COMMONSENSE DESCRIPTIONS Of REALITY

 Actually, in any visual data, there is infinite data. So what should we describe?

A basic question is - when we see reality (a video, a scene) what in it do we describe when we have to do so?

We describe 3 things (when there is no specific question asked to answer about that piece of reality). So in "default", commonsense contexts, we describe 3 things -

1) all CHANGES

2) what remains the same for a considerable amount of time.

3) anything that is special, for whatever reason, as per default context (commonsense).

NOTE - The items in the scene that we talk about (say, John and ball in 'John was dribbling the ball'), (which also includes the subject of the description), are also the "things which remain the same throughout the scene" and hence qualify as "that which remains the same for a considerable amount of time" (type 2). The ball remains a ball throughout, and John remains John throughout the video/scene.

E.g. -

1) John opened the door and stepped outside.

Here the 'changes' are John's action (moving his hand), the door opening, and John stepping outside. Here, this is a short-duration, quick action. So there is no question of anything remaining the same for a considerable amount of time (even though there are things which remain the same in the scene, like say, John's shirt's color).

2) John was sitting quietly for 10 minutes.

Here there are no (apparent) changes. Here, something that remains the same for a considerable amount of time (John remaining quiet for 10 minutes) has been described.

3) John was dribbling the ball.

Dribbling is the change taking place in time and space (of the ball and John's hands). So that's been described. John and ball remain the same throughout the video which makes them being included as the items being talked about. Now, the (basketball) court also remains the same (and which is in the sight/view which contains the reality (John dribbling the ball) being described), but that is not mentioned since that comes under commonsense.

4) In the above examples, we haven't touched upon type 3. If there is a 300 kg man in a scene, he is going to be talked about since he qualifies as type 3 (special in the DEFAULT, commonsense context).
