About
Canaan Ng’s research sits at the critical intersection of haptics, human-robot interaction, and surgical robotics, with a focus on making teleoperated systems more intuitive and effective for clinicians. His most cited work, “Performance evaluation of haptic hand‑controllers in a robot‑assisted surgical system” (2015, 56 citations), provides a foundational benchmark by experimentally comparing three commercial haptic devices. In this study, two surgeons and seven engineers performed peg-in-hole tasks of varying difficulty, revealing key trade-offs between controller fidelity and user performance—a contribution that has guided subsequent interface design in robot-assisted surgery. Ng further advanced the field with his 2017 paper on stiffness perception during pinching and dissection using teleoperated haptic forceps, where he addressed the specific challenge of providing realistic haptic feedback for bipolar forceps—a tool essential in neurosurgery. By identifying the limitations of current haptic hand controllers in conveying tissue stiffness, this work highlights the gap between available technology and clinical needs. Together, Ng’s research not only quantifies the usability of existing haptic systems but also charts a clear path toward more immersive, safer surgical interfaces.
