Relationship Between the Complexity of System Functions and Amount of Displayed Information on a Mobile Device with Touch Display

Multifunctioning systems are being extensively used in households these days. System information is summarized on a portable terminal. Users benefit from the value produced by multifunctional systems. Therefore, it is conceivable that the motivation to use such systems can increase or decrease depending upon the balance between the amount of information on the terminal screen and the amount of system information. Additionally, the elderly are assumed as next-generation users. Thus, in this study, from the viewpoint of motivating the elderly, we explore the relationship between the amount of information on the terminal screen and the amount of system information. As an experiment, we create a smartphone application that can control the amount of information, and the participants performed a task in which varying amounts of information were combined. As a result, a relationship between the amount of information on the terminal screen and the amount of system information was found.
