OSVR hacker dev kit to include motion control with embedded leap motion technology

The optional OSVR faceplate with Leap Motion will be the first input technology to be offered for the platform
SAN FRANCISCO – Leap Motion and OSVR today announced that the OSVR Hacker Dev Kit will have an optional faceplate with Leap Motion’s hardware and software embedded, making the HDK the first-to-market virtual reality headset with natural motion control technology integrated into the head mounted display. By merging the speed and accuracy of Leap Motion’s hand tracking with the growing OSVR ecosystem, users will be able to create and interact with a wide range of supported content.

“By letting the user connect directly with the VR environment, hand tracking allows virtual reality to be as natural and intuitive as interacting with the real world, giving the user a powerful sense of presence and immersion,” said Michael Buckwald, CEO and Co-founder of Leap Motion. “We’re pleased to partner with OSVR to bring our technology to the OSVR Hacker Dev Kit, helping developers enable the true potential of VR.”

3D Output Meets 3D Input

The OSVR faceplate with Leap Motion will include the embedded Leap Motion hardware and the OSVR motion plugin software. Integrating natural, controller-free motion tracking with a virtual reality headset marks an industry milestone. The OSVR partnership is the first in a future lineup of head mounted displays that will feature Leap Motion’s technology built in.

The importance of embedding motion control technology is twofold: developers can write code for a single platform that works across multiple hardware devices, and consumers get a consistently smooth experience. The integrated OSVR motion plugin enables support for multiple motion device types, in addition to Leap Motion.

Open and Extensible

Leap Motion developers will be able to easily extend their existing Leap Motion VR applications into the OSVR framework. New developers that want to incorporate fundamental 3D motion input can count on a standard set of functions, such as six-degrees of freedom inputs (move in X, rotate around Y), and write experiences that are device agnostic. Leading game engines such as Unity and Unreal will be supported.

Developers can also utilize the OSVR Imager Interface which provides access to the Leap Motion Image API. Developers can include video pass-through for other applications, opening up a wide range of possibilities for computer vision apps.

“OSVR brings game developers, gamers and hardware manufacturers together to solve challenges and make VR gaming a reality for the masses. The highly modular OSVR Hacker Dev Kit plays a crucial part in that equation, allowing any kind of technology to be easily added to the HDK.” said Christopher Mitchell, OSVR. “The Leap Motion faceplate is a great example of how immersive natural interactions in VR can be brought to developers and gamers alike.”

Product Availability

Developers worldwide can pre-order the HDK and the OSVR faceplate with Leap Motion through the OSVR web store in May; shipping will begin in June. Announced at CES 2015, OSVR is in the early stages of development. The OSVR platform supports a broad range of input devices, though Leap Motion will be the first motion-tracking technology to be integrated into the OSVR Hacker Dev Kit to provide hand tracking for a truly compelling and intuitive VR experience.

This opens up exciting possibilities for Leap Motion’s growing developer community, which includes over 160,000 developers in more than 186 countries. Following the 2014 launch of Leap Motion’s V2 tracking software, capable of tracking individual joints and accounting for finger occlusion, the company continues to release significant software updates bimonthly. Developers can visit developer.leapmotion.com to ensure they have the latest build.

A brief overview of the OSVR software repositories

The OSVR team opened up most of the source code repositories to the public this weekend, and a few additional repositories will be opened in the coming days.  Many have asked us for a brief overview of the project.

The best place to start is osvr.github.io. If you haven’t read the ‘introduction to OSVR whitepaper‘ you might want to do so.

There are several github projects under the /osvr organization. They are as follows:

Key projects:

  • OSVR-Core : this is the heart of the project. The OSVR_server executable connects the game to the OSVR hardware and software components.


  • OSVR-Tracker-Viewer is a utility that graphically shows the position and orientation of the head and hand controllers. It is also an OSVR client, and thus an example on how to connect to and extract data from the server
  • Distortionizer: a utility to estimate distortion correction parameters for various HMDs and a shader to implement the parameters estimated by the Distortionizer. OSVR has JSON descriptor files for HMDs (and many other objects) and the distortion parameters are part of that JSON file

Game engine plugins:

  • OSVR-Unity includes a prefab component that can be imported into Unity.
  • OSVR-Unreal (to be released later this week) is an Unreal Engine plugin

Development tools:

  • OSVR-Boxstarter is a Boxstarter install that helps quickly set up a development environment on a Windows machine
  • OSVR-JSON-Editor is the source code for a tool (deployed version here) that helps create and edit the JSON descriptor files
  • OSVR-JSON-Schemas is a repository for such JSON files


  • OSVR-Oculus-Rift provides a plugin that allows using the position and orientation data of an Oculus device inside OSVR.
  • OSVR-Vuzix (to be released later this week) does the same for Vuzix headsets
Additional projects are coming. There is also a wiki page. Issues are currently tracked as part of the Github pages of the projects and we are looking to add an open-source project management tool.
OSVR (licensed under Apache 2.0 license) aims to create a multi-platform framework to detect, configure and operate a wide range of VR devices as well as to allow smart plugins that turn data into useful information. This is a big undertaking and there is a lot more work to be done to fulfill that vision, so we are looking for all the help we can get. We are super encouraged by the support and feedback we are getting from developers all over the world that believe in the open-source concept, and want to make their contributions towards moving VR forward.
Let us know what you think. What’s missing, what your priorities are and how we can get you involved. Welcome to OSVR.

OSVR now open to the pubilc on Github

The OSVR project is now open to the public. All key software projects are now available and a few minor ones will be added in the next couple of days.

The best place to start is http://osvr.github.io/

Please also make sure to visit the Wiki, support portal, development blog and other OSVR sites available from the top right menu in http://osvr.github.io/

Distortionizer tool, Imager interface, Unity improvements

Several new capabilities of OSVR are now available to the OSVR ecosystem, including new features in the core, improved Unity plugin, distortion measurement/correction tools as well as additional new resources available to the community.


A new release of OSVR core (version 0.1.652) has been deployed to access.osvr.com

The release adds several new features:
– Add display descriptor JSON files that describe display parameters such as field of view, resolution, side-by-side mode as well as distortion correction parameters. These files can be used by various applications – such as the Unity plugin – to adjust the rendering parameters to match the VR headset of choice. If you make HMDs, please take a look at the format of the JSON file and send us one for your device.
– Add automatic reconnect for OSVR HDK and Razer Hydra. This eliminates the need to restart the OSVR server if the HDK or Hydra were power cycled or otherwise disconnected from the PC. A more generic mechanism covering additional devices is coming soon.
– Allow controlling the sleep period in the main loop of the server, thus freeing up CPU resources. The osvr_server_config.json file now has a “sleep” parameter under “server”. This parameter, in milliseconds, specifies the sleep in the main loop. It can be 0 (maximum performance, maximum CPU load) or other values such as 1 (samples peripherals every 1 mSec, so 1000 times per second).

Imager Interface

This release also includes an alpha version of the new imager interface which allows routing and processing of video images inside OSVR. It is built on OpenCV, the popular open-source computer vision framework.

The imager interface includes PluginKit and ClientKit interfaces (both are designed for use with C++ though there is an underlying C API). An OpenCV camera capture plugin (with sample config file) and sample client application (displays image data from OSVR using OpenCV “highgui”) are included.

In its current incarnation, the imager interface has significant limitations with regards to image size, number of bits per channel and the efficiency of image transfer between the OSVR server and OSVR clients. These limitations will be addressed shortly. The imager interface includes a lot of infrastructure work which will be used in additional types of device interfaces.

OSVR Unity Plugin

The Unity plugin (version 59) has been improved significantly. It automatically sets the display parameters based on the display JSON files (see https://github.com/OSVR/OSVR-Unity/tree/master/OSVR-Unity/Assets/OSVRUnity/Displays for some examples)

We also created a new white paper showing how to transition Unity games to OSVR. Download it here

Distortionizer Tool

This tool provides a way to empirically determine geometric and color distortion parameters for an HMD as well as an example shader that uses these parameters to correct them. It is found in https://github.com/OSVR/distortionizer

A utility program allows interactively changing the distortion of red, green and blue using a simple cubic distortion function until the image appears best. It then stores these parameters in a JSON file and includes a demonstration program that uses them in a shader. Although the tool can be enhanced for more sophisticated functions, we believe it is useful in its present form.

What’s Next?

In the coming days, towards the close of GDC, we shall open the source code for public consumption. Until then, we are busy making some improvements and adjustments including documentation improvements, formally changing the software license to Apache 2.0. We are also working with many contributors to add plugins and other unique functionality to OSVR. Stay tuned!

Some Housekeeping

A few administrative notes:

– We will be at GDC, primarily at the Razer booth which is booth 602 in South Hall. We’ll have exciting demos from partners and will be available to discuss anything OSVR.
– The wiki pages at access.osvr.com have been updated to include several ‘getting started’ documents, so make sure to take a look from time to time.
– The Github repositories were migrated from the /sensics organization to the /osvr organization on Github
– The best email address for support is support@osvr.com

We look forward to your comments and feedback. Any questions or issues? email support@osvr.com
