Abstract
Adaptive Control Systems and methods are provided for an electronic visual aid, which may be wearable, hand held or fixed mount, including autonomous hands free control integrated with artificial intelligence tunable to user preferences and environmental conditions.
Claims27
A method of providing enhanced vision for a low-vision user, comprising the steps of:
- receiving real-time video images with a visual aid device;
- identifying, with the visual aid device, a subset of each of the real-time video images corresponding to a focus of attention of the low-vision user;
- extracting, with the visual aid device, structures of interest within the subset of each of the real-time video images;
- examining the extracted structures of interest with the visual aid device;
- and
- discarding structures of interest that include parameters that are outside of pre-selected bounds identifying, with the visual aid device, at least one group of structures of interest that are organized in a row or column;
- determining, with the visual aid device, a dimension of the at least one group of structures of interest;
- adjusting, with the visual aid device, a magnification of the at least one group of structures of interest to match a preferred structure dimension;
- forming, with the visual aid device, an enhanced video stream that includes the real-time images and the at least one group of structures of interest with adjusted magnification;
- and
- displaying the enhanced video stream on a display of the visual aid device.

- extracting, with the visual aid device, structures of interest within the subset of each of the real-time video images;
- determining, with the visual aid device, a dimension of the at least one group of structures of interest;
- determining, with the visual aid device, a statistical confidence that the at least one group of structures of interest are organized in a row or column;
- adjusting, with the visual aid device, a magnification of the at least one group of structures of interest to match a preferred structure dimension, wherein adjusting a magnification of at least one group of structures of interest further comprises adjusting a magnification of the at least one group of structures of interest to match the preferred structure size when the statistical confidence is above a confidence threshold;
- forming, with the visual aid device, an enhanced video stream that includes the real-time images and the at least one group of structures of interest with adjusted magnification;
- and
- displaying the enhanced video stream on a display of the visual aid device.

A method of providing enhanced vision for a low-vision user, comprising the steps of:
- obtaining real-time video images with a camera of a visual aid device;
- sensing a motion component of the visual aid device as it obtains the real-time video images;
- determining a motion state of the visual aid device based on the sensed motion component;
- receiving the real-time video images from the camera with a visual aid device;
- identifying, with the visual aid device, a subset of each of the real-time video images corresponding to a focus of attention of the low-vision user;
- extracting, with the visual aid device, structures of interest within the subset of each of the real-time video images;
- determining, with the visual aid device, a dimension of the at least one group of structures of interest;
- adjusting, with the visual aid device, a magnification of the at least one group of structures of interest to match a preferred structure dimension only if the motion state comprises a focused attention state;
- forming, with the visual aid device, an enhanced video stream that includes the real-time images and the at least one group of structures of interest with adjusted magnification;
- and
- displaying the enhanced video stream on a display of the visual aid device only if the motion state comprises a focused attention state.
