## Results And Discussion

Error frequencies Figures 3 and 4 show the participants clicks against the time for solvers and non-solvers, correspondingly. These data say of what was the speed of clicking in the course of work with the program. To compare, every figure contains a straight line the slope of which characterizes an average clicking speed for the overall time of work.

Fig. 3. Sequence number of clicks plotted against time when the clicks were done by solvers. The straight lines characterize the average speed of clicking.
