Crossing the boundary - analogue universe, digital worlds

2.6 Going back

Capturing bits of reality and transferring them to a computer would be a pointless exercise if they stayed locked in the digital world. We want access to what we've captured. We want to see the results. In particular, we may want to look at our captive in a different form. For instance, suppose we input the series of temperature readings shown in Figure 2a into a computer. A useful way of looking at these numbers would be in the form of a graph or chart similar to that shown in Figure 2 (b). All this means that at some point we will have to take our digital slice of reality back across the boundary into the analogue world where we can look at it and play with it.

In I look in a bit more detail at what it means to go back across the boundary, and the sorts of device that are commonly used in the process.
