||Buildings and public infrastructures are crucial to our societies in that they provide habitations, workplaces, commodities and services indispensable to our daily life. As vital parts of facility management, operations and maintenance (O&M) ensure a facility to continuously function as intended, which take up the longest time in a facility’s life cycle and demand great expense. Therefore, computers and information technology have been actively adopted to automate traditional maintenance methods and processes, making O&M faster and more reliable.
Augmented reality (AR) offers a new approach towards human-computer interaction through directly displaying information related to real objects that people are currently perceiving. People’s sensory perceptions are enhanced (augmented) with information of interest naturally without deliberately turning to computers. Hence, AR has been proved to be able to further improve O&M task performance.
In the first part of this presentation, I will introduce AR and its enabling technologies while the second part will be concerned with my research on user evaluations of AR applications in the context of facility maintenance. The focus is to examine user task performance, which is influenced by both AR system performance and human perceptive, cognitive and motoric factors.
