and wake. To improve the power efficiency of the
Intel® RealSense™ ID Solution
F450 system, it is recommended that the host system implement either motion or
proximity sensing capabilities to determine when to wake and start a Face
Authentication session. The host system would receive an interrupt from the user
approach sensors and then propagate that request to the
Intel® RealSense™ ID
Solution F450 module interface which will cause a wake event.

User Feedback
If the system design requires both audio and visual feedback the host will need to
interface to both speaker and/or display/LED components. This will provide the
necessary user feedback during enrollment and authentication scenarios. It is up to
the host system to define each audio and visual prompt.
As the enrollment and authentication flows are initiated by the host system, the
Intel® RealSense™ ID Solution
F450 module can return status codes. It is up to the
host system to translate those codes into respective audio or visual feedback which
can cause the user to perform certain actions.
