Abstract
Compared to the study on tactile feedback gloves, the kinesthetic feedback device, which has been studied for the past several decades, has difficulties in interacting with the user owing to various problems, such as large size, low portability, and high power consumption. Herein, we present a bidirectional finger kinesthetic feedback device that can provide an immersive virtual reality experience using a shape memory alloy (SMA). The proposed device provides kinesthetic feedback without heterogeneity by integrating efficient power control of the SMA actuator, fast cooling of the SMA within one second, and high-precision motion-tracking technology. The implemented device delivers a gripping and hand spreading force of up to 10N each to the index and middle fingers.
