1
00:00:04,838 --> 00:00:09,242
Sitting next to me here are what
we call our Solar Stones,

2
00:00:09,242 --> 00:00:13,713
and although we did not
originally create the images

3
00:00:13,713 --> 00:00:17,050
depicted on these tablets,
we replicated them from

4
00:00:17,050 --> 00:00:20,053
ancient petroglyphs down in Chaco Canyon
National Park.

5
00:00:20,053 --> 00:00:23,823
They were created around a thousand years
ago by the Ancestral Pueblo people there.

6
00:00:24,691 --> 00:00:27,560
So this over here

7
00:00:27,560 --> 00:00:30,764
is the final version of our tablet.

8
00:00:31,164 --> 00:00:33,833
And it is a depiction
of what we believe is

9
00:00:33,833 --> 00:00:36,836
a total solar eclipse
around the year 1097.

10
00:00:37,570 --> 00:00:40,173
And the reason we believe that is because

11
00:00:40,173 --> 00:00:43,543
looking at this, it has all the telltale
signs of an eclipse.

12
00:00:43,777 --> 00:00:45,845
It has an occultation in the center

13
00:00:45,845 --> 00:00:48,848
where the moon would be blotting out
the sun, this very circular shape.

14
00:00:49,149 --> 00:00:53,119
It has the solar corona out
and along the sides

15
00:00:53,319 --> 00:00:57,357
and up here on the top is what is believed
to be a reflection of Venus.

16
00:00:57,757 --> 00:00:59,959
While these tablets would be really good
for any learner,

17
00:00:59,959 --> 00:01:02,996
we collaborated with the Colorado
School of the Blind so that

18
00:01:04,064 --> 00:01:04,731
we could make

19
00:01:04,731 --> 00:01:07,867
these tablets accessible to low vision
learners.

20
00:01:08,001 --> 00:01:11,004
Space is typically a very visual field.

21
00:01:11,037 --> 00:01:13,840
You look up at the stars
and you look at pictures of space.

22
00:01:13,840 --> 00:01:18,378
But if you can't see that, then you're
pretty much completely blocked out

23
00:01:18,378 --> 00:01:24,017
from being able to study this and be able
to understand this part of history.

24
00:01:24,184 --> 00:01:28,655
So this way, we have an exhibit
that people can learn from

25
00:01:28,655 --> 00:01:31,658
if they are sighted or not sighted.

26
00:01:32,725 --> 00:01:36,830
It took a lot of time to figure out
how much detail we needed,

27
00:01:36,830 --> 00:01:40,867
how deep the objects needed to be,
what textures we needed to use.

28
00:01:41,301 --> 00:01:43,103
A lot of these things
that we didn't expect

29
00:01:43,103 --> 00:01:46,272
we gained context
through lots of user testing.

30
00:01:46,573 --> 00:01:49,709
So I think this project is really valuable
because it allows people

31
00:01:49,709 --> 00:01:52,345
to interact with space
in a completely different framework.

32
00:01:53,413 --> 00:01:54,547
Every person has

33
00:01:54,547 --> 00:01:57,550
something they can contribute
to the study of space.

34
00:01:57,851 --> 00:02:01,821
And so our hope is that not only can
the blind and low vision community

35
00:02:01,821 --> 00:02:05,125
be included in this part of history,
but that sighted learners

36
00:02:05,125 --> 00:02:09,129
can potentially learn things easier
with a tactile experience.
