213 213  From the results we can see that the more advanced robot shows advantages over the simple version in many categories. Hints of better performance in other categories can be seen, but no conclusions should be drawn from the ones that lack the statistical significance.

215 -In improving the eating, it seems that both robots have limited success in causing the people to eat as seen in Figure 1, they could cause the patients to eat more regularly, if triggered by timers or other suitable systems. It also seems that the advanced robot is better in the reminding, by a slight margin. However, the long term effects of reminding should be researched more to conclude whether the usage of the demonstrated robot platform or similar would cause the patients to eat more regularly. It is also unclear how the test setup and the limited choice of food affected the eating.

217 -Based on the answers of the participants regarding music seen in Figure 2, it seems that most of them were either indifferent or liked the music. Also, as the test personnel find the advanced robot more likeable with a 5% confidence limit (Table 7), and the advanced version was the only version with music, it seems likely that the music does make the interaction more pleasant for the personas. However, some of the likeability might be due to the other advanced features of the robot and thus more research is needed to conclude the effect of the music.

219 -The EVEA and partial Godspeed result can be seen in Figures 3-7 and Tables 1-7. The results show that with reasonable confidence (5% confidence limit), both versions of the robot decreased sadness and anxiety in the test personas. Hints are shown (10% confidence limit) that the advanced robot also decreases feelings of anger and increases happiness, while the simple robot fails to show similar results. A Wilcoxon signed rank test for the partial Godspeed test shows that with high confidence (1% confidence limit), the intelligent robot is more likeable in comparison to the simple robot.
