Perceptual Information for User-Product Interaction: Using Vacuum Cleaner as Example
Li-Hao Chen, Chang-Franw Lee
The purpose of this study is to identify which product designs for parts and directions are most effective, and then propose how perceptional information could best be designed to facilitate user-product interaction. Three categories of perceptional information for product operational tasks were proposed in this study. Task analysis and usability evaluations were carried out to analyze what information users required while they practiced the operational tasks. Finally, a primary model was proposed that revealed and defined specific types of entities and different perceptual information— Behavioural Information (BI), Assemblage Information (AI), and Conventional Information (CI)— to be significant elements for the model. Information for specific applications that is available for various types of vacuum cleaner parts is described below: 1) for specific operational tasks, these applications for operability, functionality and operational directions are required for the user-part category, and BI and CI provide effective support for the applications; 2) the application for assembly-ability is required for the part-part category, and AI and CI provide effective support for this application; and 3) the applications for operability, functionality, operational directions, and assembly-ability are required for the user-part-part category. BI and CI provide effective support for the applications for operability, functionality, whereas operational directions, and AI and CI provide effective support for the application for assembly-ability.
