[NJTechDiv] about using NaviLens

[Mario Brusco]

Tracy, I am responding separately because I accidentally deleted your
question email; with an AI generated response:

No, the NaviLens app on iPhone does not use the front-facing camera. It
is designed exclusively to use the rear-facing (main) camera for
scanning NaviLens codes from a distance, up to 60 feet away, at wide
angles up to 160 degrees, and without needing to focus, making it
suitable for navigation and object identification in real-world
environments. All official documentation, app descriptions, and user
guides emphasize pointing the device's camera toward external tags or 
signage, which aligns with rear camera functionality.

There is no built-in option within the app's settings or interface to
switch to the front-facing camera, as this would defeat the app's core 
purpose of long-range code detection (the front camera lacks the
necessary resolution, field of view, and low-light performance for
effective scanning). If you need to scan something in front of you
(e.g., held close), hold the iPhone screen facing you and the rear
camera pointing outward toward the code. For accessibility, the app
integrates with VoiceOver and provides audio/haptic feedback to guide
aiming without visual confirmation.

If this doesn't meet your needs, consider contacting NaviLens support at
support at navilens.com for potential future updates or workarounds, or
explore alternative apps like Seeing AI (which supports front camera for
some features but uses rear for object/code scanning).
