Abstract: The process may include receiving a content request. The content request may include a content characteristic preference. The process may include generating a first content stream segment. The first content stream segment may include a first characteristic quality. The process may also include outputting the first content stream segment via a playback device, and the process may include receiving biometric data regarding a user perceiving the output. The process may also include identifying a characteristic modification. The process may further include generating a second content stream segment. The second content stream segment may have a second characteristic quality. The second characteristic quality may be the result of applying the characteristic modification to the first characteristic quality. The process may further include outputting the second content stream segment on the playback device such that the first and the second segments may be perceived by the user as a continuous content stream.

Abstract: A method of identifying content and tracking viewership thereof comprising measuring a color content of a display device, defining a measured color content and determining an occupancy of a space associated with the display device, defining a determined occupancy. Where the determined occupancy indicated the occupancy by at least one person, the measured color content with is associated with the viewable content. Additionally, a viewership information database is updated responsive to the determined occupancy and the viewable content. In some embodiments, determining the color content may be performed by a luminaire in optical communication with the display device.
