touched application or function.

The system continuously monitors terminal motion state through sensors and provides feedback by comparing actual motion with expected motion patterns. When motion feedback indicates the terminal is being held steadily (no significant acceleration or rotation), the system confirms the touch is intentional. This closed-loop feedback mechanism prevents accidental operations while maintaining responsiveness to valid user inputs.

The motion sensors serve multiple functions: detecting terminal orientation, monitoring motion state for accidental touch prevention, and potentially supporting other features like step counting or fitness tracking. By making the sensors multi-functional, the patent justifies their inclusion despite increased complexity, as they provide value across multiple system functions rather than being dedicated solely to touch verification.

The system uses the terminal's existing motion sensors (accelerometer and gyroscope) that are already integrated into modern smartphones for other purposes. Rather than adding dedicated new hardware, the patent leverages existing sensor capabilities to serve the additional function of accidental touch prevention, thereby minimizing the actual increase in device complexity.
