Sensor location?

Does anyone know the precise location of the IMU inside the Rift body? I need to align the center of rotation with some external sensors.

I suppose I could always open the Rift and measure, but I'd rather not do that unless necessary.

    Behind the display against the panel.

    Is this what you're looking for or have I missed the point? :D

    EDIT: That YT link was supposed to play at 6:40.

    Yes, sort of, though I also need physical units. :)

    Not sure why I didn't think of this first, but iFixit has a teardown image I can use to get relative distances from the edges. I'll convert this to physical dimensions next time I'm in the lab and can measure the case.

    Nice, glad to see you've found a solution. :D

    In case anyone else is interested, here are some measurements using the upper left corner (opposite the cable) as the origin:

    (over, down)
    IMU (53.6%, 27.1%) (91.4mm, 32.3mm)
    Magn (49.3%, 27.1%) (84.1mm, 32.3mm)
    Guesstimate the depth as 4mm from the front cover.

    Assuming a width of 170.5 mm (6.725"), a height of 119mm (4.69"), and lots of rounding errors. :D
