When you have a phone screen, you can use an outdoor projector to watch TV, say scientists
Scientists at the University of Nottingham have discovered that a smartphone can make a computer screen appear as an outdoor viewing platform, making the device seem to be floating in the air.
Their findings appear in Nature Communications, a journal published by the National Science Foundation.
“We have used an app to create a simple motion simulator,” said lead author Dr Nimesh Panchal, from the Centre for Intelligent Systems at the university.
“The simulation was simple and easy to use, and we were able to see how it would look like in real-life situations.”
The smartphone’s screen is an ideal device for displaying pictures of the environment that the user might want to see, for example, in the living room.
“They are also able to simulate a 3D model of the real world by showing a picture of the screen, the researchers said.”
Our work is important as it gives us a tool to demonstrate how to make the illusion of a 3-D image in real time by using simple, but efficient methods.””
It may have many uses in the future for augmented reality, or in other applications.”

“The scientists are using the app called Projector 2 to make a simple 3D picture appear on the screen.
They then put the picture in front of a computer, and used an external projector to simulate the effect of the phone screen on the computer screen.”
When you turn it on, the device appears to be a floating object floating in space.””
When the phone is turned off, the picture becomes a floating screen in the sky.”
When you turn it on, the device appears to be a floating object floating in space.
“In this way, we can simulate the illusion that the screen is floating on the ground.”
“It may be useful in other settings, for instance in virtual reality games or interactive environments,” he added.
The app works by creating a 3DS Max image of the device and projecting it on the wall.
When the user turns the device on, they will see the picture as it would appear on a real TV screen.
In some conditions, such as when the screen becomes dim, the illusion can be very strong.
“We can create an illusion of the illusion by making the phone appear to be hovering over the screen,” Dr Gildest said.
The smartphone app works in the same way as the iPhone or the Samsung Galaxy, which also simulate the appearance of a real 3D display.
“You can turn off the screen to make it appear dim and then turn the device back on to see the effect.
The effect is not quite as subtle as it looks on the iPhone, but it is very close,” Dr Dhingra said.
In addition to the practical applications, the research has applications in the sciences, as well.
“These techniques could be applied to simulate 3D holograms, for which there is still no practical way to simulate real 3-d objects,” Professor Gilders said.
