An iPhone 5 concept-video by designer Kris Groen shows a device with a 4-inch display in which the home button has been replaced by two separate home bumpers on the side.
The idea behind the concept is that with the future iPhone the user can simply squeeze the size of the phone on the left or right side of the device to use the home button.
The squeezing comes naturally since the position of the side buttons is based on the way phones are held.
By squeezing the buttons there a number of functions that the smartphone can perform, with no need to touch the screen.
Groen has designed the iPhone with a 4-inch Retina display.
Watch the video below to see a demonstration of the concept.
