Abstract
Tactile displays don’t disturb other people and transfer the information secretly by directly contacting with person’s body. Tactile letter recognition means that the users recognize the ordinary language conveyed on the skin surface. We propose stimulus presentation of drawing type for tactile letter recognition. It is the type that is drawing the line directly to the skin with a pen instead of dot stimulus of array type. We built the prototype of drawing type device. The tracing mode was a good at recognition rate of the letters averagely than static mode in tactile letter recognition. But it was still hard to recognize special letters having same number of stroke or similar stroke style, because touch sensory is dull of localization and perception of stimulus. To improve recognition rate of confused letters, we redesigns stroke patterns to a new sequence pattern having less stroke number and unique pattern.
