Haptics Engineering

The engineering of touch-based interfaces — vibrotactile feedback design, force-feedback actuators, texture rendering algorithms, thermal display systems, and electrostatic friction surfaces for next-generation human-computer interaction.

Haptics engineering bridges the gap between digital information and the human sense of touch. From the buzz of a smartphone notification to the resistance of a surgical robot's controls, haptic systems create tactile sensations that convey information, enhance immersion, and improve motor performance in ways that visual and auditory feedback alone cannot achieve.

These simulations let you design vibrotactile waveforms, tune force-feedback control loops, render virtual surface textures, model thermal display heat transfer, and explore electrostatic friction modulation — all with real-time visualization of the underlying physics and psychophysics.
