Prototype Laser System Lets sers Feel Remote Objects
Researchers say the laser-based haptic feedback system could be used to educate viewers about valuable exhibits and to inspect engineering products.

The haptics feedback technology on touchscreen phones uses vibrating pulses to replace the tactility of, for example, pressing a physical button. At the recent computer graphics event SIGGRAPH Asia 2009, a team of researchers from the University of Tsukuba demonstrated what they can do with haptics by letting users "feel" a remote object.
The prototype system comprises a laser range finder, computer and haptics generator. By placing the device on a glass casing and using the laser to measure the distance from the panel to the actual object, the user can "feel" the latter via the pulses that are generated.
According to the literature, the reaction force is determined by the distance between the handheld device and the actual object. Users supposedly can feel details such as texture when the magnification factor is increased. The researchers say the system can be used for educating viewers about valuable exhibits and for the inspection of engineering products.
