Turkey: Have you ever felt exasperated by strangers peeping into your phone over your shoulder when you're on the train or bus? It becomes very difficult to keep things private nowadays where everyone carries smartphones and tablets to communicate.
However, a Turkish man has come up with just the right invention that allows users to hide smartphone screens from prying eyes using a special 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 idea while travelling around on crowded public transport in Istanbul.
As he got annoyed when he realised that other passengers were peering over his shoulder at some of his business messages 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 electricity, headed straight to the small workshop behind his store to invent a way of hiding his screen from other people.
It took him four months to come up with the ingenious "ghost phone"' which he is planning to call C.COGER I.
The phone contains a chip that makes the screen appear white to anyone who looks at it from the side or with the naked eye. However, a second chip in the glasses connects to the phone, making it visible only to the person wearing those glasses.
"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 as to how exactly the device works, or when would it be available. However, Göger is looking for investors 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."
