For our evaluation, we decided to implement a vertical prototype that shows one slice of the full functionality. Because not all functions could be implemented in detail, we need to hardcode some parts.
We also need a control condition to test if the provided dialogues and music are the reason why a person stays. Hence we have designed 2 different prototypes (referred to as Design X (Full Interaction) and Design Y (Control Condition) in Test). Both prototypes are described in detail below.
Full interaction flow - Design X:
The robot explains the procedure of the activities to PwD and starts small talks to check the patients' states. Still, as it is only a pilot prototype it has limited ways to react to users' speech, the robot only knows how to play the Music Bingo Game right now.
In the current prototype, the suggested activities and music are not personalized and have been used according to the team's liking. In the later iterations, they should be changed according to the user's individual preferences.
Control Condition - Design Y:
This prototype does not give any extra interactions with the patients besides the game explanation.
We are using this as a control condition to compare how the more human-like interactions would take effect on the patients.
