80 -As one can see, the results were not exactly significant. The only question that obtained a reasonable p-score (P=0.022) was Q14. This implies that the robot did provide for a more immersive activity where the urge to do something else was diminished. Due to the fact that the robot gives more active guidance than paper instructions, it could be hypothesized that the participants were more actively feeling part of the activity.

88 -For this research question the results also proved not to be conclusive. The only result that could be viewed as remotely significant is the result for question 7 (P=0.073). This could be caused either by the positive encouragement given by the robot, and/or the added functionality of searching for pictures to draw.

This could be because of the confounding factor related to the painting activity itself; participants who liked to paint preferred the activity either way with or without the robot.

116 -The results do not show a conclusive effect in general towards the added value of having a robot performing the activity. This is can be attributed to different possible causes.
156 +We followed a within-study approach with a control group and a test group. The control group was first instructed to perform the painting activity without Pepper and then move on to the same activity but this time with Pepper. The test group was told to do vice-versa to minimise any transfer effect.
117 117  
118 -First of all, the questions that were asked were more focused on the experience of the activity rather than the specific added value a robot might give when doing such an activity. It is understandable that painting can be generally viewed as an enjoyable and engaging activity, so when focusing on the enjoyment, it could be understood that the robot does not make a significant impact there. However, the robot might give significant improvement in terms of support, motivation and structure during the activity. Especially if the test was conducted on actual PwDs. For future work it would be interesting to explore during the design process on which parts of the activity the robot might be able to do more than paper instructions and to investigate how these contributions might be measured.
158 +We used questions Q2, Q3, Q5, Q13, Q14 to answer our research question 1 and questions Q1, Q4, Q6, Q7, Q8, Q9, Q10, Q11, Q12 to answer our research question 2. Based on the results we saw in the above sections, unfortunately, the results we obtained to answer our research questions related to Engagement and Agitation are not significant. These questions were picked from the [[PACES questionnaire>>doc:Main.b\. Human Factors.Measuring Instruments.EV01\: Phsyical Activity Enjoyment Scale.WebHome]]. The aggregated score of the results based on the PACES questionnaire was 0.228 which is not significant enough for our threshold of 0.05. Although one interesting thing to note is that the raw scores for the questions were always higher for questions that were positively associated with the Pepper robot. Although this could also have been because the participants were our colleagues and they could have been biased in their responses.
119 119  
120 -Moreover, as we alluded to earlier, the activity might be experienced highly different for PwDs than 20 year old TU Delft students. Therefore, it is hard to draw any conclusions on the use of the robot by testing it on people who do not need much support from it.
160 +The participants were also required to answer two more questions AQ1 and AQ2 after the activity which was used to investigate whether the participants preferred the activity with a robot or without it. The mean responses for AQ1 were in favour of painting with the robot but for AQ2 no definite conclusion could be made. This could be because of the confounding factor related to the painting activity itself; participants who liked to paint preferred the activity either way with or without the robot.
121 121  
162 +Overall our results are inconclusive in terms of statistical significance although the raw scores are in favour of the robot even with the limited participant size test that was conducted. Unfortunately based on the experiment we did, the limitations of the experiment such as not having actual PwDs we are unable to conclusively evaluate the added value of a robot.

123 123  
124 124  Our project sought to offer support to individuals suffering from dementia in their passion for painting, with the objective of enhancing their emotional well-being. While human caregivers could provide such assistance, utilizing a humanoid robot such as Pepper for painting activities provides several advantages. Pepper has the potential to enhance and sustain the interest of individuals with dementia in painting by encouraging them to paint and providing assistance during the activity. As a result, the quality of life of these individuals could be improved, which may be augmented by playing calming music during the painting process. In addition, this activity could bring together the individuals with their family members, as personalized painting recommendations could be provided, and photos of completed paintings could be shared. Rather than completing the painting activity for the individuals, Pepper would guide them through the process, promoting a greater sense of independence and self-sufficiency.
