As long as u are happy with only beeing able to look up/down and Left/right
( x and y axis) u can use the standard mouse tracker utility which comes with the Track Ir software.You willll still need the mouse from time to time
,then you just have to keep your head in one position. 6DOF (leaning to the side and back/forward,up/down..) in SH5 is not possible and not necessary i think.
