1 -**Design problem: **The PwD likes to paint and was quite enthusiastic about painting in their past life but because of dementia they are not as active and can sometimes forget about what made them happy, who they are and their overall identity. We would like to help them to maintain their identity by engaging in the painting activity which brought them joy. But this can be further enhanced by providing them with a personalised picture to draw which has some meaning to them, which they hold dear.
1 +**Design problem: **The PwD would like to paint but is not as active as it used to be because of the dementia condition. The Pepper robot in this case helps them to perform the activity and provides meaningful guidance and suggestions while they are doing the activity.

3 -**Design solution:** In this design pattern, the robot allows the PwD to paint something personalised to them, which will be an old memory with the help of a picture of that event, or something random that they wish to draw.
3 +**Design solution:** In this design pattern, the robot first instantiates the interaction by first asking the PwD whether they want to perform the painting activity and then at certain milestones of the painting. The suggestions would not be annoying or too frequent so as to not cause annoyance but at proper intervals. The robot's tone remains friendly and uses open gestures to make the interaction less formal.

7 -**Design rationale: **This design pattern follows the design patterns mentioned in [1], where they show how personalisation can help and improve the overall project's design.
7 +**Design rationale: **This design pattern follows the Didactic Communication pattern introduced by Khan et al., where there is a transmission of information from the robot to the human agent. By explaining the activity, participants will know what to expect and how they can participate in the activity.

9 +**Example: **For our use case, Pepper triggers the activity using speech and hand gestures, which is to help the PwD paint. The speech rate is slightly lower than average considering the age and cognitive abilities of the participants. Pepper then explains the steps involved such as the style of the painting and the topic. Appropriate suggestions and instructions are given at proper intervals. Pepper confirms that the explanation is understood and if not, repeats the explanation. For detail on the parameter setting, see the Table below.
