The Kajimoto laboratory (part 2): Muscular laugh enhancement

For another cross-modal human/computer research project [see previous article in this series] which has been developed by the Kajimoto laboratory (a department of The University of Electro-Communications, Tokyo, Japan) investigates ‘The Enhancement of Laugh by using Muscle activity’, [note: paper mostly in Japanese]


“On television show, we are familiar with artificial sound of laughter so called ‘canned laughter’ or ‘laugh track’. It generally has an enhancement effect of human’s laugh. However, if the sound is played when the user dislike the contents, it works negatively. To cope with this problem, we propose a system that produces the laugh track synchronized with the user’s laugh motion. We use a myoelectric signal from diaphragmatic muscle to detect initial laugh, and dolls around the user to produce laugh sound. We speculated that although initial laugh trigger from the user is necessary, the system still can effectively enhance the laugh activity, and even affect the subjective quality of the contents.”

The lab has provides two movies about the projects [in mpg and mp4 formats] movie [1] and movie [2]
