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: **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.
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.
