  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.

++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.
++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-
++
++Design X - It is the full interaction flow where Pepper suggests activities and uses music to distract people from leaving.
++Design Y - It is the control condition where pepper simply tries to stop people from leaving by physically keeping its hand on the door.

  == Participants ==
--17 students who play the role of having dementia. They will be divided into two groups. One group (11 participants) will be interacting with the intelligent (group 1) robot while the other group (6 students) will interact with the unintelligent robot (group 2).
--It is assumed that all participants are living at the same care center.
--Before they start, they can choose how stubborn they want to be and where they want to go.
++The ideal participants for our user study would have been people suffering from dementia. As the people in this section fall under vulnerable groups, testing with them would have been very difficult due to the current pandemic situation. Therefore we planned to conduct our experiments with students instead.
++Our experiment involves 17 students who play the role of having dementia. They will be divided into two groups. One group (11 participants) will be interacting with design X while the other group (6 students) will interact with design Y.
  == Experimental design ==
--All questions collect quantitative data, using a 5 point Likert scale wherever applicable.
++**Before Experiment:**
++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.
++Participants will also be given a reason to leave, from the below list:
--1. Observe the participant's mood and see how the conversation goes. Observe the level of aggression (tone, volume, pace)
--1. Observe whether the mood is improved and the decision has been changed.
--1. Observe how natural the conversation is. (conversation makes sense)
--1. Participants fill out questionnaires.
++* going to the supermarket
++* going to the office
++* going for a walk
--== Tasks ==
++After this preparation, the participant fills a part of the questionnaire.
--Because our participants only play the role of having dementia, we will give them a level of stubbornness/ willpower with they are trying to leave. We try to detect this level with the robot.
--Participants from group 1 (using intelligent robot) will also be given one of the reasons to leave, listed below:
++**Experiment:**
++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.
--1. going to the supermarket
--1. going to the office
--1. going for a walk
++**After Experiment:**
++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.
--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.
--
--
--== Measures ==
--
--We will be measuring this physically and emotionally.
--Physically: whether the participant was stopped from leaving the building or not.
--Emotionally: evaluate their responses to the robot and observe their mood before and after the interaction.
