Claim 14

An information presentation system configured to present information to a user; said system having a display device, an audio reproduction mechanism and a gaze-tracking device for determining a gaze position on said display device; said system comprising: a display mechanism configured to display a first information on said display device resulting in a captioned image on said display device; a detection mechanism configured to detect an intersection of said gaze position and said captioned image displayed on said display device; an association mechanism configured to associate an additional information with said first information after said detection mechanism detects said intersection, said additional information being caption information; and a presentation mechanism configured to present said additional information as sound to said user using said audio reproduction mechanism.

Claim 15

The information presentation system of claim 11 wherein said additional information is an audio data.

Claim 16

The information presentation system of claim 11 wherein said additional data is textual data and said presentation mechanism further comprises: a text-to-sound mechanism configured to convert said textual data to an audio data.

Claim 17

The information presentation system of claim 13 further comprising: a caption detection mechanism configured to detect a caption linkage embedded within said first information; and a caption access mechanism configured to use said caption linkage to access said textual data.

Claim 18

The information presentation system of claim 13 further comprising: an area determination mechanism configured to detect an area of interest containing said captioned image; said area of interest separated from other displayed information. a caption location mechanism configured to locate caption text within said area of interest; and an extraction mechanism configured to extract said textual data from said caption text.

Claim 19

A computer program product comprising: (a) a computer usable storage medium having computer readable code embodied therein for causing a computer to present information to a user; said computer readable code comprising: (b) computer readable code configured to cause said computer to effect a display mechanism configured to display a first information on said display device resulting in a captioned image on said display device; computer readable code configured to cause said computer to effect a detection mechanism configured to detect an intersection of a gaze position and said image displayed on said display device; said gaze position determined from a gaze-tracking device; computer readable code configured to cause said computer to effect an association mechanism configured to associate an additional information with said first information after said detection mechanism detects said intersections, said additional information being caption information; and computer readable code configured to cause said computer to effect a presentation mechanism configured to present said additional information as sound to said user using an audio reproduction mechanism.
