| Summary: | 碩士 === 實踐大學 === 工業產品設計學系碩士班 === 102 === Public utility design is supposed to consider all types of user scenarios and habits. Not only to provide convenient services, but also to avoid unwanted outcome that is caused by improper use. Designers should be more careful and pay special attention to these phenomena in order to create better user experiences. This research examined the inappropriate design of the public utility products from the perspective of universal design principals. The analysis on the overly labeled products was conducted for the public utility product used in the fields of public affairs, administration and education within the follow locations, convenient stores, partaking lots, self-service laundry, library, and offices. Products examined in this study included coffee vending machine, microwave oven, auto pay machine, laundry machine, copy machine, 24h FastBook system, audiovisual equipment, telephone, and transcript management system. The results summarized 32 inappropriate designs from the perspective universal design principals.
(1). Products that do not comply with the Principle of Equitable: The operation procedure is not simplified enough for the elderly; product operation needed more physical effort does not consider the workload limits of the elderly. (2). Products that do no comply with the Principle of Flexibility: The restriction of coins used in machines and, restrictions of specific types of functions. (3). Products that do not comply with the Principle of Simple and Intuitive Use: The controller panel lacks of the ability to help users to identify different functions in which a single switch that has multiple functions. The lack of feedback to inform users at different types of scenarios that confirmation message is suggested in certain steps or stages. (4). Products that do not comply with the Principle of Perceptible Information can be found with language barriers, icons that are difficult to interpret, colors that are not easily noticed, lack of pictorial symbols, lack of contrast in the appearance, unclear instructions, small fonts, ill-designed interface layout, lack of similarity information, unclear design flow, users lack of the proper instructions, products that do not provide enough instructions. (5). Products that do not comply with the Principle of Tolerance for Error: products lack of the ability to troubleshoot, and lack of foolproof design. Design tips based on the research findings were recommended for the future design of the public-utility product.
Keywords: public utility products, Principle of universal design.
