You're misreading it, the definition quoted on that page is very broad, specifically a human subject is the following with irrelevant clauses in or's removed and replaced with [or ...]:
> a living individual about whom an investigator (whether professional or student) conducting research:
> - Obtains information [or ...] through [... or] interaction with the individual, and uses, studies, or analyzes the information [or ...]; or
> - [...]
The actual legal definition is here [1], and further clarifies that "interaction" is very broad, specifically "Interaction includes communication [or ...] between investigator and subject."
This clearly qualifies OP as a human subject and this as human subjects research.
