Focus plus context screens are wall-size low-resolution displays with an embedded high-resolution display. Customized software is used to display image content across both display regions, such that the scaling of the image is preserved, while its resolution varies across the two display regions. Content scrolled into the focus region is viewed in higher detail, making the focus display behave like a magic high-resolution lens.
