Pattern recognition algorithms integrated into the technology can offer finer motor control than an amputee could ever dream of, including a "
pinch grasp" with the thumb and index finger to hold a pencil; a "three-finger grasp" to grab a bottlecap or piece of candy; a generic "power grasp" to shake hands or hold a bottle; a "tool grasp" that lags the index finger behind to grip a drill; and a" key grasp" to hold ...
They are represented by

(10) Complete tears repaired after 3 weeks tend to have an increased incidence of weakness and pain on
pinch grasp. For this reason, early surgical intervention is generally undertaken for all cases of ruptured ulnar collateral ligaments.
Topics include the effect of cognitive load on tactor location identification in zero-g, a bow spring and tendon actuator for low-cost haptic interfaces, fundamental limits in the rendering of virtual haptic textures, real-time finite element finger
pinch grasp simulation, and a force feedback interface for cell injection.
