Determining a viewing distance for a computing device

摘要

A method, computer readable storage device, and apparatus for determining the distance a computing device is located from a user's face. An image of an individual is obtained. A first pupil location and a second pupil location are identified based on the obtained image. A first distance between the identified first and second pupil location is determined. A second distance between the individual and the computing device is determined based on the determined first distance between the identified first and second pupil locations.

主权项

1. A method, comprising;
obtaining, at a mobile computing device, an image of an individual; identifying, at the mobile computing device, a first pupil location and a second pupil location based on the obtained image; calculating at the mobile computing device, a current first distance between the first pupil location and the second pupil location; comparing, via the mobile computing device, the current first distance to a list of stored, previously measured first distances; determining, at the mobile computing device, a second distance between the individual and the mobile computing device based on what fraction of the stored, previously measured first distances fall below the current first distance.
