Mobile Phone Allows Boss to Snoop
KDDI Corp. has developed mobile phone technology that detects even the tiniest actions of the user by analyzing the movement of accelerometers embedded in the devices. Previous mobile phone sensors could only detect repetitive movements, but KDDI researchers say the new technology can identify activities such as walking, climbing stairs, and cleaning.
"Technically, I think this is an incredibly important innovation," says International University of Japan's Philip Sugai. The KDDI system can detect more complex behavior by using analytical software to match patterns of common movements. The researchers say the system is designed to enable employees to work more efficiently and managers to evaluate employees' performance.
"It's part of our research into a total ubiquitous technological society, and activity recognition is an important part of that," says KDDI's Hiroyuki Yokoyama.
