New Interface Metaphors for Complex Information Space Visualization: an ECG Monitor Object Prototype

Abstract

Wearable augmented reality medical (WARM) interfaces could provide ubiquitous point-ofcare decision support and enhance the quality and efficiency of clinicians' efforts. Creation of such systems involves the design and evaluation of new information displays that leverage the representational and presentational capabilities of three-dimensional AR environments. We describe our first efforts in this process: the implementation of interface objects for display of real-time electrocardiographic monitoring information and an evaluation methodology using a simulated clinical environment. Our pilot data confirm the utility of presentation modes that place simultaneous information tasks in close proximity, and highlight issues encountered in designing new representations of medical information. 1. Introduction In caring for patients, clinicians must rapidly and accurately integrate large, complex and variable sets of information---including patient-specific data, general medical knowledge an..
