HomeOrgel: Interactive music box to present actual home activities with symbolic sounds

We propose a music-box-type interface, “HomeOrgel”, which can express various activities in the home using sound. Users can also control the volume and content using common methods for controlling a music box: opening the cover and winding the spring. This system helps users look back on past activities in the home using sounds, imitating the recall of memories using a music box. We developed the HomeOrgel device and installed a simple activity recognition system in an actual house "Ocha House" to verify the effectiveness of the HomeOrgel using actual data.
