User:Tiago Borges Coelho/Unintended computation

Unintended Computation describes computer output that does not follow the original intention of the programmer. These can occur when (physical) conditions change input hardware's normal operation, or when (virtual) programming commands produce erratic outputs. For example, some optical mice when placed on top of a surface with a characteristic reflection move the cursor randomly across the screen even though the mouse itself is motionless. The hardware input (mouse) caused the output (cursor) to behave in a way that was not intended by the manufacturer.
