Interestingly, it can track each finger (if not always 100% accurately) pretty well, even when some are partially occluded. As seen in the first two images in this writeup, it almost appears as if it’s using some sort of augmented reality X-ray device. I first chose V4, and after a calibration, was able to get it working with a demo program that tracks your hands and fingers. There’s a V4 version of the software, as well as a V2 version for legacy desktop apps.
Navigate to /setup, as noted on the device’s peel-off covering, where you’ll be greeted with a desktop and VR option. It also has issues with bright lighting, so make sure to take that into account during setup. Anecdotally, I found that the shorter cable, with presumably less resistance, seemed to work better. Hardware installation is as simple as plugging it in, but its documentation notes that it doesn’t always work well with a hub, per power requirements (more on this later). The Leap Motion comes in a rather unassuming box, with the unit itself, along with two USB-A to Micro USB 3.0 cables. Leap motion tracks open and closed hands See related product Can a sensing setup shaped like a large thumb drive, at a cost of less than $100, actually deliver ten-finger, hand, and arm tracking? Let’s find out: Such a device, however, seems almost too good to be true. While those goals seem loftier than the promise of VR presented in 1992’s Lawnmower Man, all of this is actually a reality, and has been for several years, in the form of Ultraleap’s Leap Motion Controller. You’d also want it to be small enough to unobtrusively fit on a desk, or even be attached to a headset.
Ideally, what you need for a truly immersive VR experience is a device that tracks your hands and fingers without any sort of controller, or even gloves. With ten fingers, there’s a lot more going on than can be described with one or two blunt instruments. However, the reality of our human experience is that we don’t always have a tool in-hand. This works well if you’re playing a shooting game, or perhaps performing sim-gardening with a trowel or two. These track both your hand positions and act as a trigger for whatever action you need to perform. Besides having to actually put on a headset, VR experiences generally require some form of handheld controller or controllers.
