"Wearable augmented reality medical" (WARM) interfaces may be central to a future generation of point-of-care clinical decision support systems. Interface metaphor creation and validation are critical tasks at this stage of development [33, 39]. Applications built from these new interface objects must be shown to provide functionality that previously was unavailable or to markedly enhance functionality that already is [40].
Our current efforts constitute preliminary work in this direction. Our results confirm that reduction of perceptual separation of simultaneous tasks can speed decision performance, though this enhancement is subject to visual clutter limitations. Three-dimensional representations of medical information are difficult to design and must be carefully evaluated for efficacy.
