The position of an object (11, 12), such as a part of a body or an optionally coloured object being manipulated by a user, is established within a frame, e.g. an image frame, for example by the acquisition of images. The shape (e.g. an ellipse or rounded rectangle) of the field of movement (16) of the object is defined and a bounding rectangle defines the shape of the field of movement. A coordinate from within the object is mapped to the bounding rectangle, then the coordinate is mapped from the bounding rectangle to the image frame, which may be a rectangle. The coordinate is then snapped from the image frame to the target, e.g. a monitor screen. The coordinate (11', 12') may be displayed on a computer monitor (15) as an icon. The foregoing may provide a user interactive game capable of training and monitoring motor and cognitive skills of a patient, e.g. hand motion trajectory or range. |
