In this talk, I will present Focus plus context screens. Focus plus context screens are wall-size low-resolution displays with an embedded high-resolution display region. Image content is displayed such that the scaling of the display content is preserved, while its resolution varies according to which display region it is displayed in. Focus plus context screens allow users to view details of a document up close, while simultaneously seeing peripheral parts of the document in lower resolution. I will present our prototype that seamlessly integrates an LCD with a projection screen, demonstrate four application scenarios, and report the results of an experimental comparison with competing visualization techniques.
