Open the CIPO recordAbstract From the Canadian patent
In a virtual set a computer generated virtual image is combined with a real set. Registration data defines a transformation allowing virtual image data to be combined with image data derived from a real set. A reference plane is identified (902) in the real set which is associated (903) to a plane defined in the virtual world space. Differences in positions between the real and virtual planes are determined (904) to produce registration data.

Why it's free to use
- Filed February 16, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 16, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 16, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
