Augmented reality is beginning to take hold.
Today’s invention is to use an application like this, running on eg an iPhone, to recognise eg a number of simple shapes in the real world which the user has specified (eg ‘+’ or ‘#’ etc, etc).
Each shape, once recognised, would trigger the software to paste in to the moving view of the current scene some graphic element.
A user could thus point the device at a list of names and have their faces displayed nearby.
This has already been done for words in complex scenes. Each word can now be replaced by a corresponding image pulled from eg Google image search.
