About

Naci Zafer is a researcher specializing in haptic interfaces, virtual reality, and robotic systems, with a particular focus on bridging the gap between physical and simulated environments. His work spans nearly two decades, encompassing haptic feedback for virtual assembly, constraint-based force and motion coupling between real and virtual mechanisms, and the biomechanical modeling of human-surface interaction. Among his most notable contributions is the development of a virtual manipulator concept that couples haptic device kinematics with simulated robotic constraints, enabling stable and intuitive control of six-degree-of-freedom systems. More recently, Zafer has advanced the field of soft-body haptics, introducing nonlinear viscoelastic contact models — including the Kelvin–Voigt fingertip framework — to realistically simulate the deformation of freeform surfaces and soft objects under frictional and compliant contact conditions. This work holds significant promise for surgical simulation, product design, and virtual prototyping. His research, while accumulating a modest citation footprint typical of specialized technical domains, reflects consistent originality across both foundational and applied challenges in haptics. Students and researchers working in teleoperation, virtual manufacturing, or human-robot interaction will find his body of work a thoughtful and technically rigorous foundation for exploring physically realistic haptic simulation.
