3 Our research topic is:
4 The effect of goal-based and emotion-based explanations in prompting PwD for physical activity.
5 \\We will create two systems, both trying to motivate the PwD to go for a walk in the garden. One will use goal-based explanations and the other emotion-based explanations.  Maybe we would also need a control group (no explanation), resulting in three systems.

14 The between-subject study design fits with the limited time that we have. It also makes sure there's no learning effect like what could occur with a within-subject study. We do have to take into account the potential differences between the groups meaning we cannot take the results as a direct conclusion.

16 After each evaluation session, the participant will be asked to fill in a questionnaire. There's quite some existing for human-robot interaction. However, they are more about the usability of the system. While we see our system just as a conversational motivator for going outside. So we don't see these questionnaires as fit:

21 All participants of the evaluation will be part of the course. So they will all be familiar with the robot in question. They will all be students at the TU Delft aged 20-25.
