The Kinect, a motion-sensing input device made by Microsoft and designed as a video game controller, was first introduced in November 2010, and was upgraded for the 2013 release of the eighth-generation Xbox One video game console. Kinect's capabilities were revealed in May 2013. The new Kinect uses an ultra-wide 1080p camera, which can function in the dark due to an infrared sensor. It employs higher-end processing power and new software, can distinguish between fine movements (such as a thumb movements), and can determine a user's heart rate by looking at his/her face. Microsoft filed a patent application in 2011 that suggests that the corporation may use the Kinect camera system to monitor the behavior of television viewers as part of a plan to make the viewing experience more interactive. On July 19, 2013, Microsoft stocks suffered its biggest one-day percentage sell-off since the year 2000 after its fourth-quarter report raised concerns among the investors on the poor showings of both Windows 8 and the Surface tablet; with more than 11 percentage points declining Microsoft suffered a loss of more than US$32 billion. For the 2010 fiscal year, Microsoft had five product divisions: Windows Division, Server and Tools, Online Services Division, Microsoft Business Division and Entertainment and Devices Division.
