本研究以服務體驗洞察法針對失智長者時間定向感認知障礙進行探討與分析，找出改善失智長者時間定向感認知之潛在需求，作為改善時間定向認知的產品設計新契機。透過觀察現況與分析失智長者的活動，彙整服務體驗洞察結果，提出改善失智長者時間定向感認知障礙之產品設計要點。本研究針對雲林縣某老人養護中心的失智長者進行實地觀察與訪談，針對輕、中度失智症族群，利用脈絡訪查彙整行為模型，標示出障礙點與需求點，透過專家焦點團體訪談提出產品設計需求與方針，其整體需求主要有5點：「增加熟悉度」、「以互動增加期待感」、「增加時間提醒裝置」、「桌上型園藝活動」及「提高專注力」，據上述需求彙整出改善低、中失智長者，對時間定向感之認知障礙的設計標的，結合日常活動與季節相關資訊圖像，改善失智長者的時間定向感認知。

This study uses service experience insight method to examine time disorientation cognitive impairment in elderly persons with dementia. The aims were to improve the sense of time orientation in elderly persons with dementia by observation and by analyzing the problem of deactivation of demented elderly, to reorganize service experience insights, and to put forward product design considerations for improving perception of time in the elderly with dementia. A field observation and interview were conducted on each elderly subject with dementia in an elderly care center in Yunlin. A target personage was then constructed and venation was used to check the behavior model and to mark the barrier and demand points. Expert focus groups were then conducted which put forward the product design requirements and guidelines. There were five requirements: ＂increasing familiarity＂, ＂increasing the sense of anticipation through interaction＂, ＂adding time reminders＂, ＂tabletop gardening activities＂ and ＂increasing concentration power＂. From these requirements, the product design framework and target design were compiled and developed. Daily activities were combined with seasonal information images and improved clock design complemented by horticultural elements in tabletop games to improve the time perception of elderly with dementia.
