Magic lenses are popular tools to provide locally altered views of visual data. In this project, we introduce the concept of BodyLenses, special kinds of magic lenses for wall displays that are mainly controlled by body interactions. We present a comprehensive design space and investigated a number of design alternatives proposing solutions for lens positioning, dynamic shape modification, distance-based parameter mappings and the use of BodyLenses as portable tool belts. We demonstrate the practicality of our novel concepts with four realised application scenarios and lay the foundation for future research and systems based on body-driven lenses.
Design Space
We define the term BodyLens as any type of personal, body-controlled magic lens used on a vertical display. Thus, the magic lens can apply any function to a user-centred region of interest, including selection, zooming, focus+context, advanced visual modifications, or semantic changes to the data. “Body-controlled” refers to a) any type of body movement with regard to the fixed display as well as b) gestures of any body part — most prominently arms and hands, but also head, legs and feet — and any combinations thereof. Furthermore, provided the display is an interactive surface, c) direct interaction on the display is also possible, e.g. by means of multi-touch, pen or tangible input. While horizontal movements along the wall display typically influence the position of the lens, distal movements, body gestures and direct interactions may influence any other parameter associated with the lens.
In our design space, we focus on
- the appearance of the lenses,
- their magic lens function,
- possible interactions to influence position, shape, and function, and
- their use in multi-user contexts.
