AUDIO - VIDEO GLOBE
BACKGROUND OF INVENTION
Field of the invention.
The present invention is concerned with interactive educational tools, and
particularly
with an audio-video globe for displaying relevant information stored as pre-
recorded data
associated with a country of choice.
Description of the prior art
It is known to use for educational purposes a model of the earth, supported on
a hexagonal
base. On the six sides of the base, there are as many sectors containing cards
with geographical
information, grouped by continents. This system has the disadvantage of a
cumbersome and impractical management of the data, and requires a lengthy time
to obtain the
desired information. The "Talking Globe", manufactured by Educational Insight
(USA),
uses a sophisticated technology, including a voice synthesizer. The globe
addresses a large
number of questions with a choice of three answers, which can be checked using
keys located on
the support of the globe. The drawbacks of this device are related to the fact
that it
only checks on the user's geographical knowledge without offering any
information. The "Talking
Globe" uses a synthesized voice, and the questions are randomly arranged
without being
efficiently organized. Finally, the information provided is audio, and not
associated with an
image.
There is a need for an interactive educational globe, providing information
and data
related to the geography, history and economics of all countries.

DETAILED DESCRIPTION OF THE DRAWINGS
Figure 1 illustrates a front elevational view of the audio-video globe device
10 according
to the invention. Device 10 comprises an audio-video globe 20 supported on a
pedestal 16.
CA 02251499 1998-11-03
Pedestal 16 is preferably a rectangular box exposing on its upper surface a
front
panel including a fast forward/fast backwards button 12, a play button 13, a
battery box cover 28,
a speaker 30 and microphone 38, and openings 29.
An intermediate barrel shaped member 26 is fixed in an upright position on the
upper
surface of the pedestal 16 at an end remote from buttons 12 or 13, for
supporting globe 20 on
pedestal 16, in the known manner, namely by use of a semicircular support 11
fixed on the
intermediate member 26 at point 36. Globe 20 is mounted on support 11 on two
diametrically
opposed points 23 and 24 (the poles) for ratably positioning globe 20 at the
correct inclination.
Globe 20 includes two hollow hemispheres 21 and 22 preferably corresponding to
the North and
to the South hemispheres. Hemispheres 21 and 22 are separated by an assembly
board 18 along the
Equator. It is to be understood that this specification discloses hemispheres
corresponding to the
geographical ones. However, the hemispheres may be of
unequal surface and separated along another parallel or a meridian, or any
other, crossection in
the globe 20.
The geo-political map of the world is displayed on the exterior of globe 20.
Also attached
to the semicircular support 11 is a LCD display 14.
Figure 2 is a vertical sectional view of the globe 20 combined with a
sectional
horizontal section of the pedestal ~~, s~ow~ng the fuhcti4nal blocks and the
electrical connections
inside the device ~~. A ~~urality p~ sep$ors ~~, ~~,.......,~p ~xp ~pcated ill
tie thickness of the
2o walls of the two hemispheres 21 and 22, underneath the geo-political map of
the world. Assembly
board 18 comprises a decoding matrix 15 for receiving a code from a sensor Sj,
when the sensor
is actuated. To this end, electrical connections 31 are provided
between sensors Sl,...,Sn, and the decoding matrix 15. It is to be understood
that wires 31 may be
directly
CA 02251499 1998-11-03
soldered with an end to a sensor Sj and with the other end to the board 15, or
that the wires 31
may have connectors on both ends for contacting a sensor Sj and a multiple pin
connector
provided on board 18.
Decoding matrix 15 determines which sensor Sj was activated and provides an
identification signal for sensor Sj to a scanner-controller 25, as shown at
32.
A reader 35 is provided inside the pedestal 16 for reading information stored
on a
magnetic media, optic media, or combinations thereof, as intuitively shown at
39. Any kind of
storing means like magnetic tapes, CD-Interactive (CD-I), CD-Audio (CD-A),
voice synthesizer,
can be used for recording data associated with all the countries in the world.
In a preferred
1o embodiment, a Digital VideoDisc (DVD) which can store up to nine hours of
studio quality video
data and mufti-channel surround sound, or 30 hours of CD audio may be used.
Each DVD can
store up to 250,000 frames, which can be hold, still images or full motion
video at 30 frames per
second.
Upon receipt of the identification signal from matrix 15, scanner-controller
25 starts
searching the address of the requested information on the storage medium. The
correspondence
between the address on the storage medium and the location of the sensor is
predetermined
according to the type of media used.
Scanner-controller 25 is connected to reader 35 by a cable 33 which exits
globe 20 at
point 24 and guided inside semicircular support 11 and intermediate support 36
to reader 35
2o mounted in pedestal 16.
LCD monitor 14 receives the selected image information from reader 35, over
cable 34,
which is guided from reader 35 along and inside intermediate support 36.
Preferably, electrical
connections 31 are fiber optics.
A speaker 30 is located inside the pedestal 16 close to openings 29. Power
supply is
CA 02251499 1998-11-03
provided by batteries located under the removable cover 28, or alternatively
through a standard 12
volts AC power pack, I20 or 220 volts input.
The mode of operation of the device 10 is next described in connection, which
Figure 3
shows a block diagram of the device 10 of the invention. To request
information on a country of
interest, the corresponding sensor Sj is activated on the surface of the globe
20. A sharpened
object (pen, stick) may be used to press and activate sensor Sj. Sensor Sj
generates a code signal
which is identified by the decoding matrix 15 and a country identification
signal is generated at
the output of matrix 15. The identification signal is input to the searching
system or scanner-
controller 25. Scanner-controller 25 detects the beginning of any audio-video
recording on the
1o magnetic/optic media 39 corresponding to the identification signal, i. e.
to the designated country,
and instructs reader 35 to play audio-video information previously stored on
39. The information
is reproduced on display 14 and/or by speaker 30. Once display 14 and/or
speaker 30 indicate that
the reader 35 accessed to the address of interest on storage media 39, the
user presses play button
13 for retrieving the information. Button 12 is used in the known manner for
scrolling back and
forth the image and/or sound information.
Optionally, countries name may be stored in memory 17 and can be listed
alphabetically
and displayed on LCD monitor 14, by using fast forward/fast backwards button
12. This feature is
provided for obtaining information on countries difficult to show on the globe
20, such as small
countries like Andorra, San Marino, and Monaco. Thus, a country may be
manually selected by
2o pressing button 12 for advancing or going backward one digit at the time.
The display of the
country name stored in memory 17 is done simultaneously by the access of the
CD tracks, via
skip forward/ reverse button.
A control unit 40 monitors the operation and synchronization of all units.
CA 02251499 1998-11-03
The reader 25 can be also activated through a voice-recognized unit 19. By
using microphone
38, the user can verbally instruct the reader 35 to display the required
information.
Buttons 12 and 13 may also be used to control reader 35 by directly selecting
a country
of interest, using display 14 and /or speaker 30.
In another version, the globe's geopolitical map is printed with conductive
ink that, by a
simple touch can activate any selected country of the globe.
In this way, the conductive ink is at the same time the base of the graphical
representation for
every country and also a sensor (conductive and flexible) generator of
interactivity.
Using the conductive ink will determine a lower price, since it substitutes
the sophisticated
electronic circuits, that would eventually be used in order to determinate the
co-ordinates
of a place on the globe.
As illustrated in Fig 4 and Fig S the world countries are identified by
numbers.
A country number corresponds to one track of CD/DVD, so that it can be
accessed by
punching the respective number on a remote control.
Typically, a CD has 99 tracks for stereo recording. For recording data related
to the 192
countries presently in the world, both left and right channels will be used.
This will
amount to a total of 198 tracks, half of them to be reproduced py tile "left"
channel and
,.
the other half to be reproduced by the "right" channel.
2o Numerous modifications, variations, and adaptations
may be made to the particular embodiments of the invention described above,
without departing
from the scope of the invention as defined in the appended claims.
