A Low Cost Adaptive Graphical User Interface For The Visually Handicapped With Multiple Conditions, David Veal, Stanislaw Maj
A Low Cost Adaptive Graphical User Interface For The Visually Handicapped With Multiple Conditions, David Veal, Stanislaw Maj
Research outputs 2011
Limited trials have been demonstrated that a Graphical User Interface (GUI) for the visually handicapped called Dynamic Pattern System (DPS) can adaptively utilize residual vision by generating different patterns, colors and shapes. Low vision simulators, used by normally sighted, have allowed researchers to clearly identify visual impairments that can be helped by DPS. However, it is not uncommon for the visually handicapped to suffer from multiple conditions having a multiplicative degenerative effect on their sight. This paper demonstrates how DPS can be used to assist individuals with compound sight disorders.

A Linux-Based Graphical User Interface For The Creation And Reading Of The Frame Format: Version 2.4, Muhammed Aoun
A Linux-Based Graphical User Interface For The Creation And Reading Of The Frame Format: Version 2.4, Muhammed Aoun
Theses : Honours
To gain further knowledge of how the universe began, a new international co-operated project wishes not only to "see" stars exploding, but also to "hear" the explosion. It is theorised that the ability to "listen" to an explosion is possible by detecting gravitational waves. Gravitational waves are omitted when a star explodes, travelling through the cosmos at an exceptional speed. It is estimated that a gravity wave takes only 40 milliseconds to pass through the earth. Thus the aim of this international collaboration is to detect a gravitational wave. To accurately detect such waves, there needs to be several global …

The Design Of 3d Cyberspace As User Interface: Advantages And Limitations, Maria Borisovna Quick
Theses : Honours
Virtual reality propagandists, technologists and the Internet community have long debated the issue of the usability of online three-dimensional (3D) environments. A lot of work was published about the benefits of 3D spaces for human-computer interaction and information visualisation due to their realism (Anders, Kalawsky, Crossley, Davies, McGrath, Rejman-Greene, 1998, Hamit, 1993, Heim, 1992, Aukstakalnis, Blatner, Roth, 1992). This topic also receives continuous industry support including standardisation of Virtual Reality Modeling Language ( VRML, VRML Consortium, 1997) and the more recent Macromedia & Intel alliance "to bring web 3D to the mainstream" (200 1, Intel Corporation). The actual implementation …
Storage Free Terrain Simulation, Warren Creemers
Storage Free Terrain Simulation, Warren Creemers
Theses : Honours
Landscape visualisation is the process of recreating a natural environment and displaying it in an interactive graphical simulation. To do this a terrain is displayed together with accompanying plant life and other objects. Present landscape visualisation software is capable in theory of displaying very detailed and large landscapes. The software is also in theory capable of simulating environments with thousands if not millions of individually structured plants. In practice though, the simulation of such landscapes requires such a large amount of storage space that it is not achievable on personal computers. Even storing small landscapes with a moderate amount plant …
Virtual Reality And The Modern Ideology Of Order And Control, Craig I. Murrihy
Virtual Reality And The Modern Ideology Of Order And Control, Craig I. Murrihy
Theses : Honours
In this thesis I will examine the construction of the concept of Virtual Reality. I argue that rather than a technology of liberation as it is often perceived, virtual realities' conception has been influenced significantly by a discourse of control and order. I examine books, articles and films concerning Virtual Reality to support this claim. Furthermore this discourse of control and order is born out of a larger ideology of Western culture that values order and control. Throughout modernity this ideology has manifested itself through techniques and technologies of social and environmental control. I provide a brief historical outline highlighting …

An Approach To Display Layout Of Dynamic Windows, Nihar Trivedi
Theses: Doctorates and Masters
The development of windows based user interface has introduced a new dimension to the field of human computer interaction. Now a user is able to perform multiple tasks at a time, often switching from one task to another. However windows environment also imposes the burden of manual windows management on the user. Several studies have suggested that manual window management is an unproductive chore often resulting in clutter and confusion on the display screen. Therefore we need a automatic windows layout generator to free the user to perform other useful tasks. This thesis introduces SPORDAC {Shadow Propagation for Overlap Removal …
Arbitrary Views Of High-Dimensional Space And Data, Andrew Ellerton
Arbitrary Views Of High-Dimensional Space And Data, Andrew Ellerton
Theses : Honours
Computer generated images of three dimensional scenes objects are the result of parallel/perspective projections of the objects onto a two dimensional plane. The computational techniques may be extended to project n-dimensional hyperobjects onto (n-1) dimensions, for n > 3. Projection to one less dimension may be applied recursively for data of any high dimension until that data is two-dimensional, when it may be directed to a computer screen or to some other two-dimensional output device. Arbitrary specification of eye location, target location, field-of-view angles and other parameters provide flexibility, so that data may be viewed-and hence perceived-in previously unavailable ways. However, …
