According to Amazon's Camera description page.
When combined with the DualShock 4 Wireless Controller's light bar, the evolutionary 3D depth-sensing technology in the PlayStation Camera allows it to precisely track a player's position in the room. From navigational voice commands to facial recognition, the PlayStation Camera adds incredible innovation to your gaming.

Games Asylum: "Even though the Vampire Survivors influenced ‘auto shooter’ genre isn’t long in the tooth, I’m still surprised that it has taken this long for a Roman gladiator-themed rendition to come along – especially with a sequel to Ridley Scott’s 2000 box office hit Gladiator imminent.

It would be kind of funny if this is true as a whole press conference was based around this feature and Sony have stayed silent on the matter as if its only vaguely important (it really is imo). I think the most intuitive way to browse the menus and UI could end up being the touch pad. If not though, analog sticks have never failed me.
Any new features is a bonus for the PS4. This feature is not one I would use myself but it could be cool for Netflix or something to navigate the browse page.
