Immersion, interaction, and imagination are three features of virtual reality (VR). Existing VR systems possess fairly realistic visual and auditory feedbacks, and however, are poor with haptic feedback, by means of which human can perceive the physical world via abundant haptic properties. Haptic display is an interface aiming to enable bilateral signal communications between human and computer, and thus to greatly enhance the immersion and interaction of VR systems. This paper surveys the paradigm shift of haptic display occurred in the past 30 years, which is classified into three stages, including desktop haptics, surface haptics, and wearable haptics. The driving forces, key technologies and typical applications in each stage are critically reviewed. Toward the future high-fidelity VR interaction, research challenges are highlighted concerning handheld haptic device, multimodal haptic device, and high fidelity haptic rendering. In the end, the importance of understanding human haptic perception for designing effective haptic devices is addressed.

Multisensory lab based in Peking University,has carried out basic studies in multisensory space and time processing,intersensory binding and haptic/tactile perception.We exploited a typical paradigm of multisensory illusion-temporal ventriloquist effect and applied it in a wide range of multisensory interactions(mainly focused on temporal processing).In this work,we summarized how the tactile stimuli were exploited to compose tactile cues and as tactile apparent motion to interface with other sensory stimuli(visual and auditory stimuli)to examine the underlying perceptual organization in a multisensory context.Moreover,we introduced two examples of wearable haptic/tactile perception in our lab,by using two customized tactile devices and discussed the potential applications in this field.
