Are you sick of strangers reading your messages over your shoulder when you're on the train or the bus?
In an era when everybody is carrying around smartphones and tablets everywhere they go, it is increasingly difficult to keep private things private.
Now a Turkish technology whizz has come up with a way to hide smartphone screens from prying eyes, using a special kind of display that can only be seen wearing special "smart" glasses.
Celal Göger, a 40-year-old phone store manager from Diyarbakir, Turkey, came up with the concept while roaming around on crowded communal transport in Istanbul.
He became annoyed when he realised that other commuters were gazing over his shoulder at business texts on his phone.
"Someone's phone is a very personal item and I think it's extremely disrespectful when other people stare at it," he said.
Göger, who was born in a small village with no lights, headed straight to the small workshop behind his store to formulate a way of hiding his screen from others.
It took him 4 months to come up with the ingenious "ghost phone"' which he is planning to call C.COGER I.
The phone comprises of a chip that makes the screen look white to anybody who looks at it with the naked eye. Though, a second chip in the glasses pairs to the phone, making it detectible to the wearer.
"When I finished my invention I started telling people about it but nobody believed me," said Göger.
"They thought it must be some kind of magic trick until they saw my invention which left them absolutely gobsmacked!"
No other details have been released about exactly how the device works, or when it will be available. However, Göger is looking for funding to take his project to the next level.
"I think I was born in the wrong place at the wrong time," he said.
"If I had been born in the UK, I think I would have gotten a lot more support to move this project forward and start mass production of my invention.
"If I can get funding I am planning to take this project further and install an on/off button on the phone which means that the user decides whether to activate the function or not."
