Gaze tracking system
First Claim
Patent Images
1. A method comprising:
- receiving scene images from a head mounted gaze tracking device capturing external scenes viewed by a user wearing the head mounted device, the scene images received at a server via a network;
receiving gaze direction information from the head mounted gaze tracking device along with the scene images, the gaze direction information indicating where in the external scenes the user was gazing when viewing the external scenes, the gaze direction information received at the server via the network;
executing an image recognition algorithm on the scene images to identify items within the external scenes viewed by the user;
generating a gazing log tracking the identified items viewed by the user;
performing latent pre-searches on at least a portion of the items viewed by the user to generate latent search results, wherein the latent pre-searches are automatically triggered while the associated items are in the user'"'"'s peripheral view and without affirmative requests on a per search basis by the user; and
caching the latent search results.

Abstract
A gaze tracking technique is implemented with a head mounted gaze tracking device that communicates with a server. The server receives scene images from the head mounted gaze tracking device which captures external scenes viewed by a user wearing the head mounted device. The server also receives gaze direction information from the head mounted gaze tracking device. The gaze direction information indicates where in the external scenes the user was gazing when viewing the external scenes. An image recognition algorithm is executed on the scene images to identify items within the external scenes viewed by the user. A gazing log tracking the identified items viewed by the user is generated.
