手部功能受損之障礙者通常需利用特殊設計之指標輸入裝置方能操作電腦。一款輸入裝置整合器(IPDA)被開發來協助肢障者以身體其他部位操作滑鼠等一般市售指標裝置。本研究即針對IPDA之使用,透過系統性的測試,探討手部功能限制對指標裝置操作績效之影響,以及一般人主觀對電腦指標操作最低可接受的績效。研究中測試30名理工研究生,在以護木限制手臂活動功能的情況下,透過IPDA整合功能,分別以單手控制滑鼠或軌跡球、以單手腕控制轉向滑鼠、以兩前臂分別控制軌跡球與滑鼠按鍵、以下巴及前臂合力控制軌跡球與滑鼠,控制游標執行「移動點選」及「拖曳施放」之操作績效。上述實驗結束一週後,受側者藉由目視電腦指標作業之流暢度,主觀決定「移動點選」與「拖曳釋放」2項操作之「最低」可接受操作績效。實驗測量與主觀判定之操作績效均以未受限制下操作一般滑鼠之平均績效(100%AP)進行標準化。
結果顯示以單手遠端操作指標裝置之績效,明顯優於整合多進端部位操作指標裝置之績效,但整合多進端部位之控制方式其績效仍可接近正常人操作一般滑鼠的50%。以兩前臂分別控制軌跡球與滑鼠按鍵進行「移動點選」及「拖曳施放」之績效,分別為53%AP與55%AP;而以下巴控制軌跡球與前臂控制滑鼠按鍵進行「移動點選」及「拖曳施放」之績效,分別為46%AP與43%AP,這兩種困難度較高的控制方式,所得操作績效仍高於主觀「最低」可接受操作績效(「移動點選」約22%AP;「拖曳釋放」約24%AP)。
本研究建立使用IPDA時不同指標控制方式之操作績效,以及主觀「最低」可接受績效範圍。比較本研究與前期針對脊髓損傷者(SCI)之研究結果得知,多數SCI肢障者可經由IPDA裝置的使用獲得可接受之績效。本研究所建立之IPDA控制方式與操作績效,可作為未來設計電腦相關輸入裝置之參考。
Persons with impaired hand function usually rely on using specially designed pointing devices to operate computers. An integrated pointing device apparatus (IPDA) was developed to facilitate the computer operation of people with impaired hand function in controlling ordinary pointing devices, such as mouse, by their different body parts. A series of systematic tests were conducted in this study to explore the effects of hand-arm functional limitation on the operational efficiency (OE) of ordinary pointing devices, and the lowest operational efficiency which common people can accept in subjective. Target acquisition and drag-and-drop OE of 30 engineering graduates were tested without or with their finger, wrist, and elbow movement restricted by a splint. Accordingly, subjects controlled cursor movement and clicking by one hand and a mouse/trackball, by one wrist and an orientation-rotated mouse, by forearms together with a trackball and a mouse, by chin and forearm together with a trackball and a mouse, via IPDA integration function. One week after the operational efficiency experiment, subjects observe the fluency of the computer pointing operation task by using visual, and decide the lowest OE that target acquisition and drag-and-drop. Measured OEs were normalized according to the average efficiency of no restriction test, i.e. 100% OE of able person (%AP). Results showed that the average OE subjects obtained by employing single body part was superior to that of employing two higher parts of the body, but the average OE of employing two higher parts of body was closed to the half OE of common people use of mouse by usual hand. The average OE of target acquisition and drag-and-drop were about 53%AP and 55%AP, respectively, using a trackball and a mouse together by bilateral forearms, and the average OE of target acquisition and drag-and-drop were about 46%AP and 43%AP, respectively, using a trackball and a mouse together by chin and a forearm respectively. Although those two control modes have higher difficult operation, average OEs in tests are higher than the lowest OE in subjective (“target acquisition: 22%AP, drag-and-drop: 24%AP). This study not only establishes OEs in different operation modes when using IPDA, but also builds the lowest OE which common people can accept in subjective. Compare this study results with earlier study results about Spinal Cord Injury Patients, most SCI patients to obtain an OE that common people can accept by using IPDA. Those results about IPDA control modes and OEs can be as the reference that computer input device is designed in the future.
