Abstract

Methods and devices provide a gesture activated file sharing functionality enabling users to share files with other nearby computing devices. The file sharing functionality may include establishing wireless links with nearby devices and determine their relative locations. The computing device may detect a file sharing gesture and transmit files to or request files from a nearby device in response to the gesture. Base on gesture parameters, e.g., direction, speed and shape, and computing device attitude parameters, e.g., tilt angle and pointing direction, the computing device may identify a targeted device to which a file may be transmitted. The computing device may request user verification of the identified device and send a request to transmit files to the targeted device. The computing devices may transmit files using networks and addresses provided over the device-to-device communication links.
