A Quick Tour Of The Leap Motion Touchless Input Device

Novelty fades quickly. While we have become used to touch screens, the latest fad are touch-less interfaces. Game consoles have long embraced natural interaction and even your webcam can detect motion and gestures to some degree. Right now the first application driven gesture recognition devices for personal computers are hitting the market, most notably the Leap Motion.
The Leap Motion Controller is a novel user interface device for Windows and Mac. It lets you control your computer through finger gestures painted into the air above the small device. Leap Motion promises to make interaction with the computer and software more natural. In this article I will take you through the initial setup, introduce you to the Leap Motion’s app store, and generally explore how intuitive and useful this gadget really is.

The Package

The Leap Motion is available for $79.99 plus tax and shipping through the Leap Motion Store. And this is what you will receive:

• The controller,
• two USB cables, a short and a long one, and
• some basic documentation.

Setting Up The Leap Motion Controller

When you first connect the Leap Motion Controller to your computer, you need to run the Windows or Mac setup. The files can be downloaded from the Leap Motion Setup page. While the software is downloading, you can watch a video that demonstrates the entire setup procedure.

After the software was installed, a splash screen loads, which will guide you through the rest of the super quick setup. Basically, you need to connect the controller to your computer and place it in a suitable location, as pictured below.

From there you will be directed straight to Airspace, the Leap Motion’s home screen and marketplace. To enter, you first need to set up your account. Before you are let onto your Airspace Home screen, the place where all your apps are listed, you will be taken through an orientation. Here you will complete several demonstration exercises to familiarize yourself with the Leap Motion Controller.

Amazingly, the Leap Motion Controller can detect single fingers, all 10 of them.

Airspace Home

After you completed the orientation, you will be dropped off at the Airspace Home screen. Here you will find a couple of default apps, including Google Earth, and a link to the Airspace Store. The store will launch in your default browser.

The next time you boot your computer and want to play with the Leap Motion, you can access the Airspace Home screen through the green bar in your system tray. The bar shows up whenever the Leap Motion Controller is connected to your computer and ready to go. Right-click on it and select Launch Airspace. Should there be a problem with the controller, the bar will change its color and display a warning.

Leap Motion Apps Via Airspace Store

Leap Motion worked closely with developers to make sure a selection of cool apps would be available at launch. You could say they succeeded as the Airspace store contains dozens of apps in a handful of categories, including creative tools, education, games, science, and productivity and utilities. However, not many apps are free.

When you get an app, it will immediately appear as downloading on your Airspace Home screen.
Most of the free apps are cute proof-of-concept or training apps, for example VIZ.it (Mac), with which you can draw patterns or play Cut the Rope, a physics game that has won several game awards on other platforms, but with the Leap Motion it mainly allows you to practice precise finger movements.
My favorite non-game app is Corel’s Painter Freestyle. The app was easy to control with finger gestures and thus a lot of fun to use. While it did work very well, it sometimes required a little bit of patience as colors, brush sizes, and other changes are activated in a time-sensitive manner.

Challenges With The Leap Motion

The technology used by the Leap Motion Controller is in its infancy and early adopters will have to tolerate a couple of shortcomings.

• Inaccurate Input: I found it very hard to make accurate moves and thus control my computer. This may be due to the Leap Motion’s incredible precision, which is unmatched by my own clumsy finger movements. Particularly the Touchless for Windows app was more of a drag than an actual help and I was never able to properly use The New York Times app.
• Finger Detection: When I tried to point with one finger, the controller would often detect a second finger somewhere, no matter how well I tried to hide the other fingers. My hand movements became very artificial and anything but intuitive.
• False Positive Malware Detection: Several of the apps I installed were flagged as malware by my antivirus program. Of course that’s a false positive, but it’s worth to be noted.

Tips For Better Working With The Controller

The Leap Motion controller comes with some default settings which you should customize for optimal results. In the system tray, look for the Leap Motion Controller icon and double-click it to launch Settings. If you ever have issues with your controller, you can switch to the Troubleshooting tab and consult the support material or run diagnostic testing.
There are several default settings you might want to to customize:

• Enable Automatic Power Saving: When I worked with the Leap Motion controller, I noticed that it became pretty warm and my computer was more busy than usual. If this bothers you, you can enable automatic power saving, which reduces performance and conserves power whenever possible.
• Change Interaction Height: The default is set to 20cm, which is on the high end. I played with different heights and in the end selected automatic interaction height.
• Tracking and Low Resource Mode: On my relatively new laptop, the Leap Motion worked just fine. On an older machine, however, it froze and apps wouldn’t load. When I disabled tracking and enabled low resource mode (under Troubleshooting), it performed much better.
