21 -The test will be with students from the university of Delft that are also following this course. For the results to be valid 15 participants in the research is the minimum amount. Since the decision was made for in-between subject design, which will be elaborated more in the Experimental Design section, there are thus 30 participants necessary. Due to the time constraint and the amount of students in the course, 30 participants will probably not be reachable for this experiment so less students will participate. Also the use of a control group is not within reach because of the lack of resources.
21 +The test will be with students from the university of Delft that are also following this course. For the results to be valid 15 participants in a research is the minimum amount as presented by research of Marc Brysbaert (2019) [1]. Since the decision was made for in-between subject design, which will be elaborated more in the Experimental Design section, there are thus 30 participants necessary. Due to the time constraint and the amount of students in the course, 30 participants will probably not be reachable for this experiment so less students will participate.

23 23  The participants are all young and do not have any form of dementia. The results of the research can thus not be seen as sufficient for a real-life implementation of the prototype. The students will be familiar with the robot and thus further explanation of the working of the robot is less relevant. Also, the students will feel more comfortable with the robot from the start. This might be very different to the PwD that might be a little hesitant in interacting with the robot. The integration of that aspect will be of great importance before real implementation.

29 -Pepper will be turned on and will start a conversation with the participant. It will ask the participant to go on a walk and based on the answer Pepper will go on the walk immediately or will try to motivate the PwD to go on a walk with him. During the walk Pepper will ask the participant questions to keep the participant engaged and keep continuing on the walk. So for the experiment a Pepper robot, the Choregraphe software and also freedom of movement is needed.

33 -The interaction will take place in a TU Delft facility. The experiment will be hold in the Insyght lab. Unfortunately, the space of the room is small compared to a an actual garden. The robot needs some space to move, hence we will make sure to move everything moved out of the way and that other students (who are not experiment at the moment) wait in the room next.

Also the walk will not be as long as it would be in the actual garden.
34 34  
35 35  The room also has a different surface than an actual park. However, our experiment focused more on the motivation to go outside then the walk itself. The difference in surrounding, a room instead of a garden, might have a little effect on the experience of the participant. However, the motivation will probably not be affected by the surroundings as much.

43 +The participant is expected to perform the experiment according to the following plan:
43 43  
45 +* Step 1: The participant needs to stand close enough to the robot to have an interaction/conversation with Pepper
46 +* Step 2: The participant needs to look the robot in the eye
47 +* Step 3: The participant needs to actively answer the questions provided by Pepper during the experiment
48 +* Step 4: When the participant has been motivated for a walk he/she needs to walk for 1 to 2 meters with the robot
49 +* Step 5: During the walk the participant is expected to contribute in some small talk with Pepper
50 +* Step 6: When the walk is finished the participant needs to communicate with Pepper after which Pepper will say goodbye and the actual experiment is over
51 +* Step 7: After the experiment the participant needs to fill in the questionnaire provided by group 4

45 -The student is expected to communicate with the robot by doing the following:
46 -
47 -~1. The student looks the robot in the eye.
48 -
49 -2. The student communicates with the robot through a small conversation in the beginning.
50 -
51 -3. When the student agrees to go on a walk, he/she is expected to walk 1 or 2 meters with it (small distance due to the room size).
52 -
53 -4. The student will make a small talk with the robot as well.
54 -
55 -5. When the walk finishes (after the walk), the student communicates with the robot again.
56 -
57 -6. Finally, the student fills in the questionnaire provided by us

60 60  == 2.4 Measures ==
61 61  
62 62  If our situation, we would like to measure whether the provided motivation indeed has effect on the person. We would like to compare which one has more effect as well. That could be measured by seeing whether they indeed go on the walk or not. We would also like to measure how long it takes to convince them to go on a walk when they do not want. We would also like to measure their emotions during and after the walk. Did they enjoy it? Were they bored? Did they feel lonely? That could be measured with the feedback asked after the walk.
