Abstract: The spatiotemporal consistency of multi-modal haptic and immersive visual feedback, as well as the integration of hardware devices in the existing VR software framework, restricts the rapid development of visuo-haptic fusion scenarios in different industries such as medical, business, and entertainment. In order to tackle this problem, an adaptable VR software framework combining multi-modal haptic and immersive visual display is proposed. To meet the different requirements of visual rendering, haptic rendering and hardware control, the double-layer and three-layer architectures are devised according to the different precision requirements of visuo-haptic fusion feedback. Experimental results show that the framework has the characteristics of supporting the synchronous feedback of visuo-haptic fusion, the convenient integration of diverse haptic devices, the simplicity of scene development and the rapid replacement of interactive scene, and it can meet the requirements of different application fields.

Key words: virtual reality, multi-modal haptic, human-machine interaction, visuo-haptic fusion, adaptable software framework
