A computer interface allows as user to control aspects of its behavior by head motion. In one example, a head mounted display (HMD) includes a directional detector for generating an object detection signal when pointed at certain physical objects. The detector is mounted so users can point it by moving their heads. In another example, a graphical user interface includes the computation of a view space comprised of multiple separate portions, in each of which graphical user interface windows generated by separate computer processes can be selectively located by a user. The user can selectively move such windows between view space portions by a point and click interface. The method displays a subset of view space portions to the user at one time, senses motion of the user's head, and changes the portions of the view space displayed, in discrete units of view space portions, in response to changes in the position of the user's head. In still another example, a graphical user interface includes: computing a visual space; displaying a subset of space to the user, sensing user motion, including monitoring motion of a user's head, so as to divide head motions into at least a first and second class; and allowing a user to navigate through the visual space in response to head motions of said first class, while substantially ignoring head motions of the second class for such purposes.
