Abstract: An improved method for verifying whether a character-recognition technology has correctly identified which characters are represented by character images involves displaying the uncertain character images in place of their respective hypothesis characters in a document being read a verifier. The verifier may mark incorrectly spelled words containing the uncertain character images. Based on the markings, a system adjusts a confidence level associated with the hypothesis about the uncertain character in order to obtain a confirmed hypothesis linked to the uncertain character.

Abstract: Systems and methods for processing multi-touch input to select a displayed option. An example method may comprise: presenting, on a display of a computing device, a plurality of alternative options pertaining to digital content; receiving, via a touch-sensitive input area of the display, a multi-touch gesture comprising one or more touch contacts with the touch-sensitive input area; and identifying an option having an ordinal position on the display, relative to positions of other alternative options, that corresponds to a number of touch contacts comprised by the received multi-touch gesture.
