Human Factors
We made a call to take off from the active runway after someone called 'base leg'; assuming we had sufficient time without causing a traffic conflict; we also had a visual on them. As we were on our roll-out; they requested that the aircraft 'holding short' stop. We continue to take off; and they break off final and sidestep us. We never heard a 'final' radio call or saw them turn final before we made our take-off radio call and took the active runway.
