Abstract
Eye tracking across multiple displays is supported with re-definition of a gaze vector matrix that correlates a surface of a first display with detected eye gazes as inputs to an information handling system to include a surface of a second display. Eye gazes that correlate to the second display are mapped to the redefined gaze vector matrix, such as with a calibration performed by a user or an estimate derived from tracked eye gazes. The information handling system applies a map of display surface areas to the gaze vector matrix to sort reported eye gazes as at a location of the first display surface, a location of the second display surface or discarded as outside of either display surface.
Claims20
An information handling system comprising:
- a processor operable to process information;
- a memory interfaced with the processor and operable to store the information;
- a graphics controller interfaced with the processor and memory and operable to present the information as visual images at first and second displays;
- a first display interfaced with the graphics controller to present visual images;
- a second display interfaced with the graphics controller to present visual images;
- an eye tracking device coupled to the first display and configured to report eye gaze as a coordinate on the first display from a first set of coordinates defined over a surface of the first display;
- an eye tracking module interfaced with the eye tracking device and the second display, the eye tracking module assigning a second set of coordinates to the eye tracking device, the second set of coordinates defined over at least the surface of the first display and extending over at least part of a surface of the second display, the eye tracking module converting gaze coordinates reported from the eye tracking device into position coordinates at one of the first or second displays;
- a first configuration with the first set of coordinates mapped to only the first display surface;
- and
- a second configuration with the second set of coordinates mapped to both the first display surface and the second display surface, the second set of coordinates including space between the first and second displays.
(canceled)
A method for tracking eye gaze at first and second displays, the method comprising:
- tracking eye gaze at the first display with a single eye tracking device coupled to the first display;
- reporting gaze points from the first display that fall within a gaze vector matrix corresponding with the first display surface;
- adjusting the gaze vector matrix to correspond with the first display surface and a second display surface of a second display, the second display surface spaced apart and separate from the first display surface;
- reporting gaze points from the single eye tracking device that fall within the adjusted gaze vector;
- and
- applying the gaze points as inputs to the first display that correspond to the first display surface and as inputs to the second display that correspond to the second display surface.
A system for tracking eye gaze at plural displays, the system comprising:
- an eye tracking device coupled to a first display and configured to report eye gazes at the surface of the first display to an information handling system;
- and
- non-transitory memory integrated in the information handling system storing instructions that when executed on a processing component:
- configure the eye tracking device to report eye gazes outside of the surface of the first display including at least a portion of a display surface of a second display disposed spaced and separate from the first display;
- map eye gazes reported by the eye tracking device that correspond to the first display as eye gaze inputs to the first display;
- and
- map eye gazes reported by the eye tracking device that correspond to a second display surface area as eye gaze inputs to the second display.
