1 -Our robot aims to help delay the stage of dementia or slow down the deterioration of memory. The best situation is that we can test the robot with real PwD and in a relatively long time period to see if this robot really works, which is impossible for our project. So our evaluation performs in a group control way. Participants are divided into two groups, group A with the intelligent one, and group B with the dummy one.

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.

34 +First, all participants would sign a consent form that informed them of the usage of the collected data and our goal of evaluations.

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 dumb 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.

48 +==== Questionnaire ====

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)
