With advancements in mobile computing and virtual/augmented reality technologies, wearable haptic devices have the potential to enhance information delivery channels. This study addresses the challenges of designing an effective wearable haptic device by considering both ergonomics and haptic performance. The use of multilayered dielectric elastomer actuators, a lumped-parameter model of the skin, and a wearable frame helps achieve effective force transmission and low profile design.
With advances in mobile computing and virtual/augmented reality technologies, communicating through touch using wearable haptic devices is poised to enrich and augment current information delivery channels that typically rely on sight and hearing. To realize a wearable haptic device capable of effective data communication, both ergonomics and haptic performance (i.e., array size, bandwidth, and perception accuracy) are essential considerations. However, these goals often involve challenging and conflicting requirements. We present an integrated approach to address these conflicts, which includes incorporating multilayered dielectric elastomer actuators, a lumped-parameter model of the skin, and a wearable frame in the design loop. An antagonistic arrangement-consisting of an actuator deforming the skin-was used to achieve effective force transmission while maintaining a low profile, and the effect of the wearable frame and structure was investigated through lumped-model analysis and human perception studies.
