Title: Ecological Approach to User Interface Design and Evaluation for Augmented Reality Applications
Augmented reality (AR) has the potential to fundamentally change the way we interact with information. Direct perception of computer-generated graphics atop physical reality can afford hands-free access to contextual information on the fly. However, as users must interact with both digital and physical objects simultaneously, yesterday’s approaches to interface design may not be sufficient to support the new way of interaction. Furthermore, the impacts of this novel technology on user experience and performance are not yet fully understood.
This talk will show an example of human factors research on AR for vehicle drivers. I will briefly explain how we (1) designed a novel driver vehicle interface for cross traffic alerts considering not only the user but also the environment, (2) prototyped the design idea for a specific use-case of pedestrian collision warning, and (3) quantified the effects of AR interfaces on driver performance and experience. A series of usability evaluations in both a driving simulator and on a roadway showed that the new interface outperformed the current pedestrian collision warnings in guiding driver attention, increasing situation awareness, and improving task performance. This work has shown the opportunity of incorporating an ecological approach into user interface design and evaluation for AR applications.
