Short answer

How can I use my AI to track user behavior?

Your agent uses the Face++ MCP to extract facial expressions, hand gestures, and body poses from images. This turns visual data into text-based descriptions of how people are acting. You'll see the specific outcomes below.

The results you get.

Behavioral data outputs.

The AI processes your images into these distinct categories of information.

EMOTION

Facial expression data

The AI identifies specific facial movements. You get a clear sense of the user's emotional state.

GESTURE

Hand and arm tracking

Your agent detects specific hand signals. This helps you understand non-verbal communication.

POSTURE

Body language summaries

The AI maps the physical stance of the subject. You receive a description of their overall posture.

HUMAN

Manual review needed

The AI provides the raw behavioral data. You must interpret these findings to make final decisions.
