A Real-time Mediated Reality Platform for Outdoor Navigation on Mobile Devices and Wearable Computers

Wearable computing systems have been researched and developed for several decades. With the advent of the head-mounted display, augmented and mediated reality systems became an important example of wearable computing. However, due to certain factors such as computational constraints, cost, obtrusiveness, practicality, and social acceptance, mediated reality systems have been leveraged in only very specific application domains and have yet to see mainstream adoption. This dissertation describes the research and development of a real-time mediated reality platform developed for modern mobile devices to provide a more reasonable transition in overcoming the mainstream adoption barrier of mediated reality systems. In particular, an outdoor navigational application that provides contextually-relevant information about a user’s surroundings is developed using the platform as a proof-of-concept for evaluation. In addition, the server infrastructure required to support the application is discussed, as well as the evaluation of a hybrid orientation tracking approach using sensors and computer vision.MAS
