10	10	**Overview**
11	11	The design pattern above demonstrates the interactions between Nao and the PwD. The top pattern concerns UC01, the mealtime discourse. The bottom pattern concerns UC02, the mealtime reminder. In this section, the design pattern will be explained step by step.

34	34	This way, after a couple interaction sessions, the PwD might link the food preparation music to the idea to go and eat something.

75	75	//The supervisor//
76	76	This design addition suggestion does not consist of clearly defined steps, but is just intended to demonstrate that the caregiver, as supervisor, could have the opportunity to impact the mealtime reminder interaction between the robot and the PwD. However, in the interaction design patterns, the interaction between the supervisor, the PwD and the robot will be further explained.

	77	+== Interaction design patterns ==
	78	+In the section below, we will elaborate on the basis of the interactions between the robot and the end-user of the system, the PwD.
	79	+
	80	+**Robot gets PwD’s attention**
	81	+//Why//: to start both UC01 and consequently UC02, the robot has to get the PwD’s attention, without startling the PwD.
	82	+
	83	+To get the PwD’s attention by the robot, the following types of interaction are used:
	84	+• The Robot plays start playing music that suggests that a Use Case is about to commence.
	85	+• The Robot greets the PwD.
	86	+• The Robot asks the PwD introductory questions to gently start the conversation between the Robot and the PwD like: “How are you doing?”, “How are you feeling?”
	87	+
	88	+The same interaction types can be used in case the Robot aims to finish the interaction with the PwD.
	89	+
	90	+**Robot stimulates the PwD to self-reflect**
	91	+//Why//: it has been shown that, by stimulating a PwD to reflect on their day, the PwD’s brain is triggered to stay active. This gives the sense for the PwD to be less alone. Furthermore, reflecting on one’s day has proven to be an effective form of memory training. If the self-reflection is effective, in our Use Cases, the PwD might even come to the idea to eat or have a drink him-/herself.
	92	+In the end, the information gathered in the self-reflection interactions can be used to determine what’s healthiest for the PwD in terms of feeding him/herself.
	93	+
	94	+To stimulate the PwD to self-reflect, the following can be done by the Robot:
	95	+• The Robot asks the PwD questions about his/her day like: “What have you been doing today?”
	96	+• The Robot asks the PwD questions, linking specifically to a certain activity, like: “Did you have breakfast?”
	97	+• The Robot asks the PwD questions that link to the previously asked question, like: “What did you have for breakfast?”
	98	+• The Robot asks the PwD questions to stimulate the PwD to do something, like: “Isn’t it time for you prepare lunch?”
	99	+• The Robot plays music to make the PwD reminisce
	100	+
	101	+//Context//
	102	+The self-reflection interaction can be used in the following situations:
	103	+• The mealtime discourse: the Robot can check if the PwD has eaten something
	104	+• The water check: the Robot can check if the PwD his having a drink
	105	+• The company check: the Robot can check if the PwD is having company
	106	+
	107	+**Robot calms the PwD**
	108	+//Why//: as described in previous sections, many people with dementia might experience negative emotions such as anger and agitation during mealtimes. Therefore, interactions between the Robot and the PwD to calm the PwD are developed.
	109	+
	110	+For the robot to calm the PwD, the Robot can do the following:
	111	+• The Robot plays music to the PwD: it has been shown that music can affect a person’s mood.
	112	+• The Robot can verbally calm the PwD by saying calming words like: “It’s okay, I am here for you.”
	113	+
	114	+//Context//
	115	+The calming of the PwD can be applied in the following contexts:
	116	+• While the PwD is eating the food he/she prepared
	117	+• While the PwD is having a drink
	118	+• While the PwD is made aware of the fact that the Robot is keeping the PwD company
	119	+
	120	+**PwD answers the Robot**
	121	+//Why//: To determine the next step in the conversations between the PwD and the Robot, the PwD has to answer the Robot’s questions.
	122	+
	123	+The PwD can answer the Robot’s questions and suggestions in the following ways:
	124	+• The PwD answers the Robot’s questions verbally
	125	+• The PwD taps the Robot. This can for instance be done after the PwD has finished a certain task or if the PwD would like the music to stop.
	126	+• The PwD can do nothing. In this case the interaction will stop after a given amount of time.
