Technology giant Microsoft has sold more than 10 million Kinect sensor systems since it launched last November.
Guinness World Records says it is the fastest-selling consumer electronics device on record.
The sales figures far surpassed those of both the iPhone and iPad when launched by technology rival Apple.
Kinect is an infrared camera add-on for Microsoft's Xbox 360 games console that allows it to track body movements.
The success of Kinect has also helped to hike games sales.
The device sold at an average rate of 133,333 since its launch.
