Abstract:
A method and a processing device may provide navigational information including non-photographic cues, such as, contextual color, texture, and structure cues, corresponding to physical entities visible to a party traveling along a determined route. In one embodiment, the non-photographic cues may be previously stored in a database. In another embodiment, non-photographic cues may be extracted from at least one provided image of a geographic area. In a third embodiment, a sequence of non-photographic cues may be automatically extracted from at least one image of a geographic area and, if the sequence of non-photographic cues was not previously saved, the sequence of non-photographic cues may be saved, along with related information, for later use when the sequence of non-photographic cues corresponds to a desired location. The provided navigational information may be presented in a number of ways including a simplified map, textual instructions, or generated speech.
