These
days
Google
seems
to
have
become
synonymous
with
searching
almost
anything
available
under
the
sun.
May
it
be
the
latest
deals
on
mobile
phones,
the
hottest
gossips
doing
the
rounds
of
the
tinsel
town
and
loads
of
any
technical
or
non-technical
subjects.
We
are
almost
always
getting
bombarded
with
loads
of
information
which
may
or
may
not
provide
the
exact
details
we
are
searching
for.
This
again
prompts
us
to
think
of
ways
to
further
skim
down
the
search
criteria
and
be
more
focused
in
our
approach.
All
said
and
done,
this
helps
us
to
search
out
objects
of
an
intellectual
domain.
i.e,
information
that
could
help
us
in
intellectually
enhance
our
knowledge.
But,
can
an
electronic
device
like
this
can
also
be
used
to
ease
our
tensions
in
locating
physical
objects
that
we
are
sometimes
unable
to
look
for,
but
when
it
is
most
urgent?
For
example,
suppose
when
you
are
about
to
leave
for
an
important
meeting
or
urgent
work,
the
car
keys
go
missing!
You
are unable to trace out where you dropped it last night you came home
after a tiring day at office or even the keys were dislocated
unknowingly by kids at home.
Description:
Let
us now see the importance of this technology by comparing scenarios
in a contrasting era before and after implementing this.
Before:
Suppose
when
you
are
about
to
leave
for
an
important
meeting,
and
the
car
keys
go
missing!
You
are unable to trace out where you dropped it last night you came home
after a tiring day at office or even the keys were dislocated
unknowingly by kids at home.
Honey!
Where
are
the
car
keys???
Err;
I
kept
them
on
the
table
last
night!
I
am
getting
late
for
the
meeting
at
office.
From
the
kitchen:
No
idea
(after
a
pause),
hmmm…
I
faintly
remember
Johnnie
fiddling
with
them
in
the
morning.
Now,
Johnnie
is
a
1
year
old,
unable
to
tell
his
frustrated
dad
about
the
whereabouts
of
the
keys
that
he
had
been
playing
with.
End
of
the
story!
Beginning
of
a
frantic
search
for
the
key
.
.
.
After
adopting
the
Solution:
Logically,
if
we
were
to
place
a
particular
object
in
such
a
way
that
we
would
be
able
to
locate
it
easily,
we
would
most
probably
be
placing
it
in
a
container,
marking
the
container
with
a
label.
The
same
logic
can
be
used
to
find
out
an
article
in
a
room
electronically.
With
the
spread
of
wireless
technologies,
this
is
very
much
possible.
As
some
wireless
technologies
enjoy
the
benefit
of
not
being
bound
by
the
'
line-of-sight
'
requirement
for
detection,
it
makes
it
interesting
to
use
these
technologies
to
sense
the
presence
of
articles
that
are
hidden
from
the
sight
of
the
naked
human
eye.
So,
with this in mind, I proceed to explain the process with an example.
The
main leads in this example would be the following:
(i) Missing
car
key
– [Tagged
CAR
KEY]
(ii) Small
electronic
tag
probably
of
the
like
of
a
ladies’
“Bindi”
-
[The
tag
on
the
CAR
KEY]
(iii)
Wireless
signal
sensing
device,
having
a
range
of
a
few
meters
(or)
enough
to
cover
a
house
diametrically.
– [Wireless
Sensor
on
the
ceiling]
(iv)
Software
with
a
Graphical
User
Interface,
which
would
have
the
layout
of
the
house,
can
be
run
on
a
system
or
be
wall
mounted
[Tagging
Device].
Figure
1: View of the implementation
Now,
the moment one installs this device, the essential pre-requisite to
start using the function would be to mark (or) stick a small
electronic tag on to each of the important articles that you tend to
misplace in your home.
After
sticking
the
tag,
one
needs
to
sync
the
tag
with
the
sensing
device
[indicated
at
(i)
above]
to
index
it
with
the
name
of
the
object,
for
e.g.
the
CAR
KEY.
This
gets
stored
in
a
database
contained
in
the
Tagging
device.
Similarly,
there
would
be
a
number
of
objects,
which
would
be
indexed
into
the
database
after
syncing
with
the
device.
Now
if
we
misplace
this
object
somewhere
in
the
house,
one
just
needs
to
turn
on
the
Human
GUI
software
and
just
search
for
the
indexed
CAR
KEY
object,
the
sensing
device
placed
preferably
at
the
center
of
the
house
would
be
sending
signal
across
the
radii
of
the
house,
and
on
locating
the
tag
placed
on
the
object,
would
be
able
to
display
the
location
on
the
image
layout
of
the
house.
