台灣地處亞熱帶,氣候較為潮溼悶熱,加上近年來經濟發展後帶來都市化現象,加速熱島效應產生,使得台灣居住環境缺少不了冷氣 (空調機)。在冷氣遙控器操作過程中,視障者因無適當資訊的回饋導致學習與操作上的困難。本研究以視障為對象,對目前冷氣遙控器的介面進行探討。首先進行使用現況分析以及問卷調查,探索視障者使用上的實際需求與問題點。透過分析與歸納,結果顯示下列四個問題:資訊傳遞不佳、使用者判斷正確率低、按鍵功能無法讀取、學習與記憶困難。本研究之目的在於針對上述操作冷氣遙控器所衍生的問題,加以研究探討,設計出讓視障者能方便操作的冷氣遙控器。 在問卷調查中確認研究範圍限定在電源、溫度、風速、風向、定時、睡眠等六項功能後,針對問卷調查所得問題點,各項功能進行設計改良2~4種方案,並進行實驗原型製作;為找出最適切的方案組合,進行下列三項實驗:各功能樣式確認實驗、功能排列順序實驗、點字安裝位置實驗。交叉比對結果,確認最後測試用組合方案,再和現有冷氣遙控器進行任務性問卷測試。 任務性問卷分為三項任務:按鍵功能辨認、現有狀態讀取、操作任務測試。比較新設計與現有設計在位置尋找正確率、操作方式正確率、詢問率的異同。結果顯示,新設計改善了資訊傳遞不良的情形,且判斷正確率比起現有設計提升許多,按鍵功能透過點字和浮凸圖像附加能夠順利讀取,學習與記憶亦獲得改善。本研究結果可供視障者家電產品設計研究作為參考。
Taiwan is situated in the subtropical zone with high temperatures and humidities. Urbanization as a result of economic development in recent years accelerated the heat island effect and made air conditioners indispensable to the living environment around Taiwan. Due to a lack of appropriate information feedback, the visually impaired often experience difficulties in learning how to operate the remote for air conditioner. This study focuses on the visually impaired and examines current interface on remote control for air conditioner. It first conducts current use analysis and questionnaire survey exploring the actual need of the visually impaired in using the remote control and the problems they encounter. Through analysis and induction, it identifies the following 4 problems: poor information transmission, low judgment accuracy of users, inability to access information through the press buttons, and learning and memory difficulty. This purpose of this study is to delve into the problems arising from operation of the remote control for air conditioner and design a new one that is easy to use for the visually impaired. The scope of the questionnaire survey is limited to 6 functions: power, temperature, wind speed, wind direction, time setup and sleep. Based on the problems identified via the survey, 2-4 improvement proposals are prepared for each function, and the experiment prototypes are made. To identify the optimal proposal combination, the following 3 experiments are conducted: individual function pattern verification experiment, function layoyt ranking experiment, Braille installation position experiment. Outcomes of cross comparison confirm the combination proposal for final testing. Task-oriented questionnaire testing is conducted on comparison between current and new design remote control to verify the accuracy and actual effect. The task-oriented questionnaire is divided into 3 task: press button function recognition, current status access, operational task testing. The new design and current design are compared in terms of location search accuracy, operational method accuracy and inquiry rate. The outcome indicates the new design rectifies poor information transmission; in comparison the current design the judgment accuracy has been significantly enhanced; through the addition of Braille and relief icons the functions of the press buttons can be easily accessed; learning and memory also show improvement. The findings of this study can serve as reference for design and study of home appliances for the visually impaired.
