A Conceptual Framework for Camera Phone-Based Interaction Techniques
This paper proposes and evaluates interaction techniques for camera-equipped mobile phones. The proposed techniques are based on a visual code system that provides a number of orientation parameters, such as target pointing, rotation, tilting, distance, and relative movement. Our conceptual framework defines a set of fundamental physical gestures that form a basic vocabulary for describing interaction when using mobile phones capable of reading visual codes. These interaction primitives can be combined to create more complex and expressive interactions. A stateless interaction model allows for specifying interaction sequences, which guide the user with iconic and auditory cues. In using the parameters of the visual code system as a means of input, our framework enhances the currently limited input capabilities of mobile phones. Moreover, it enables users to interact with real-world objects in their current environment. We present an XML-based specification language for this model, a ...
