Although eyes and upper limbs work together over the whole course of arm movement, vision usually dominates in visual-haptic perception. The dependence of the brain on visual information is demonstrated by the wide variety of visual illusions, such as “shade and shape,” that have been developed. In order to quantitatively measure upper-limb motion, a haptic device can be used to obtain numerical data...
This paper intoduces a preliminary study on a new control decomposition criterion for collaborative teleoper-ation systems — field of view deficiency. This criterion represents the amount of visual information available to operators. As a tool for such decomposition we introduce a dominance distribution matrix — a more flexible approach to dominance distribution than a well-known scalar dominance...
In this paper, we present a novel use of haptic information in extended range telepresence, the wide-area haptic guidance. It consists of force and position signals applied to the user's hand in order to improve safety, accuracy, and speed in some telepresent tasks. Wide-area haptic guidance assists the user in reaching a desired position in a remote environment of arbitrary size without degrading...
We present an approach for implementing a virtual reality system targeted at learning handwritten characters. We especially aim at enabling learners to acquire important writing skills required to be a good writer in Japanese calligraphy. The proposed system provides a haptic channel allowing the learners to intuitively master an instructor's fine motor skills through the sense of touch. We utilize...
Touch sensation called ??haptic?? interface attracts increasing attentions from many researchers as a way for providing a new interaction modality. Integrating the haptic interface with traditional audio-visual communication channels has a potential ability to create more sophisticated human computer interaction (HCI) method and application systems. One big hurdle for utilizing the haptic interface...
We present an approach to realize an e-learning system targeted at teaching handwritten characters. In addition to realistic 3D graphics rendering of written characters, our system provides a haptic channel to intuitively learn an instructorpsilas fine motor skills through the sense of touch. We utilize a commercially available haptic device called PHANTOM. The proposed system implements a function...
Cyberworlds could be a platform for both research and e-learning particularly in research intensive disciplines such as biology, physical chemistry, molecular medicine, biophysics, structural biology, bioinformatics, etc. The computer simulation of assembling molecules has been studied intensively in the field of computer-aided rational drug design. The assembly of molecules in a three-dimensional...
