Abstract: A method for gesture based human-machine interaction comprises determining an environmental status of an electronic device and operating the electronic device in one of at least two gesture modes depending on the environmental status. During a first gesture mode, detection of gestures of a first set of gestures is enabled. The method further comprises detecting a movement of an object and, when operating in the first gesture mode, determining if the detected movement corresponds to a gesture of the first set of gestures. The method further comprises, if the detected movement corresponds to a gesture of the first set of gestures, carrying out a first command of the electronic device associated to the gesture corresponding to the detected movement.

Abstract: A method of managing a multi-application electronic device, such as a multi-application smart card, of the type having an operating system which is designed to support a plurality of applications. Each of the applications belongs to an application provider having a unique security domain which is initially installed on the card. Upon receipt of a command for an application to be loaded onto the device, the operating system verifies that the application is associated with a security domain corresponding to the security domain of the application provider. In the event of successful verification, the operating system authorizes the loading and installation thereof on the card, connecting the same automatically to the security domain.
