## Face expressions

To make our assistant more conversational, we've integrated face expressions that reflect the feeling of the conversation.

### Owner

Refers to an assistant owner, the one that owns a Cati device at home.

### App user

Refers to a mobile app user, usually a family member of the `owner`

## User connections

Usually, an `app` user connects to an `owner` device to manage the device. When the app user connects, it will show as a contact to the `owner` device.

An `app` user can be connect to multiple `owners` (for example, a son may connect to the assistant of both of his parents).

An `owner` device can be connected with multiple `app` users (for example, it could connect to multiple family members).
