An entertainment device for generating augmented reality environments comprises an input for a captured video signal, an image analyser to detect a predetermined marker object location within the captured video signal, a graphics generator to generate a graphics object for integration with the video signal at a selected position to generate an augmented reality image, a controller to positionally couple the graphics object to the detected marker object location within the captured video signal, and a detection failure logic to signal when the image analyser cannot adequately detect the marker object's location within the captured signal. If the logic signals the image analyser cannot detect the location of the marker object within the captured video signal, then the controller positionally decouples the graphics object from the last detected location of the marker object within the video signal, and instructs the graphics generator to modify a characteristic of the graphics object.
