Description: Two layer displays are constructed by overlaying one transparent flat panel on another, with a discernable physical separation between layers. This layout could enhance depth perception and increase the available pixels without increasing the width and height of the display. However, it is unclear if the second physical layer provides any advantage over simple alpha-blended transparency on a single layer display. We investigate this issue in two controlled experiments that compare performance between one and two layer displays in focused and divided attention tasks. Results show that for spatially overlapping objects, performance in a focused attention task is similar for both displays, while performance in a divided attention task is degraded on two layer displays. For spatially non-overlapping objects, performance in a focused attention task is degraded on the two layer display if a distractor object is placed on the front layer. Implications for user interface design are also discussed.
