e. Functions

The overall objective of the human-AI system is for the AI to aid humans in overcoming challenges faced by them due to their medical condition of dementia. 

Human and AI collaborate through interacting with each other. The AI system is designed with the help of existing knowledge around the needs and challenges of dementia patients. In interacting with the human it supports, the AI personalizes to the human's preferences by analyzing their behaviour patterns. This could also be aided by other caretakers who can configure the robot with preferences of the patient.

The functions of the AI system:

- provide an interactive, conversational interface for dementia patients and their caregivers

- support various activities for different challenges faced by dementia patients 

- adapt for personalized use

- analyse interaction data to infer dementia patients' condition and anomalies

- notify caregivers 

Inputs:

- Initial training data

- Personalized configurations provided by caregivers

- Usage analytics by dementia patients

Outputs

- Activities like games, interactive storytelling

- Chat

- Personalization

- Notifications

The AI interacts with the human by suggesting activities and engaging in conversation. The human provides inputs and feedback by responding to these suggestion in the form of clicks, indicating preference for activities.

Further, if the human engages in an activity, say, one where the AI tells an interactive story, the human provides input by selecting a particular option when faced with a choice, indicating their preferences.
