Abstract
This research is an examination of the concept of process semantics representing the meaning of tasks, time, space, and navigation. In assessment of this concept, children were tested with an existing typical office mail application comparing the mailman program with the Process semantics. The office mail was the regular mail used in commercial software, while the mailman was designed for hypothesis testing. Sixty subjects did the usability testing of six tasks. When interacting with both programs, the completion times of three tasks in mailman program are faster than those in the office mail. Moreover, the number of errors with the mailman program is less than that with the office mail for all tasks. The result reflected the process semantics with the operational transparency in conjunction with the metaphor of mailman agent significantly improving children’s understanding.
