Benefits of technology

The present invention provides an apparatus and method for automatically switching between a vehicle navigation mode and a personal navigation mode in a navigation device supporting both modes without user manipulation. The device determines whether the user is using a vehicle or walking and switches accordingly. This allows for seamless navigation experience and improves user experience.

Problems solved by technology

The use of separate navigation devices for car navigation and personal navigation increases cost and causes inconvenience.
As a result, conventional navigation devices cause inconvenience because the user has to separately input car navigation information and personal navigation information.
Moreover, when the user mistakenly switches to car navigation for personal navigation or vice versa, it may result in wrong route guiding.

first embodiment

[0037] According to the present invention, the navigation device performs mode switching between the car navigation mode and the personal navigation mode according to whether the navigation device is mounted in the navigation device holder 110.

[0038]FIG. 2 is a flowchart illustrating mode switching between the car navigation mode and the personal navigation mode according to the first embodiment of the present invention. Referring to FIG. 2, the navigation device executes a navigation program in response to a navigation program execution request from a user in step 202. Upon execution of the navigation program, the navigation device determines whether it is mounted in the navigation device holder 110 in step 204. The navigation device can make a determination using a mechanical method and a message transmission method.

[0039] According to the mechanical method, the navigation device determines whether it is mounted in the navigation device holder 110 by checking if a button in a por...

second embodiment

[0043] According to the present invention, the navigation device performs mode switching between the car navigation mode and the personal navigation mode according to whether a GPS speed provided by the GPS receiver 102 is higher than a predetermined speed.

[0044]FIG. 3 is a flowchart illustrating mode switching between the car navigation mode and the personal navigation mode according to the second embodiment of the present invention. Referring to FIG. 3, the navigation device executes a navigation program in response to a navigation program execution request from the user in step 402. Upon execution of the navigation program, the navigation device acquires GPS speed information from the GPS receiver 102 in step 404.

[0045] The navigation device then determines whether the acquired GPS speed is high in step 406. In other words, the navigation device determines whether the acquired GPS speed is higher than a predetermined speed threshold. The GPS speed has a limit in the personal nav...

third embodiment

[0047] According to the present invention, the navigation device performs mode switching between the car navigation mode and the personal navigation mode according to whether a step is detected using an output of the accelerometer 104.

[0048]FIG. 4 is a flowchart illustrating mode switching between the car navigation mode and the personal navigation mode according to the third embodiment of the present invention. Referring to FIG. 4, the navigation device executes a navigation program in response to a navigation program execution request from the user in step 502. The navigation device acquires an acceleration measured by the accelerometer 104 in step 504.

[0049] The navigation device recognizes a step pattern using the measured acceleration in step 506. When a user walks, an acceleration measured by the accelerometer 104 is output as a frequency waveform of a predetermined pattern in which an acceleration component toward the center of the earth, i.e., an acceleration magnitude towa...

Abstract

Provided is an apparatus and method for switching a navigation mode between a vehicle navigation mode and a personal navigation mode in a navigation device supporting vehicle navigation and personal navigation. Switching between the vehicle navigation mode and the personal navigation mode is performed according to whether the navigation device is mounted in a navigation device holder, whether a GPS speed provided by a GPS receiver is higher than a predetermined speed, and whether a step is detected using an output of an accelerometer. Since mode switching between the vehicle navigation mode and the personal navigation mode is automatically performed, a user does not need to manually perform mode switching.

Description

PRIORITY [0001] This application claims priority under 35 U.S.C. §119 to an application entitled “Apparatus and Method for Switching Navigation Mode between Car Navigation Mode and Personal Navigation Mode in Navigation Device” filed in the Korean Intellectual Property Office on May 19, 2005 and assigned Serial No. 2005-42075, the entire contents of which are hereby incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates generally to a navigation system supporting vehicle navigation and personal navigation, and in particular, to an apparatus and method for switching a navigation mode between a vehicle navigation mode and a personal navigation mode in a navigation device supporting vehicle navigation and personal navigation. [0004] 2. Description of the Related Art [0005] Vehicle navigation systems, for example a car navigation system, recognizes a current position of a user's car. It provides an optimal rout...
