An Egocentric Augmented Reality Interface for Spatial Information Management in Crisis Response Situations

摘要

In emergency operations centers, operators are challenged with managing and analyzing massive amounts of information in a timely manner. With the advent of motion tracking systems and low-cost, high-performance graphics workstations, novel spatial augmented reality (AR) interfaces are becoming technologically feasible. AR interfaces have very unique characteristics as compared to other media and computer interfaces: users interact with the computer system through body motion in a volumetric space, instead of via a two-dimensional surface. We have created three prototype immersive AR computing interfaces for emergency operation center. User interacts with the information using a pair of motion tracked pinch gloves, and information is displayed through a head-tracked optical see-though head mounted display. The emergency operator uses intuitive grab and release gesture to move and manipulate the digital information in the environment analogous to interaction of everyday life objects.
