the word 'perception' has two meaning in wikipedia:
perception is the process of attaining awareness or understanding of sensory information
With microphones, cameras, accelerometers, compasses, temperature gauges, and brightness detectors, smartphones have become extra-sensory devices, able to augment your own perceptions.
cannot perceive it, out of perception.
I think the example 1 take the first meaning and example 2 take the second. why i need to make this difference ? Because my teacher told me that Human perception is limited by the capacity of sense organs. which means we cannot augment perception. And yes, we human being can employ the man-made sensors, but actually it's the man-made sensors perceive the world, not us. they just told us the results, we didn't perceive it, we just know it.
so, I want to know the actually meaning of 'perception'. if perception only means get information from 5 normal sensors of human. then the example 1 is wrong!
