IT技術演進，將資訊科技與電腦整合融入汽車成為「智慧車」是目前的最新趨勢。智慧車中的車用電腦整合了多項功能，成為使用者與智慧車互動的重要系統之一，使用介面設計不良的車用電腦，在使用上費時費力，使用者也必須花費較多注意力資源在操作系統，因此介面設計必須充分配合使用者需求，才能有效且安全地利用系統，達到人車一體的境界。
本研究以情境著手，實際操作車用電腦系統，並錄影紀錄使用過程，對系統中的七項主要功能：(1)影音娛樂、(2)撥打電話、(3)傳送簡訊、(4)衛星導航、(5)行車安全、(6)車主專屬、(7)系統設定進行情境分析，以全面了解操作流程。再整理國內外文獻，找出在使用情境中的各項設計指引。最後建置「車用電腦情境資料庫」，包含具有共通性原則的控制器設計、顯示器設計、及系統功能中的電話通訊、衛星導航，並將整理出的各項設計指引彙整在情境資料庫中，以供未來依照資料庫中的各項指引對系統進行量測及評估。
建置情境資料庫完成後，經由與合作廠商之工程師討論後，確認所建置的資料庫可輔助產品開發中的設計及可用性評估階段，在產品開發的設計階段，資料庫中L1-L3層級的情境可以讓產品開發人員根據情境找出使用者的需求；L4-L6層級的指引可以提供產品設計時具體的參考數值及設計依據。在可用性評估階段，可依據L1-L3層級描述的情境檢視系統設計是否符合L4-L6層級的指引，節省執行可用性評估時花費的時間與人力。

Car-PC in intelligent car integrates multiple subsystems and becomes one of the most important bridge for connecting user and vehicle. Using car-PC with poor interface design can cost time and increase mental load. Poor user interface will take more “Attention Resource” from the user in operating the system. Interface design must consider “Usability” and satisfy user’s need to allow users interact with the system more effectively and safely. This study derived usability specification of Car-PC based on collected scenarios of Car-PC use. Seven functions of Car-PC: (1)Multimedia, (2)Mobile Phone, (3)Message, (4)Navigation, (5)Safety,(6)Personal, (7)System Setup were taken into consideration to derive scenarios for usability evaluation. The scenarios were tabulated in terms of environment, scenario, and required action plus the usability attribute, measurement concept, and measurement method. The usability attribute, measurement concept and measurement method mainly come from the ergonomic design guidelines. Since input and output devices can be shared by different functions, the design guides of input device (control) and output device (display) were tabulated separately from the seven functions. These scenarios and usability specifications were integrated into a scenario database. Two engineers were interviewed to express their concerns and suggestion for the scenario database. Scenarios can help to identify users need while usability attribute and measurement method can provide objective standard for product design. Usability testing of the Car PC can be performed by evaluating each scenario through usability attributes.
