The invention describes a method for control of a device (D<SUB>1</SUB>, D<SUB>2</SUB>, D<SUB>3</SUB>, D<SUB>4</SUB>), which method comprise aiming a pointing device ( 2 ) comprising a camera ( 3 ) at an object (B<SUB>1</SUB>, B<SUB>1</SUB>', B<SUB>2</SUB>, B<SUB>3</SUB>, B<SUB>4</SUB>) representing a property of the device (D<SUB>1</SUB>, D<SUB>2</SUB>, D<SUB>3</SUB>, D<SUB>4</SUB>) to be controlled and manipulating a control input ( 4 ) on the pointing device ( 2 ) to specify a degree of change ( 5 ) for the property. An image ( 6 ) of a target area (A) aimed at by the pointing device ( 2 ) is generated by the camera ( 3 ). The target area image ( 6 ) is interpreted to identify the chosen object (B<SUB>1</SUB>, B<SUB>1</SUB>', B<SUB>2</SUB>, B<SUB>3</SUB>, B<SUB>4</SUB>), and to deduce the property of the device (D<SUB>1</SUB>. D<SUB>2</SUB>, D<SUB>3</SUB>, D<SUB>4</SUB>) to be controlled based on the chosen object (B<SUB>1</SUB>, B<SUB>1</SUB>', B<SUB>2i </SUB>B<SUB>3</SUB>, B<SUB>4</SUB>). A control signal ( 7 ) is then generated for the device (D<SUB>1</SUB>, D<SUB>2</SUB>, D<SUB>3</SUB>, D<SUB>4</SUB>) to be controlled accord üng to the degree of change ( 5 ) for the deduced property. The invention also describes a pointing device ( 2 ), a device control interface ( 8, 8' ) and a system comprising such a pointing device ( 2 ) and device control interface ( 8, 8' ) suitable for applying this method.
