what is pinch to zoom patent from apple? Patent #7,812,826 was first applied for on December 29, 2006, and over the course of the patent process the claims have been significantly narrowed to cover a very specific set of actions:
1. *A multitouch display detects at least two contacts.* 2. *Those contacts perform a first gesture.* 3. *That gesture adjusts an image in some way: magnification, orientation and rotation are specifically claimed, but the patent is broad enough to cover virtually any adjustment.* 4. *The first set of contacts is broken.* 5. *A second set of contacts is detected.* 6. *The second contacts perform another gesture within a pre-determined period of time.* 7. *The gesture continues to adjust the image in the same way.* It's steps 5, 6, and 7 that are critically important here: Apple doesn't have a patent on "pinch-to-zoom" generally, but rather pinching to zoom, and then pinching to zoom again within some fixed period of time. How long that period lasts is totally up in the air, but it has to be defined somewhere -- this patent doesn't really apply unless there's a clock running and a second gesture takes place. Still, it's the first granted patent on the now-ubiquitous gesture we've seen, and based on its filing history it's essentially effective as of December 30, 2005 -- long before anything multitouch products with pinch to zoom had arrived on the market. That's no small weapon to bear -- we'll see what Apple does with it. http://www.engadget.com/2010/10/13/apple-awarded-limited-patent-on-pinch-to-zoom/ best regards, sony djuana -- "Indonesian Android Community" Join: http://forum.android.or.id =============== Download Aplikasi Kompas versi Digital dan Keren https://play.google.com/store/apps/details?id=com.kompas.android.kec -------------------------- Download Aplikasi AR "MONSTAR" dari Indosat https://play.google.com/store/apps/details?id=com.ar.monstarunity --------------------- Sale Gadget Android paling heboh hanya di Multiply!
