In a haptic shape task, the human ability to discriminate objects on basis of their shape, as defined by active exploratory movements of the hand, is dependent on receptors located in the skin and deep structures. The shape of a 2-d object is a function of its geometric properties, including the pattern of the surfaces that form the object, their density, their size, and their spatial features. It is now widely known that haptic shape task shares neural activity in visual cortical areas, but we have little information about the factors for haptic shape perception. We investigated to what factors of pattern play an important role in a haptic shape discrimination task. Haptic shape can be gained through a small braille device. There are 10 baselines in the experiment, and 6 kinds of other patterns based on each baseline were made. Healthy right-handed subjects performed a delayed-match-to sample task discriminating between pairs of two-dimensional patterns. From the different characteristics of difficulty in the pattern task, we concluded that different difficulty in discrimination task are underling haptic shape patterns with different densities and sizes.

Although previous studies have demonstrated visual processing in detection and discrimination task in human, how detection and discrimination task alter visual processing has not yet been completely elucidated. To investigate this issue, we design performing two classical perceptual tasks: 1) grating detection experiment, 2) grating orientation discrimination experiment. In grating detection experiment, participants were instructed to identify stimulus, if they saw a stimulus, by pressing right button as quickly and accurately as possible. In grating orientation discrimination experiment, participants were told to identify the orientation of the stimulus and pressed relevant button as quickly and accurately as possible. We assessed the diversity by measuring the magnitude of sensitivity and intercepts through reaction times (RT). The results showed that RT strongly depended on experimental task. The response to discrimination task is significantly slower than that for detection task (p &lt
0.05). However, visual detectability was not depended on experimental task, and no significant difference of sensitivity was found among detection task and discrimination task (p &gt
0.05). Our results provide unique insight into how the brain processes visual signal of different experimental task, and will provide some basic data for human-robot signal processing.

Recently, virtual reality (VR) have received increasing attention. For the development of VR, human recognition mechanism is a crucial factor. Previous neuroimaging studies of the visual recognition have found that mechanism of recognition is different on retinal eccentricity of visual field. For example, when we recognize the face, the building and the scene, we use the central vision field. However not only the central vision field but also the peripheral vision field is used for building recognition. And for the recognize of the scene, the peripheral vision field is even more important than central vision field. Revealing the object recognition mechanism demands us to clarify the functions of the central and the peripheral vision field. The purpose of this study is the first step to reveal the object recognition mechanism of the central and the peripheral vision field. We analyze the dependency of the fundamental elements of the objects on retinal eccentricity. The retinal eccentricity is the degree of the gap between the central and the peripheral vision field. Basically, we measured the dependency of recognition on retinal eccentricity of visual field as we changed the elements and the exposure duration of stimuli. The fundamental elements of the objects are the stimuli size and the line width of the stimuli. The stimuli size and the line width of the stimuli showed a large dependency on retinal eccentricity of visual field. But the exposure duration of stimuli showed a small dependency on retinal eccentricity of visual field.
