Virtual Reality As Navigation Tool: Creating Interactive Environments For Individuals With Visual Impairments, Nick Murphy
Virtual Reality As Navigation Tool: Creating Interactive Environments For Individuals With Visual Impairments, Nick Murphy
Master of Science in Computer Science Theses
Research into the creation of assistive technologies is increasingly incorporating the use of virtual reality experiments. One area of application is as an orientation and mobility assistance tool for people with visual impairments. Some of the challenges are developing useful knowledge of the user’s surroundings and effectively conveying that information to the user. This thesis examines the feasibility of using virtual environments conveyed via auditory feedback as part of an autonomous mobility assistance system. Two separate experiments were conducted to study key aspects of a potential system: navigation assistance and map generation. The results of this research include mesh models …

Real-Time Object Removal In Augmented Reality, Tyler Dahl
Master's Theses
Diminished reality, as a sub-topic of augmented reality where digital information is overlaid on an environment, is the perceived removal of an object from an environment. Previous approaches to diminished reality used digital replacement techniques, inpainting, and multi-view homographies. However, few used a virtual representation of the real environment, limiting their domains to planar environments.
This thesis provides a framework to achieve real-time diminished reality on an augmented reality headset. Using state-of-the-art hardware, we combine a virtual representation of the real environment with inpainting to remove existing objects from complex environments.
Our work is found to be competitive with previous …
