Abstract

A device for switching between code-based searching, optical character recognition (OCR) searching and visual searching is provided. The device includes a media content input for receiving media content from a camera or other element of the device and transferring this media content to a switch. Additionally, the device includes a meta-information input capable of receiving meta-information from an element of the device and transferring the meta-information to the switch. The switch is able to utilize the received media content and the meta-information to select and/or switch between a visual search algorithm, an OCR algorithm and a code-based algorithm.
