Graphical Representation Of Text Semantics, Karl Kevin Tiba Fossoh
Graphical Representation Of Text Semantics, Karl Kevin Tiba Fossoh
Master of Science in Computer Science Theses
A text is a set of words conveying a particular semantic based on their order, representation and structure. Those elements can be associated through a different set of interpretations, based on frequency and proportionality. The problem with context is that numbers do not help understand the semantics and fall short to convey the message of the text. The graphical representation of text semantics focuses on the conversion of text to images. Contrarily to word clouds that simply produce frequency mapping of words within the text and topic models that essentially give context to word frequencies and proportionalities, images keep intact …
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 …
Towards Understanding And Developing Virtual Environments To Increase Accessibilities For People With Visual Impairments, Miao Dong
Master of Science in Computer Science Theses
The primary goal of this research is to investigate the possibilities of utilizing audio feedback to support effective Human-Computer Interaction Virtual Environments (VEs) without visual feedback for people with Visual Impairments. Efforts have been made to apply virtual reality (VR) technology for training and educational applications for diverse population groups, such as children and stroke patients. Those applications had already shown effects of increasing motivations, providing safer training environments and more training opportunities. However, they are all based on visual feedback. With the head related transfer functions (HRTFs), it is possible to design and develop considerably safer, but diversified training …
