Bump - a natural interface with simple tools
Speaking about the natural user interface, people usually recall Kinect, augmented reality, tables with a built-in touch-interface and other sophisticated technological innovations. But if you approach the matter creatively, you can implement a completely natural interaction on the basis of quite ordinary iron. The Bump app for iOS and Android allows you to transfer contacts, photos and other information from one smartphone to another, just gently knocking them together. Where it is more natural! It does not need any Bluetooth, WiFi or NFC - pure “magic”.
The two main components are internet connection and geolocation. The impact is recorded by accelerometers of both smartphones. Bump servers using geolocation filter out a pair of strokes that correspond to each other in strength and direction, which occurred strictly simultaneously in close proximity to each other, after which the selected data is sent over the Internet from one phone to another. Everything.
The main idea - to use time synchronization by hitting two devices together - can be used not only for smartphones. Recently there was an opportunity to send photos to a desktop computer or laptop. To do this, go to the bu.mp site and hit the smartphone with the space bar. The principle of operation is the same. The location of the computer is determined through the browser geolocation API.

This method of identifying two neighboring devices does not seem very reliable, but the CEO and co-founder of the company, David Leeb, argues that the Bump algorithm almost always correctly find the right pair of devices from the first time. If there is the slightest doubt, users only need to repeat the blow to give the system additional information. Evidence of confidence Bump in its algorithm - the application Bump pay . It allows you to send each other payments up to $ 1000 via PayPal. So far it is available only for the iPhone and only in the USA.
