	222	+== Qualitative Results: Quotes and observations ==
	223	+As described, during the experiment, the interaction between the participants and the robot was observed. This section will elaborate on findings from those observations and quotes from participants.
	224	+
	225	+After each interaction section, the the participant was asked how the interaction with the robot felt. From the interaction with the less intelligent version of the robot, some interesting quotes were:
	226	+* “The robot was bit direct.”
	227	+* “Efficient interaction, but less friendly than the other interaction.”
	228	+* “Strange, I did not catch the questions.”
	229	+* “It felt short.”
	230	+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.

	232	+From the interaction with the intelligent version of the robot, some interesting quotes were:
	233	+* “I think it’s perfect, the robot is very friendly. I liked that the robot sat down with me after a while.”
	234	+* “The interaction felt quite natural.”
	235	+* “Nao answered pretty quickly, you don’t have to wait for an answer. It is quite a happy robot.”
	236	+* “Suggestion to eat was still a bit on the side, a little subtle if I would have dementia.”
	237	+* “Very nice, calming, I could have stayed longer with the music.”
	238	+* “It was good, natural, understands what I’m saying.”
	239	+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.
	240	+Some reported that the interaction felt natural and intuitive.
	241	+As for the music, some participants told us that the music did was a useful and pleasant addition to the interaction with the robot.
	242	+As for the suggestion to eat and drink, one participant reported that the suggestions to eat and drink were perhaps too friendly and too subtle.
	243	+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.

223	223	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.

227	227	Another topic to study is the differences with and without music. The effects of music could be studied with the music tailored to personal taste and all versions of the robot with and without the music playback included in the interaction. This would allow to pinpoint the effects of music, without the other features causing variance.

	252	+Lastly, the observations and interviews with the participants clearly demonstrated that for now, that a more friendly and intelligent robot does make the interaction with the robot more pleasant.

230	230
231	231	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.
