摘要

隨著科技的發展，產品大多訴求輕薄短小、功能多，導致介面愈來愈小，冷氣機遙控器也不例外。在這樣的設計趨勢下，如何顧及到高齡使用者的需求，成為設計師必須克服的議題。因此本研究以探討遙控器介面上影響高齡者易識性因素為目的，並對該因素提出設計之參考。
本研究包括市場調查、問卷調查與兩項實驗：經由市場調查，蒐集及比較 12 支現有冷氣機遙控器，以瞭解冷氣機遙控器的現況，並從其中挑選出 6 款，由 20 位平均年齡 70.45 歲之高齡者進行問卷調查，發現文字/背景色彩組合為影響易識性的重要因素；接著將 110 種色彩組合以螢幕模擬方式對 22 位平均 67 歲之高齡者進行測試，得到易識性及喜好度交叉比對結果與綜合排序結果，再藉由此結果篩選出 32 組色彩組合，請 26 位平均年齡 73.21歲的高齡受測者進行實體樣本實驗。
經 Durbin test、單一平均數 t 檢定及相關係數分析，結果顯示：(1) 選擇文字/背景色彩組合時，可採用易識性及喜好度皆佳之白/黑、紅/黃、黑/黃、白/紫、白/紅、黑/粉組合；而避免使用灰/粉、粉/黃、灰/橘、紫/黑；(2) 色彩組合之明度差與易識性及喜好具有強烈正相關，而與色差、彩度差、色度差不顯著相關； (3) 負顯示模式提供高齡者較佳之易識性；(4) 易識性與喜好度具有非常強烈的正相關性。

Along with the advances of technology, most products nowadays boast its ultra-lightness and thinness as well as its multi-functions. Such development induces smaller user interfaces on products, among which include air-conditioner remote controls. With a trend as such, the challenge of designing products that meet the needs of elderly users has become critical and imminent. This research is thus dedicated to explore the elements on remote controls’ user interface which affect the elders’ legibility, and duly propose suggestions on its overall design.
The research consists of market surveys, questionnaire surveys, and two experiments. Twelve marketed air-conditioner remote controls were collected and compared through market surveys to fully appreciate the status quo of AC remote controls. Questionnaire surveys on six selected AC remote controls available on the market were later carried out among twenty elders aged 70.45 in average, thus revealing that the color combination of text and background greatly affects legibility. A group of 22 elder aged 67 in average then proceeded to receive a screen simulation test of 110 different color combinations. By cross referencing and ranking both elements of legibility and preference, a final of 32 combinations were selected, which were to be sample tested on 26 elders aged 73.21 in average.
It is founded through Durbin test, one-sample t test and correlation coefficient analysis that: (1) to pursue higher legibility and meet preferences, it is optimal to select text and background color combinations such as white versus black, red versus yellow, black versus yellow, white versus purple, white versus red, or black versus pink, while avoiding combinations of gray versus pink, pink versus yellow, gray versus orange, or purple versus black. (2) Legibility and preferences are positively related to lightness difference of color combinations, while less so with color difference, chroma difference, and redness-greenness difference and yellowness and blueness difference. (3) Negative display modes provide better legibility for elder users. (4) Legibility and preferences are significantly positively related.
