Science Birds Gameplay With a Smile Interface to Promote the Spectator’s Emotion

This demo paper presents a smile interface to promote the spectator’s emotion. Here, a smile interface is defined as a human-computer interaction system that detects the user’s smile. A past study suggested that watching Science Birds gameplay featuring Rube Goldberg Machine mechanisms with a domino effect can promote the spectator’s emotion. Science Birds is a clone version of Angry Birds for research purposes. Furthermore, other studies suggested that playing Science Birds with a smile interface has the benefit of promoting the player’s emotion. However, such benefit from the spectator’s perspective is yet to be investigated. The presented interface will be used in such investigation in the future.
