Security and Privacy For Augmented Reality Systems
Credit: Barry Downard
Augmented Reality (AR) technologies promise to enhance our perception of and interaction with the real world. Unlike virtual reality systems, which replace the real world with a simulated one, AR systems sense properties of the physical world and overlay computer-generated visual, audio, and haptic signals onto real-world feedback in real time. In this article, we consider the security and privacy concerns associated with AR systems themselves as well as those that arise from the supporting technologies.
Researchers have explored the idea of AR since the 1960s, when Ivan Sutherland described a transparent head-mounted display showing three-dimensional information.33 Since the 1990s, AR as a research area has focused on overcoming challenges with display technology, tracking, and registration to properly align virtual and real objects, user interfaces and human factors, auxiliary sensing devices, and the design of novel AR applications.1,2,6,22,36,41
