Through-the-Display Interaction in Het- erogeneous Multi-Display Environments

With the introduction of mobile devices as well as large public displays, we are surrounded by multiple devices at nearly all times throughout the day. However, these devices are extremely heterogeneous regarding their input and output capabilities making it hard to seamlessly interact between them. In my dissertation work I explore novel interaction techniques that leverage the advantages of both mobile and stationary displays. I investigated existing techniques that allow copying, moving or manipulating information across multiple displays by paying attention to heterogeneity. Based on the results, I propose a design space and created a set of tools for multi-display interaction. I propose a form of interaction called “superimposed displays” which works for both reachable and unreachable displays.
