Using Augmented Reality for Training Computer Workstation Ergonomic Issues: An Exploratory Project

The number of hours dedicated to working at a desk and in front of a computer is gradually taking its toll on millions of people. It has drastically increased the number of health issues associated with this study and work habits. The ATOMIC project, presented in this paper, explores the use of Virtual Reality and Augmented Reality solutions for training and teaching activities in a diverse array of contexts, such as creating awareness of computer workstation inherent ergonomic issues. The prototype presented is closely concerned with training its users to recognize their poor decisions regarding their desk workstation organization and helping to improve their decisions and behaviour in this context. It includes an augmented reality solution projected onto the desktop, capturing information with a standard webcam, a computer vision solution using OpenCV and Python, or a QR code solution through Unity and Vuforia. The prototype was evaluated during a summer school with the participation of 20 higher education students during a 4-stage test protocol (profiling, pre-test, AR experience, post-test) during which data regarding the user experience and interface usability was collected through 3 questionnaires all answered through an app on the users’ smartphone. The results attained were, in general, positive and showed that the users comprehended the purpose of the application and regarded it as useful for further understanding the benefits of small adjustments in their workstation layouts. Although they did not feel immersed in the experience, the users did see using the application as a better method for learning about ergonomic issues as opposed to more traditional pen-and-paper approaches. Overall, the tests conducted provided a detailed insight into the pertinence of the prototype and its context, as well as a list of suggestions for further improvements regarding its UX strengths and weaknesses.
