Requirements

In order for the system to properly improve the safety of the people with dementia residing in the care home, it needs to be able to perform several different functions. Together, these functions will allow the system to engage in conversation with the person with dementia and try to convince them to stay inside, as well as take all the necessary actions in the event that the person with dementia is not convinced by their conversation with the system. The functions listed below are classified in several different categories, ranging from most important to least important. Currently, not all of these requirements are fully satisfied, and the system is in a more basic version than the one envisioned. The requirements not currently implemented are listed in the latter two categories.

Must Have

• RQ001 - Detect movement towards door
• RQ003 - Speak in a human-like way
• RQ004 - Process spoken natural language
• RQ007 - Alert caretakers

Should Have

• RQ002 - Recognize person with dementia moving towards door
• RQ006 - Play music
• RQ005 - Connect certain concepts
• RQ008 - Recognize PwD leaving the care center
