waved to get my attention

Does it make sense to say "waved" in ths structure of "see, feel, hear +object+ object complement"? It should be "wave" or "waving". I have never seen this kind of wrong structure. Did the writer make a mistake or is he a non-native speaker?

gu70)Adults are much harder to teach how to use computers than children, especially when they're not familiar with computer technology and related terms. At the beginning of one class, I asked the adult students to type "R", "U", "N" on their keyboards to see a program execute. I saw a hand in the back of the room, waved to get my attention....only to find that instead of typing the word RUN, she had written: "ARE YOU IN."

It's an error. It should be "waving" after a comma or "wave" with no comma.

Ems has answered the language point, but it seems to me that the mistake was nothing to do with the student's age. The teacher should have known that there was the possibility of misconstruing both /a:/ and /ju:/ (and, in some parts of the world, /en/ (was the settimg, by any chance, New Zealand?) and so should have said 'Type the letters R-U-N' rather than thinking 'Tee-hee, just the sort of dumb mistake you can expect from these oldies'.
