A method for validating a control operation to be performed by a target device through a virtual control interface. The virtual control interface is displayed by a head mounted device. A selection instruction of a first area is detected, delivering a first area. A position of gaze is detected, delivering a second area within the virtual control interface. It is detected if the first area and the second area are at least partially overlapping a same dedicated area associated to a control operation to be performed by the target device. In case of detection of an occurrence of the first area and the second area at least partially overlapping, the control operation is validated.
