1. A vestibulo-ocular performance measuring device wherein:

  • the device is configured for measuring a human physiologic vestibulo-ocular performance characteristic selected from the group of;

    vestibulo-ocular reflex;

    dynamic visual acuity;

    dynamic visual stability;

    kinetic visual acuity;

    retinal image stability; and

    foveal fixation stability; and

    the device comprises;

    an eye orientation sensor wherein;

    the eye orientation sensor is attachable to a person'"'"'s head;

    the eye orientation sensor comprises a video camera; and

    the eye orientation sensor senses vertical movement and horizontal movement of at least one eye;

    a head orientation sensor wherein;

    the head orientation sensor is attachable to the person'"'"'s head;

    the head orientation sensor senses pitch and yaw of the person'"'"'s head wherein pitch represents a rotation about a first axis representing up and down movement of the person'"'"'s face when the rear of the person'"'"'s head moves in the opposite direction and yaw represents horizontal movement of the face when looked at from the front about a second axis substantially aligned with the spine and perpendicular to the first axis; and

    the head orientation sensor senses pitch and yaw in a range of frequencies between 0.01 Hertz and 15 Hertz;

    the head orientation sensor comprises a micro-electro-mechanical system integrated circuit comprising a module selected from the group consisting of an accelerometer, a magnetometer, and a gyroscope;

    an electronic circuit wherein;

    the electronic circuit comprises a battery, a central processing unit, and a memory unit;

    the electronic circuit is responsive to horizontal and vertical eye movement information received from the eye orientation sensor;

    the electronic circuit is responsive to pitch and yaw information received from the head orientation sensor;

    the electronic circuit uses a Fourier transform to generate a vertical gain signal and a vertical phase signal in response to the vertical eye movement information and the pitch information; and

    the electronic circuit uses a Fourier transform to generate a horizontal gain signal and a horizontal phase signal in response to the horizontal eye movement information and the yaw information; and

    a display wherein;

    the display is attachable to the person'"'"'s head.
