Leap Motion Controller review: A Mac controller that you don't touch

Leap Motion Controller review

Want to control your Mac without having to touch it? You can, today. But there are some limitations

Many people have been wondering what Apple will do with the technology they acquired when they bought Primesense, the Israeli developer of the 3D sensor technology Microsoft used in the first Kinect peripheral for the Xbox 360 video game console. That's still anyone's guess. But if you'd like a Kinect-like interface for your Mac, you can buy one today thanks to Leap Motion. How well does it work? Let's take a look.

The Leap Motion Controller measures three inches long. It connects to your Mac using a USB cable, and you lay it in front of your Mac's keyboard. When it's active, the Leap Motion Controller can detect your hand and finger movements and interprets them, working with custom-designed software to understand what you're doing. You can point, you can wave, you can reach for objects on the screen and grab them. Pick them up, move them.

Leap Motion Airspace interface

Setting up the Leap Motion Controller is pretty easy. You plug it in and install a software package from the Leap Motion web site. Airspace is the software that controls the device; it's also the name of the online store where you can download apps designed to support the Leap Motion Controller.

The device itself has sensors that detect your hand and finger motion as you move above it. Settings enable you to customize the height of the "interaction area," so you don't trigger it accidentally, along with tracking priority and other functions.

The basic software doesn't support any sort of built-in emulation of mouse or trackpad movements, so you'll find yourself working within Airspace to get started. There are packages you can download — both paid and free — that enable you to use Leap Motion gestures to interact with the system, however - opening windows, positioning your cursor, clicking on buttons and more. There are about a half a dozen different apps to control your Mac using the Leap Motion Controller.

Controlling the ball in Vitrun using my hand

Predictably, gaming is a huge part of the Leap Motion Controller experience. There are dozens of downloadable games, many free, many others costing only a few dollars, that demonstrate the peripheral's ability to sense motion. One of my favorites, Vitrun Air, plays a bit like Super Monkey Ball, with you pushing, pulling and sliding a ball through increasingly complex and treacherous mazes suspended in space. Famed comic book creator Stan Lee's gotten into the Leap Motion game with Verticus, which puts you in the role of a superhero trying to save Earth from alien destruction.

But games are only one starting point for using the Leap Motion Controller. Developers of educational software have figured out how to use the controller to teach geometry, astronomy, even biology with virtual dissection of things like frogs, tarantulas and human skulls. Creative tools abound with musical composition products, virtual sculpting tools, painting, even a plug-in for Photoshop. You can download a tool that lets you control PowerPoint presentations.

Using the Leap Motion Controller is at once an exhilarating and frustrating experience. It's a lot of fun to be able to control on-screen actions without ever touching your Mac, but I recognized the limitations of the controller fairly quickly. It would occasionally lose track of my hands and fingers, and I'd repeatedly have to reorient my hands in order for it to "see" them again. When this happened in games it was usually at the worst time, and I'd reflexively push or punch or do whatever action I was supposed to even harder to get it to work, usually without success. The Leap Motion Controller can also get confused if there's anything covering the sensor area, or if there's bright, directly light on it.

You'll also likely run out of software to buy or download before too long. Much of the offerings in the Airspace Store are fun, but ultimately novelties — not apps that you're bound to make part of your permanent workflow or come back to again and again because they're fun to use and play.

Having said that, Leap Motion has been steadily improving the quality of the Leap Motion Controller drivers since its inception last year and are focused on bringing more developers on board to create products that support the technology.

The good

  • Small, compact and portable
  • Easy to set up and use
  • Lots of free software to get started

The bad

  • Software tends to run towards novelty as opposed to truly useful
  • No built-in system-level interface management; though free third-party tools are available
  • Occasional inaccurate or altogether nonexistent tracking

The bottom line

At $79.99, the Leap Motion Controller is in the same ballpark as a premium game controller or a Bluetooth keyboard or mouse. While it is a novelty item at this stage, it gives a fascinating peek into the future of gesture-based control on the Mac. If you're looking for a unique way to work and play on your Mac, the Leap Motion Controller might be a good investment.

Leap Motion Controller review: A Mac controller that you don't touch


I guess it can't be a "hands on" review if you keep your hands off of it. :)

I received a complementary device during the developer sign-up and it was buggy and inconsistent at best. They kept sending down firmware updates until I gave it a rest, but not before I canceled my preorder I set up as well.

Months later, I've recently plugged it back in and it seems to be a lot smarter and accurate, but I agree with all of Peter's pros/cons. I tried using Google Earth and just couldn't get the hang of manipulating the space, and most of the other apps and games are as novelty as he says they are. Even trying to use the tool that allows you to move and surf through Safari seemed really cumbersome and unpredictable.

the leap motion controller is inaccurate, apple seriously need to work with ubi interactive to bring their software to the mac app store, before Facebook buys these guys up as well to go with their vr software and oculus rift:


press on the play icon in the middle of the screen to see what this can do!

I preordered the Leap Motion sight-unseen based on the intro videos and hype. While it's a good tool for applications developed specifically for it, it fails miserably at everything else. I realize that it wasn't intended as a "mouse replacement" and I think that's a huge missed opportunity.

I bought one of these things and it's terrible. If they want it to be useful it needs to be able to do UI functions like swipe between spaces, bring up launchpad/mission control, etc. Basically any multitouch function the magic trackpad can do. I tried some of the 3rd party software to accomplish this and it was a mess. Whether it was the software or the awful motion detection, I don't know. Apple should buy these guys and get it done right.

I like the hardware concept, but not another store to have to get software from. Having to wade through windoze software to maybe get to something interesting for the Mac puts me off completely. I like it as a novelty device though....
