Wearable Range-Vibrotactile Field: Design and Evaluation
نویسندگان
چکیده
Touch is one of the most natural methods of navigation available to the blind. In this paper, we propose a method to enhance a person's use of touch by placing range sensors coupled with vibrators throughout their body. This would allow them to be able to feel objects and obstacles in close proximity to them, without having to physically touch them. In order to make effective use of this vibrotactile approach, it is necessary to discern the perceptual abilities of a person wearing small vibrators on different parts of their body. To do this, we designed a shirt with small vibrators placed on the wrists, elbows, and shoulders, and ran an efficient staircase PEST algorithm to determine their sensitivities on those parts of their body.

Touch, Movement and Vibration: User Perception of Vibrotactile Feedback for Touch and Mid-Air Gestures
Designing appropriate feedback for gesture interfaces is an important aspect of user experience and performance. We conduct the first investigation of users’ perceptions of vibrotactile stimuli during touch and mid-air gesture input for smart devices. Furthermore, we explore perception of feedback that is decoupled from the smart device and delivered outside its operating range by an accessory ...

متن کاملEnhanced Design of a Soft Thin-Film Vibrotactile Actuator Based on PVC Gel
We fabricated a soft thin-film vibrotactile actuator, which can be easily inserted into wearable devices, based on an electroactive PVC gel. One of the most important factors in fabricating a soft and thin vibrotactile actuator is to create vibrational force strong enough to stimulate human skin in a wide frequency range. To achieve this, we investigate the working principle of the PVC gel and ...
