In the tech world, “making the world a better place” has become a bit of a cliché. But with over a billion people living with some form of disability or impairment, medical technology can make a huge difference in people’s everyday lives. That’s why Virtualware is using Leap Motion technology to help people recovering from strokes, Parkinson’s Disease, and more.

Put simply, VirtualRehab Hands is a mini-gaming platform that lets doctors monitor the progress of patients from anywhere in the world. The games are fun and simple, using Leap Motion’s highly responsive hand tracking technology to let patients control game elements on the screen. According to Virtualware, their system is the very first virtual rehabilitation software to be classified as a medical device, under the EU’s Medical Device Directives. It joins TedCas and MotionSavvy in bringing Leap Motion technology to the assistive healthcare space.

Over the next few years, billions of devices are going to spill onto the Internet and rewire our world in ways never before thought possible. Alongside augmented and virtual reality, the Internet of Things has the potential to change the world and how we see it.

That’s why with this year’s 3D Jam we created an Open track for desktop and hardware projects – opening the doors to experiments that build on the bleeding edge of this emerging space. In this post, we’ll look at some incredible past projects, plus some key resources and tutorials that will take your hardware hack to the next level.

Before we dive in, there are two things you should know. First, before you start building for the 3D Jam, please check out our approved hardware list. We’re open to hardware requests, but we want to make sure that we can judge your submission fairly. Second, you’ll need a computer to run the Leap Motion core software. This is because there’s a lot of image processing and math happening under the hood, and popular boards like the Raspberry Pi or Arduino just don’t have the necessary horsepower. With that out of the way, let’s have some fun!

Sci-fi movie interfaces are often breathtaking ways to tell a story, but the next generation of AR/VR interfaces will be clearer and easier to use – with a lot less visual clutter. This week, motion designer Mike Alger released an 18-minute video that digs into the cutting edge of VR interface design using the Leap Motion Controller and Oculus Rift.

As humans, we can use our existing instincts and ways of seeing the world to our advantage. In his video, Mike explores several beginning design considerations related to zones for content, types of interaction, and interface design methods. Moving from button interaction design to a proof-of-concept VR operating system, he carefully navigates the divide between reality and digital fiction.

Developers around the globe have until Nov. 9th to build the most amazing experiences for virtual reality, desktop, mobile, and beyond – with over $75,000 in cash and prizes up for grabs. Register for the 3D Jam now at


On your mark, get set, GO! This morning, our second annual 3D Jam kicks off with developers around the world competing for over $75,000 in cash and prizes – building brand new experiences for virtual reality, desktop, mobile, and beyond. Submissions are now open at

With over 150 complete experiences submitted to last year’s 3D Jam, we saw everything from sci-fi space stations to the inner workings of the human body. Virtual reality experiences dominated the field, representing 14 of the top 20 and taking all three finalist spots. This year, developers have registered from over 80 countries around the world – twice the number from last year! We’ve also switched up the 2015 competition with two tracks: AR/VR and Open. The AR/VR track covers experiences built on tethered HMDs like the Oculus Rift, while the Open track covers desktop, hardware hacks, and the Internet of Things.

Over the next six weeks, developers will be racing the clock to get their projects on by November 9th at 11:59:59 pm PST (full contest rules here). Registrations will remain open until the submission deadline. If you haven’t already, we encourage competitors to register and get their hardware as early as possible. Everyone who registers gets a special discount code for our web store, and teams with complete submissions get refunds for the cost of their hardware.

Development Resources

We’ve made some huge advances since the 2014 Jam, with new resources and integrations that will take your projects to the next level. (You can read our development guide for a full breakdown of our top resources and best practices.) Our Core Assets for Unity now feature:

On the Unreal side, we’re collaborating with the enormously talented getnamo to bring new assets to his community plugin. Right now, the plugin includes full support for Unreal 4.9.1 and VR, with Image Hands on the way. Stay tuned to our community forums for updates.

Hardware hackers also have access to more resources as the Internet of Things continues to grow. Integrations like Cylon.js and Vuo are making it easy for developers, designers, and artists to bridge the divide between people and technology in new and exciting ways. If you’re looking to submit a hardware project on the Open Track, be sure to check out our approved hardware list.

We can’t wait to see how you push the frontiers of technology with Leap Motion interaction. Touch base with your fellow jammers with the hashtag #3Djam, follow us @LeapMotion on Twitter and Facebook, or join the conversation on Reddit. Check out our community forum thread to find team members and get the latest updates. Good luck!

With the 3D Jam just around the corner, we thought we’d give you a headstart – with a full guide to the very latest resources to bring your to life. In this post, we’ll cover everything you need to know about our integrations and best practices for augmented and virtual reality, desktop, and the Internet of Things.

A quick note: VR/AR is a rapidly emerging ecosystem, and many of the engine tools and features that we use to build our Unity and Unreal assets are constantly shifting. We have major updates for these assets in the works, so stay tuned!

What makes a collection of pixels into a magic experience? The art of storytelling. At the latest VRLA Summer Expo, creative coder Isaac Cohen (aka Cabbibo) shared his love for the human possibilities of virtual reality, digital experiences, and the power of hugs.

Isaac opens the talk by thinking about how we create the representation of 3D space in the digital world of ones and zeros – a place where nothing really exists, but everything is possible. Just connecting a series of one-dimensional dots can create a line, a plane, a fractal, or even things completely outside our everyday understanding.

When the Leap Motion Controller made its rounds at our office a couple of years ago, it’s safe to say we were blown away. For me at least, it was something from the future. I was able to physically interact with my computer, moving an object on the screen with the motion of my hands. And that was amazing.

Fast-forward two years, and we’ve found that PubNub has a place in the Internet of Things… a big place. To put it simply, PubNub streams data bidirectionally to control and monitor connected IoT devices. PubNub is a glue that holds any number of connected devices together – making it easy to rapidly build and scale real-time IoT, mobile, and web apps by providing the data stream infrastructure, connections, and key building blocks that developers need for real-time interactivity.

With that in mind, two of our evangelists had the idea to combine the power of Leap Motion with the brains of a Raspberry Pi to create motion-controlled servos. In a nutshell, the application enables a user to control servos using motions from their hands and fingers. Whatever motion their hand makes, the servo mirrors it. And even cooler, because we used PubNub to connect the Leap Motion to the Raspberry Pi, we can control our servos from anywhere on Earth.

As the 3D Jam approaches, developers around the globe are already getting a headstart on their projects. Zach Kinstner, the creator behind Hovercast and Firework Factory, has been sharing his latest project through a series of videos – a virtual reality guitar! We caught up with Zach this week to talk about his design process, especially the guitar’s unique combination of visual depth cues.
