If a woman touches your arm. Does it mean interest?

Anonymous
I introduced myself to this girl and she lightly touched my arm while I was talking to her. the next time I seen her she said hi to me smiled and waved. I saw her looking at me later on and I looked back up and we made eye contact and she gave a small laugh smiled and wave again. One time before I introduced myself to her my friend was with me and he told me she looked me up and down when I wasn't looking. Is she interested?
