19 -Sadly enough we are not able to 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.

23 -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 researcher Marc Brysbaert [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 number of students in the course, 30 participants will probably not be reachable for this experiment so fewer students will participate. Also, the use of a control group is not within reach because of the lack of resources.

25 25  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 which might be a little hesitant in interacting with the robot. The integration of that aspect will be of great importance before real implementation.

31 -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 are needed. The full step-by-step schedule of the experiment is given in the attachments for both the [[goal-based motivation>>attach:Ontology & robot design - goal-based.pdf]] and the [[emotion-based motivation>>attach:Ontology & robot design - emotion-based.pdf]].

41 -For the experiment it was chosen to do in-between subject design as the learning effect 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.
