1 = Problem statement and research questions =
2
3 The main use cases that the evaluation focuses on are UC001: Daily todo list and UC005: Quiz. Based on the claims corresponding to those use cases, we derive the following research questions:
4
5 1. System A: the robot does not do anything
6 System B: the robot plays music associated with tasks
7 Research question: Are participants more likely to remember their daily tasks when using system B, compared to system A?
8 1. System A: the robot plays a song and regardless if the answer is right or not, it switches to a different song.
9 System B: the robot plays the same song until the user gets it right
10 Research question: Are participants happier to interact with the robot and more effective at linking tasks to music when using System B, compared to system A?
11
12 = Method =
13
14 We are doing a mixed-method approach. We are producing quantitative data from questionnaires after the interaction with the robot, by asking them how they felt about the whole experience. By measuring this data, we will assess if we successfully achieved our claims and determine the answers to the research questions.

16 == Participants ==
17
18 Roughly 18 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.
19
20 == Experimental design ==
21
22 The experiment will be conducted by simulating the interaction between the patient, robot and other actors. 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.
23
24 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
