It seems many is assuming that the CV1 will be able to send the lenses separation value to the PC. I don't see it happening for several reasons. First, they are saying that the sweet spot for the CV1 lenses will be larger. After adjusting the lenses, the user may feel confortable with the setting without the lenses being at their IPD. So, to begin with, adjusting the slider for clarity and visual confort won't be a reliable measure of the user's IPD. Second, the increase in cost and complexity. I don't think it's trivial to put a consumer level electronic lenght sensor which is accurate to sub-mm, that doesn't lose calibration, plus the electronics to digitize the measure, store it and send it to the PC. And third, it would mean that applications, instead of just reading the IPD from the user's profile once, they are forced to interrogate the SDK or declare a callback function just in case the slider has been moved. And the only thing that would change is the virtual cameras separation, because the center of projection and the center of the barrel distortion won't change due to the lenses moving jointly with the displays.
To me the IPD will be set in each user profile. Once selected the correct profile the user will adjust the lenses separation slider until the image is clear and easy for the eyes. I don't see the need for that automatic IPD adjustment.
Has Oculus said anything about this that I've missed? Why so many people is so sure about this?
