To track the CrystalEyes eyewear in three-dimensional space, an
ultrasound array configured as a triangle of three speakers sits on
top of the monitor. It sends signals along a line of sight to
microphones incorporated in the eyewear. These microphones sample the
transmitted signals 50 times per second.
The triangular ultrasound array and eyewear microphones are connected
to a control unit via flexible cables. The control unit converts
detected phase differences into spatial information, thus tracking the
user's head position and allowing software to rapidly calculate new
perspective views.
The user wearing CrystalEyes VR, that is, the eyewear equipped with
ultrasound microphones, interacts with the image. Additionally, any
number of viewers wearing CrystalEyes stereo eyewear can observe the
first user's interactions.
Since CrystalEyes VR uses ultrasound technology to detect head
position, it will not interfere with devices using infrared, electric
or magnetic fields.

I am a certified diagnostic medical sonographer.
Yes, it is more difficult to visualize the baby's genitalia prior to
16 weeks gestation, I recommend to my patients that I can not see this
area until 20 weeks and after. I also explain to my patients that
ultrasound is not 100% accurate, actually it is only 50% because a
female may have enlarged labia which could mimic a scrotum or a small
scrotum may mimic the labia. You have to understand we are not always
correct, however we are to determine whether the baby has
normal/abnormal anatomical structures. Ultrasound is for diagnostic
purposes which does create a bond between the baby and the family. Ask
the person doing the ultrasound whether or not they are ARDMS
certified in obstetrics-gynecology. The American Registry of
Diagnostic Medical Sonography is the credentialing body for
sonographers.
