Application of Haptic Interface to Produce Haptic Illusion in Virtual Environment

WYSIWYF Display: A Visual/Haptic Interface to Virtual Environment

To build a VR training system for visuomotor skills, an image displayed by a visual interface should be correctly registered to a haptic interface so that the visual sensation and the haptic sensation are both spatially and temporally consistent. In other words, it is desirable that what you see is what you feel (WYSIWYF). In this paper, we propose a method that can realize correct visual/hapti...

Haptic Virtual Environment Performance

This paper reports on the performance of Distributed Haptic Virtual Environment (DHVE) applications deployed over policy-based IP networks. Our previous work reported that a best effort service in IP networks is inadequate for satisfying the Quality of Service (QoS) requirements of such applications. The current work tries to find out whether applying differentiated Services (DiffServ) satisfie...

MoVE: Mobiltiy Training in Haptic Virtual Environment

The proposed MoVE system is a virtual environment for shape learning and mobility training of the blind. Our goal is to provide an environment where a visually impaired person would be able to form cognitive maps of a new place they might visit in future. Cognitive maps are mental models of the relative locations and attribute phenomena of spatial environments. Ability to form cognitive maps is...

Modeling Virtual Hands with Haptic Interface Device

For direct manipulation environment with force feedback, we propose a kind of string-based two-handed multi-fingers haptic interface device. The system can sense the positions of three fingertips and wrist on each of the user's hand. Force feedback can be perceived when the position of the finger comes into contact with the virtual object. We explain in detail about the algorithms used in the f...
