Abstract

An information system having a plurality of user options is provided. A graphical representation is uniquely associated with each user option. In response to a single user action, the graphical representations are successively displayed in a focus area within the display screen. When the user sees a graphical representation of a desired option, the user takes some additional action and the successive display of graphical representations is discontinued. The graphical representation of the desired user option is then displayed in the focus area within the display screen, and may be visually enhanced. Once navigation has been discontinued, the user may select the user option associated with the displayed graphical representation.

Claims

1. A method for navigating a plurality of options within a user interface of an interactive television system, the method comprising:

storing a graphical representation of each of the plurality of options;

in response to a single user action, scrolling a sequence of the graphical representations in a straight line through a single, non-moving focus area of the user interface, the focus area being located in an intermediate position between two ends of the straight-line sequence; and

in response to a terminating action by the user, discontinuing the scrolling of graphical representations to show a particular graphical representation of an option in the focus; and

testing the user'"'"'s ability to identify a test image within the sequence of images displayed at different rates to automatically determine the user'"'"'s maximum image recognition threshold and set the rate at which the sequence is scrolled based on that threshold.

2. The method of claim 1, wherein at least one graphical representation comprises an icon.

3. The method of claim 1, wherein at least one graphical representation comprises an image.

4. The method of claim 1, wherein at least one graphical representation comprises a video frame.

5. The method of claim 1, further comprising replacing the graphical representation in the focus area after the terminating action with a reduced-size version of a television program being shown on the corresponding option prior to an explicit selection action by the user to display the television program.

6. The method of claim 1, wherein a displayed graphical representation occupies between about one-fifth and about one-fourth of a display screen on which the user interface is displayed.

7. The method of claim 1, wherein the graphical representations are successively displayed in a center portion of the user interface.

8. The method of claim 1, wherein the single user action comprises pressing and holding down a control on a remote control.

9. The method of claim 8, wherein the terminating action comprises releasing the control on the remote control.
