Haptic Interfacing

Haptic-VR Synchronization

Haptic interfacing aims to integrate the MR haptic module with a VR environment to enable realistic, resistance-driven tactile feedback. The figure illustrates a diagram of the haptic interface and potential future applications for airplane cockpit interactions

Progress Made

An Arduino-based control system was developed to transmit real-time angular position data from the rotary encoder to Unity. A C# script then synchronizes the virtual dial’s rotation with the physical dial, ensuring precise input mirroring. A visual indicator at the base of the virtual dial confirms that its motion aligns with the physical dial’s rotation.

Future Work

Characterize the torque output of the MR dial prototype using audio signals
Integrate haptic modules into real-world applications, such as pilot and surgical training
Evaluate audio-haptic applications through human testing
