WallFrame is envisioned as a high level framework for creating, managing and deploying interactive applications on Large Scale Wall Displays. WallFrame brings together several core elements and some elegant wrapping to provide an easy path to developing applications for natural interaction with wall displays:

• Middleware from OpenNI and NITE to provide full 3D user tracking of up to 6 individuals. This middleware is compatible with the Microsoft Kinect, ASUS Xtion Pro or other commercial depth sensor.
• The Qt Framework for easy authoring of graphical user interfaces, and the easy management of windows across the multiple displays of a display wall
• OpenGL, via Python PyGL or with OpenSceneGraph C++ wrapper for 3D application authoring
• The Robot Operating System, which allows for the easy and efficient connection of modular software components
• The WallFrame Core Libraries consist of a set of simple abstraction layers and tools to develop applications:
• A user manager which publishes user interaction data (including 3D pose, gestures, events) to applications or widgets
• An application manager to easily launch and manage applications from an intuitive and customisable menu interface
• Tools for notifications and debugging
• Base applications written in Python and C++ that can be inherited to provide direct access to user data and other resources, as well as display application data seamlessly across multiple displays
• Simple configuration files (using ROS and YAML) for changing application parameters without compiling
• A set of sample applications
