6 Result and Evaluation
To evaluate the use of FT measurements as a diagnostic tool for stress, a computer
based prototype system has been built and tested.
A user can select different matching algorithms and see the detailed information
for a new case compared to an old case. Fig. 23 displays a screen shot which shows
similarity matching of a current case with the previous cases in a ranked list. The
system identifies the current case with the reliability of 71.8% that the subject is under
the state 'very_stressed'.
Fig. 23.
Similarity matching of a current case with previous cases is presented in a ranked list
of cases as solution.
