1 -Evaluation is an iterative process where the initial iterations focus on examining if the proposed idea is working as intended. Therefore, we want 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 conduct a small pilot study with students, who role-play having dementia. We then observe their interaction with Pepper to examine the effectiveness of our dialog flow in preventing people from wandering.

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.

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:
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.

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.
52 +After this preparation, the participant is told to (try to) leave the building. The participant and robot have an interaction where the robot is trying to convince the participant to stay inside.

55 +== Measures ==

57 +We will be measuring this physically and emotionally.
58 +Physically: whether the participant was stopped from leaving the building or not.
59 +Emotionally: evaluate their responses to the robot and observe their mood before and after the interaction.
