A telerobotic test-bed has recently been built between KAIST(Korea) and Saga University(Japan). This paper presents its first research work on investigating the interactive learning performance of human teleoperators. For this purpose, the telerobotic test-bed was re-shaped to a telerobotic golf system. Eleven players were participated, and their interactive performance with the telerobot was c...

In the natural world, objects are characterized by a variety of attributes, including color and shape. The contributions of these two attributes to object recognition are typically studied independently of each other, yet they are likely to interact in natural tasks. Here we examine whether color and size (a component of shape) interact in a real three-dimensional (3D) object similarity task, u...

Retinal sampling poses a fundamental limit to resolution acuity in the periphery. However, reduced image quality from optical aberrations may also influence peripheral resolution. In this study, we investigate the impact of different degrees of optical correction on acuity in the periphery. We used an adaptive optics system to measure and modify the off-axis aberrations of the right eye of six ...

Optic neuritis is commonly associated with diseases such as Multiple Sclerosis, infections, taking special drugs, etc. but recently we have observed a patient that presented retro bulbar optic neuritis as a manifestation of antiphospholipid syndrome. A 35 y/o young woman with the history of chickenpox admitted to the Qhaem hospital (Mashhad, Iran) with the c/o progressive pain and blurred visio...

Clinical color-vision tests are evaluated within the framework of a model of chromatic discrimination in terms of cone excitation. The motivation for this study was to derive a method for evaluation of test design, test sensitivity, and observer performance. The discrimination model is based on the assumption that chromatic discrimination is mediated in two independent channels, one for short-w...

When interacting with our environment we generally make use of egocentric and allocentric object information by coding object positions relative to the observer or relative to the environment, respectively. Bayesian theories suggest that the brain integrates both sources of information optimally for perception and action. However, experimental evidence for egocentric and allocentric integration...

background and aim: attention is an important cognitive process that is necessary for educational purposes. blind people are deprived from the most widely used human sense, the sense of vision. there are reports that blind individuals have a significantly better performance in attentional tasks, as compared with normal subjects. the purpose of this study was to evaluate sustained auditory atten...
