User state selection based on the shape of the exhale stream
First Claim
1. A system configured to select a state of a user, comprising:
- at least one inward-facing head-mounted thermal camera (CAM) configured to take thermal measurements of at least three regions below the nostrils (THS);
wherein THS are indicative of shape of the exhale stream (SHAPE); and
a computer configured to select the state of the user, from among potential states of the user, based on THS.

Abstract
The three-dimensional (3D) shape of the exhale stream from a user'"'"'s nostrils is often correlated with the user'"'"'s state (e.g., an emotional state and/or a certain health condition). Thus, identifying the shape of a user'"'"'s exhale stream can help determine the user'"'"'s state. In one embodiment, a system that selects a state of a user includes at least one inward-facing head-mounted thermal camera that takes thermal measurements of at least three regions below the nostrils (THS). THS are indicative of shape of the exhale stream (SHAPE). The system also includes a computer that generates feature values based on THS, which are indicative of the SHAPE, and utilizes a model to select the state of the user, from among potential states of the user, based on the feature values. Optionally, the system includes a user interface that present the user'"'"'s selected state.

13. A method for selecting a state of a user, comprising:
-
taking, using at least one inward-facing head-mounted thermal camera (CAM), thermal measurements of at least three regions below the nostrils (THS);
wherein THS are indicative of shape of the exhale stream (SHAPE);generating feature values based on THS;
whereby the feature values are indicative of the SHAPE; andutilizing a machine learning-based model for selecting the state of the user, from among potential states of the user, based on the feature values. - View Dependent Claims (14, 15)

16. A system configured to detect the shape of exhale stream, comprising:
-
at least one inward-facing head-mounted thermal camera (CAM) configured to take thermal measurements of at least three regions below the nostrils (THS) of a user;
wherein THS are indicative of the shape of the exhale stream (SHAPE); anda computer configured to detect the SHAPE based on THS and a machine learning-based model;
wherein the machine learning-based model was trained based on previous THS of the user. - View Dependent Claims (17, 18)

19. A system configured to present a user'"'"'s state based on shape of the exhale stream (SHAPE), comprising:
-
at least one inward-facing head-mounted thermal camera (CAM) configured to take thermal measurements of at least three regions below the nostrils (THS); wherein THS are indicative of the SHAPE; and a user interface (UI) configured to present the user'"'"'s state based on THS; wherein, for the same breathing rate, the UI presents different states for the user when THS are indicative of different SHAPEs that correspond to different potential states. - View Dependent Claims (20)
