Existing System (Workrave)
Our System (Kinexercise)
User study conditions
• It is a 30 person user study
• 15 people used Kinexercise and other 15 used Workrave.
Feasibility is why we had to keep this system.
• The duration was over one work week.
To see the effects of exercise over a relatively long period.
• They had to run the system on start-up.
To keep an accurate log of # of exercises done (or not done).

Conclusion
• Based on the p-values and t-values obtained, we can safely
reject the null hypothesis for both, the primary and secondary
hypothesis.
• This proves that our system makes the users do more
exercises compared to the current system.
• The secondary hypothesis helps prove that, for the current set
of users, our system ranked higher in satisfying the users.
