Abstract: The aim of this study is to investigate the problems and needs of users with advanced age and cognitive impairment regarding the design and operation of daily living products. Television remote controls and an electric rice cooker were applied as the research tools, and focus group interviews with control older adults and interviews with individuals with MCI or mild dementia were conducted regarding the operation of the products. The control participants stressed that the operating procedures should not be excessively complex, the number of functions and buttons should not be overly high, and buttons and text should be enlarged. For those with MCI or mild dementia, in addition to the size and number of buttons, text size, and functions, their operation of product interfaces was affected by the complexity of the operating procedures. The solutions recommended by the participants included interface design involving direct operation and voice control.
