Embodiment Construction

[0025] The present invention relates to a method and system for estimating a user's line of sight and / or for estimating (relative or absolute) motion of a user's line of sight based on differences in line of sight between image samples, at least one of which captures The user's eyes (eg, by capturing the user's eye area, face, upper body, or even body).

[0026] The difference in line of sight can then be used to estimate the user's line of sight by relying on the (given or known) line of sight of the reference image. Accordingly, the method and system rely on estimating differences in line of sight captured in multiple images, rather than estimating line of sight directly from images with the user's eyes.

[0027] The difference in line of sight between a reference image paired with a known line of sight and an input image without a known line of sight can be used to synthesize the known line of sight and the estimated line of sight difference by synthesizing the reference sa...

Abstract

The invention concerns a method for estimating a gaze at which a user is looking at. The method comprises a step of retrieving an input image and a reference image of an eye of the user and / or an individual.The method comprises then a step of processing the input image and the reference image so as to estimate a gaze difference between the gaze of the eye within the input image and the gaze of the eye within the reference image. The gaze of the user is the retrieved using the estimated gaze difference and the known gaze of the reference image. The invention also concerns a system for enabling this method.

Description

technical field [0001] The present invention relates to a method and system for estimating a user's line of sight, especially for human-computer interaction, virtual reality, healthcare and mobile applications. [0002] The invention also relates to a method and system for estimating the movement of a user's gaze. Background technique [0003] Gaze (ie, the point at which the user is looking and / or the line of sight relative to his eyes) is an important cue for human behavior. Gaze and its movement are indicators of visual attention as well as a person's particular state of mind and state of mind. [0004] Gaze estimation thus provides support for areas such as Human-Robot Interaction (HRI), Virtual Reality (VR), Social Interaction Analysis or Healthcare. With the development of sensing capabilities on mobile phones, line-of-sight estimation can also support a wider range of applications in mobile scenarios. [0005] Line of sight can be modeled in a number of ways depend...
