Interface Design and Usability Evaluation in Digital Signage System

[[abstract]]創新與多元化資訊內容服務，於多媒體網路科技擴散應用後，結合商業模式並帶來更多發展潛力。數位廣告透過不同媒體載具，已廣泛運用於實體商業環境。現今多數商業經營者採用數位廣告看板系統於液晶顯示器上進行廣告內容推播，系統提供商依據產業類別開發出具備穩定性、成本考量或重視閱覽者視覺傳達面等各性質數位廣告系統。直至同業競爭者及潛在進入者相繼提供產品服務後，以顧客需求發展客製化系統服務，便成為產品發展策略之選擇。 本研究自發展開發流程開始，逐步將文獻探討內能給予系統介面設計的數位廣告看板建議，應用於數位廣告看板系統介面設計。系統雛型評估採用使用性評估方法，並對介面設計動態操作模式部分進行設計原則的評量。採用系統使用性量表，能藉由量表分數得知評估者觀點中雛型的使用性表現程度。本研究綜合系統功能與介面設計原則構成系統介面設計過程，以及雛型評估結果做出整體結論。結論如下： 1 播放清單為數位廣告看板系統必要功能，好的功能介面需考量排程設定與包容基本的媒體檔案形式，並且能重視人員操作與更換廣告內容的需求。 2 由於播放媒體形式不同，系統介面應更重視各個主要功能操作邏輯與流程的設計。對整體介面而言，也必須能達到整合與一致性設計。 3 系統必須著重於錯誤訊息產生機制與輔助說明的設計。可先藉由視覺化步驟、路徑指引、流程圖等表現方式，改善使用者對於系統正確操作的認知。而後建立起好的錯誤訊息回饋機制。 4 操作上就算系統開發中考慮並採用一般使用者操作習慣，配合評估者驗證出的確符合類似系統操作經驗。但針對初次使用的使用者仍需要適度輔助說明。[[abstract]]After the proliferation of multi-media Internet technology Innovation and diversity of content services are integrated with business model They bring more development potential to this word Digital advertisement has been widely used in physical business environment through various media Today most commercial operators use digital signage in the liquid crystal system to push advertisement on the displays then system providers also develop different digital signage systems that including stability cost consideration viewer’s visual communication feelings or other elements by based on industry category Since the competitors and potential entrants had provided product service to customized system services it has become the choice of product development strategy In system development process the design suggestions of digital signage were collection from literature review then to be implemented in interface design Including usability evaluation methods evaluation of the dynamic interface design principles and system usability scale were adopted at the stage of prototype evaluation Using system usability scale could find out the performance from evaluators’ view After that there was a conclusion made by integrating the process of system interface design and the results of prototype evaluation: 1 Playlist is one of the necessary functions in digital signage system Not only is it important to consider how to design the playlist and choose the suitable forms of media but also it is important to seriously think about the requirement of operators 2 According to the different forms of media system interface must focus on each function’s logic and process design To the whole interface it is necessary to integrate and design consistency from each interface element 3 System interface must focus on design of help and the feedback of error messages So related research can improve the cognitive of correct operating activities by visual steps guides of operating and work flow charts 4 Although system operating activities and user’s habits are considered in system development then conforming to related system operating experiences It is necessary to provide helps and document
