1. Situated Activities

Environment(s)

Main subject (henceforth, person with dementia; PwDs)

• People medically diagnosed with early-stage dementia.

How does the design solution (henceforth, the system) help to solve the problems of a PwD with early-stage dementia?

• Through human interactions, the system helps the PwD. 
• The system achieves a natural flow of conversation between itself and the PwD.
• The PwD is accustomed to the presence of the system and is comfortable to ask questions and have a conversation.
• The system's primary goal is to be able to answer questions about the PwD'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 the system be implemented?

• The system will be stationed in a room where the PwDs spend most of their day.
• The system also exists in the 'online' world, in the sense that the guardian can access and update the the system's encyclopedia.

Activities

Phase 1

• The guardian of the PwD fills out a form with questions about the their 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 PwD spends most of their time, with consent of the PwD.

Phase 2

• The PwD learns how to activate NAO.
• The PwD accustoms to NAO's presence.
• The PwD 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 PwD activates NAO.
• The PwD has a natural flow of conversation with NAO and is able to ask questions.
• The guardian updates NAO's encyclopedia through a web-interface.
