Abstract

Aspects of the present invention relate to methods and systems for collecting and using eye heading and sight heading information in head worn computing.

Claims

1. A method, comprising:

a. Capturing, from a camera in a head-worn computer, an image of a person in an environment;

b. Processing the image to determine a sight heading of the person in the environment by estimating a relative sight heading of the person and referencing the relative sight heading to a compass heading of the head-worn computer;

c. Estimating a geospatial location for the person in the environment based on the geospatial position of the head-worn computer; and

d. Establishing an object sight line that originates at the estimated geospatial location for the person in the environment and intersects with an object in the environment.

2. A method, comprising:

a. Capturing, from a camera in a head-worn computer, an image series of a person in an environment;

b. Processing the image series to determine a series of sight headings of the person in the environment by estimating, at each portion in the series, a relative sight heading of the person and referencing the relative sight heading to a compass heading of the head-worn computer;

c. Estimating a geospatial location at each portion in the series for the person in the environment based on the geospatial position of the head-worn computer; and

d. Establishing a series of object sight lines that originates at the corresponding estimated geospatial locations for the person in the environment and intersects with an object in the environment to generate a persistence statistic.

3. A method, comprising:

a. Capturing, from a camera in a head-worn computer, an image series of a person at a location in an environment;

b. Processing the image series to determine a series of sight headings of the person in the environment by estimating a series of relative sight headings of the person and referencing the series of relative sight headings to a compass heading of the head-worn computer;

c. Estimating a geospatial location for the person in the environment based on the geospatial position of the head-worn computer; and

d. Establishing a series of object sight lines that originate at the estimated geospatial location for the person in the environment and intersects with an object in the environment to generate a persistence statistic.
