Much in the same way that a magnifying glass changes the perception of objects under it, we wanted to explore how digital and tangible lenses can be used to interact in the digital world. To give an example, suppose a tabletop presents a user with a friendship graph where the vertices are people and edges represent friendships. We wanted to explore how, for example, a BringNeighboursLens (a lens that would modify the graph to bring the neighbours of the vertices under the lens closer) could be used. We also wanted to explore the differences in a digital lens, a lens in the same plane as the graph, and a tangible lens, a physical object that would be dragged along the surface of the tabletop.
The goals of this project are to answer the following question:
