The purpose of this study is to propose the wheelchair system enabling hemiplegic users to steer the wheelchair by one hand drive. This system consists of two parts: extraction of user's control intention from the single hand rim and the front wheel system with active steering. In particular, this paper focuses on the feasibility verification of this system and to propose the front wheel system. For...
The objective of this research is a development of the mechanism which assists the wheelchair user to climb a step. We designed the wheelchair caster unit which has a assistive mechanism. This unit is easily replaced with the conventional wheelchair caster. The proposed caster unit has two functions for assisting a step climbing. One is the assistive plates for enlarging radius of the caster imaginarily...
We developed the virtual human model by using freeware. This model is easy to introduce into the initial stage of research, because it uses Open Dynamics Engine (ODE), which is an open-source software, and is easy to be modified as to various demands. In this paper, first, we explain the virtual human model using ODE. Next, we indicate the problem which comes from ODE, and propose the solution. Then,...
