Abstract
The present invention can include three-dimensional remote control systems that can detect an absolute location to which a remote control is pointing in first and second orthogonal axes and an absolute position of the remote control in a third orthogonal axis. Remote control systems of the present invention can employ absolute position detection with relative position detection. Absolute position detection can indicate an initial absolute position of the remote control and relative position detection can indicate changes in the position of the remote control. By combining absolute and relative position detection, remote control systems of the present invention can track remote controls more precisely than systems that only employ absolute position detection. The present invention also can include methods and apparatus for zooming in and out of an image shown on a display based on the absolute position of the remote control in the third axis.

34. A system coupled to a display, the system comprising:
-
at least one predetermined light source; a photodetector that detects light from the at least one predetermined light source; a remote control having a relative motion sensor; a display; and at least one controller configured to; detect an initial absolute position of the remote control in a first axis based on the light detected by the photodetector; generate signals for rendering at least a portion of an initial image defined by second and third orthogonal axes on the display, wherein the first axis is orthogonal to the second and third axes, and wherein the initial image is scaled to an initial size corresponding to the initial absolute position; detect an updated absolute position of the remote control in the first axis based on a change in position of the remote control detected by the relative motion sensor and based on the initial absolute position; scale the initial image to a new size corresponding to the updated absolute position; and generate signals for rendering at least a portion of the scaled image on the display. - View Dependent Claims (35, 36, 37, 38, 39)

40. A remote control operative for use with a display, the remote control comprising:
-
an absolute position detection component comprising at least one electro-optical component, wherein the absolute position detection component is operative to detect an initial absolute position of the remote control; a relative position detection component operative to detect a change in a position of the remote control; and a controller in communication with the absolute and relative position detection components, wherein the controller is operative to; detect that the remote control is pointing at a particular location on the display based on at least one of data from the absolute position detection component comprising the initial absolute position of the remote control and data from the relative position detection component, wherein the particular location on the display is defined by first and second orthogonal axes; detect an updated absolute position of the remote control in a third axis based on the initial absolute position of the remote control and additional data from the relative position detection component, wherein the third axis is orthogonal to the first and second axes; and transmit signals operative to change a portion of an image on the display corresponding to the particular location based on the updated absolute position of the remote control in the third axis. - View Dependent Claims (41, 42, 43, 44, 45)

46. A method for use with a system having a remote control and a display, the method comprising:
-
rendering an image defined by first and second orthogonal axes on the display; determining an initial absolute position of the remote control in a third axis, wherein the third axis is orthogonal to the first and second axes; receiving at least one signal from a user input component to change the image, wherein the at least one signal comprises data associated with a change in position of the remote control; in response to receiving the at least one signal, determining an updated absolute position of the remote control based on the initial absolute position and the data associated with the change in position of the remote control, wherein the updated absolute position comprises an updated absolute position in the third axis; determining a scale factor for changing the rendered image based on the updated absolute position in the third axis; changing the rendered image by the scale factor; and rendering the changed image on the display. - View Dependent Claims (47, 48, 49, 50, 51, 52, 53)
