Wave Focusing in Metamaterials: Tactile Displays Beyond the Diffraction Limit
Gregory Reardon, Max Linnander, Dustin Goetz +2
We address the challenge of engineering distributed haptic displays capable of reproducing multiple localized, independently addressable vibrations -- representing virtual tactile…
Thermopneumatic Pixels: Fast, Localized, Robust, Low-Voltage Touch Feedback
Max Linnander, Yon Visell
We present thermopneumatic pixels (TPPs) -- low-profile pixels and arrays that generate dynamic tactile feedback. These devices are thin, fast, reconfigurable, and output localized…
Haptic Light-Emitting Diodes: Miniature, Luminous Tactile Actuators
Max Linnander, Yon Visell
We present Haptic Light-Emitting Diodes (HLEDs), luminous thermopneumatic actuators that directly convert pulsed light into mechanical forces and displacements. Each device package…
Tactile Displays Driven by Projected Light
Max Linnander, Dustin Goetz, Gregory Reardon +3
Tactile displays that lend tangible form to digital content could transform computing interactions. However, achieving the resolution, speed, and dynamic range needed for perceptua…
