 The <dfn attribute for="XRInputSource">gripSpace</dfn> attribute is an {{XRSpace}} that tracks the pose that should be used to render virtual objects such that they appear to be held in the user's hand. If the user were to hold a straight rod, this {{XRSpace}} places the origin at the centroid of their curled fingers and where the <code>-Z</code> axis points along the length of the rod towards their thumb. The <code>X</code> axis is perpendicular to the back of the hand being described, with back of the users right hand pointing towards <code>+X</code> and the back of the user's left hand pointing towards <code>-X</code>. The <code>Y</code> axis is implied by the relationship between the <code>X</code> and <code>Z</code> axis, with <code>+Y</code> roughly pointing in the direction of the user's arm.
