	1	+**Design problem: **The PwD would like to paint but is not as active and confident about their painting capabilities as they used to be because of the dementia condition. The Pepper robot in this case provides meaningful motivation and encouragement while they are doing the activity.

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.
	3	+**Design solution:** Pepper does this by saying words of encouragement and motivating the PwD to preserver and not give up on the task. Of course, if the PwD wants to take a break, is done for the day or is satisfied with the painting they have done then Pepper won't keep on egging them to continue but would understand this stage and congratulate the PwD for an awesome painting which they can be proud of and show their family members.

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.
	7	+**Design rationale: **This design pattern follows the strategies mentioned in [1] to provide motivation and encouragement to the PwD.

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.
	9	+**Example: **For our use case, Pepper provides such encouragement and motivation at appropriate intervals making sure that the frequency isn't too much or less. Since Pepper does this verbally the speech rate is slightly lower than average considering the age and cognitive abilities of the participants. For detail on the parameter setting, see the relevant. For detail on the parameter setting, see Table below.
