The invention is in use for providing device and method of
graphics text information for crowd of
visual disturbance. In the device, mouse, keyboard or pick-up head through series-parallel ports or
USB port are connected to computer. Through mouse, keyboard or pick-up head, operator selects expectant
graphics text. Through series-parallel ports or
USB port,
signal of
graphics text output from computer is connected to a haptic stimulus device of
jet flow. Through control cable, output
signal of the haptic stimulus device of
jet flow is connected to
haptic display of
jet flow. Finally, information of graphics text in haptic mode of jet flow acts on
skin surface of operator. The operator obtains knowledge and haptic
cognition about surrounding environment. Using confluent characters of pressure-temperature of jet flow stimulus, the invention can provide
haptic display of heat
sensation or information of
color graphics text.
