Position wearable optics unit on participant
If desired, use the provided belt to fasten the
ETVision
Controller to the participant’s waist.
Alternately, have the participant hold the Controller in some other way, or support the Controller on a
surface near the participant. Assuming indoor use, it is usually not necessary to use the optional
filtered visor, but the visor may be used if desired. (See section 7 for outdoor use).
Have the participant put on the optics frame just as they would a pair of eyeglasses. If the participant
is wearing prescription eyeglasses, the
ETVision
frame can simply be worn over the glasses as shown
in one of the photos below.
When the subject is wearing the
ETVision
frame, the top of frame should be just above the eyebrows.
If the person is wearing prescription eyeglasses, the bottom of the
ETVision
frame should be near the
bottom of the eyeglasses frame. An image of the left and right eye should appear in the
Left Eye
and
Right Eye
windows, on the
ETVision
application. When the subject is looking more or less straight
ahead, the iris and pupil of each eye should be more or less centered vertically in the window
(although it need not be “precisely” centered). Correct positioning is shown in the photos and screen
shots below.
