Leap motion reddit11/14/2023 We (Don’t) Have the Power!Īfter trying this out, I really think much of the issue with my setup was that my USB hub didn’t have enough power to spare, and my laptop’s single USB-A port wasn’t really up to the job either. You can even find some mention of using Leap Motion with an Arduino via Cylon.js, which presents a wide array of other possibilities. Given today’s focus on keeping surfaces clean, such functionality could be extremely useful. There are also various hands-free computer control applications available for the system. The experience would certainly be better on a VR headset, and with a processor designed for 3D gaming, rather than my laptop. It’s similar to Guitar Hero, or perhaps Beat Saber sans controller, and is pretty fun until your arms get tired. The game really highlights the Leap Motion’s abilities, as it invites you to hit and manipulate notes as they progress toward you through a square corridor. This and other games can be downloaded from Leap Motion's gallery. With that (and some fiddling with the plugs on my Windows 10 computer) I got it to work with the Leap Motion App Home with the Kyoto app, as well as the “TAKT-RHYTHM” game. This was installed, and I applied the hotfix found on their website. V2 Software CompatibilityĪfter having some issues under V4, I decided to try out V2 for its compatibility features. Through this data passed along to your computer or headset, various games and functionality can be controlled. So, it’s not magic, or harmful radiation, but an advanced tracking algorithm. The Leap Motion Service then feeds the results – expressed as a series of frames, or snapshots, containing all of the tracking data – into a transport protocol." Filtering techniques are applied to ensure smooth temporal coherence of the data. "Despite popular misconceptions, the Leap Motion Controller doesn’t generate a depth map – instead it applies advanced algorithms to the raw sensor data… Our tracking algorithms interpret the 3D data and infer the positions of occluded objects. Leap Motion puts it this way in a blog post: The trick here is that it uses two cameras and infrared lighting to track images in stereo to infer three-dimensional input. 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.
