Loughborough University is a top-ten rated university in England for research intensity (REF2014) and an outstanding 66% of the work of Loughborough’s academic staff who were eligible to be submitted to the REF was judged as ‘world-leading’ or ‘internationally excellent’, compared to a national average figure of 43%. In choosing Loughborough for your research, you’ll work alongside academics who are leaders in their field. You will benefit from comprehensive support and guidance from our Doctoral College, including tailored careers advice, to help you succeed in your research and future career. This PhD is concerned with developing new techniques to improve the accuracy of augmented reality (AR) in engineering applications. In current AR applications, special markers are placed in the real-world and recognised through image processing techniques to place computer generated text or graphics over the real-world. Unfortunately, the real-world - virtual-world interface is not very accurate. This PhD project is concerned with developing new techniques that will enable space stabilised, accurately scaled and located AR engineering data to be displayed with respect to the real-world. In this application we are assuming the use of tablet computer based AR where the camera on the tablet computer is used to capture the real-world in conjunction with the spatial markers. We anticipate that new spatial markers will be developed by the research so that they contain additional information such as links to relevant contextual engineering data. The research will involve investigating the science behind AR from a technology and human factors perspective to achieve the required level of accuracy.
