Definitions

• VR Virtual Reality
• Sensing technologies include mechanical, electric field, optical, inertial, acoustic and magneto static. Many of these technologies have been adapted to measure the location of body parts in 3D. Certain limitations are still stand behind the versatility usage of these conventional devices. From this point, we think to use different technology to record 3D image in one step and then to retrieve it in another step depending on holography with electromagnetic waves in microwave region.
• microwave holography the holographic data is not recorded in a holograph plate, as in laser case, but it is recorded in an electronic memory.
• This allows a lot of applications to be created as radar inverse scattering and contour mapping.
• a wide area of attention is realizing the computer 3D image and its vast fields of applications, which is one of the dreams of present image processing technology.
• we present in this invention an application on microwave holography using microstrip antennas, which is a 3DMI- HOPE input device.
• it is useful in generating a body fitted grid system in 3D space.
• Input devices such as the mouse, trackball and graphics tablet are often used for pointing and selection in conjunction with the present generation of 2D user interface.
