Abstract
Eyewear including a sensor integrated into frame of eyewear. In one example, the sensor comprises a strain gauge, such as a metallic foil gauge, that is configured to sense and measure distortion of the frame when worn by a user and under different force profiles, by measuring a strain in the frame when bent. The measured strain by strain gauge is sensed by a processor, and the processor performs dynamic calibration of image processing based on the measured strain. The distortion measured by the strain gauge is used by the processor to correct calibration of the cameras, and the displays.
Claims20
Eyewear, comprising:
- a frame;
- a sensor coupled to the frame configured to sense distortion of the frame and generate a sensor signal;
- a camera coupled to the frame and configured to capture a camera image having pixels;
- a display supported by the frame and configured to display a display image having pixels;
- and
- an electronic processor configured to:
- receive the sensor signal;
- calibrate the camera image as a function of the sensor signal;
- and
- display the display image.
A method for use with eyewear, the eyewear having a frame, a sensor coupled to the frame configured to sense distortion of the frame and generate a sensor signal, a camera coupled to the frame and configured to capture a camera image having pixels, a display supported by the frame and configured to display a display image having pixels, and an electronic processor:
- receiving the sensor signal;
- calibrating the camera image as a function of the sensor signal;
- and
- displaying the display image on the display.
A non-transitory computer-readable medium storing program code which, when executed, is operative to cause a processor of eyewear having a frame, a sensor coupled to the frame configured to sense distortion of the frame and generate a sensor signal, a camera coupled to the frame and configured to capture a camera image having pixels, and a display supported by the frame and configured to display a display image having pixels to perform the steps of:
- receive the sensor signal;
- calibrate the camera image as a function of the sensor signal;
- and
- display the display image on the display.
