Meet Pinch: the Interface that Links Displays from Multiple Devices

by: - Last updated on: November 5th, 2012

Linking displays to one another is not a new concept. Attaching several displays to one another for rendering important invents like football matches has been seen in the television since its very start, and for strong reasons too. It is fairly cheaper to use and also to transport nine monitors while displaying a big image, than a huge panel which might break or malfunction at any time. And this is the same concept that the Pinch interface wishes to introduce, albeit for smartphones.

Although it’s highly unlikely to see football matches on three iPhones linked to one another, there are high chances that someone would really use a tablet linked to a smartphone at his workplace or say, for gaming.

How exactly the Pinch interface works?

Well, Pinch was developed more out of curiosity and ingenuity by a research group at the Tokyo University of Technology, to help developers construct applications that can be shared between several screens and that can work with a symbiosis of smart mobiles. In a few words, the Pinch interface connects one smartphone to another by simply aligning the two and pinching the screen.


When the user places and index finger on a device, the thumb on the other and then draws them together, the two products will be linked by Pinch and they will act as an single panel. As developers put, there could be an extended market for this future application, one which includes the following uses:

  • Advertising – mainly for presentation uses, where people could place two devices next to each other while discussing about products
  • Applications – although people usually own just a smartphone, there are enough cases when two phones could be used to play a great game or enhance productivity
  • Music listening
  • Watching movies

For the record, this project has only been revealed to developers with the purpose of creating a new kind of applications and to invoke imagination, overall.
