20090287987 | NON-DESTRUCTIVE MEDIA PRESENTATION DERIVATIVES - The claimed subject matter relates to various architectures that can, inter alia, facilitate creation of a synch file as well as facilitate interpretation of the synch file. Both creation and interpretation can be accomplished in conjunction with an original media asset. The synch file can include transformation commands that can operate on a presentation of the asset rather than upon the asset itself. Accordingly, what is actually perceived by a content consumer during a presentation of the asset need not be exactly what the asset creator fixed in a tangible medium. Rather, the content consumer can observe a derivative media presentation based upon interpretation of the synch file. | 11-19-2009 |
20100277411 | USER TRACKING FEEDBACK - Technology is presented for providing feedback to a user on an ability of an executing application to track user action for control of the executing application on a computer system. A capture system detects a user in a capture area.

One example of such factors is a user being out of the field of view of the capture system. Some other factor examples include lighting conditions and obstructions in the capture area. Responsive to a user tracking criteria not being satisfied, feedback is output to the user. In some embodiments, the feedback is provided within the context of an executing application. | 11-04-2010 |
