CV1 sensor distance and mounting

I have attached my sensor to a wall about 8 feet from me sitting on a couch and the oculus setup complains that the sensor is not angled properly. If I take a step forward, all works.... But I can't move the wall... Or have my couch a foot away from the other wall..
 
The depth of the room is 11ft 2 inches and the depth of the couch is about 4 feet to the wall, so my seated position is going to be 8feet away horizontally. The standing calibration puts me about 7 feet away.

This seems kinda wrong, and certainly seems like room scale will not work with the current sensors....

     Also tried with the lights out :-)

     I just measured and the distance from my face to the sensor is 5'3"

    Mounting bracket extenders FTW. Now about 53 inches from my face when standing, or 75 inches seated back...and working. When it was further back, tracking was certainly off. You could almost see the VR world pulse slightly almost like the tracker was trying to focus.

    I had a similar experience when trying to do 'room scale', but once touch arrives I'm sure that tracking will be able to use the additional sensor to help pinpoint the depth better so that we won't have to experience the 'focusing' phenomenon.

    That "pulsing" you describe is the Rift switching to it's IMU when the sensor loses you. The Rift can track you without the sensor, but it's much less accurate(and more nausea inducing).

    But generally any time the VR world "Jumps" you've switched from one to the other. Unless you are describing something different.

    Maybe your sensor is mounted too high and it captures mostly the top of your head instead of the front?

    From what I've been able to find out max tracking distance seems to be 2.5 meters (about 8 feet) so room scale will be difficult even with 2 sensors :(

    The sensor is mounted at top-of-door height. If I walk to it, it's about 2 inches above my head... Shouldn't be an issue.

    My bet is new camera(s) for room scale for sure.. Disappointing For a 7x8ft area I am trying to use

    My test right now is the ability to run The Rose and I and be able to walk around the mini planet. In order to do this I have to be in this configuration and seated experiences are just out of range...

    This video says 2 to 5 meters from you. My sensor is less than 2m away and not working... I'm going to open a case

    The best height for the sensor is slightly above your head. For example, at my home setup I have the sensor around 8 inches above my monitor (facing just slightly downwards). This is perfect for seated play, and can accommodate standing as long as I don't walk too close to the sensor. I believe the recommended distance is around 1 meter (or 3 feet) but it can work as close as 1 foot (but with a more limited play space).

    Don't want to hog this thread but since we are talking about sensor placement...

    Perfect place for mine would be about 45 degrees to my left - slightly above my head when sitting (about one metre away from me). Is that a place where I can safely assume everything will work fine or do I need to find an alternative?

    My sensor is about 2 inches above my standing height. @cybereality check the video, it clearly says "at least 2 to 5 meters" and I have a big concern this is not going to go well when we get to order our Oculus touch remotes if it's underperforming so badly.

    @JettStiles I found that it really really wanted to be head-on. The side view worked, or seemed to, but the setup complained it "could not see the front of the rift" hence my setup on the far wall.

    Here's my setup measured to the inch. Seated I am too far from the sensor. If it's any closer I can't walk around the planet in Rose and I. I'm pretty sure my sensor height is close to the touch demo (attached)

    When seated I still seem to be out of range :-(

    Oops: One label is off, the sensor is 5'4" from the couch front, it's not the distance to the wall (bottom label)

    The range is best when the camera is eye-level facing straight forward. However a few inches above facing *just* slightly down does seem to get better performance (especially if you want to use it seated in front of your desk). 2 meters is a lot, the sensor can certainly see the headset when it's closer (though you will have limited lateral range of movement). 1 meter is a good minimum for seated play.
