Abstract
Disclosed is a control device querying a preset data set to obtain color vision sensitivity information corresponding to acquired identity information of a user of the augmented reality device; the control device judging whether the user is a color recognition disorder patient according to obtained color vision sensitivity information; the control device acquiring a personalized color display mode corresponding to the color vision sensitivity information as a target color display mode when the user is judged as a color recognition disorder patient; and the control device providing the augmented reality device with the target color display mode so that the augmented reality device employs the target color display mode to display an image.
Claims17
A method for controlling display of an augmented reality device, comprising:
- querying, by a control device, a preset data set to obtain color vision sensitivity information corresponding to acquired identity information of a user of the augmented reality device;
- judging, by the control device, whether the user is a color recognition disorder patient according to obtained color vision sensitivity information;
- acquiring, by the control device, a personalized color display mode corresponding to the color vision sensitivity information as a target color display mode when the user is judged as a color recognition disorder patient;
- and
- providing, by the control device, the augmented reality device with the target color display mode so that the augmented reality device employs the target color display mode to display an image and the displayed image comprises virtually-displayed content;
- wherein before providing the augmented reality device with the target color display mode, the method further comprises:
- acquiring ambient brightness information and user's visual field environment color information detected by the augmented reality device;
- generating a compensation parameter for each sub-pixel in the image according to the color vision sensitivity information, the ambient brightness information and the user's visual field environment color information so as to increase contrast between colors of the virtually-displayed content that is a foreground and colors of the user's visual field environment that is a background,
- performing compensation for a data signal of each sub-pixel according to the compensation parameter of each sub-pixel, and generating a compensated data signal;
- and
- providing the compensated data signal together with the target color display mode to the augmented reality device so that the augmented reality device employs the target color display mode to display the image based on the compensated data signal.

A control device, comprising:
- a query device implemented by a hardware unit and configured to query a preset data set to obtain color vision sensitivity information corresponding to acquired identity information of a user of an augmented reality device;
- a judger implemented by a hardware unit and configured to judge whether the user is a color recognition disorder patient according to obtained color vision sensitivity information;
- a color mode acquirer implemented by a hardware unit and configured to acquire a personalized color display mode corresponding to the color vision sensitivity information as a target color display mode when the judger judges that the user is a color recognition disorder patient, and provide the augmented reality device with the target color display mode so that the augmented reality device employs the target color display mode to display an image and the displayed image comprises virtually-displayed content;
- and
- a compensator implemented by a hardware unit and configured to generate a compensation parameter for each sub-pixel in the image according to the color vision sensitivity information and ambient brightness information and user's visual field environment color information detected by the augmented reality device so as to increase contrast between colors of the virtually-displayed content that is a foreground and colors of the user's visual field environment that is a background;
- perform compensation for a data signal of each sub-pixel according to the compensation parameter for each sub-pixel to generate a compensated data signal;
- and provide the compensated data signal together with the target color display mode to the augmented reality device, so that the augmented reality device employs the target color display mode to display the image based on the compensated data signal.
4 more elements
An augmented reality device, comprising:
- a display configured to display an image in a color display mode, a displayed image comprising virtually-displayed content;
- a display mode setter implemented by a hardware unit and configured to set a color display mode for the display, the color display mode comprising at least one personalized color display mode in a case where a user of the augmented reality device is a color recognition disorder patient and a standard color display mode in a case where the user is a normal color recognizer;
- and
- a detector configured to detect ambient brightness information and user's visual field environment color information, and provide the detected information to a control device so that the control device generates a compensated data signal for each sub-pixel of the image based on the color vision sensitivity information and the ambient brightness information and the user's visual field environment color information so as to increase contrast between colors of the virtually-displayed content that is a foreground and colors of the user's visual field environment that is a background;
- wherein the display mode setter is configured to receive a target color display mode from the control device and set it as a color display mode for the display, the target color display mode corresponding to color vision sensitivity information of the user of the augmented reality device, and the display is further configured to employ the received target color display mode to display the image based on the compensated data signal based on the compensated data signal from the control device.
