Expression recognition in messaging systems

A computer device comprising at least one processor in communication with at least one memory device, wherein the at least one processor is programmed to:

• monitor a video feed provided by one or more cameras of the computer device to detect a biometric signature of an operating user;
• detect a facial profile based on the detected biometric signature and match the detected facial profile against a known facial profile utilizing a facial recognition process to verify an identity of the operating user;
• determine a plurality of human expressions based on the detected biometric signature utilizing an expression recognition process and associate each human expression of the plurality of human expressions with a contextual tag to generate a plurality of contextual tags;
• generate a user profile in a user profile database based on the plurality of human expressions and the plurality of contextual tags;
• determine a current activity for the computing device;
• associate the current activity for the computing device with one of the plurality of contextual tags;
• and
• update the user profile in the user profile database based on the association.

A smartphone comprising at least one processor, at least one camera, at least one machine-readable storage medium, and software or firmware stored in the at least one machine-readable storage medium, the software or firmware including a messaging application, wherein the at least one processor is programmed via the software or firmware to:

• monitor a video feed from the at least one camera to detect a facial profile of an operating user when a messaging interface of the messaging application is actively being used;
• match the detected facial profile against a known facial profile utilizing a facial recognition process to verify an identity of the operating user;
• determine a plurality of human expressions of the operating user based on the video feed and an expression recognition process;
• associate each human expression of the plurality of human expressions with a contextual tag to generate a plurality of contextual tags;
• generate a user profile in a user profile database based on the plurality of human expressions and the plurality of contextual tags;
• determine a current activity for the smartphone;
• associate the determined current activity for the smartphone with one of the plurality of contextual tags;
• and
• update the user profile in the user profile database based on the association.
