Benefits of technology

[0008]In an embodiment, a control device registers proximate client devices to a coordinated display group and obtains display capability information for each registered client device. The control device determines to initiate a coordinated display session for outputting visual data via the coordinated display group. The registered proximate client devices execute a synchronization procedure to obtain synchronization information by which the master ap...

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 registers proximate client devices to a coordinated display group and obtains display capability information for each registered client device. The control device determines to initiate a coordinated display session for outputting visual data via the coordinated display group. The registered proximate client devices execute a synchronization procedure to obtain synchronization information by which the master application can derive current relative orientation and position data for each registered proximate client device. The control devices maps a different portion of the visual data to respective display screens of the registered proximate client devices based on the display capability information and synchronization information. The control device delivers the mapped portions of the visual data to the registered proximate client devices for presentation thereon.

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 coordinating a display function 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 different types of wi...
