Archived - Intel® RealSense™ Navigation Library Sample Code

By Joseph K Olivas, Bryan Andrew Mackenzie, Published: 08/03/2015, Last Updated: 08/03/2015

The Intel® RealSense™ SDK has been discontinued. No ongoing support or updates will be available.

If you've used the Food Network* hands free navigation provided by the Intel® RealSense™ Experience for Web Browsers you've seen how easy no-touch navigation can be added. 

Intel has published the Intel® RealSense™ Navigation Library to make it easy to control web applications via gestures and voice commands.

The sample code provides an interface to the Intel® RealSense™ SDK for Web and includes code to:

  • Query if the system is Intel RealSense technology-capable and up to date (has runtime and DCM) & query for supported web browser.
  • Play/pause a video or select hyperlinks and other page elements using gestures (pinch, hover, tap) or voice commands.
  • Add custom Commands ("Hello"  and "monkey") to the default dictionary list of “page up”, “page down”, “scroll up” and “scroll down”. 
  • Add custom Alerts ("woohoo"  and "you said something").

    Browsers listed for support are Chrome*, Firefox* and Internet Explorer* (11 and up);  but like everything else in the code, can be easily expanded.

The sample code performs these basic steps:

  • Run dependency checks
  • Create an instance of the navigation library and a reference to the content object.
  • Add a user defined element and its callback for the given event (tap gesture).
  • Define the list of commands (in addition to the defaults) and a callback.
  • Initialize the navigation library (create the navigation elements for scrolling and initialize the gesture and speech modules of the Intel RealSense SDK.


Download the libraries and sample code from GitHub*.
