Computer scientists must align social and technical factors for communication technologies in developing regions yet lack a framework to do so. The novel Softbridge framework comprises several components to address this ...

When moving through an environment, people unconsciously build up a mental image, or cognitive map, of that environment. When later planning a trip or giving directions to someone else, they can mentally walk through the ...

Many virtual environments like interactive computer games, educational software or training simulations make use of speech to convey important information to the user. These applications typically present a combination of ...

The efficiency of an image compression/synthesis system based on a spline multi-resolution analysis (MRA) is investigated. The proposed system uses a quadratic spline wavelet transform combined with minimum-mean squared ...

This dissertation explores virtual storytelling for conveying cultural stories effectively. We set out to investigate: (1) the strengths and/or weaknesses of VR as a storytelling medium; (2) the use of a culturally familiar ...

This dissertation reports on the results on an exploratory investigation into the potential efficacy of VR as both a support mechanism to people living with HIV I AIDS, as well its capabilities as an emotive medium. Two ...

Intermediaries are necessary to overcome challenges of Internet use for many users in the developing world. However the need for co-presence with intermediaries can be inconvenient for beneficiaries, and the process is ...

Information and Communication Technologies (ICTs) in general, and mobile phones in particular, have demonstrated positive outcomes in the various social transformation and human development dimensions. As a result, many ...

This project aims to find the minimum video resolution and frame rate that supports intelligible cell phone based video communications in South African Sign Language.

ATM and dynamic reconfiguration allow for rapid changes in a virtual path network depending on traffic load and future demands. This technology improves the utilisation, lowers the call blocking probability and increases ...

For any technology to become widely-used and accepted, it must support end-user authoring and customisation. This means making the technology accessible by enabling understanding of its design issues and reducing its ...
