Human Factors
The First Officer was flying the aircraft and we were cleared for the visual; backed up with the RNAV (GPS) Runway XXR. Tower requested us to slow to our slowest practical airspeed for traffic landing in front of us on the crossing runway. Knowing that we also had traffic following us on our runway; I anticipated that we would need to exit quickly once we landed. We had previously briefed to exit the runway at T; but upon landing I took control of the aircraft earlier than usual when Tower requested that we exit sooner than planned at N. I slowed the aircraft using manual brakes at a quicker rate than normal; and once we were at a safe taxi speed I started to turn off the runway but was not able to complete the turn because the tiller wheel jammed up. I had to stop the aircraft thinking we might have a Nose Wheel Steering problem; which left us partially on the runway. I had the First Officer immediately report that we were having trouble exiting the runway. Without hesitation; Tower sent the aircraft following us on a go around and asked if we needed assistance. But I then had a chance to assess the situation and realized that due to the rapid deceleration rate; my black sunglass case had slid forward and got jammed underneath the tiller wheel arm preventing it from rotating any further. So we advised Tower we had control of the nose wheel steering and that we did not need any further assistance.This situation could have been prevented had I secured any loose items; but it was a lesson well learned. We did take appropriate action advising Tower immediately and stopping the aircraft to prevent any excursion from the taxiway. The other aircraft was not in conflict since Tower had them go around.
