Abstract
An information handling system presents visual images with a curved display that are corrected for perceptions related to peripheral versus binocular vision of an end user viewing the display. A binocular vision range is defined and scaled with a first scaling factor. A peripheral vision range is defined and scaled with a second scaling factor that compensates for perceptions of movement in an end user's peripheral vision with variable scaling factors applied to adjust for end user head position and gaze based upon detection of the end user by a camera capturing visual images of a viewing area of the display.
Claims20
An information handling system comprising:
- a processor operable to execute instructions that process information;
- a memory interfaced with the processor and operable to store the instructions and information;
- a graphics processing unit interfaced with the processor and operable to render the information as pixel values that define visual images;
- a display interfaced with the graphics processing unit and having a curved panel view area to present the visual images;
- and
- a non-transitory memory storing instructions that when executed cause:
- definition of a binocular vision range at the display;
- definition of a peripheral vision range at the display;
- mapping the visual images to the binocular vision range with first scaling factor;
- mapping the visual images to the peripheral vision range with a second scaling factor that adjusts the first scaling factor to compensate for peripheral vision movement perception;
- and
- presenting the visual images at the display with the first and second scaling factors.
A method for presenting visual images at a curved display, the method comprising:
- defining a binocular vision range at the curved display;
- defining a peripheral vision range at the curved display;
- mapping the visual images to the binocular vision range with first scaling factor;
- mapping the visual images to the peripheral vision range with a second scaling factor that adjusts the first scaling factor to compensate for peripheral vision movement perception associated with the curved display;
- and
- presenting the visual images at the curved display with the first scaling factor in the binocular vision range and the second scaling factor in the peripheral vision range.
A system for presentation of visual images at a curved display, the system comprising:
- a non-transitory memory storing instructions that when executed on a processing resource cause:
- definition of a binocular vision range at the curved display;
- definition of a peripheral vision range at the curved display;
- mapping the visual images to the binocular vision range with first scaling factor;
- mapping the visual images to the peripheral vision range with a second scaling factor that adjusts the first scaling factor to compensate for peripheral vision movement perception associated with the curved display;
- and
- presenting the visual images at the curved display with the first and second scaling factors.
