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.
	1	+**Design problem: **The specific role of the [[Humanoid Robot>>doc:Main.c\. Technology.Humanoid Robot.WebHome]] (e.g., Pepper)  in the group activity (e.g., a game) and the game or activity to play, are not yet known to the [[Person with Dementia>>doc:Main.sdf.Stakeholders.Person with Dementia.WebHome]] (i.e., the participants). The participants do not know how the activity has to be played and how they should participate.

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:** In this design pattern, the robot follows a monologue to explain the activity and what the participants are expected to do in the session. After this monologue, the robot asks for confirmation about whether or not the explanation has been understood. If this is not the case, the explanation is repeated. The tone of the robot remains friendly and uses open gestures to make the interaction less formal.

	5	+**Use when: **After the introduction but before the start of an activity, when participants are unfamiliar with the goal of the interaction.

7	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.
	9	+**Example: **In our use case (i.e. "group exercise"  as specified by group 4 of the SCE-course in 2020), Pepper explains using speech and hand gestures, the goal of the activity, which is to perform exercise moves together with the PwD. 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 playing the song and demonstrating the dance moves that the participants are expected to repeat. Pepper confirms that the explanation is understood and if not, repeats the explanation. For detail on the parameter setting, see the Table below.
