Abstract
A method and a device for generating a control signal for a controllable device are provided. The controllable device has an optical position detection system. At least two images of at least one spatial region are generated with at least one optical detection device of the optical position detection system. Markers are identified in the images and the control signal is generated when a relative position between at least two markers changes. In addition, a marker array and a controllable system are provided.
