Sensor dependent content position in head worn computing

A head-worn computer, comprising:

• a see-through display adapted to present content to an eye of a user wearing the head-worn computer and adapted to provide the user with a see-through view of an environment proximate the user;
• and
• a processor adapted to present the content within a display field of view of the see-through display based on (1) a forward movement vector of the head-worn computer indicative of a forward movement speed and direction of the user, and (2) a sight vector indicative of the direction the user is facing,
• the processor further adapted to present the content such that (1) it appears in the display field of view when the forward movement speed is below a predetermined threshold, (2) it is not presented in the display field of view when the user is looking generally straight ahead and the forward movement speed is above the predetermined threshold, and (3) it is presented in the display field of view when the user is looking to the side of the forward movement vector and the forward movement speed is above the predetermined threshold.
