  • Publication number: 20150168167
    Abstract: A system and a method of providing weather information to a driver of a vehicle along a desired route are provided. The method includes setting, by a controller, the desired route from a current position of a vehicle to a destination and transmitting information regarding the desired route to a telematics server. In addition, the controller is configured to receive current weather information that corresponds to the desired route from the telematics server and map the current weather information with map data to display the mapped current weather information on a user interface.

  • Patent number: 7468742
    Abstract: The present invention discloses an interactive presentation system which allows a presenter to perform a presentation while having various interactions directly with presentation material images in real time through a gesture or/and voice. The interactive presentation system comprises: an active infrared camera; a command recognition system connected to the active infrared camera; and an image synthesis system connected to the active infrared camera and the command recognition system. The presentation system may further comprises a stereo camera set for properly synthesizing a presenter in a 3D image and a 3D motion system. By this configuration, it is possible to embody an interactive presentation system in which a command through a presenter's gesture or voice is processed in real time and the image of the presenter is synthesized in a presentation material screen in real time, and accordingly the audiovisual effect is maximized.
