Drawing, writing or pointing device (1) for use with data presentations, computer supported work or other interactive use of a computer. The device (1) comprises one or more code patterns (3). Each code pattern (3) is adapted to be detected by a camera and recognition system (13). A camera and recognition system (13) adapted to cooperate with the device (1) records one or more images (31). At least one image contains one or more code patterns (3) from the device(s). Drawing, writing and pointing devices (1) are used in a system (40) and in a method for drawing, writing and pointing at data presentations, computer supported work and other interactive use of a computer where the position and orientation of the device (1) is determined and transferred to a computer. The drawing, writing and pointing device (1) is also used in a method for continuously recording the position and orientation of one or more marked objects, where the marking comprises one or more code patterns (3).
