enjoy and practice Laughter Yoga anytime and anywhere. With Laughter Catcher, users can record their laughing yoga videos to send to their friends so they can mimic their laughter, too. Laughter catcher is a mobile app that lets users mimic laughter from their friends and record their own laughter yoga videos and share it with others. The user only needs to take a selfie after watching the friend’s video and Laughter catcher will call the AI emotion recogniser in the cloud and automatically assign a happiness score based on the facial expression of the user. The daily happiness score will be recorded for big data analytics when the user base grows.With Laughter Catcher, we hope to expand the Laughter Yoga community and encourage people to do the activity anytime and anywhere. This can help spread positive energy and make a change in the community. ‘Spread your laughter, Show your love,’ start smiling today with our app, Laughter Catcher!
