The directionality of an event that progresses in isolation is unidirectional; it is a “closed event.” The direction within a closed event tends to lose its propulsive force, making sustainability difficult. There are two conceivable ways to maintain this momentum. The first is to expand unidirectional directionality into a multi-dimensional framework—be it bidirectional or multidirectional. The former is generally more desirable due to its higher degree of controllability.
This concept is easily illustrated by comparing solitary study to group learning, or traditional television and radio broadcasting to interactive internet streaming. The second method is a contingency for when opening an event is difficult—for instance, when continuous solitary study is required or when unidirectional communication is unavoidable. This approach involves operating in multiple layers without altering the orientation of the directionality.
If the orientation of directionality is changed, the event becomes “open.” In a closed event, the orientation remains fixed. Given this, “operating in multiple layers” means, for example, regenerating propulsive force by manipulating time lags or temporal divisions. Examples include keeping a diary to reflect upon later or maintaining a learning log.
In broadcasting, one might consider using certain tools: implementing a program schedule or partitioning events to reignite momentum. These techniques are frequently employed in classical television and radio. When the continuity of an event becomes difficult, whether it is “open” or “closed” serves as a vital indicator for determining its ideal form.
Of course, when one grapples with the fundamental question of where and how to place this directionality in the first place, the issue precedes the opening or closing of events. Personally, I find this to be the greater struggle, but that is a matter for another time.
