Benefits of technology

The patent describes a system that controls the audio and visual components of a coordinated display session. The system maps different parts of the visual data to different screens and delivers them to the clients for presentation. It evaluates the video content and identifies a specific part of the video that can be highlighted with the audio focus. This allows for a more efficient and effective use of the audio resources during the display session.

Problems solved by technology

However, during playback of visual data (e.g., image data, video data, etc.) each client device is usually limited to outputting the visual data via its own display screen(s).

first embodiment

[0122]At 1810, in a first embodiment, assume that the set of eye tracking devices corresponds to a single master eye tracking device that is responsible for tracking the eye movements of each viewer in the viewing population. In this case, the master eye tracking device can execute a “baselining” operation which establishes the central eye position on the horizontal axis and vertical axis. The “baselining” operation could be triggered as a dedicated “calibration step / moment / time window” during setup of the coordinated display session, irrespective of where the viewing population is expected to be looking at that particular time. Alternatively, the baselining operation can be triggered in association with a prompt that is expected to draw the gazes of the viewing population. For example, a “play / start” touch-screen option may be output by one of the video presentation devices in the viewing population, such as the device designated as the master eye tracking device. In this case, whe...

second embodiment

[0123]At 1810, in a second embodiment, instead of designing at single master eye tracking device, a distributed eye tracking solution can be implemented. In this case, two or more client devices (e.g., potentially all of the video presentation devices participating in the coordinated display session) are designated to perform eye tracking and the two or more designated eye tracking devices establish the horizontal and vertical deviation of the viewer's stare / gaze from the principal and perpendicular axis. Each of the two or more designated eye tracking devices independently acts on the deviation measures therein and attenuates or amplifies the audio stream. In an example, in the distributed eye tracking mode, if there is a 3×3 array (not shown) of video presentation devices and the viewer is looking at the top-right device, other devices would measure horizontal and vertical axis stare / gaze deviation increasing from right to left as well as from top to bottom. In another example, in...

Abstract

In an embodiment, a control device configures audio parameters for an audio component of a coordinated display session. The control devices maps, for proximate client devices registered as presentation devices for the coordinated display session, a different portion of visual data for the coordinated display session to respective display screens, and delivers the mapped portions of the visual data to the proximate client devices for presentation by the respective display screens during the coordinated display session. The control device evaluates video content data within the mapped portions of the visual data, identifies a subset of the mapped portions as a target for an audio focus of the coordinated display session based on the evaluation and reconfigures the audio parameters so as to transition the audio focus of the coordinated display session to the identified subset.

Description

CLAIM OF PRIORITY UNDER 35 U.S.C. §119[0001]The present application for patent claims priority to Provisional Application No. 61,813,891, entitled “COORDINATING A DISPLAY FUNCTION BETWEEN A PLURALITY OF PROXIMATE CLIENT DEVICES”, filed Apr. 19, 2013, by the same inventors as the subject application, assigned to the assignee hereof and hereby expressly incorporated by reference herein in its entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]Embodiments of the invention relate to configuring audio for a coordinated display session between a plurality of proximate client devices.[0004]2. Description of the Related Art[0005]Wireless communication systems have developed through various generations, including a first-generation analog wireless phone service (1G), a second-generation (2G) digital wireless phone service (including interim 2.5G and 2.75G networks) and a third-generation (3G) high speed data, Internet-capable wireless service. There are presently many d...
