Improving human‘s spatial information perception in virtual reality through distributed haptic stimulation

Uncertain and insufficient spatial information transfer is a problem with current virtual reality interactions, particularly for those who are hard of hearing and have trouble identifying sound sources. To enhance the interaction experience and foster the inclusive development of virtual reality technology, this article seeks to establish a theoretical design framework for wearable devices that facilitate the transfer of spatial information in virtual reality. First, the article analyzes interaction scenarios in virtual reality to identify the types of spatial data that need to be communicated through haptic feedback. Next, the relevant information is categorized by location, characteristics, and layers, forming the basis for design objectives and evaluation criteria. Finally, suitable haptic feedback methods and stimulation sites are selected, and both hardware and software are developed.
