"In the early stages of development, Bethesda watched fighting videos to study how people react during melee battles. The team found that most encounters featured more jostling and staggering than was present in past Elder Scrolls titles. Using the Havok Behavior animation system, the team is more accurately mimicking the imbalance prevalent in melee combat by adding staggering affects and camera shake. Don't expect button-mashing marathons where the attacker with a bigger life pool wins the war of attrition. If you're not careful on defense you may get knocked around, losing your balance and leaving yourself exposed for a damaging blow that can turn the tide of the battle. Knowing when to block, when to strike, and when to stand your ground is key to prevailing in combat. "
In hindsight, it's not as clear-cut as I remembered when I read, but this combined with the fact that their combat animation specialist is a boxer/MMA fighter as a hobby tells me that he's the source of their inspiration to make the combat system more dynamic, and therefore, unarmed is the base of that.
