With its next venture into the gadget world, Nissan wants to get on your face. Ahead of the Tokyo auto show, the automaker has released a David Fincher-esque teaser video for its head-mounted HUD, the 3E. Given how its smartwatch is specifically tailored for race car drivers -- displaying vehicle performance analysis, the driver's vital signs and social media presence -- we don't expect much different from this wearable. In theory, this could be a cheaper way to implement heads up displays that are better at keeping you in tune with your ride than traditional dashboard systems. Worried you won't find this gizmo on the the auto show's floor? We're betting it won't be too far away from the equally futuristic Batmobile knock-off.
