Visual Searching

Visual Searching is an automatic object identification method whereby the source device uses a camera or sometimes two cameras for depth perception, to scan a physical location to find a particular object or particular feature at that location.

Conceivably it could also be used just as efficiently in a virtual environment. However there are typically more efficient ways of locating an object in a virtual space than are available in a physical one.

Visual Searching relies on some of the same core technologies that augmented reality does. It uses machine vision, run from a neural network so it can detect approximate matches rather than just being limited to perfect fits. Quite often something that bears a resemblance to an internal 3D virtual environment is constructed, so as to work out what objects would look like from different angles to determine if an object actually matches. Results are usually returned that overcome a probability threshold, similar to the way human vision operates.

Unlike AR, Visual Searching is usually not a real-time. When a search is requested, a search is performed, and may take several seconds depending on the available computing power.

Resource List: Visual AR Development
Visual augmented reality elements are amongst the simplest AR elements to integrate into the physical environment. That said, tracking and adjusting for a continually changing user viewpoint, without it becoming obvious that the data is superimposed from VR, is a major undertaking.

Cystal [eye]ball: Precognitive Eyes are Normal
It takes our brain nearly one-tenth of a second to translate the light that hits our retina into a visual perception of the world around us. Because of the 10th of a second delay, an Assistant Professor has developed a case arguing that our visual system needs to do more than just report current events - it needs to see the future as well.
