近年來由於電腦科技的進步,已促使復健工程領域運用高度的電腦技術來提昇對肢障者的協助;然而,肢障者往往需要藉由特殊的介面方能與電腦溝通,因此提供肢障者與電腦間的良好溝通介面,將有助於提昇肢障者獨立生活的能力。
本研究即針對肢障者的實際需求,找尋市面上販售之滑鼠加以改裝,並利用力量感測、雜訊濾波、位準調整等工程技術,設計製作出適合頸部、下顎、腕部、以及肘部使用之電腦游標控制裝置。
經由肢障者之實際操作測試與主觀評價,證實以其他控制精確度較差之身體部位來進行滑鼠控制時,為了獲得較佳之精確控制性必須調高滑鼠之控制/反應比(C/R ratio),如此一來便會造成速度績效的下降,因此,如何找出肢障者身體各部位之最佳組合,便成為選擇滑鼠的最重要考量。
研究中的腦傷及脊髓損傷患者,經過提供適當的滑鼠及分離式按鍵配置後,其對電腦作業的控制能力有了顯著的提昇,並能夠具備完整的滑鼠作業能力。同時,本研究所開發的力感測式滑鼠,其操作績效與軌跡球相近,透過訓練與學習之後彼此間應具有替代性。
Progress made in computer technologies has encouraged rehabilitation engineers to apply computer technologies in helping disabled people to enjoy greater degree of independence in their daily living. However, a handicapped person may still rely upon special interface to communicate with a computer. Providing physically disabled persons with adequate human/computer interface may thus contribute greatly to improve their independence.
This study takes two approaches to provide suitable controllers of mouse cursor that applied to a person’s neck, chin, wrist, and elbow to the disabled. One approach is to search and modify computer mice commercially available. The other approach is to develop force-sensing controllers by utilizing force sensing, signal filtering, and threshold adjustment technologies.
Performances of disabled subjects in operating computer mouse were evaluated according to practical tests and subjective evaluation. The results show their better performance can be achieved by trading their speed with accuracy. This can be done by increasing control / response ratio (C/R ratio) of the mouse. However, how to decide the best combination of one''''''''s functional controllability so as not to sacrifice too much of his speed has become the most important consideration in choosing an adequate mouse.
By providing adequate mouse and an isolated clicking switch, performances of patients with brain injury and with spinal core injuries were significantly improved. Performance achieved in the developed force-sensing mouse by subjects was found close to that of a trackball. This suggests these two computer mice are interchangeable to some of the disabled.
