Real-Time Human Cognition of Nearby Vibrations Using Augmented Reality

Abstract

Human-computer interaction is an important part of structural monitoring and the research community is interested in amplifying human cognition of structural response. Augmenting feedback closes the loop between reality and human, where normally the human would need to check a computer or other separate screen for information on the real-time structural response. The research proposes using an Augmented Reality (AR) application to provide inspectors with realtime information about structural responses, to allow the user to perceive real-time changes. The proposed research seeks to validate the AR application as a useful tool in the field. This paper presents the results of an experiment that show how AR can provide a channel for direct sensor feedback. The application displays a live graph of accelerometer data with a low delay close to real time. The results of the reported experiment prove the usefulness of the AR application in the field by comparing feedback delay over a local area network versus a mobile WiFi hotspot.

Reducing gaze distraction for real‐time vibration monitoring using augmented reality

“…The Serial Monitor window begins auto-scrolling with the three columns of acceleration data once a client successfully connects. A limitation of the application is a slight time delay in the augmented plot of sensor data induced by the network connection, which was investigated and found to be 0.26 s. 34 The tests were conducted on a mobile hotspot which is used as the WiFi network for the experiment section of this paper. This limitation is considered when reviewing results.…”
