User Centred Design Utilizing Sensory Analysis
Abstract This paper discusses User-Centred Design (UCD) utilizing a sensory analysis method applied to the initial stage of a new machine designed to meet users requirements. Because of the initial lack of a specific requirement balance, interface designers are required to measure and analyze the value of a user's comfort level. User requirements are observed from an environment aspect in context of use. This paper compared Japanese user requirements with user requirements from other nationalities with varied environmental backgrounds since there are difficulties in defining a general user category group. For the analysis, nine samples were selected as experimental Portable Information Terminals (PIT). The required measurement and analysis was accomplished by combining proposed Marble Method and Correspondence Analysis. In order to validate the analysis results, the correspondence analysis plot charts were shown to expert designers and project managers involved in the design and manufacturing process. It was concluded that the general users group characteristics and proposed method reflect the requirements at the survey and planning step, specification forming step and revision step of the process.
