The study was designed to identify how home computers were being used by 200 selected home computer owners living in Richmond, Virginia. The 1984 study identified the expressed problems these owners experienced using home computers and determined what changes or information the owners believed were needed to use the computer more effectively. The most commonly used home computer applications were personal word processing, entertainment, and work related word processing. Many home computer owners indicated that no factor had prevented them from using their computer. Those indicating that some factor had prevented their use, reported the high cost of software, the lack of useful software, and unclear or incorrect instructions presented problems. Males were much more likely than females to be the principal computer user. Consistent with Rogers (1983) diffusion theory, most computer owners did use personal sources during their prepurchase information search. Statistically significant differences existed between the owners satisfaction with hardware and the number of products and services used and between overall satisfaction and the amount spent on software. Significant inverse relationships indicated that those respondents who spent less on hardware and had less random access memory had higher levels of overall satisfaction than those who spent more on hardware and had more random access memory. Recommendations included methods of individualizing service and assistance for owners after the purchase. / Master of Science

The convergence between personal computer-based games and virtual environments technologies dramatically reduced development costs and potentially increased the use of the technology in training activities. Using open source/free software tools in the process can expand these possibilities, resulting in even greater cost reduction and allowing the flexibility needed in a training environment. This thesis presents a configuration and architecture to be used when developing training visual simulations using both personal computers and open source tools. Aspects of the requirements needed in a visual simulation development, processes to develop an application and issues related to the use, licensing and selection of open source/free software are analyzed to identify their limitations and possibilities. This architecture was tested by developing a small visual simulation. The tools and engine used are presented to enable any future project applying open source software to follow similar procedures.
