Characterizing dynamic regions of digital media data
First Claim
Patent Images
1. A computer-implemented method comprising:
- defining a dynamic region in two or more frames of a digital media segment comprising a portion of a digital media file and being defined by at least two time markers comprising a start time and an end time, the dynamic region containing at least part of a visible feature in the one or more frames;
analyzing a relationship between an external data set that is collected from one or more subjects viewing the digital media segment and the dynamic region, the external data set comprising eye-tracking data for the one or more subjects; and
reporting a metric indicative of a subject interest level in the visible feature, the reporting of the metric comprising plotting the external data set in conjunction with a display frame selected from the two or more frames to produce a snapshot comprising screen locations gazed at by the one or more subjects while viewing the digital media segment and the dynamic region, the snapshot comprising a still image of the display frame overlaid with one or more series of connected points that show the screen locations gazed at by the one or more subjects while viewing the two or more frames.

Abstract
A media analysis tool is provided for defining dynamic regions of a digital media segment. The dynamic regions may contain at least part of a visible feature of the segment. Correlation of the defined regions with external data quantifying attention of a subject viewing the segment to locations on the screen provides measures of interest level and attention to visible features in the segment. The dynamic regions may be defined in only some of the frames of a segment. The dynamic region may be interpolated or extrapolated for frames in which it is not explicitly defined.

10. A computer-implemented method comprising
displaying, to a subject, a digital media segment comprising a portion of a digital media file that comprises a plurality of frames, the digital media segment being defined by at least two time markers comprising a start time and an end time; -
recording a data set comprising screen locations gazed at by the subject while viewing the digital media segment; selecting a display frame from the plurality of frames; and plotting the data set in conjunction with the display frame to produce a snapshot comprising screen locations gazed at by the subject while viewing the digital media segment, the snapshot comprising a still image of the display frame overlaid with a series of connected points that show the screen locations gazed at by the subject while viewing the plurality of frames. - View Dependent Claims (11, 12, 13, 14)
