Detection is Oblivion's stealth mechanic.  The concept isn't complicated: every actor has a degree of awareness of every other nearby actor, called a ''detection level''.  If this detection level is above a certain threshold then the searching actor (the "detector") is fully aware of the hiding actor (the "target").  The detector can then attack, offer a greeting, report the target's crimes, etc.  If the detection level falls below the threshold again, the detector "loses" the target and can no longer interact with it.

Quite a few factors go into calculating detection levels.  They fall into three basic categories: Sight, Sound, and Sneak Skill.  Sight factors basically describe how well the detector can see the target, and only matter if the detector actually has a direct line-of-sight.  Sound factors measure how much noise the target is making, from movement and from being in combat.  Skill factors measure the ''relative'' sneak skill of the two actors.  In all three cases, the distance from the detector to target plays a very important role.  Whether or not the target has attacked the detector can make an enormous difference as well.
Quite a few variables go into calculating detection levels.  They fall into three basic categories: Sight, Sound, and Sneak Skill.  Sight basically describe how well the detector can see the target, and only matter if the detector actually has a direct line-of-sight.  Sound measures how much noise the target is making, from movement and from being in combat.  Skill measures the ''relative'' sneak skill of the detector & target.  For all three, the distance from the detector to target plays a very important role.  
   
   
The complete list of factors and their values is below.  Note that each factor is given a 'shorthand' name for use in other formulas.  Also note that many of the factors are conditional - they take a "default" value some times and a more complicated value at others. Some formulas even have conditional parts - an extra multiplier or additive bonus that is used only under certain circumstances.  These conditions are given as clearly as possible in the formulas; just be sure to read them carefully.
The complete formula for Detection Level is given below.  Because the formula is so complicated, it is broken into smaller pieces and organized in a table.  Conditional terms are enclosed in square brackets, e.g. "[ + 400, if target is yellow]" means "add 400 if the target is yellow, otherwise ignore this term".
