Abstract: A system for contextualizing disorganized content (2a) captured from any live session (1) using external devices 30-xd to first detect & record 30-1 session activities (1d) being conducted by session attendees (1c). Activities (1d) become normalized tracked object data 2-otd for differentiation 30-2 into normalized session marks 3-pm denoting thresholded activity (1d) changes. Normalized marks 3-pm are integrated 30-3 into normalized events 4-pe using a “mark creates, start or stops event” model. Events 4-pe may be synthesized 30-4 via waveform convolution forming new combined events 40se, or used as containers to summarize the occurrences of marks 3-pm or other events 4-pe, the results of which create new summary marks 3-sm. Calculation marks 3-tm may also be synthesized 30-4 for sampling various session data at various session times. During content expression 30-5 events 4-pe and 4-se can be automatically named and foldered creating index (2i) and organized content (2b).
