This video show us a home with  some holographic built in. a view 3D with holographic make a real interface with computer. People can interact like a real device. A holographic view do not have a real shape, we can not touch it. We just can see, because it is a digital view representative by projector. But a digital view in 3D make people imagine that is a real thing they feel that thing have a real mass.

Holographic view is efficient solution with people which do not have a large room. They can observe thing like real thing without give a real room to placed that.

In this video we can see they do not need a real key to enter their home. When they in front of door, system will identify automatically there are person in front of door and view holographic keypad so person must enter the right key or password to open the door. If the password valid, system will open the door. In second scene, there are three mini tank on a  table. With holographic view, people can feel a real war sensation.  Tank can shool a virtual bomb to other tank and bomb viewed like real explosion.

Next scene show us animate in billiard, with holographic view billiard game can modify with some effect like thunder.  This is give a different sensation with game without animation. In billiard table, can added a water effect. Player will see table like a pool.

Keyboard in laptop, with hologram animation keyboard can viewed in a hologram. People easy to move it in the air. It is like portable keyboard without a real mass. Bring it to where ever you can, placed in any where. Hologram in television is like a 3D movie without tools like glasses when you see 3D movie in cinemas. In this video they can see a plane fly out of TV.

The weakness in this video are they do not see what  control all the hologram. They just viewed  something like projector which display all hologram.  This video just show one necessary thing  which we do in our home. That is key to open a door. Other scene just show game not necessary thing which we can do in our home with holographic view.

A hologram view like this can we see in iron man movie especially in ironman 2. In this movie we can see a real thing convert in to hologram than that hologram easy to manipulate like what we want. It is a simple thing when we use hologram, we do not need to manipulate or make a new shape of real thing. We just manipulate a hologram to see what we can do with the real device, so we do not afraid to make some mistake. It can be undo to previous state.

In future this hologram will be used in human life. People more interesting to 3D viewed. With hologram people can feel a real thing, observe it without give a large room to placed all things.

Hologram can be used in games, gamers will feel real sensation when graphic in 3D. Game with war scene will be more attractive. In education hologram can help people to observe something. Example in medical, a doctor trainee can feel a operation with hologram body. In this hologram a mistake can be tolerate, so doctor trainee can have more experience.

In home, hologram can be applied to open a door, to see refrigerator contain without open it,  make a small 3D cinema, leave a real video message, make a simulate lay out of room and etc.
