a. Prototype

This section shows the interaction designs for our prototype. The interactions we designed consist of two stages: the 'motivation stage' and the 'walking stage'. The motivation stage is immediately followed by the walking stage. These interactions are designed for our persona Bob.

The following two figures show the interactions with motivation-oriented motivation.

The following two figures show the interactions with goal-oriented motivation.

In both scenarios, the robot makes a maximum of three persuasion attempts, before giving up. We attempted at making the persuasion attempts personal to Bob. The sentence "Going for a walk will make you happy!", relates to Bob's anger issues, aiming for him to realize that it might increase his mood. Furthermore, the persuasion "Walking is a great way to blow off some steam." relates to his persona that likes going to the park because it helps him blow off steam. These persuasions are in place to help him remember and realize the positive effects of going for a walk.

These interactions were programmed using Choregaphe [1]. A noticeable observation was that when a person stands too close to the robot, it does not move due to built in safety systems. So to ensure a well-working interaction, the participant needs to stand at least about 1.5m from the robot.
