As suggested in the previous post, I think of a cognitive system as an information system. In this post, I want to look at a particular information system, namely a video camera.
Let me be very clear here. I do not think that a cognitive system is very much like a video camera. Rather, I see them as very different. However, by looking at a video camera, we can examine some basic principles that seem to be common to all information systems, including human cognitive systems.
In particular, we want to look at:
- the input phase, where data is gathered;
- the organization phase, where the data is assembled together;
- the output stream — the final output information.
The input phase
For the video camera, the data is gathered into a pixel map. I am going to describe this as categorization. That might seem a strange term to use for generating a pixel map, so I should first explain why I am using that term.
