A New Softness Display Interface by Dynamic Fingertip Contact Area Control
نویسندگان
چکیده
A new softness display system has been developed which controls the fingertip contact area dynamically according to the detected contact force, based on the human softness recognition mechanism. The relative softness cognitive rate of four levels softness using the developed system was 98 percent while ten volunteers touched the device actively. The absolute softness cognitive rate, the rate of correct answer while the displayed softness was compared to the real objects, was 85 percent. The relative and absolute cognitive rates in “passive touch” were 94 and 75 percent respectively. It was demonstrated experimentally that the softness display is feasible by controlling the relationship between the contact force and the contact area at fingertip.

Cooperative arms are two or more arms in series which assume the structure of a parallel robot on account of gripping an intermediary object, and are commonly used in accurate assembly industries, coaxialization, movement of object, etc. Gripping an intermediary object is one of the complicated subjects in analysis of cooperative arms, whose analysis is mostly dependent upon the manner the obje...
متن کاملRobotic Grasping and Fine Manipulation Using Soft Fingertip
The ability to create stable, encompassing grasps with subsets of fingers is greatly increased by using soft fingertips that deform during contact and apply a larger space of frictional forces and moments than their rigid counterparts. This is true not only for human grasping, but also for robotic hands using fingertips made of soft materials. The superiority of deformable human fingertips as c...
متن کاملA novel tactile softness display for minimally invasive surgery
The use of Minimally Invasive Surgery (MIS) in various types of surgical procedures has increased significantly in recent years. However, its scope is limited due mainly to the fact that this procedure does not currently provide tactile feedback without which the surgeon can neither feel nor palpate tissue. In this paper, we describe a new tactile display that reproduces these missing constitue...

We present Ghostfinger, a technology for highly dynamic up/down fingertip haptics and control. The overall user experience offered by the technology can be described as that of tangibly and audibly interacting with a small hologram. More specifically, Ghostfinger implements automatic visualization of the dynamic instantiation/parametrization of algorithmic primitives that together determine the...
