متن کاملDesign and Performance of a Prototype Tactile Shape Display for Minimally Invasive Surgery
The design of a tactile shape display intended for Minimally Invasive Surgery (MIS) is presented. It consists of 32 micro brushless motors arranged in a 4-by-8 configuration, and the total size is 27 mm × 20 mm × 18 mm. The main restrictive design parameter is the size of the display as it will be attached to a laparoscopic grasper. Modularity is also crucial since it might be desirable to do e...
متن کاملHuman Tactile Spatial Sensitivity for Tactile Feedback
In this paper, we quantify several spatial capabilities of the hmnan tactile system needed for tactile feedback, or teletaction. Psychophysics experiments measure the amplitude resolution of the human tactile system, the effects of shear stress on grating orientation discrimination, and the effects of viscoelasticity {creep and relaxation) on tactile perception for static touch. The results are...
