2 2  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 4  1. System A: the robot does not do anything
5 5  System B: the robot plays music associated with tasks
6 6  Research question: Are participants more likely to remember their daily tasks when using system B, compared to system A?

By measuring this data, we will assess if we successfully achieved our claims and determine the answers to the research questions.
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.

22 -Due to covid restrictions, we have to “simulate” our robot-human interaction with elderly people affected by dementia. For that reason, we will ask roughly eighteen people how will pretend to be people with different dementia types, the loved ones or the caregiver. We will create three groups / six people in each. In each group, one person will “play” the role of a caregiver, one plays the loved one, and the remaining four people will do the role of the person with dementia. In each group, the “onset of dementia played” should be different. In Group A, people act like they just have early-onset symptoms, but they are almost fully functioning. They sometimes get confused, but these moments swiftly pass and they are back to their true selves. In Group B, people should have a harder time keeping track of things, forgetting about tasks, people and memories should be common. These people’s life is constantly affected by the disease, but they sometimes have clear moments when they are back to their original selves before dementia. In Group C people have late-onset of dementia. Constant confusion is more common than moments of clarity which usually doesn't last long. People should have a hard time keeping track of anything, and remembering is not something that’s even possible anymore.
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.

26 -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.
