In the coming weeks I will examine a few technologies that could function like a holodeck. Today I’ll talk about the holographic TV [hTV] a technology which is just around the corner.
A true hTV differs from a 3D TV by making the objects appear in the room instead of merely creating an illusion that they are 3D. When viewing a 3D TV everybody watches the same picture no matter where you are in relation to the screen. A hTV sends out the light in such a way that an object will actually appear to be in the room. your relation to the TV will therefore actually determine what you view. You can compare the difference between viewing a scene in a show box and having a model of the same scene. In the show box you see a scene from a fixed perspective while you can walk around a model.
A hTV has the benefit of not being harmful to the eyes and eye development in children and will not cause headaches and exhaustion associated with traditional 3D TV’s. This is because a hTV actually projects the object into the room so your eyes can focus on an “object” instead of the screen.
Restrictions with native hTV content have to do with the available processing power and bandwidth. You can imagine that in order to display an object in 3D from any given angle requires a massive amount of data. This will mean that in the first generations of the hTV it will track your eye movements and only display the viewing angle you see. This means that the number of viewers is automatically limited to the number of people the hTV can track and display an object for. As the cost of bandwidth and processing power decreases more angles will be added.
Early adopters of the hTV will be of course the military gaining an advantage when they are able to plan missions on a live 3D map. I also see potential for industrial designers and architects allowing clients to view their work without having to produce a physical model. This means they can adapt their work to the clients wish live with the click of a button. Of course the advertisement industry will use the technology to attract attention to their products. Later on theme parks and cinema will install hTV technology to entertain their costumers.
The first hTV native consumer applications will probably come from the gaming industry. Which just eliminates the step which makes their 3D games able to display on a 2D screen. Sports will benefit from hTV technology allowing you to view the pitch from any angle you desire and allowing you to walk around so you can see what the players see. The other early adopters for consumers will be the porn industry which, unlike Hollywood, does not care about artistic value of their production as long as it gets the job done.
Hollywood will need more time however so they can figure out how to get the story across when people can view it from unintended angles. Maybe they will keep to showing their films more like the traditional 3D technology. Where there is just one viewpoint for all viewers, independent of the location of the viewer like a show box having layers of 2D images projected a little bit apart from each other creating the illusion of 3D.
the technology to shoot a film in native hTV is already available to consumers. A hacked xbox kinect camera has been shown to film a room 180 degrees in 3D. two or three of these camera’s could capture (nearly) an entire room allowing you to view an action in that room from any angle.
