Apple has won two patents from the US Patent & Trademark Office involving tags on mobile devices.
Patent number 20120062758 involves the relative positioning of devices based on captured images of tags and seems to involve the Places feature of iPhoto.
The patent is directed to determining the relative position of several devices by capturing representations of the device environments in which a tag is located. The devices can compare the captured representations to determine a perspective of the tag corresponding to each device. In some cases, a device can determine an absolute position relative to a coordinate system integrated in a tag. Using the positioning information, several devices can receive directions to come together at a particular meeting point. In some cases, several devices can operate an application that requires the interaction of several users of the devices (e.g., multi-player games).
The application can control the time or manner in which inputs are provided based on the relative positions of the devices. In some cases, the devices can display virtual content that is shared across several devices, where the different devices can each interact with the virtual content.
Patent number 20120064971 is for the dynamic display of virtual content on several devices using reference tags. This is directed to determining the relative position of several devices by capturing representations of the device environments in which a tag is located.
