  Some of these quotes stress the fact that the less intelligent prototype interaction was rather short and direct. It should be said that the sequence of the interactions seemed to have some impact on how the participants experienced the interaction. Some participants who first experienced the less intelligent prototype were smiling and positively surprised during this interaction, while others who first experienced the intelligent prototype were over all smiling less while interacting with the less intelligent robot.
  From the interaction with the intelligent version of the robot, some interesting quotes were:

  Some participants clearly expressed how friendly they found the intelligent version of the robot. The sequence of the interactions did not seem to impact their feeling about the interaction as much as with the interaction with the less intelligent version of the robot.
  Some reported that the interaction felt natural and intuitive.
  As for the music, some participants told us that the music did was a useful and pleasant addition to the interaction with the robot.

  From our observations, it seemed as if participants were either smiling more during the interaction with the intelligent version of the robot or concentrating on the interaction more carefully compared to the interaction with the less intelligent version of the robot.

++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.

++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.

++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.
++
++The EVEA and partial Godspeed result can be seen in Figures 3-7 and Tables 1-8. 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. However, in Table 7 we can see that the statistical differences in the mood differences during the interactions with the different versions are not highly significant.
++
++A Wilcoxon signed rank test for the partial Godspeed test shows in Table 8 that with high confidence (1% confidence limit), the intelligent robot is more likeable in comparison to the simple robot. With these results it is likely that the more advanced robot is slightly preferrable and the personas might experience less negative emotions after the interaction with the robots, but it is slightly unclear if the effect is more powerful with the advanced robot.

  Analysis the results surfaced some minor issues in the experiment, such as the lack of comparison with two robots of similar features, with and without music. Also the practical limitations in the setup, such as the lack of different food options and some participants being aware of the design goals of the prototype could have interfered with the natural flow of the intercourse. With these limitations, the research method was successful in extracting differences within the robots and brought up additional directions for future research.
  The most interesting direction for future research would be the longer term studying of the effect of mealtime reminders on the health of the test subjects. The longer term health study would uncover the effect on eating frequency and the development of the relationship with the robot, for example would the test subjects that were first excited about the novel interaction with the robot, develop negative feelings about the supervision that the robot is conducting into their personal life.
