When the new prototype was ready a seond user evaluation was performed. This time the prototype was tested by 100 voluntary test users and the User Evaluation was carried out in Austria (Vienna: 7 users, Linz: 7 users, Axams: 10 users, Schwechatbach: 1 user) Germany (Volmarstein: 20 users, Berlin: 5 users, Bremen: 5 users), Belgium (Namur: 15 users, Mons: 10 users) and Sweden (Uppsala: 20 user) supported by all test sites involved in the project.
The test users recieved FASTY for six weeks, starting in January 2004, and used FASTY for their every-day typing and communication tasks. The tests started with version 2.00.00 and were continued with the subsequent releases of the FASTY prototype.
All relevant events, such as keystrokes made by the user, selection events, changes in parameter settings etc. were written to a log file. The result of the evaluation was partly based on these log files and partly on a questionnaire that the users were asked to fill in. The questionnaire was presented to the users as a Poll Tool. The electronic version of the form-sheets enables even severely impaired persons and those voluntary users outside the test-sites of the project to fill in the report form independently, without being influenced by the developers.
During the verification phase, a special password protected web site was provided, to give users and the user partners the possibility to retrieve the latest full versions and patches of PT2. A Discussion Board was also established for the users to discuss with other users about FASTY.
The log files were calculated using the keystroke saving rate (KSR) formula. KSR is the percentage number of keystrokes that a user saves by using a word predictor to type, compared to the total number of keystrokes that are required to generate the same text without a predictor.
