For a long time, the sense of touch has been regarded as an inferior sense as compared to vision or audition. However, the potential to receive information through touch is well illustrated by natural communication methods used by individuals with severe auditory and/or visual impairments. The last decade has witnessed renewed interests in transmitting information through touch for enhanced interaction experience. I will start this research overview talk will a brief introduction to the human somatosensory system. I will then present an overview of state‐of‐the‐art haptic technologies. Finally, I will discuss two research programs, haptic cuing of visual attention and visuohaptic watermarking, to illustrate the application of haptics in multimodal user interfaces.
