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....
