**6. Conclusion**

This chapter has offered an evaluative perspective on an important aspect in user interphase on game, web, and text. By introducing a novel approach to user interaction and user physiological response, we integrated eye movement and physiological response to determine correlates that serve as tertiary indicators of the stress levels of a user based on attributes obtained from their physiological response. The benefits of the proposed model have proved to be reliable, given the results and findings from the response output of the system and the model has offered some solutions to the persistent user interaction and physiological association, which may be sustainable in the long-term with further evaluations and validations. The method used here provides an automated way of assessing human stress levels when dealing with specific visual contents. This is an important achievement and in that it is able to predict what contents on a visual interphase course stress-induced emotion in users during interaction. This could be applied to other areas like Internet security, triggering alarm for unauthorized access, or abnormal activities online which is the basis for our future work and also in testing performance. This chapter opens the way to possible benefits in terms of predicting human behavior in respect to Internet security by using the process as an alarm trigger for sending alerts on unauthorized access or abnormal activities online; this can be done by detecting user emotion on the visual interphase.
