Abstract

Tactile device is used to display tactile data in image mode, which is normally received from a computer. In most cases, the original tactile picture is converted from the visual image, and it would be very convenient for saving and data conversion if tactile data was packaged in file format. In this paper, a file format is constructed for saving data in water-jet tactile, and a mapping algorithm is proposed between the RGB data in visual image and the physical stimulation factors in tactile image, including pressure, temperature and frequency. Experiments are designed to verify the validity of the algorithm, and results show that visual images can be transformed to the water-jet tactile image, can also be recovered from the tactile image correctly.
