Vibration-based wearable haptic feedback device and its applications

Abstract

Vibrotactile feedback technology can convey a variety of information by adjusting the duration, frequency and intensity of vibration, thereby improving user perception, enhancing user experience, providing reminders and notifications, realising accessible applications and meeting the needs of diverse application scenarios. This paper first describes the principle of vibrotactile feedback, and explains in depth how the human tactile sensory system can simulate different tactile sensations. Next, the article explores wearable device materials that can help with better vibration perception and more comfortable motion fit, as well as the evolution and improvement of different types of haptic feedback devices. Finally, application scenarios of vibro-haptic feedback devices in healthcare and education are presented, such as exercising patients muscles and helping students learn better through immersive learning through vibro-haptic feedback device models. The research in this paper has an important reference value for the future research and application of human-computer interaction sensors, and we believe that vibrotactile feedback devices will be more widely used and promoted in the future.
