File transfers between PC and phones via video

Transferring files from your computer to your smart phone may soon no longer need tedious cable or Wi-Fi setup and configuration.  If Fujitsu Laboratories Ltd.’s work on the matter pans out, all users would need is a steady hand and some basic video-shooting skills to move documents, slides presentations and photographs from their computers to their smart phones.

Fujitsu today announced the development of the technology which essentially makes it possible for people to transfer files from their PCs to a mobile phone of tablet by simply using their mobile device to capture a video of the file displayed on their computer screen. Fujitsu hopes to demonstrate the technology at the Mobile World Congress in Barcelona in February.

The file transfer is made possible by “superimposing IP addresses and other device-specific information that is invisible to the human eye onto the PC screen in real-time,” according to Fujitsu. “The technology can identify the target PC when the user takes a video of the screen with a mobile camera.”

A communication pat between the target PC and the mobile device is then established and transfer of the file displayed on the computer screen takes place.

The method requires software to be loaded onto the target PC but Fujitsu says this beats having users to go through the process using USB cables, or a Wi-Fi connection, or use cloud-based file sharing services like Dropbox.

Other methods that use image detection technology to analyze images of a PC screen captured by a mobile phone camera already exist. However, Fujitsu said, these methods do not use unique identifier information such as the PC’s IP address so these methods still require users to prepare their PC and mobile phones to communicate with each other.
