The praying mantis is the only invertebrate known to have the ability to see in
three dimensions. So, in the name of science, researchers decided to look into
the elegant insect’s sight a bit further - by fitting test subjects with tiny 3D
glasses.

The team from Newcastle University aims to understand how the bug’s vision
compares to that of humans in the hope of finding clues about how our 3D vision
evolved.




The analysis may also help lead to the development of novel approaches in
implementing 3D recognition and depth perception in computer vision and
robotics, the team said. Making the mantis look like an absolute dude was a
[welcome] consequence.



Dr Jenny Read, from the Institute of Neuroscience at Newcastle University who is
heading up the research said: “Despite their minute brains, mantises are
sophisticated visual hunters which can capture prey with terrifying efficiency.
We can learn a lot by studying how they perceive the world.”



The study has been funded by a £1 million research grant in order to
“characterise the mechanisms of 3D vision in mantises and how these mechanisms
can be applied in science and industry”.



Dr Vivek Nityananda who is part of the team carrying out the research said: “So
much is still waiting to be discovered in this system. If we find that the way
mantises process 3D vision is very different to the way humans do it, then that
could open up all kinds of possibilities to create much simpler algorithms for
programming 3D vision into robots."



A key component of the research is presenting the mantis with virtual 3D
stimuli, such as moving targets which the insects view through world’s tinniest
3D glasses attached by beeswax.

Dr Nityananda explained: “We can do this by fooling them into misjudging depth,
in the same way that our brains are fooled when we watch a 3D movie.”



The experiment will determine if mantis can see the moving object standing out
in depth in a similar way to humans and monkeys, the team said.

This is the first major research project investigating the praying mantises'
site since the Samuel Rossel’s 1983 discovery that the insects have 3D vision.



Mr Rossel came to the conclusion after placing prisms over the mantises’ eyes
and creating an optical illusion that an object was within their range,
prompting them to strike at it.
