The Impact of Simultaneously Applying Normal Stress and Vibrotactile Stimulation for Feedback of Exteroceptive Information

Abstract: Commercially available prosthetic hands do not convey any tactile information, forcing amputees to rely solely on visual attention. A promising solution to this problem is haptics, which could lead to new prostheses in which tactile information is conveyed between the amputee and the artificial limb. However, the haptic feedback must be optimized so that amputees can use it effectively; and although several studies have examined how specific haptic feedback systems can transmit certain types of tactile informa… Show more

“…Human skin can perceive multimode stimuli at the same time. [76][77][78][79][80][81] Thus, different stimulation modes can be combined or organized in particular order to provide enriched sensation from skin. For instance, in a prosthesis system with both mechanotactile and electrotactile stimulation for grasping feedback, the mechanotactile mode can be used to indicate touch with a normal object, while the electrotactile stimulation can be executed when touching sharp objects or a cup of hot beverages, as the rather uncomfortable tingles will keep the prosthesis wearer alert for safety, and can be avoided during nonhazardous grasping tasks for comfort.…”

“…It can mimic tactile sensations when the skin is pressed or stretched. The mechanotactile stimulation can provide sufficient sensory information for object identification [108,123,124] or grasp control [87,123,125,126]. On the other hand, the miniaturization and integration of mechanotactile stimulation are challenging.…”

“…To this end, Premarathna et al presented a soft tactile display that produces force and vibration feedback using a pneumatic balloon and electromagnetic coil [18]. A haptic device was also designed to show the impact of simultaneously applying normal stress and vibrotactile stimulation [19]. They used a piston with a DC motor to apply normal force to the skin and two shaftless cylindrical vibrator motors to generate vibrotactile stimulus.…”
