++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.
++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.

++This graph shows that the trust in Pepper was highly dependent on whether the participants enjoyed the activity or not.

--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.
--Getting very nice, fully robust and reliable results, is merely a hope and a dream.
--However, we can try to consider the main trends that we are interested in.
--Thus, the results wil be mainly focused on:
--- How much autonomy did the PwD gain?
--→ what did the HCP, relatives and PwD report
--→ how many tasks did they perform that they didn't do previously
--→ did the relatives feel they had more time for themselves
--- Did their emotional state improve?
--→ feelings from the PwD themselves
--→ reports from relatives and HCP
--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.
--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.

  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.
  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.

++The results from the mood questionnaire seem to support our claims CL10: the PwD feels reassured and CL11: the PwD feels content.
++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.
++
++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.
++
++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.
