For example, there exist some wheelchair users, who cannot operate a powered wheelchair well by using a joystick, which is usual manipulation equipment of powered wheelchairs. A prototype of our group has simple manipulation equipment, constructed by buttons or levers. This operation equipment restricts the running performance of wheelchair. On the other hand, due to the restricted running performance,...
We develop a one hand drive wheelchair with original manipulation mechanism and power assist mechanism. In this investigation, first, we improve the transfer mechanism of this wheelchair. As a result, using an improved mechanism, the running resistance of the wheelchair decreased with about 1/2 to the previous one. The effects of this improvement are verified by long distance drive experiment using...
A one hand drive wheelchair with power assist mechanism is developed. In this investigation, we propose a simple and useful manipulation torque detection method which yields wide detection areas with uniform distribution of stress. This method can be applied to a one hand drive wheelchair with complicated structure of manipulation mechanism with three rings. Moreover, even if the grasping position...
We are developing a guide robot and an autonomous small vehicle to assist the visually impaired person and the aged. Various functions for support are installed in the guide robot, especially, obstacle avoidance functions necessary to ensure the safety of the user. When the guide robot is moving, the avoidance of not only the static objects but also moving objects is necessary. As the guide robot...
A one-hand drive wheelchair with power assist mechanism is developed. We have proposed a manipulation mechanism with a triple ring and some assist functions. In this paper, the effect of the assist function compensating an increase of the running resistance is newly discussed The effectiveness of the assist functions is verified through experiments using a prototype, developed in our research group.
Purpose of our works is development of an interface by eye movement for physically impaired people due to spinal cord injury and neurological disease. Eye appearance is changed by eye blinking, head motion, eye movement, and individual difference. Moreover, the system must track the eye and acquire its information simultaneously. For these problems, we use genetic eye tracking method with an artificial...
Now, the interface environment of information equipments such as computer remains the former style using keyboard and mouse. To allow elder or handicapped people to use such equipments, a system helping them use the equipments much easily is needed. In this paper, a dialog system will be shown which permits both human and computer (hereafter it is called a system) to use verbal/non-verbal communication...
