高齡者資訊服務網站階層式導覽結構之使用性研究

Study on the Hierarchical Navigation Structure and Utilization of Information Service Website for Elder

指導教授 : 許明潔

摘要


在21世紀的社會環境同時面臨資訊科技進步及人口高齡化的挑戰。伴隨著網路資訊的成長,目前網際網路已是一個複雜的超媒體空間,容易造成使用者產生認知負荷的情況。其中,網站導覽結構是影響網路使用者認知負荷的重要因素之一,對認知能力逐漸退化的高齡者更是為之重要。網站設計者應以使用者中心為設計考量,但現今網路的資訊服務網站平臺,大都未將高齡者族群的使用性納入網站設計考量,使得高齡者比起一般使用者更容易在網路遭受使用上的困難。本研究將透過資訊服務網站進行現況分析以提出研究假設,利用實驗法檢驗其階層式導覽結構的差異與使用性的影響。研究結果顯示,高齡者在資訊服務網站導覽結構設計中,是以「群組階層式(Associative hierarchy)」導覽結構的使用性顯著優於「絕對階層式(Strict hierarchy)」及「多維階層式(Multi-dimensional hierarchy)」。因此本研究建議網站建置,應以在相同群組中可垂直跨階層的導覽結構設計為主,對使用者而言,可容易地使用網站,以快速正確找到所需資訊;對管理者而言,較不易因使用者多次不必要的點選動作,而造成網站伺服器的負擔,期望能讓網站設計師在導覽結構設計上能有所參考依據,使更多高齡者享受電腦網路的益處。

In the twenty-first century, societies face challenges brought by advancing information technology and aging populations. With information technology development, the Internet has become a hypermedia space that abounds with information, and easily subjects users to heavy cognitive loads. Among others, website navigation structure is a crucial factor that influences user cognitive load, especially for elder who suffer from degenerating cognitive abilities. Although designers should construct websites based on user needs, most current online information-service platforms do not consider the usability of elder, thereby increasing the difficulties elder face when using the Internet. This study analyzed the current structures of information service websites and proposed a research hypothesis. The experimental method was employed to understand the differences among several hierarchical navigation structures and their usability. The results revealed that, for elder, an associative hierarchical structure provides greater usability than that of strict and multi-dimensional hierarchical structures. Therefore, this study suggests that website designers should consider a navigation structure that vertically links different stratifications in the same group. Users can navigate the website easily and locate desired information quickly and precisely. Regarding website managers, the operation load of website servers can be reduced because unnecessary clicks on the site by users are lowered. The results can serve as a reference for designers of website navigation structures to provide increasing elder users with improved Internet benefits.
