1		-Evaluation is an iterative process where the initial iterations focus on examining if the proposed idea is working as intended. Therefore, we wanted to first understand how realistic and convincing the provided dialogues and suggested activities are, and would they be able to prevent people from wandering. To examine this, we conducted a small pilot study with students, who role-played having dementia. We then observed their interaction with Pepper to examine the effectiveness of our dialog flow in preventing people from wandering.

	26	+A between-subject study with students who play the role of having dementia. Data will be collected with a questionnaire that participants fill out before and after interacting with Pepper. The questionnaire captures different aspects of the conversation along with their mood before and after the interaction with Pepper.

	28	+For our between-subject study, our independent variable is Pepper trying to distract the users by mentioning different activities along with the corresponding music. Through this, we want to measure the effectiveness of music and activities in preventing people from leaving the care home, which is thereby our dependent variable. So we developed 2 different prototype designs-
	29	+
	30	+Design X - It is the full interaction flow where Pepper suggests activities and uses music to distract people from leaving.
	31	+Design Y - It is the control condition where pepper simply tries to stop people from leaving by physically keeping its hand on the door.

37	37
38		-1. Observe the participant's mood and see how the conversation goes. Observe the level of aggression (tone, volume, pace)
39		-1. Observe whether the mood is improved and the decision has been changed.
40		-1. Observe how natural the conversation is. (conversation makes sense)
41		-1. Participants fill out questionnaires.
	42	+We will explain to the participants the goal of this experiment and what do they need to do to prevent ambiguity. Therefore, as our participants are students and only playing the role of having dementia, we will give them a level of stubbornness/ willpower with which they are trying to leave the care home.
	43	+Participants will also be given a reason to leave, from the below list:
42	42
	45	+going to the supermarket
	46	+going to the office
	47	+going for a walk
	48	+
	49	+After this preparation, the participant fills a part of the questionnaire.
	50	+
	51	+Experiment:
	52	+The participant begins interacting with Pepper who is standing near the exit door. The participant and robot have an interaction where the robot is trying to convince him/her to stay inside.
	53	+
	54	+After Experiment:
	55	+After the participant finishes interacting with Pepper, he/she will be asked to fill out the remaining questionnaire. Almost all the questions in the questionnaire collect quantitative data, using a 5 point Likert scale. The questionnaire also used images from Self Assessment Manikin (SAM) so that user can self attest to their mood before and after their interaction with Pepper.
