6. Human
Factors
• Underexplored
– Threats,
risks,
implicaRons
for
designers
• Devise
beSer
soluRons
to
– Ensure
users’
privacy
– Ensure
privacy
of
those
around
wearer
– By
understanding

Devices

16. Right
to
forget
• ‘it
gives
a
record
of
everything
you’ve
done,
day
in
and
day
out,
possibly
even
some
things
you
don’t
want
to
be
reminded
of’

17. LocaRon
disclosure
• ‘…
stalkers
know
where
you
are
at
all
.mes
of
the
day,
know
when
you
go
to
sleep,
riding
a
car,
or
climbing
a
mountain’

18. Discreet
Display
• ‘the
second
screen
will
act
as
sort
of
a
privacy
screen,
keeping
folks
from
reading
your
texts
by
glancing
at
your
wrist’

19. Surveillance
• ‘[wearable
devices
are]
the
NSA's
new
best
friend’

20. Head-­‐Mounted
Displays

21. Speech
Disclosure
• ‘though
you
can’t
mind
people
overhearing
what
you
are
saying’

22. Surrep==ous
Audio
and
Video
Recording
• Social
norms
already
frown
on
making
surrep==ous
audio
recordings
(though
it
isn't
illegal,
it
is
done
only
infrequently
and
with
an
air
of
"secret
agency"
about
it);
video
is
much
more
of
an
intrusion.’

23. Sousveillence
• ‘There's
also
another
challenge
that
affects
not
only
those
who
wear
Glass,
but
everyone
else
around
privacy’

26. Conclusion
• privacy
concerns
are
related
to
type
of
sensors/
data
– Cameras
and
microphones
– GPS
– Displays
• Similar
to
mobile
privacy
concerns
– ExcepRon
:
increasing
invisibility
of
wearables
