Google Goggles allows you to search using pictures.
The concept is still in it’s infancy so it won’t work so well on less readily identifiable objects, but the potential ignites the imagination.
It has some pretty clear educational benefits for sure, like researching objects and places of historical, cultural or geographical interest. Could it eventually be used to provide guidance for solving every day challenges, such as diagnosing technical or engineering (or God forbid, medical!) issues simply by taking a photograph of the problem?
What impact will this technology have for marketers? It could help consumers access product information in stores (like code scanners), or allow them to identify the vendors of products they see and like? In any event it will increase the importance of image usage in the search optimization process. Time for a new product shoot methinks.
