25		-Roughly sixteen participants are expected for our evaluation. To validate our research question that the quiz will help people better memorize music-activity links, participants will be divided into two groups, Group A and Group B. Both groups will be asked to memorize certain pairs of music and corresponding activity as prior knowledge. Group A, which is the control group, will not have NAO to assist with learning music-activity links through quizzes while Group B will have him as the experimental group. Details on the tasks assigned to each group will be further described below.
	25	+We invited 19 participants. To validate our research question that the quiz will help people better memorize music-activity links, participants will be divided into two groups, Group A with the intelligent robot(9 participants) and Group B(10 participants) with the dummy robot.

29		-The experiment will be conducted to simulate the reinforcement learning process of musical memory related to daily activities and to investigate if the quiz is indeed able to help with the learning. The group of participants will be divided into 3 subgroups that simulate patients in different stages of dementia. The participants will be given artificial memory loss by forcing them to remember a large number of songs they have to associate with certain activities. From each group one of the participants will be asked to play the caregiver and another participant will take the roll of loved one. With these participants the interactions between the actors will be tested. The interactions are described in the design patterns.

31		-When the participant playing the role of patient has learned the association between the music pieces and activities the robot will start playing certain pieces of music. The participant has to recall the correct activity associated with the music piece. When this is wrong the loved one can step in and call to remind the

	34	+First, all participants would sign a consent form that informed them of the usage of the collected data and our goal of evaluations.
	35	+
	36	+==== Step 1 ====
	37	+
	38	+In our prototype, users can personalize the link between music and activities based on their existing intrinsic knowledge. But due to the limited time and requiring a comparable result between groups, in evaluation, we forced 6 pieces of music and activities. Participants listened to the music and were asked the remember the associated activities.

	40	+==== Step 2 ====
	41	+
	42	+Participants in two groups would play with the robot for 3 minutes. Participants in group A would play with the intelligent robot and group B would play with the dummy robot.
	43	+
	44	+==== Step 3 ====
	45	+
	46	+In the end, the participants would take a quiz to see how much they remembered. They are also asked to fill in a questionnaire including the feeling of the robot and possible feedback.
	47	+
	48	+==== Questionnaire ====
	49	+
	50	+1. How many questions did you answer correctly? (Points from 0-6)
	51	+1. You feel the robot can help you remember the task. (Agree, Neutral, Disagree)
	52	+1. You feel the robot is annoying. (Agree, Neutral, Disagree)
	53	+1. Based on the given system usability scale, please give our robot a score.(0-100)
	54	+
	55	+Except for the previous questions, we also collect feedback from participants
	56	+
	57	+1. What did you like most about the robot?
	58	+1. What did you dislike most about the robot?
	59	+1. Do you have any further suggestions? (*optional)
