A computer system enhances guidance information on a display, allowing a user position and orientation in 3D space to be achieved. In some embodiments, the guidance is visual, for example the blurring of display objects not at the desired position. In some embodiments, the guidance is aural, for example placing a sound moving to the desired position. In some embodiments, the guidance is tactile, for example using haptic pads attached to a head-mounted display to push the user in a specified direction. The system may be used to guide the user spatially for the performing of a task, to help the user avoid sensitive components, or to guide the user to position a sensor, such as a camera, in an optimal direction for taking measurements. The system includes head positioning, hand positioning and gaze positioning techniques.
