Many powered wheelchair users have difficulty manoeuvring in confined spaces. Common tasks such as traversing through doorways, turning around in halls or travelling on a straight path are complicated by an inability to accurately and reliably control the wheelchair with a joystick or other common input device, or by a sensory impairment that prevents the user from receiving feedback from the environment. An active joystick with force feedback to indicate obstacles in the environment has been developed. Two force feedback schemes designed to assist a powered wheelchair user have been developed and implemented using the active joystick. The development of the joystick and associated control algorithms are described.
许多电动轮椅使用者在狭窄空间内操纵轮椅存在困难。诸如穿过门口、在走廊转弯或沿直线行驶等常见任务，会因无法使用操纵杆或其他常见输入设备准确可靠地控制轮椅，或因感觉障碍导致使用者无法接收来自环境的反馈而变得复杂。一种带有力反馈以指示环境中障碍物的主动式操纵杆已被开发出来。利用该主动式操纵杆，已开发并实施了两种旨在协助电动轮椅使用者的力反馈方案。本文描述了该操纵杆及相关控制算法的开发过程。
