Spatial information displays on a wearable computer

Increasing portability of computing power marks a broad emerging trend in advanced human-computer interaction. Wearable computers, the next generation of portable machines, worn on the body, provide constant access to computing and communications resources. However, wide adoption of wearable computers first requires solving unique interface challenges. One of the most important is how to present and interact with information in a wearable environment. We designed and evaluated three methods for presenting information in a wearable environment. Subjects found spatial displays easier and more effective. Spatial audio and visual cues further enhanced performance
