3 -For our research, we are looking into the effect of either using goal-based motivation or emotion-based motivation in promoting PwD for physical activity. Two systems will thus be designed; one motivating using emotion-based explanations and the other using goal-based motivation. The product will motivate the PwD to go for a walk in the park stimulating the amount of physical activity. It has been shown that physical activity, an increase in emotional stability and more goal-based activities can increase the mental and physical health of the PwD. Since 70% of the PwD have a lack of motivation, apathy and lack of interest in activities this project could have a great influence on the lives of these people.

17 -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.

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 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.

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

32 32  
33 -The interaction will take place in a TU Delft facility. The experiment will be held in the Insyght lab. Unfortunately, the space of the room is small compared to 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 experimenting at the moment) wait in the room next. Also, the walk will not be as long as it would be in the 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 than 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.

38 38  
39 -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.

55 -If our situation, we would like to measure whether the provided motivation indeed affects 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.

57 -In an optimal scenario where we can test the robot on PwD. We would have measured the number of times a person went out. We would also have measured the effect of the goal and emotion-based motivation on the long-term over the people. Whether it will be less effective over time or not. We would also measure the emotional effect on the caregivers and the functional effect. By the functional effect, we mean whether they indeed have more time to do other tasks or not. It would also have been perfect if we could measure the effect of the walks on the PwD and their health.
