Abstract

Disclosed is a method of showing movement direction in three dimensional virtual reality by using a cursor with four pointer arms to show possible direction. The arms may be highlighted to show the direction that the person is moving in the three dimensional space. When the person moves on an angle, additional directional arms are added.

Cursor Used to Show Navigation and Movement in Three Dimensional Space

      Disclosed is a method of showing movement direction in three
dimensional virtual reality by using a cursor with four pointer arms
to show possible direction.  The arms may be highlighted to show the
direction that the person is moving in the three dimensional space.
When the person moves on an angle, additional directional arms are
added.

      The Figure shows four four-pointer cursors (more are
possible).  This cursor type is used to navigate in three dimensional
space.  When the user moves the cursor up or down, the user moves
forward (toward the top) or backward (toward the bottom) of the
virtual reality.  As the cursor moves in a direction, the arms on the
cursor change color to highlight the direction in which the object is
moving.  For example, if the object is moving off to the exact left,
the left arm is turned red when the object is moved.  If the object
is moved to the upper left, two arms are turned red (the two that
most correspond to the angle of movement).  In this fashion, the
cursor arm color informs the user which angle the object is being
moved in three-dimensional space.

      A three dimensional cursor is represented as three intersecting
axes.  From a two dimensional perspective, the cursor would be
represented as a north/south double headed arrow, an east/west double
headed arrow, and a diagonal double headed arrow to represent the
depth dimension.  The...
