HTC Vive Pro's dual cameras can apparently track hand motion

When HTC unveiled its higher-end Vive Pro VR system back at CES, the company was suspiciously quiet about the dual cameras on this VR headset: there were no related demos, and the company reps remained tight-lipped. The smart-ass in me assumed that based on the similar looks, this module was probably a variant of the inside-out tracking sensor on the standalone Vive Focus, while others speculated that it would bring AR capability. Well, today we finally have an answer: it's actually a depth sensor, and it'll apparently enable basic hand tracking without additional hardware. This new bit of information came straight from the horse's mouth. By that I mean HTC Vive's Vice President Raymond Pao, who I bumped into at the company's Shenzhen event earlier this week -- it was celebrating the commencement of the Vive Focus' shipment, as well as introducing the Vive Pro to the Chinese media and partners.
