Description |
|
| The Visual Interaction Platform (VIP) is an augmented reality system that enables different natural interaction techniques such as writing, sketching, manipulating and navigating in 2D and 3D data. It is an extension of the BUILD-IT system. |
|
| The VIP uses a LCD projector to create a large computer workspace on a horizontal surface on which a Wacom UltraPad A2® digitizer tablet is positioned. |
|
| UltraPad can accurately record digital pen movements and allows the user to perform precise actions in the horizontal workspace, thus making it a combined action and perception space. Precise actions are necessary for handwriting, drawing and sketching. |
|
In addition, the platform is equipped with an ultrasonic wireless position (6 DOF: 3 translation and 3 rotation) tracking device of InterSense ,which extends the 2D action-perception space to the 3D interaction space above the table. |
|
| The system also contains an infrared light source and a camera located above the table. |
|
| This allows the system to track physical objects, such as small bricks, (BEL) that are coated with infrared-reflecting material. |
|
| The platform is equipped with two computers. An Intergraph® workstation is used for visualization, while a Dell OptiPlex GX1 is used for gathering the data from IS600 and camera. Both run Microsoft windows operating system. We use Microsoft Visual C++ as the software development tool. For visualization and image analysis we use OpenGL VTK and Intel OpenCV libraries. |
|
| VIP 1 aims to gather all the required components in order to get everything to work. It is seen as a laboratory prototype. |
|
| VIP 2 is much more “ product like”. It is compact, transportable and works with optical tracking. |
