Basic Principles of ARToolkit – The camera captures video of the real world and sends it to the computer. – Software on the computer searches through each video frame for any square shapes. – If a square is found, the software uses some mathematics to calculate the position of the camera relative to the black square. – Once the position of the camera is known a computer graphics model is drawn from that same position. – This model is drawn on top of the video of the real world and so appears stuck on the square marker. – The final output is shown back in the handheld display, so when the user looks through the display they see graphics overlaid on the real world How does ARToolkit work?

Limitations of ARToolkit – If users cover up part of the pattern with their hands or other objects the virtual object will disappear. – There are also range issues : Tracking range for different sized patterns – This range is also affected somewhat by pattern complexity – Tracking is also affected by the marker orientation relative to the camera – The tracking results are also affected by lighting conditions How does ARToolkit work?
