Recognizing the working mechanism of the proposed VRTD, a visually impaired user also can benefit from the device. The device can deliver the input characters to the tip of finger if coded as the Braille rule so that the user can read out his input as soon as the

Figure 23.16 Virtual reality tactile display system.

Wearability To generate the virtual reality of tactile feel, we should move our hand actively and freely, and receive appropriate stimuli in response to the hand movements. An IPMC based wearable display was successfully developed, which was made so small in size and weight that there was no interference with hand movements [8],... 

Tactile sensation is the most widely spread sensory function in the human body, so it is an essential part of the human perception mechanism. Complete or successful realization of the tactile function may place a cornerstone in the fields of robotics, virtual reality, medical engineering and so on. A tactile display is one of the most important communication devices and it conveys intellectual information in the form of skin stimulation. Although the graphical or visual device has been a typical form of the modern information transferring tool, the role of the tactile display has been extended to various applications, such as attaining reality in video games or guaranteeing accuracy in telemanipulation [1—4]. Especially, it has been a critical means for communication for the visually handicapped.
