Casio Develops Technology to Send Data Visually Between Devices
20.05.12
Casio has developed a new way to send information between smartphones and other gadgets, encoding it visually in small sets of flashing pixels that appear on the screen of one device and are read by the camera of another.
The company, known for its G-Shock watches, digital cameras and rugged mobile phones, is set to reveal the technology at the Consumer Electronics Show in Las Vegas next week. IDG News Service was given a sneak peak at Casio's headquarters in Tokyo.
The technology was simple to use on a demo app created for iOS devices. One user selects the data to be sent -- contact information, an image or a message -- and their device's screen is filled with a circle that repeatedly flashes a series of colors. The user receiving the information points their camera at the circle, and after a few seconds the colors are decoded and the data received.
When both parties have the software installed, it allows them to share information without the clunky process of exchanging email addresses or phone numbers, or setting up a Bluetooth connection. And a person receiving the data can point their camera at 10 to 15 devices at once, allowing them to acquire contact information from a whole group of people at the same time, for example.
