34.1 | 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: |

36.1 | 4 | |
| |
40.1 | 5 | 1. System A: the robot does not do anything |
| |
34.1 | 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? | ||
| |
45.1 | 8 | 1. System A: the robot plays a song and regardless if the answer is right or not, it switches to a different song. |
| |
34.1 | 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? | ||

49.1 | 14 | Our group decided to use a mixed-method approach for the evaluation. Quantitative data will be derived during the experiment such as the number of mistakes the participant makes during the quiz. Moreover, qualitative data expected to be gathered through questionnaires, such as to what extent participants are satisfied with using the robot, is also adopted for evaluation. By measuring these two types of data, we will manage to assess if our claims are achieved and the research questions are answered. |

48.1 | 18 | 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. |

1.1 | 21 | |
| |
49.1 | 22 | 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. |

8.1 | 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 |
