Abstract In this research, we proposed a new display with a dynamically changeable softness parameter called ”ClaytricSurface”. While conventional displays generally have fixed softness, we focused on interactive displays with a controllable softness property. We developed a prototype system by...

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...

We present SoftAR, a novel spatial augmented reality (AR) technique based on a pseudo-haptics mechanism in the human brain that visually manipulates the sense of softness perceived by a user pushing a soft physical object. Considering the limitations of projectionbased approaches that change only the surface appearance of a physical object, we propose two projection visual effects, i.e., surfac...

Softness perception intrinsically relies on haptic information. However, through everyday experiences we learn correspondences between felt softness and the visual effects of exploratory movements that are executed to feel softness. Here, we studied how visual and haptic information is integrated to assess the softness of deformable objects. Participants discriminated between the softness of tw...

One of the major disadvantages of the minimally invasive surgery (MIS) is the lack of tactile feedback to the surgeon. In order to identify and avoid any damage to the grasped complex tissue by endoscopic graspers, it is important to measure the local softness of tissue during MIS. One way to display the measured softness to the surgeon is a graphical method. In this paper, a new tactile sensor...

Softness is one of the most important properties for an apparel fabric. This paper investigated the feasibility of objective evaluation of fabric softness by measuring the forces of pulling a fabric specimen through a series of parallel pins. The specific pulling forces of fabric specimens were compared with those indexes obtained both from FAST (Fabric Assurance By Simple Testing) tests and su...

This paper develops a multi-fingered robot hand with skin mechanism enabling softness change. We show how the softness of the skin affects grasping and manipulation. Elastic skin provides stable grasping while precise manipulation is lost. Hard skin provides precise manipulation while stability of grasp is lost. We will try to change the softness of the skin according to situation, object, and ...

A series of microgel particles composed of a polystyrene (PS) core and a thermo-sensitive poly(N-isopropylacrylamide) (PNIPAM) shell with different shell thicknesses were investigated to elucidate the effect of microgel softness on its shear thickening behavior. Since the softness of the microgels increases with decreasing temperature through the volume phase transition effect of PNIPAM shell, ...

We report a novel method to prepare soft colloids with well-controlled softness. The softness of the colloids was characterised by atomic force microscopy and rheometry. Possible applications of such soft colloids in uniform particle coatings are demonstrated.
