About

Tzvi Ganel is a leading researcher in the intersection of human perception, action, and robotic systems, with a particular focus on visually-guided grasping and teleoperation. His work fundamentally challenges classical psychophysical models by demonstrating that while natural, direct grasping violates Weber’s law—suggesting a distinct visuomotor system—remote and virtual environments cause grasping to revert to perception-based, Weberian behavior. This key insight, published in his highly cited 2018 paper on human-centered transparency in robot-assisted minimally invasive surgery (RAMIS), has profound implications for surgical robotics and telerobotic design. Ganel’s research reveals that transmission delays, scaling of grippers, and the loss of haptic feedback degrade the natural action system, forcing the brain to rely on slower, perceptual processing. By defining “human-centered transparency” as a metric for how naturally a human can act through a robotic interface, he provides an objective framework for evaluating and improving teleoperation systems. With over 70 citations across his most influential works, Ganel’s contributions bridge experimental psychology and engineering, offering critical guidance for designing more intuitive, effective remote manipulation tools in surgery and virtual environments.
