RIM applies for patent on detecting emotion in messaging, wants you chilled while you BBM

Ever get the shakes sending out an angry text message? You'd better be careful if you buy a BlackBerry in the future, as RIM is trying for a patent that would telegraph all that wrath to the recipient on the other end. The technique uses a myriad of sensors, like an accelerometer, front camera or pressure sensor, to gauge just how emotional a smartphone owner might be and convey that through livelier messaging styles. Get flustered and that BlackBerry Messenger font gets big, bold and red; mellow out with a smile, and the conversation text becomes almost cuddly. Whether or not the patent is granted, let alone used, is very much an unknown. We have a hunch that RIM would rather not make BlackBerry users keep a poker face.
