Force-Displacement Interaction Sensing for Reliable User Identification

The patent replaces traditional mechanical interaction methods (password typing, manual biometric scanning) with a mechanical sensor system that detects physical interactions. The sensor measures mechanical parameters (force, displacement, duration) of user interactions with the device surface, enabling rapid identification without manual input or complex biometric scanning procedures.

The patent changes the identification parameters from traditional methods (password strings, facial images, fingerprint patterns) to mechanical interaction parameters (force magnitude, displacement distance, interaction duration). These physical parameters are captured by the mechanical sensor and processed to identify users rapidly and reliably.

The patent creates a universal identification system that works across multiple conditions (different lighting, weather, user states) by detecting mechanical interactions that are inherently independent of environmental factors. The mechanical sensor detects physical actions (pushes, pulls, strokes) that can be performed reliably whether the user is wearing gloves, in dark conditions, or under various weather conditions, making the system universally applicable.

The patent uses simple, inexpensive mechanical interaction elements (such as buttons, switches, or surface sensors) that can be easily replaced or are inherently disposable. These simple mechanical components provide reliable identification without requiring expensive, complex biometric hardware that may fail under sub-optimal conditions.

The patent merges multiple simple mechanical interaction elements into a unified sensor system that captures comprehensive interaction data. By combining data from multiple simple sensors (force, displacement, duration measurements), the system achieves high measurement precision while maintaining the simplicity of mechanical interaction. The sensor array works together to provide detailed interaction characteristics from basic mechanical inputs.

The patent adds multiple measurement dimensions to simple mechanical interactions. Instead of detecting only basic button presses, the system measures force magnitude, displacement distance, interaction duration, and temporal patterns. By adding these dimensional parameters to simple mechanical actions, the system achieves high precision identification while keeping the interaction itself simple and intuitive.
