Adding context information to digital photos

In a user centered design process, we investigate what context information may be used to augment digital photos with additional meta information. We describe our initial findings from user interviews and present the design and implementation of a prototype that is used to carry out studies with users. The basic prototype is a sensor box attached to a digital camera mounted beneath the camera instead of a tripod and wirelessly connected to a wearable computer. In a study with three professional photographers and two hobbyists we could show the feasibility of this approach. Based on the results gained we suggest potential improvements for digital photography.
