Human Factors
I was inbound from the southwest. At 6 miles out I made my initial call on CTAF frequency stating that I was 6 miles southwest; inbound. There were no other transmission on CTAF so I chose to setup for a right base entry for runway XX. My second radio call stated my location using a common visual reference near the airport. I said I'll be entering the right base for runway XX. Descending into the right base on the visual approach and I scanned the area for traffic as well as the airport environment. I saw no other aircraft and there were no other transmissions. I stated I was on the right base for Runway XX; full stop. As soon as I turned final; which was about a 1/2 mile final; I announced over CTAF that I was on final for Runway XX; full stop. My touchdown for landing was about 600 ft beyond the numbers. As soon as I touched down I saw another aircraft on the runway; opposite direction; about halfway down the runway. I applied maximum braking and slowly started veering to the left as I thought if he didn't rotate in time I would have to go off the runway and into the grass to avoid him. I recognized that he began doing the same thing so it seemed that we both saw each other and were both going to the left. When I first saw him I immediately recognized that he was a high wing airplane so with me being a low wing I knew we don't need to completely clear each other horizontally. We passed each other on the left with his right wing clearing above my right wing. I could see well prior to passing him that our wings would not strike. After passing him I asked over CTAF if he had made any radio calls. A local resident who was watching had a handheld radio and he transmitted that he never heard any radio calls from the Cessna. After clearing the runway the Cessna made his first transmission that he was taxiing back on runway YY. I asked if he could offer an explanation and he apologized and said that they had entered the wrong frequency. I said I understood and at least nobody got hurt. He replied and apologized again and said they were making calls but they were just on the wrong frequency.After I parked my airplane the local resident came over and explained to me that the Cessna wasn't taking off but that he was actually landing; so we both landed at the same time. I don't recall him having a landing light on so he was difficult to see even on the runway. My landing light was on and the witness said my aircraft was very visible due to the light.I considered a go around when I saw him but I decided to apply max braking instead for two reasons. One; I was immediately under the impression the Cessna was taking off; not landing. If that was the case I was expecting him to be rotating at any second. I did not want to climb into his path if that was going to be the case. Secondly; I knew that if I absolutely had to I could go into the grass to clear the runway. Either way I felt more in control on the ground whether it be on the runway or in the grass.
