Abstract: A method may include projecting, by a device, content on a surface, determining an orientation of the device, detecting a movement of the device, determining an operation that corresponds to the movement and interacts with the content, and performing the operation.

Abstract: A communication terminal is disclosed, comprising a first audio input/output element arranged in vicinity of a first end of a body of the communication terminal; a second audio input/output element arranged in vicinity of a second end of the body of the communication terminal; an accelerometer arranged to determine force applied on a mass in the communication terminal, wherein the first and second audio input/output elements are each arranged for selectable performance as microphone or speaker such that depending on the determined force on the mass, one of the first and second audio input/output elements is assigned for speaker operation, and the other for microphone operation. A method and computer program are also disclosed.

Abstract: A headset for an electronic device includes an audio output device including a left ear piece and a right ear piece, and a plurality of transducers each operable to provide a signal corresponding to at least one of motion or vibration of at least a portion of the headset. One transducer of the plurality of transducers is associated with the left ear piece and another transducer of the plurality of transducers is associated with the right ear piece. The headset further includes circuitry operatively coupled to the plurality of transducers, wherein the circuitry is configured to generate a control signal for use by the headset or the electronic device based on the respective signals.

Abstract: A user interface is disclosed, comprising a sensor arranged to determine a spatial change, said user interface being arranged to control at least one function, wherein the function is controlled by said determined spatial change. Further, an apparatus, a method, and a computer program for controlling a function are disclosed.

Abstract: The invention relates to a headset comprising a housing with an earphone and at least one user interface input or output function, said headset also comprising a fastening element arranged for positioning the headset close to a person's ear during use. According to the invention, said headset furthermore comprises an accelerometer arranged for detecting the orientation in at least one dimension of said housing, said accelerometer being associated with a headset control unit which is arranged for configuring a function of said user interface input or output function depending on said orientation of the housing.
