Camera-based mobile interaction techniques for physical objects
Niels Henze, Susanne Boll · 2012
A number of mobile applications enable users to take photos of physical objects to receive related information and services. Commercial implementations such as Google Goggles use a Point & Shoot interaction technique that requires to explicitly taking a photo to trigger the object recognition. In this paper we investigate alternative interaction techniques to receive information about physical objects. For the study we try to rule out all aspects but the basic interaction. We compare Point & Shoot with two other techniques to access information about music CDs and show that using handheld Augmented Reality is preferred by users and leads to a lower perceived task load. Our findings confirm that research and development effort towards handheld Augmented Reality is well invested.
