Functions

Requirements

The requirements together aim to enable the robot to successfully complete all tasks set out in the use cases from the original design.
We identified two main use cases the robot should be able to perform, which we will work out in more detail. These 2 use cases are the Daily todo list: UC001 and the Quiz: UC005 which have some dependencies which are also added.  
The requirements are as follows:

Main Use cases

RQ001: Robot has the ability to play sounds
Function description: It is critical for the functionality of the system that the robot is able to play specific songs at certain times. In order to achieve this the robot should be able to play sounds at an audible volume in the room and the Choregraphe Studio program should allow for picking and streaming songs to the NAO. This can be seen as one of the most important requirements as without it the system can not execute it's core functions.

RQ002: Robot should recognize an indication of being done
Function description: In order to know when the patient has completed a task, or the patient wants to stop the music as he knows the task to perform, the robot should be able to recognize an indication of being done. This indication can be given in various ways, one of those is through speech which depends on RQ009. However, other indications can be used to denote being finished such as detecting a hand signal from the patient or visually recognizing the completion of the current activity.

RQ004: Have some way of modifying the TODO list and the music associated with the tasks
Function description: Not directedly related to the main use cases, the requirement for being able to modify the music and schedule is still vital for the functionality of the system. If the data is not able to be created or modified then no personalized music can be played at certain times during the day. Thus making the system useless and making it a vital requirement for enabling the core functions of the system. The creation of the patients schedule and the association of certain personalized music can by done by the caregiver or loved ones and easily edited through a web portal. 

RQ009: Robot should recognize spoken words

RQ007: Robot has games and rules stored in memory and is able to recognize the players
Function description:

RQ008: Robot can monitor an ongoing game
Function description:

RQ010: Robot should recognize when the patient suddenly stops interacting
