Everyday Life ToDo Display on Ceiling for Smart Living Space

摘要

Many commonly used household appliances and equipment include refrigerators, washing machines, intercoms, telephones, air conditioners, microwaves, and ovens; they communicate various information to the users by providing notifications using auditory displays. However, an occupied user may not pay attention to the notifications and/or cannot recognize simultaneous auditory alerts. Therefore, in this study, we propose a ceiling display system that displays information depending on the location of the users. This display system utilizes house ceilings as overhead visual displays that can update the users with various information simultaneously. This paper describes the different situations where appliances notify the users on completing a task; subsequently, we propose a concept for the ceiling display system in a smart house that will be introduced in the near future. In addition, the expected effectiveness of this system, some useful scenarios, and initial verifications of the visual notifications on the ceiling are described.
