This application claims the priority of Taiwanese patent application No. 109127568, filed on Aug. 13, 2020, which is incorporated herewith by reference.
The present invention generally relates to a navigation system and method for controlling and integrating navigation routes, and more specifically to a navigation system and method employing a server, a network, at least one control unit, and at least one virtual navigation device in collocation with the schemes of virtual reality and augmented reality to combine and provide the aspects of exclusive navigation and free discovery for the user to experience and easily switch the accompanying navigation mode and the free discovery mode.
As the schemes of virtual reality and augmented reality have been constantly developed and made a great deal of progress, related fields of application and industries gradually expand. In addition to video game industry, such schemes have been also applied to other industries like movie, medication, and travel in need of navigation.
In the prior arts, the virtual reality navigation system usually provides home page or software program for the user to practically experience virtual navigation at the destination through controlling and operating a computer, mobile device, or head-mounted display. For example, virtual reality and augmented reality have been successfully employed in the process of real estate trade to help the buyer readily and remotely examine the status of the target real estate, or widely utilized in museum navigation to allow individual visitors in a museum to experience sense of presence and a realistic mood or atmosphere for the historical background.
In addition, the traditional virtual navigation system usually operates at a navigation mode or a free discovery mode. In the navigation mode, the image viewed by the user needs to dynamically change and update along the navigation route preset by the navigator, and at the same time, the user watches the image and hears the voice prepared by the navigator for introduction or explanation. In the free discovery mode, the user can change the view angle and position by inputting the appropriate control command or moving the navigation device.
However, the two modes of navigation in the prior arts have respective drawbacks. The drawback of the navigation mode is that the navigation route is fixed, and not allowed to switch or change according to individual preference during navigation. For the free discovery mode, while the view angle and position of the user and the navigation route can be updated as desired, the user fails to enjoy profound and exquisite description previously provided by the navigator.
Therefore, it is greatly needed to provide a new navigation system and method for controlling and integrating navigation routes, particularly employing the server, the network, the at least one control unit, and the at least one virtual navigation device in collocation with the schemes of virtual reality and augmented reality to allow the user to willingly and easily switch the accompanying navigation mode and the free discovery mode with the navigation routes, thereby overcoming the above problems in the prior arts.
The primary object of the present invention is to provide a navigation system for controlling and integrating navigation routes comprising a server, a network, at least one control unit, and at least one virtual navigation device for implementing a function of virtual reality navigation.

Further, the navigation mode comprises a virtual reality navigation mode and an augmented reality navigation mode, and the operation mode setting command is intended to select one of the virtual reality navigation mode and the augmented reality navigation mode. Specifically, the virtual navigation device displays the virtual reality image when the operation mode is the virtual reality navigation mode, and the virtual navigation device displays the augmented reality image when the operation mode is the augmented reality navigation mode.
In particular, when the user switches the free discovery mode to the navigation mode through the discovery mode switch command, the navigation route switch command provides the user to keep the current navigation route without change or switch the current navigation route to one of the other navigation routes for updating the current navigation route, or alternatively, the virtual navigation device determines to keep the current navigation route without change or switch the current navigation route to one of the other navigation routes for updating the current navigation route.
In addition, another object of the present invention is to provide a navigation method for controlling and integrating navigation routes comprising the steps S10, S20, S30, S40, S50, S60, S70, and S80 for implementing a function of virtual reality navigation for various navigation routes.
