A three-dimensional interactive simulated-globe system application in education

This study proposes an innovative three-dimensional (3D) Interactive Simulated-Globe System application. The instrument includes: a data processing unit, a wireless control unit, an image capturing unit, a laser emission unit as well as 3D hemispheric body imaging. The 3D hemispheric body imaging is designed to display the output image from a data processing unit. The Laser emission unit is for emitting a laser spot on the output image. Based on the spherical coordinates of the laser spot, detected by a data processing unit through an image capture unit, the spherical coordinates, with a plane coordinates converter operation, can provide spherical coordinates to convert into plane coordinates for the data processing unit. Utilizing the coordinates location, of the laser spot through image acquisition, calibration and internal coordinates with external coordinate converter operation can be guided the cursor, output by the data processing unit on 3D hemispheric body to launch synchronous movement with laser spot. To combine wireless control technology can perform synchronous driven, control and interactive with the software image on 3D hemispheric body. This work allows general planet software such as Google Earth (Mar, Moon), used in a variety of panel displays or projection turn into the 3D hemispheric body, and then through the laser spot emitted by the laser emission unit and wireless control unit, allows the laser spot in synchronization to control the cursor and software on the 3D hemispheric body imaging for a variety of interactive, and then perform the effect of 3D interactive globe system in any classroom or astronomical Museum for formal and Social education.
