15 15  Sadly enough we are not able to perform the experiment on PwD in a real time situation and over a longer time. The experiment will take place on one single day and thus the long-term effect of either goal-based or emotion-based motivation cannot be seen. However the difference in motivation can still five different results in a single experiment and these results can already show some promising results for further research.

19 -The test will be with students from the university of Delft that are also following this course. 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 is contradicting with 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.
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.

23 -The Pepper robot will be turned on and in a "normal" situation would walk around to monitor the state and activity of the PwD in the care facility. However, because of the lack of time and since we are now only working with students Pepper will search for a face and will then start interacting with the student. The interaction will take place in a TUDelft facility. The experiment will be hold in a room with the robot. Unfortunately, the space of the room is small compared to a an actual park. 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. 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. Due to the fact that we want to compare emotion-based and goal-based motivations, ,multiple experiments will be taken. One in which we only test emotion-based motivation and another in which we only test goal-based motivation. Both are measured by a questionnaire, whether there the students indeed agree to go on a walk and how long it takes until the robot convinces a student to go on walk. We plan to do the experiment on a fellow team, which can exist of 4 or 5 people. We want to divide them, half will do the experiment regarding emotion-based and the other half the goal-based one.
27 +**Methodological set-up:**
24 24  
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.

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.

37 +**Subject design:**
38 +
39 +For the experiment it was chosen to do in-between subject design as the learning affect in the within-subject design might negatively impact the results. When the same participants have to perform the same routine twice, they might get bored and frustrated due to some repetitions in questioning in the different motivation methods. In the in-between subject design multiple experiments will be taken with different participants. The total group of participants will thus be divided in half regarding either the emotion-based or the goal-based motivation. Both are measured by a questionnaire, which will be discussed in more detail later on in the evaluation part.

67 -The procedure will be as followed: the robot will see a fellow student. Ask him/her to go on a walk given a reason to motivate him/her. If the student accepts, then they on a walk. If the student says no, then the robot will provide more motivational reasons to go on a walk. Of course, the robot should not be annoying and insist too much. Hence, after providing two or more reasons if the student still says no, then they do not go on a walk. If the student changes his/her mind and accepts to go on a walk, then we are in the next phase of the test. During the walk, the robot will have a small social talk with the student. If the student decides to go back earlier, then the robot will try to convince him/her to keep going. After the walk, the robot will ask how to the walk went and that he have enjoyed it. The student will also answer some questions regarding the whole experience.

86 +The claims that need to be tested are thus:
87 +
88 +- The effect of emotion-based motivation; The PwD is able to comprehend the emotion that is being conveyed and in that way is motivated to contribute in the activity of walking in the garden.
89 +
90 +- The effect of goal-based motivation; The PwD is able to comprehend the goal and end-state of the promoted activity and in that way is motivated to contribute in the activity of walking in the garden
91 +
92 +- Whether there is a noticeable difference between emotion-based and goal-based; The PwD is able to communicate how he/she feels and score the walk.
93 +
94 +
95 +The robot and students need to perform the following tasks:
96 +
97 +~1. Pepper will be turned on and will scan/check his environment
98 +
99 +2. Pepper will look for a face and will turn to the person that he sees
100 +
101 +3. Pepper will recognize a face and will introduce itself to the student
102 +
103 +4. Pepper will then ask to go for a walk after which the student can either say yes or no
104 +
105 +5. Pepper will start motivating based on the answer that the student gives:
106 +
107 + 5.1 When the student says yes, Pepper will start walking with the student and during the walk will have some small talk
108 +5.2 When the student says no, Pepper will start the motivational part of the experiment. For the first experiment Pepper will use emotion-based motivation and for the second experiment Pepper will use the goal-based motivation
109 +5.3 If the student then decides to say yes, then Pepper will start walking with the student and during the walk will have some small talk
110 +6. After the walk/activity is finished Pepper will thank the student and will state again how important it is to stay active
111 +
112 +7. Then the student is asked to answer some questions to evaluate the experience.
