Ball having information display function

Abstract

The present invention relates to a ball having an information display function. The ball having an information display function according to the present invention includes a sensor unit which measures motion information of the ball which is moved by a force applied to the ball, a display unit which outputs the motion information outward from the ball, and a power supply unit which has a storage battery and supplies power to the sensor unit and the display unit.

1 . A ball with an information display function, which has an inner space and which is covered with a covering, comprising:
 a sensor unit for measuring motion information of the ball that moves by force applied to the ball;   a display unit for outputting the motion information to an outer surface of the ball; and   a power supply unit for supplying power to the sensor unit and the display unit,   wherein the sensor unit and the power supply unit are disposed at a center of the ball by being connected to elastic wire supports, and   wherein the display unit is disposed on an inner surface of the covering of the ball, and a part of the covering that covers the display unit is made of a transparent material.   
     
     
         2 . The ball of  claim 1 , further comprising a center-of-gravity control unit having a weight corresponding to that of the display unit, the center-of-gravity control unit being disposed at a location opposite the display unit. 
     
     
         3 . The ball of  claim 2 , wherein the center-of-gravity control unit includes a plurality of center-of-gravity control units, and the center-of-gravity control units are dispersively disposed on the inner surface of the covering of the ball so that a center of gravity of the ball is at the center of the ball. 
     
     
         4 . The ball of  claim 1 , wherein the sensor unit comprises:
 an acceleration sensor unit for measuring acceleration information generated as the ball moves; and   a location information sensor unit for measuring movement distance information of the ball by collecting GPS information.   
     
     
         5 . The ball of  claim 4 , wherein the acceleration sensor unit calculates speed information corresponding to one or more of an average speed and a maximum speed of the ball using the acceleration information and the movement distance information. 
     
     
         6 . The ball of  claim 5 , further comprising a lighting unit for outputting a different color of light depending on one or more of the acceleration information and the speed information. 
     
     
         7 . The ball of  claim 4 , wherein the sensor unit further comprises an energy measurement unit for calculating information of calories that a user consumes, using both information of a time, for which the ball moves, and previously input physical information. 
     
     
         8 . The ball of  claim 4 , wherein the sensor unit further comprises an impact sensor unit for calculating impulse information applied to the ball using the acceleration information. 
     
     
         9 . The ball of  claim 8 , further comprising a lighting unit for outputting a different color of light depending on the impulse information. 
     
     
         10 . The ball of  claim 1 , wherein the display unit is made of a flexible display material. 
     
     
         11 . The ball of  claim 10 , wherein between the display unit and the covering of the ball, a display protection unit made of a transparent material is deposited. 
     
     
         12 . The ball of  claim 1 , wherein the power supply unit comprises a solar cell for collecting solar energy and for converting the collected solar energy into electric energy, the solar cell being disposed on the inner surface of the covering of the ball and a part of the covering that covers the solar cell being made of a transparent material. 
     
     
         13 . The ball of  claim 1 , further comprising a communication unit for transmitting the motion information of the ball to an external terminal. 
     
     
         14 . The ball of  claim 13 , wherein the communication unit controls an on/off operation of the power supply unit in compliance with operation control information by receiving the operation control information from the external terminal.
