Is this surveillance of students?

No. The default mode reports aggregate engagement signals across a cohort, not per-student tracking. Per-student analysis requires explicit institutional and student opt-in with appropriate consent language.

What does 'engagement' actually measure?

A weighted blend of facial-attention indicators, positive-affect signals (AU6, AU12), concentration markers (AU4), and overall expressivity — not a single emotion label. The result is reported on a 0–100 scale relative to the cohort's baseline.

Will the system work with younger students?

Mental Edge's core models are validated on adolescent and adult faces. For pediatric research, the underlying FACS framework has a Baby FACS variant; contact us about pilot use cases.

How does it handle students who turn cameras off?

The system processes only visible faces. Students who opt out by disabling their camera are simply excluded from that session's analytics — there is no penalty or flagging.

Can we use this for online courses?

Yes. Mental Edge works with any recorded video source, including async course recordings, live webinars, and synchronous online classes.

What does it cost for a department or institution?

Pro + Analytics is $129.99/month per seat. Departmental and institutional licensing is available — contact info@mentaledge.ai.
