Bayer Corporation looked for technological upgrades to increase production. We proposed MPEG technology on video transmission over wireless networks to Bayer. To complete our task, we searched for mobile video communication technology. We identified that mobile phones with built-in cameras addressed Bayer's problem. A project was set-up to choose the right product for Bayer. Three competitive camera phone models, Sony Ericsson P800, Samsung SGH-V205, LG VX6000, were selected as test candidates. A mobile phone usability test was performed in five stages to test the quality of three selected models. In the first stages, two test locations were chosen. In the second stage, a usability test lab was set-up. In the third stage, 15 evaluators and 3 observers were selected, and a questionnaire related to the usability test was prepared. In the fourth stage, usability evaluations were conducted. In the fifth stage, test findings were documented. The usability test results indicated that Sony Ericsson P800 was not easy to navigate from task to task, Samsung SGH-V205 had the best voice quality, and LG VX6000 was equipped with Global Positioning System. After the results were analyzed, we concluded that Samsung SGH-V205 was the best model among the three selected models.
