Abstract
Digital signage has been used for services such as advertisement and guidance in public spaces. The use of interactive digital signage has been increasing in recent years. To make full use of the interactivity of digital signage, it is necessary for people to start to interact. In this study, we made a hypothesis that fluffy objects have attraction affordance, and aimed to verify this hypothesis by developing a fluffy screen system. The proposed system is inflated with air. Then, multiple touch inputs from the outside of the screen are detected by cameras inside the screen, and clustering is performed. The information is presented by LCD projectors based on the results of clustering. A field trial in a shopping mall was conducted to verify the hypothesis. A very high interaction rate was realized during the trial of four hours. The results strongly support the hypothesis.
