1. Situated Activities

In this section we will discuss in which environment NAO will be situated. Additionally, we will summarise NAO's concrete functionalities based on phase 1 to phase 3.

Environment(s)

Main subject

• People medically diagnosed with early-stage dementia (henceforth, subjects).

How does the design solution help to solve the problems of a subject with early-stage dementia?

• Through human interactions, NAO helps the subject. 
• NAO achieves a natural flow of conversation between itself and the subject.
• The subject is accustomed to the presence of NAO and is comfortable to ask questions and have a conversation.
• NAO's primary goal is to be able to answer questions about the subject's relatives.
• In the extension phase, additional features implemented for more types of conversation and to become more of an assistant. 

In what environment can NAO be implemented?

• NAO will be stationed in a room where the subjects spend most of their day.
• NAO also exists in the 'online' world, in the sense that the guardian can access and update the NAO's encyclopedia.
• In the extension phase, an additional feature could be that the subject can have conversations with NAO in multiple rooms by connecting to a Google Home and speaker system.

Activities

Phase 1

• The guardian of the subject fills out a form with questions about the subject's relatives.
• NAO will have its first conversations with the guardian to populate the encyclopedia.
• The guardian will place NAO will be placed in the room where the subject spends most of their time, with consent of the subject.

Phase 2

• The subject learns how to activate NAO.
• The subject accustoms to NAO's presence.
• The subject asks questions to NAO, similar to questions asked in the set-up form. These questions have been thought of by the project group.

Phase 3

• The subject activates NAO.
• The subject has a natural flow of conversation with NAO and is able to ask questions.
• The guardian updates NAO's encyclopedia through a web-interface.
