ABSTRACT:
An egocentric display that corresponds to a multidimensional frame of reference. The multidimensional frame of reference may include an ego center, a nadir below the ego center, and a zenith above the ego center. The egocentric display includes a center point, an inner concentric circle and an outer concentric circle. The center point represents the nadir. The inner concentric circle is centered about the center point and represents a horizon plane that is perpendicular to a zenith-nadir line that passes through the zenith, the ego center, and the nadir. The outer concentric circle that represents the zenith should have a radius larger that the inner concentric circle and should also be centered about the center point.
