Abstract

Background

Haptic feedback plays a crucial role in virtual reality (VR) interaction, helping to improve the precision of user operation and enhancing the immersion of the user experience. Instrumental haptic feedback in virtual environments is primarily realized using grounded force or vibration feedback devices. However, improvements are required in terms of the active space and feedback realism.

Methods

We propose a lightweight and flexible haptic feedback glove that can haptically render objects in VR environments via kinesthetic and vibration feedback, thereby enabling users to enjoy a rich virtual piano-playing experience. The kinesthetic feedback of the glove relies on a cable-pulling mechanism that rotates the mechanism and pulls the two cables connected to it, thereby changing the amount of force generated to simulate the hardness or softness of the object. Vibration feedback is provided by small vibration motors embedded in the bottom of the fingertips of the glove. We designed a piano-playing scenario in the virtual environment and conducted user tests. The evaluation metrics were clarity, realism, enjoyment, and satisfaction.

Results

A total of 14 subjects participated in the test, and the results showed that our proposed glove scored significantly higher on the four evaluation metrics than the no-feedback and vibration feedback methods.
