Image sequences are accessed, the sequences each taken, from a different perspective, of a portion of a radiation region defined by projected electromagnetic radiation. The image sequences each include a projection image taken during an emitting period in which the projected electromagnetic radiation is emitted, the projection image being of ambient electromagnetic radiation and of an object within the portion being illuminated with the projected electromagnetic radiation, and an ambient image taken during an extinguishing period in which the projected electromagnetic radiation is extinguished, the ambient image being of the ambient electromagnetic radiation. A position of the object using the projection images and the ambient images is determined, an application is controlled based on the determined position. |
