It's true that we are not always conscious of a sense of identity, but that
analogy would be representing visual information in a simulation. There is
no need to simulate what is going on behind a person's back as long as any
shadows or reflections affecting his visual field are taken care of. Of
course, the simulation must instantly create the new visual information when
the person turns his head, and similarly it must provide information
pertaining to memory and personal identity if he should decide to focus on
this.

If I started experiencing your thoughts, then I would be you. It would be
like a duplication experiment in which you can expect an equal probability
of finding yourself in your original position or in my position. While this
was happening, I (Stathis) would be unconscious. After it was over, if I
were left with no memory of the event, I might notice a discontinuity in the
external world, things apparently having moved substantial distances
instantaneously etc., but it wouldn't affect my sense of identity.

Computationalism implies that a stream of consciousness survives
fragmentation of the process generating the stream. If it did not, then
there would be some change in experience as a result of fragmentation. For
example, if an experience supervenes on past computational states as well as
on the present instantaneous state, then arbitrarily slicing up the
computation will change and perhaps completely disrupt the stream of
consciousness. Consider a time interval t1t2t3 in which a simulated subject
perceives a light stimulus (t1, t2, t3 are according to the clock within the
simulation). The light is shone into his eyes at t1, and he presses a button
at t3 to indicate that he has seen it. Now, suppose that the computation is
cut at t2, so that the interval t1t2 is run several real time days before
t2t3, or several days after, or not at all. Then since the experience during
t2t3 is dependent not only on the computational activity going on in that
interval, but also on what has gone on before, perhaps by excising t1t2 from
its normal position in relation to t2t3 the subject will not perceive the
stimulus, or not perceive it in time to press the button at t3. But that
would mean the same computation (and same physical activity in a computer)
in t2t3 would in one case result in the subject pressing the button and in
the other case not; moreover, this could be a third person observable effect
on the screen. Hence, the only reasonable way to look at it is to say that
consciousness supervenes on the instantaneous computational state (or more
simply, consciousness *is* the computational state), which makes it
impossible to know from the inside whether your computation has been
fragmented.
