Requirements
The two main use cases we chose to focus on were the UC01: Meal Time Discourse and the UC02: Eating reminder, and the requirements below are chosen for the robot to be able to perform them.
| ID | Function |
| RQ01 | The robot can play music that suits the situation and the emotional state of the PwD |
| RQ02 | The robot can greet the PwD in a personal and varied manner |
| RQ03 | The robot can understand the semantic meaning of what the PwD is saying, such as agreement and disagreement |
| RQ04 | The robot has a scheduling system, to know when to remind about eating and drinking |
1. Key features
1.1. Feature: Wellbeing discourse
1.1.1 Introduction
On a preset time each day, the robot engages in a discourse with the patient focusing on their physical and mental wellbeing. The discourse spans many aspects of the patients state, incl. physical wellbeing (hunger, thirst, activity, tiredness), as well as mental wellbeing (cognitive ability, memory).
1.1.2 Patients response
To avoid negative response from the patient, the discourse on mental wellbeing should be tailored to not distress the patient, even though it could cause them to realise the gravity of their symptoms. The discourse could focus more on reminiscence, which has received good responses from the patients [SOURCE].
2. Minor features
2.1. Feature: Mealtime reminder
- Subfeatures: Mealtime and drinking reminders
2.2 Feature: Mealtime discourse
After or during the mealtime the robot engages in a discourse about the meal and how it made the PwD feel.
2.3 Feature: Engaging in the discourse
To avoid startling the patient, all the features which include the robot starting the discourse, the robot plays a soft "wake-up" tune, before beginning the discourse.
2.4 Feature: Snooze button
Tapping the robot on the head snoozes all alerts until the next programmed alert or at least 2h.
