The stimuli. (a) A PVC strip with smooth surface. It is the prototype shape in Experiment 1 and one of the real reference stimuli in Experiment 2. (b) A PVC strip with textured surface. It is the prototype shape in Experiment 1. (c) A texture model (Gratings are single sided copper on printed circuit boards). It is the prototype shape in Experiment 1 and one of the real reference stimuli in Experiment 2.

The finger skin contains a variety of receptors, which provide multiple tactile sensing channels. When a finger touches the surface of an object, people can simultaneously perceive curvature, texture, softness, temperature, and so on. However, in most of research activities, the designed haptic feedback devices can only focus on a certain channel....

Context 1
... stimuli were all synthesized shapes or textures rendered by the proposed system as described in Table 2 and Figure 5. In condition C, the stimuli were the simulated truncated circular profiles that had constant curvatures. ...
Context 2
... real models were used as reference stimuli. One was a smooth strip with curvature C = 20 m À1 and length L = 80 mm (see Fig. 5a). The other was a textured surface model with spatial period SP = 4 mm (see Fig. 5c). The test stimuli were the synthesized shapes with curvature only, curvature plus texture, texture only, and texture plus curvature, corresponding to condition C', CT', T', and TC', respectively. In conditions C' and CT', the test curvatures were 20 ± ...
