This was done to bring some joy and comfort into their lives, especially if they previously enjoyed doing it. This could be done with a human caretaker but having a humanoid robot like Pepper has certain advantages in the overall painting activity.

However, the robot might give a 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 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.

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.

126 -We did a study to evaluate the effectiveness of having a robot like Pepper assisting the PwD with painting instead of the PwD doing the activity alone. Our results based on the responses obtained from our custom PACES questionnaire were statistically insignificant and hence we could not conclusively answer our research questions related to engagement and agitation. However, the raw scores of the questions were always in favor of having the robot while performing the activity which could indicate a positive attitude towards having the robot. Due to certain practical limitations of the course, we could not conduct the experiment with actual PwD or set it up in such a way but given enough time and effort the current implementation in Pepper could be extended to an actual care home with PwDs.
