Abstract:
A spatial reference guide for positioning a user at a predetermined location, the guide comprising:a. a planar distal portion, the distal portion defining a first planar outline;b. a proximal portion operatively connected to the distal portion by a web, the proximal portion, the distal portion, and the web having a U-shape when viewed from the side, the proximal portion defining a second planar outline, the proximal portion being relatively closer than the distal portion to the predetermined location along the sight line of the predetermined location, the second planar outline of the proximal portion being sized and positioned directly intermediate the predetermined location and the distal portion such that the distal portion is substantially obscured by the proximal portion when the guide is viewed from a sight line at the predetermined location;wherein an increasing amount of the distal portion is observable as the sight line of a user moves away from the sight line of the predetermined location, andwherein a decreasing amount of the distal portion is observable as the sight line of a user approaches the sight line of the predetermined location.
