Wearable bionic-lens optics hardware calibration/UX (Smithwick).
The present disclosure relates to calibration, customization, and improved user experiences for smart or bionic lenses that are worn by a user. The calibration techniques include detecting and correcting distortion of a display of the bionic lenses, as well as distortion due to characteristics of the lens or eyes of the user. The customization techniques include utilizing the bionic lenses to detect eye characteristics that can be used to improve insertion of the bionic lenses, track health over time, and provide user alerts. The user experiences include interactive environments and animation techniques that are improved via the bionic lenses.
FIELD (1) The present disclosure relates generally to bionic contact lenses worn on a user's eye. BACKGROUND (2) Bionic contact lenses, such as a smart contact lenses, that are worn or inserted into the eyes of users are quickly developing. Generally, these lenses may include circuitry and sensors that provide or generate information that can be displayed direct into the user's eye. For example, some bionic contact lenses include displays that generate images presented directly into a user's eye. Some bionic lenses also include integrated cameras that capture images from approximately the same viewpoint as the user. Many technology fields, such as alternate reality and virtual reality technologies, are looking to leverage the lenses for new applications and techniques. For example, with AR/VR applications, the display on the bionic lens generates images that can be directly overlaid with the user's “real world” vision, since the image formed by the light from the display is projected, along with light from the world, onto the user's retinas, forming the user's view. However, to operate accurately and provide an immersive user experience, the calibration and accuracy of the bionic lenses is important, current lenses may not be accurately calibrated, hindering the user experience. (3) Additionally, certain aspects of the lenses can be leveraged to further increase the user immersion, as well as provide important and useful tools for the applications utilizing bionic lenses. SUM
1. A method to determine eye characteristics of a user wearing one or more bionic lenses comprising: capturing by a first bionic lens worn in a first eye of the user a first image corresponding to a calibration pattern positioned at a first relative orientation of the calibration pattern to the user; capturing by the first bionic lens a second image corresponding to the calibration pattern positioned at a second relative orientation of the calibration pattern to the user; and analyzing the first image and the second image by a processor to determine the eye characteristics of the user by: comparing a known characteristic of the calibration pattern to a characteristic of a representation of the calibration pattern in the first image and the second image; and determining a difference between the known characteristic and the characteristic of the representation of the calibration pattern. ||
