You're not wrong, but I wasn't speaking using this level of specificity. They also don't look at things continuously for psychological reasons like being bored, sensory reasons like being distracted by something else, physical reasons like having their line of sight blocked, social reasons such as the event ending, or biological reasons like being asleep or deceased. And neither would computers be looking at things continuously, if anything the discontinuity would be even more obvious as computers use "frames" of processing, as well as camera shutter speeds, instead of just being a function of the overall system's response time.
