258 +The hypothesis H0 is that Pepper does not have any effect. In this case, the questionnaires 1 and 2 should give the exact same values for each of the six feelings. However, the graphs and table below show that there is a slight increase regarding positive feelings, and a sligt decrease as well regarding negative feelings.
259 +There are however many biases in these results. The main one that we isolated is that the activity of gardening itself could lead to the mood improvement. For this reason, we made subgroups based on whether the participants liked gardening or not.

558 -Since each PwD has its own state of dementia and personal issues, it is very difficult to get uniform results, especially since they are collected orally.
559 -Getting very nice, fully robust and reliable results, is merely a hope and a dream.
560 -However, we can try to consider the main trends that we are interested in.
561 -Thus, the results wil be mainly focused on:
562 -- How much autonomy did the PwD gain?
563 -→ what did the HCP, relatives and PwD report
564 -→ how many tasks did they perform that they didn't do previously
565 -→ did the relatives feel they had more time for themselves
566 -- Did their emotional state improve?
567 -→ feelings from the PwD themselves
568 -→ reports from relatives and HCP
569 -These results will most likely never be yes-no results, but more like clues or hints that show whether some things worked on not, which will be the point of our discussion.
570 -NB: This part explains what we expect as kind of results, it will be replaced by actual results after we perform an experiment with the class. There may also be interesting points we did not think about.

577 577  * Scope: No. It would be very difficult to generalize the results, since each prototype is built for a special patient. However, if the results conclude that the customized prototypes did improve the well-being of the people, then similar effort to customize Pepper for more patients should produce similar effects.
578 578  * Ecological validity: Yes. Since we compare "without Pepper" (BEFORE) and "with Pepper" (AFTER) in a similar environment (i.e., for everything but Pepper), the results are not dependent on the environment.
579 579  
575 +We analyzed the participants' moods before and after the interaction with Pepper in order to be able to observe positive and negative changes that are caused by pepper. the results showed that, in general, there is a slight increase in positive moods and a slight decrease in negative moods. The Wilcoxon Signed-rank demonstrated that the only statistically significant change happened for contentness and tiredness based on a p-value threshold of 0.05. This confirms that PwD can potentially benefit from a boost of energy from interacting with Pepper and a general improvement in contentness wich can potentially improve the quality of life of a PwD. It is often the case that PwDs have to perform tasks that are not enjoyable for them such as taking medicines or performing routine activities. In order to analyze the difference in the mood change between people who liked the activity and people who didn't we divided into two groups and performed a Wilcoxon Rank-Sum test. The results show that only the contentness mood shows a statistically significant difference between the two groups which leads us to believe that if an activity is not enjoyable for the PwD Pepper will only decrease his/her tiredness whereas if an activity is enjoyable it will also improve his/her contentness.

580 580  == Conclusions ==
578 +
579 +The results from the mood questionnaire seem to support our claims CL10: the PwD feels reassured and CL11: the PwD feels content.
580 +Although there are many potential biases, there seems to be a general trend which is that the mood of the participants slightly improved thanks to the activity.
581 +
582 +All participants, except one who asked to leave the experiment early, finished the whole activity we had prepared for them during the session. This means the participants were able to perform activity steps told by Pepper. This supports our claim CL03: the PwD performs an activity step.
583 +
584 +No participant failed to notice Pepper or did not hear what she was saying after the experiment had started. This supports our claim CL01: the PwD becomes aware of Pepper's presence.
585 +
586 +From the system assessment questionnaire, participants quite agree that completing the task was a good accomplishment for them. This supports our claim CL08: the PwD feels accomplished.
587 +
588 +We did not have any question explictly aimed at targeting our claim CL08. However, frustration, annoyance and pressure are often linked to a lack of understanding from the other part. We can combine these with the question about whether Pepper cared about helping the participants, and with our observations during the experiment. When aggregated together, it seems that generally speaking, the participants felt understood. This supports our claim CL08: the PwD feels understood. However, we did notice frustration a couple of times from the participants, because of Pepper's speech recognition system.
