A Systems Approach for Augmented Reality Design
Effective ways of presenting digital data are needed to augment a user’s experience in the real world without distracting or overloading them. We propose a system of systems approach for the design, development, and evaluation of information presentation devices, particularly augmented reality devices. We developed an evaluation environment that enables the synchronized presentation of multimodal stimuli and collection of user responses in an immersive environment. We leveraged visual, audio, thermal, and tactile information presentation modalities during a navigation and threat identification task. Twelve participants completed the task while response time and accuracy data were collected. Results indicated variability among devices and pairs of devices, and suggested that information presented by some pairs of devices was more effective and easily acted upon than that presented by others. The results of this work provided important guidance regarding future design decisions and suggest the utility of our system of systems approach. Implications and future directions are discussed.
