experience when they were set to a lap suturing task using 2D HD and
a 3D alternative.
"Almost all performance parameters were superior with the conven-
tional glasses-based 3D display compared to the 2D display and the
autostereoscopic display," which did not require glasses to present
depth-perception, the study notes. Participants who wore glasses
sutured faster, more precisely and with more economy of movement,
and even "complained of impaired vision while using the autostereo-
scopic monitor."
And yet, the participants who used a third 3D option — a no-glasses
display custom-built for the study that used mirrors to deliver depth
perception — scored the highest of all and demonstrated how further
research can further the technology of seeing into the surgical site.
