Method & Evidence

AimTo investigate the potential of a shape-changing, vibro-tactile fabric display for enhancing user interaction with 2.5D visual content.
MethodExperimental and Simulation
ProcedureThe researchers developed a tabletop display system (TableHop) using a stretchable spandex fabric with transparent electrodes. They used electrostatic actuation to control surface deformation (up to +/- 5 mm) and vibro-tactile feedback (up to 20 Hz). Simulations and experiments were conducted to analyze deformation shapes and vibration frequencies. A prototype was built and tested.
