1. A method, comprising: generating, by a processor, a world space, the world space being substantially bound by a portion of a physical world environment relative to a head mounted display, wherein: translational movement of the world space substantially corresponds to translational movement by the head mounted display from a first point in space to a second point in space, and rotational movement of the world space substantially corresponds to rotational movement by the head mounted display where the head mounted display remains at the first point in space and rotates about an axis; generating, by the processor, a sphere space, the sphere space being a finite area substantially surrounding the head mounted display; translational movement of the sphere space corresponds to the translational movement by the head mounted display from the first point in space to the second point in space; rotational movement of the sphere space substantially corresponds to the rotational movement by the head mounted display where the head mounted display remains at the first point in space and rotates about the axis; generating, by the processor, a display space, the display space being a finite plane disposed in front of the head mounted display; translational movement of the display space does not correspond to the translational movement of the head mounted display from the first point in space to the second point in space; rotational movement of the display space does not correspond to the rotational movement of the head mounted display where the head mounted display remains at the first point in space and rotates about the axis; receiving, from a sensor, a first constructive translational movement input representative of a non-translational movement of a body of a user where the body of the user does not move from the first point in space to the second point in space and the non-translational movement mimics a movement of the body of the user translationally moving in the world space; executing, by the processor, a first translational instruction associated with the first constructive translational movement input, wherein the first translational instruction comprises the moving the body of the user a first distance that corresponds with an actual movement of the body of the user from the first point in space to the second point in space in the world space relative to the head mounted display; and sensing, by the sensor, a presence of the world space resizing stimulus, the world space resizing stimulus indicating an amount to reduce a size of the world space relative to the head mounted display; executing, by the processor, a world space resizing instruction to reduce the size of the world space by the amount indicated by the world space resizing stimulus; receiving, from the sensor, a second constructive translational movement input; and executing, by the processor, a second translational instruction associated with the second constructive translational movement input, wherein the second translational instruction comprises the moving the body of the user a second distance that corresponds with an actual movement of the body of the user from the first point in space to the second point in space in the reduced-size world space.
