Catch the screen

Abstract

The invention relates to a method and an system for displaying viewscreen information on a display in a mobile communication device, wherein the viewscreen information is related to information shown on a viewscreen, wherein the method comprise the steps of determining a direction to the viewscreen from the mobile communication device, communicating the determined direction to a server, determining, in the server, viewscreen information based on the direction to the viewscreen, wherein the viewscreen information is related to information displayed on the viewscreen, receiving viewscreen information from the server in the mobile communication device and displaying the viewscreen information on the display in the mobile communication device.

What is claimed is: 
     
         1 . A method, performed in a mobile communication device comprising a display, for displaying viewscreen information on said display, the method comprising:
 determining a direction to said viewscreen from said mobile communication device by determining an orientation of the mobile communication device;   communicating said direction and a time when the direction from said mobile communication device to said viewscreen was determined to a server;   receiving said viewscreen information based on said direction and time in said mobile communication device from said server, wherein the viewscreen information is based on said direction and said time and includes information that was displayed on said viewscreen at said time or is displayed on said viewscreen; and   displaying said viewscreen information on said display in said mobile communication device.   
     
     
         2 . The method according to  claim 1 , further comprising:
 determining a geographical position of said mobile communication device; and   communicating said geographical position to said server, wherein said viewscreen information is further based on said geographical position.   
     
     
         3 . The method according to  claim 1 , further comprising:
 capturing an image of at least a part of said viewscreen using an image recording device in said mobile communication device;   deriving image information from said captured image; and   communicating said image information to said server, wherein said viewscreen information is further based on said image information.   
     
     
         4 . The method according to  claim 1 , wherein said determining of said direction to said viewscreen comprises:
 capturing an image of at least a part of said viewscreen using an image recording device in said mobile communication device;   deriving image information from said captured image;   identifying graphical features from said image information; and   determining said direction to said viewscreen based on said graphical features.   
     
     
         5 . The method according to  claim 2 , wherein said geographical position of said mobile communication device is determined based on said graphical features. 
     
     
         6 . The method according to  claim 2 , wherein the determining of the geographical position of said mobile communication device further comprises:
 determining current elevation of said mobile communication device using a pressure sensor; and   communicating said current elevation of said mobile communication device to said server, wherein said viewscreen information is further based on said current elevation of said mobile communication device.   
     
     
         7 . The method according to  claim 1 , wherein said determining of direction to said viewscreen from said mobile communication device is based on compass information or compass and accelerometer information of said mobile communication device. 
     
     
         8 . The method according to  claim 2 , wherein said determining of geographical position of said mobile communication device is based on one of or a combination of: Global Positioning System information, Inertial Navigation System information, and Network-based localization information. 
     
     
         9 . A system for displaying viewscreen information on a display in a mobile communication device, wherein the system comprises:
 a direction determining unit in said mobile communication device adapted to determine a direction to said viewscreen from said mobile communication device by determining an orientation of the mobile communication device;   a communication unit in said mobile communication device adapted to transmit the direction and a time when the direction from said mobile communication device to said viewscreen was determined to a server;   a receiving unit in said mobile communication device adapted to receive, from said server, viewscreen information based on said direction and said time, wherein the viewscreen information is based on said direction and said time and comprises information that was displayed on said viewscreen at said time or is displayed on said viewscreen; and   a display adapted to display said viewscreen information on said display in said mobile communication device.   
     
     
         10 . The system according to  claim 9 , further comprising:
 a position determining unit adapted to determine a geographical position of said mobile communication device, wherein said communication unit is further adapted to transmit said geographical position to said server, wherein said viewscreen information is further based on said geographical position.   
     
     
         11 . The system according to  claim 9 , further comprising:
 an image capturing unit in said mobile communication device adapted to capture an image of at least a part of said viewscreen; and   an image processor adapted to derive image information from said captured image,   wherein said communication unit is further adapted to transmit said image information to said server, and   wherein said viewscreen information is further based on said image information.   
     
     
         12 . The system according to  claim 9 , further comprising:
 an image capturing unit in said mobile communication device adapted to capture an image of at least a part of said viewscreen; and   an image processor adapted to derive image information from said captured image, wherein the image processor is further adapted to identify graphical features from said image information;   wherein said direction determining unit further bases the determining of the direction to said viewscreen from said mobile communication device on said graphical features.   
     
     
         13 . The system according to  claim 10 , further comprising:
 a pressure determining unit adapted to determine the current elevation of said mobile communication unit based on measuring an ambient pressure of said mobile communication unit,   wherein said communication unit is further adapted to transmit said current elevation to said server, and   wherein said viewscreen information is further based on said current elevation.   
     
     
         14 . The system according to  claim 9 , wherein said direction determining unit in said mobile communication device determines the direction to said viewscreen from said mobile communication device based on either compass information from a compass unit in said mobile communication unit or compass information from a compass unit and acceleration information from an acceleration unit in said mobile communication unit. 
     
     
         15 . The system according to  claim 10 , wherein said position determining unit in said mobile communication device determines the geographical position of said mobile communication device based on one of or a combination of: Global Positioning System information, Inertial Navigation System information, and network-based localization information.
