Multi-mode Simultaneous Tactile Feedback Using Soft Pneumatic Fingertip Actuator with Dual Air Chamber

The paper suggests a new fingertip actuator made of silicone that can simultaneously produce pressure and vibrotactile feedback in order to offer a more realistic and immersive haptic experience in virtual environments. The actuator has a dual-layer air chamber design, with the top layer providing vibration feedback and the bottom layer providing pressure feedback. Pneumatic valves with pressurized air tanks can regulate the actuator. The actuator was tested in a simulated environment to render three different kinds of haptic textures. It is made to be worn conveniently at the fingertips. To compare the effectiveness of the suggested actuator to an actuator with a single vibrotactile feedback, performance assessments and user studies were done.
