Patent number: 9239624Abstract: A free hand gesture control user interface is described. Components of the interface system may include a stereo vision camera, or multiple cameras, a control unit, a projector and a projecting surface. In an automotive application, the projecting surface may be the windscreen in the vehicle or a mounted screen. The camera together with software modules in the control unit define a gesture acceptance border and a gesture acceptance space within which hand gestures may be imaged, defined for various control actions, and executed. The hand images are analyzed in slices of the gesture acceptance space to determine hand orientation (open or closed) and/or motion.Type: GrantFiled: April 13, 2012Date of Patent: January 19, 2016Assignee: Nokia Technologies OyInventors: Kongqiao Wang, Leo Kärkkäinen

Patent number: 8583148Abstract: An apparatus may include a messaging module configured to suggest a message segment in order to draft a message. A contextual characteristic determiner may be used to determine contextual characteristics of the apparatus, the recipient of a call, and/or the user of the apparatus and thereby the messaging module may suggest the message segment based on the contextual characteristics. The contextual characteristics may include user emotions, which may be recognized by an emotion recognizer. Message segments may also be based on prior messaging history. Thereby, the apparatus may suggest message segments in order to more easily draft messages when, for example, initiating or responding to attempted voice communications. Further, the apparatus may include a reminder scheduler which is configured to schedule a reminder to respond to an attempted voice communication.Type: GrantFiled: June 7, 2010Date of Patent: November 12, 2013Assignee: Nokia CorporationInventors: Elina Ollila, Mika Rautava, Leo Kärkkäinen
