Abstract
A display KVM switch interfaces with peripheral input devices, such as keyboard and a mouse, to selectively switch inputs from the input devices to one of plural information handling systems simultaneously presenting visual images at the display. A camera monitors a viewing position of the display to detect end user gaze at a first area of the display that shows first visual images of a first information handling system and at a second area of the display that shows visual images of a second information handling system. Inputs are switched between the information handling systems when a gaze is detected at an area presented by the information handling system after a predetermined time period.
Claims20
An information handling system comprising:
- a first housing having a first processor and a first memory cooperatively interfaced to execute instructions that process first information;
- a second housing having a second processor and a second memory cooperatively interfaced to execute instructions that process second information;
- a display interfaced with the first processor and the second processor to selectively present the first information as first visual images at a first area of the display and the second information as second visual images at a second area of the display;
- a camera interfaced with the display and aligned to capture a visual image of an end user viewing the display;
- a peripheral mouse interfaced with the display and operable to detect end user cursor inputs and communicate the cursor inputs to the display;
- a switch coupled to the display and interfaced with the peripheral mouse, the switch operable to selectively communicate the cursor inputs to one of the first processor and the second processor;
- a display controller coupled to the display to manage presentation of the first visual images and second visual images at the display, the display controller interfaced with the camera and the switch;
- and
- a non-transitory memory interfaced with the display controller and storing instructions that when executed on the display controller cause the peripheral mouse cursor inputs to be communicated to the first processor when the camera captures a first predetermined end user gaze at the first visual images in the first area of the display for processing by the first processor across the entire display and to be communicated to the second processor when the camera captures a second predetermined end user gaze at the second visual images in the second area of the display for processing by the second processor across the entire display.
A method for managing inputs to an information handling system, the method comprising:
- presenting visual images at a display in a first area from a first information handling system;
- presenting visual images at the display in a second area from a second information handling system;
- interfacing a peripheral input device to the display;
- selecting the first information handling systems to receive inputs from the peripheral input device across the entire display when a predetermined end user gaze is detected at the first area;
- and
- selecting the second information handling system to receive inputs from the peripheral input device across the entire display when the predetermined end user gaze is detected at the second area.
A system for managing inputs to an information handling system, the system comprising:
- a display operable to simultaneously present visual images from plural information handling systems including at least first visual images of a first information handling system presented in a first area and second visual images of a second information handling system presented in a second area;
- a camera interfaced with the display and aligned to capture a visual image of an end user viewing the display;
- an input device interfaced with the display and operable to detect end user inputs and communicate the inputs to the display;
- a switch coupled to the display and interfaced with the input device, the switch operable to selectively communicate the inputs to one selected of the plural information handling systems at a time;
- a display controller coupled to the display to manage presentation of the visual images, the display controller interfaced with the camera and the switch;
- and
- a non-transitory memory interfaced with the display controller and storing instructions that when executed on the display controller cause the inputs to be communicated to the first information handling system across the entire display when the camera captures a first predetermined end user gaze at the first visual images in the first area and to be communicated to the second information handling system across the entire display when the camera captures a second predetermined end user gaze at the second visual images in the second area.
