Old theories, new technologies: cumulative clutter effects using augmented reality

The paper investigates human cognitive performance when information is presented via augmented reality (AR) and overlaid upon a primary display. Initial results support traditional experimental paradigms of human memory (G.A. Miller, 1956) and comprehension of information (C.D. Wickens, 1992), and have been used to compare AR and standard display formats when used in isolation. Results from these experiments provide a fundamental baseline for cognitive performance with a see-through AR headset. Furthermore the results lay the foundations for more comprehensive trials later in the research programme when the display formats are combined to provide a full AR facility. Consideration is given to the specific effects of cumulative clutter and two experiments are outlined that investigate the effects on target identification. Although the data are still being analysed, further consideration is given to key points addressed in the experimental design. Details of a dedicated Web site are provided where information will be consolidated and provide a basis for developing guidelines for the future development and application of AR technology
