Building directory aided navigation
First Claim
1. A method of interacting with a building directory using a mobile device, the method comprising:
- receiving a captured image of the building directory including a plurality of location values;
executing an image recognition algorithm on the captured image of the building directory;
identifying at least one location value based on an output of the image recognition algorithm; and
accessing a map database according to the at least one location value.

Abstract
A navigation system utilizes building directories to aid navigation. A mobile device, such as a mobile phone, captures an image of a building directory. The building directory includes information regarding the names and/or locations of tenants. An image recognition algorithm is performed on the captured image to extract information from the building directory. The extracted information is used to access a map database. The mobile device may display directions or a map to guide the user to a selected destination. In addition, the captured image may be used to build the map database or update the map database. Finally, the captured image may be matched with stored images of the building directory to determine the current location of the mobile device.

21. A non-transitory computer readable medium configured to store instructions for a method navigation using a building directory, the method comprising:
-
capturing an image of the building directory including a plurality of location values; sending the image of the building directory to a map developer for matching with a map database using an image recognition algorithm; receiving data from the map developer, wherein the data is associated with at least one of the plurality of location values; and displaying information to a user based on the data.
