Abstract

A mobile computer may use building information to determine its indoor location or position. The mobile computer determines the dimensions of a room in a building using range determination or a range finder in the mobile computer. The determined dimensions of the room may be compared to the building information to locate, position, or track the mobile computer in the building.

Claims

1. A mobile computer characterized in that:

the mobile computer is configured to calculate at least two dimensions of a room in a building based on at least one range measurement;

a processor, of the mobile computer, is configured to compare the at least two dimensions of the room to room layout information of the building; and

the mobile computer is configured to determine, based on the comparison, a location of the room within the building where the mobile computer is located.

2. The mobile computer of claim 1, wherein the at least one range measurement of the room is based on any one of an ultrasound signal, light signal, a near visible light signal, or a laser signal transmitted or received by the mobile computer.

3. The mobile computer of claim 1, wherein the location of the room is used to determine a user context for an application on the mobile computer.

4. A method performed by a mobile computer, the method comprising:

calculating, by the mobile computer, at least two dimensions of a room in a building based on at least one range measurement;

comparing, by a processor of the mobile computer, the at least two dimensions of the room to room layout information of the building; and

determining, by the mobile computer based on the comparison, a location of the room within the building where the mobile computer is located.

5. The method of claim 4, wherein the at least one range measurement of the room is based on any one of an ultrasound signal, light signal, a near visible light signal, or a laser signal transmitted or received by the mobile computer.

6. The method of claim 4, wherein the location of the room is used to determine a user context for an application on the mobile computer.
