Haptic Force-Cepx
This project explores force-feedback interface design for more intuitive human-robot interaction. The focus is on translating sensed force signals into clear, stable haptic cues that improve operator confidence and precision.
Project Goal
Design and evaluate a haptic interaction prototype that can communicate environmental resistance and contact events, reducing user uncertainty during teleoperation or guidance tasks.
What I Did / My Contribution
- Designed interaction scenarios and key feedback requirements for user tasks.
- Integrated sensing and actuation loops for responsive force-feedback behavior.
- Tested and refined signal filtering to reduce jitter and improve feedback quality.
- Recorded observations on usability and interface clarity for future design iterations.
Methods / Workflow
- Define target interaction use cases and measurable usability criteria.
- Build force input-output mapping and baseline control logic.
- Run calibration and sensitivity tests under different interaction conditions.
- Iterate hardware/software parameters using feedback from trial sessions.
