I think the senses leg of the canon well fits the "computer peripherals" analogy, and the anticipations leg fit the "operating system" analogy. It's less clear to me where the pleasure /pain fits, possibly as part of the operating system but perhaps more the "applications program" or the electricity or something analogous to the purpose for which the computer and operating system were constructed.
In real life all these three operate very closely together too so it's not like they are entirely separate from each other and this is another area I think DeWitt's ideas are good.
