It depends on what is meant by reacts.

I know Griff reacts to Corvo blinking, usually with an exclamation of "Impossible!" (I stole that bit for a chap of mine in one of my fanfics :P)

On House of Pleasure, the two Bottle Street thugs outside the doors of the Distillery (the ones who tell you Slackjaw wants to talk) react if you (meaning Corvo) blink in front of them. They reacted so badly I thought they would draw steel for a sec.

In Lady Boyle's Last Party, several of the nobility also react when you blink (or use Time Stop, or Possession).

It never specifically says what they are reacting to, whether it be your sudden disappearance/reappearance (depending on the circumstances), or the actual visual effects of whatever ability you use.
