On the Other Hand
Fabian Hemmert, Gesche Joost · 2016
We describe a presentation system based on the embodied metaphors of giving presentations: topics are picked up, one goes through a series of points, and comes to a conclusion. Technically, our system is based on body tracking and hand-worn RFID readers. Wearing these readers, users can activate topics in live presentations by picking up RFID-tagged mnemonic objects. Each topic can consist of multiple points, which are mapped to positions on stage. Users can activate a point (and its corresponding slide) by walking up to its position on stage. Various actions, triggered by constellations of handheld objects and movements on stage, are supported by the system. We conducted a series of informal user feedback sessions. Its results indicate that our system has strengths and weaknesses, depending on presenter style and presentation context.
