A laser-based haptics system lets you feel distant objects
Hiroaki Yano, associate professor in the department of intelligent interaction technologies at the University of Tsukuba, Japan, is working on a handheld haptic device for sensing unreachable or untouchable objects. The prototype system employs a laser range finder to determine the distance to a given object. The data are fed to a computer, where an algorithm calculates the motor torque necessary to move a lever backward and forward in real time on a haptic interface device; the degree of movement corresponds to the changing distance the laser beam measures as it tracks across the surface of the object. By pressing a thumb against the moving lever, the user can feel the reaction force generated by the object and so get a sense of its shape, even down to changes in surface depth as fine as 0.1 millimeter. The device works for a distance up to 1 meter and through glass.

A motor-studded haptics Jacket Lets You Feel the Movies
Researchers from Philips Electronics plan to describe a jacket they have lined with vibration motors to study the effects of touch on a movie viewer’s emotional response to what the characters are experiencing.  The jacket contains 64 independently controlled actuators distributed across the arms and torso. The actuators are arrayed in 16 groups of four and linked along a serial bus; each group shares a microprocessor. The actuators draw so little current that the jacket could operate for an hour on its two AA batteries even if the system was continuously driving 20 of the motors simultaneously.
