Query by attention: visually searchable information maps

This paper explores how the design of information spaces might be grounded in knowledge of human visual processing, notably what kinds of visual selection are most efficient. Information maps spatially array graphical symbols representing items of information and their attributes. Ideally their users should be able to do query by attention: answer questions about the information quickly by controlling visual attention (i.e., through spatial selection and visual search), instead of manipulating an interface. I propose a preliminary method for designing visually searchable maps based on experimental results about what kinds of visual search are easy. The hope is that the resulting maps will better employ the perceptual capabilities of their viewers when they search. An example information map of recent movies illustrates the approach
