Handheld Haptic Tool Capturing Surface Texture Models

The patent creates a digital copy of the surface's haptic properties by recording acceleration, force, and speed data during actual contact with the real surface. This haptic signature is then reproduced during virtual interactions, eliminating the need for manual tuning while maintaining authenticity. The system copies the genuine haptic characteristics directly from the physical surface rather than attempting to simulate them through complex parameter adjustment.

The patent replaces the manual tuning process with an automated data-driven system. Instead of mechanically adjusting haptic parameters to match authentic feedback, the system uses sensors to capture real haptic data and reproduces it through computational processing. This substitution of mechanical tuning with automated sensing and reproduction eliminates the complexity of manual adjustment while preserving feedback authenticity.

The patent merges multiple sensor types (accelerometers, force sensors, speed sensors) into a single integrated handheld tool. By combining these sensing functions in one device, the system achieves comprehensive haptic data collection without proportionally increasing operational complexity. The merged sensor suite works together to capture the complete haptic signature of surface interactions.

The handheld tool is designed as a multi-functional device that simultaneously performs acceleration measurement, force sensing, and speed detection. This universal tool can capture all necessary haptic parameters in a single interaction, eliminating the need for separate specialized devices and reducing overall system complexity despite the multiple sensing capabilities.
