Abstract

A mobile computer may determine it is located in a vehicle or a conveyance based on a measured distance, satellite related positioning information, and a touch input.

First claim

What is claimed is:

1. A mobile device for tracking a location of the mobile device, the mobile device comprising:
at least one sensor configured to measure a doppler shift of a received signal; and
at least one processor configured to determine a distance between the mobile device and a conveyance based on the doppler shift, and identify whether the mobile device is in the conveyance based on the distance.

2. The mobile device of claim 1 , wherein the at least one sensor is further configured to:
transmit a Wi-Fi signal; and
receive a reflected signal of the transmitted Wi-Fi signal as the received signal.

3. A method for tracking a location of a mobile device, the method comprising:
measuring a doppler shift of a received signal; and
determining a distance between the mobile device and a conveyance based on the doppler shift, and identifying whether the mobile device is in the conveyance based on the distance.

4. The method of claim 3 , further comprising:
transmitting a Wi-Fi signal; and
receiving a reflected signal of the transmitted Wi-Fi signal as the received signal.

5. The mobile device of claim 1 , wherein the at least one processor is further configured to:
control a transceiver to transmit a signal,
determine the distance based on the signal and the doppler shift,
compare the distance with at least one of a width and length of the conveyance, and
identify whether the mobile device is in the conveyance based on a result of the comparing.

6. The mobile device of claim 5 , wherein the width and length of the conveyance is retrieved from the mobile device.

7. The mobile device of claim 5 , wherein the width and length of the conveyance is obtained by communicating over a network proving a position.

8. The mobile device of claim 5 , wherein the at least one processor is further configured to change a type of the signal according to a radio or acoustic characteristics of at least one room included in a nearby building.

9. The mobile device of claim 5 , wherein the signal is at least one of a Wi-Fi signal, an ultra sound signal, an ultrasonic signal, a non-audible signal to humans sound, a near visible light signal, an infrared signal, a blue tooth signal, a radio frequency signal, or a low frequency signal.

10. The method of claim 3 , wherein the determining of the distance comprises:
transmitting a signal;
determining the distance based on the signal and the doppler shift;
comparing the distance with at least one of a width and length of the conveyance; and
identifying whether the mobile device is in the conveyance based on a result of the comparing.

11. The method of claim 10 , wherein the width and length of the conveyance is retrieved from the mobile device.

12. The method of claim 10 , wherein the width and length of the conveyance is obtained by communicating over a network proving a position.

13. The method of claim 3 , wherein a type of the signal is changed according to a radio or acoustic characteristics of at least one room included in a nearby building.

14. The method of claim 3 , wherein the signal is at least one of a Wi-Fi signal, an ultra sound signal, an ultrasonic signal, a non-audible signal to humans sound, a near visible light signal, an infrared signal, a blue tooth signal, a radio frequency signal, or a low frequency signal.
