The present invention refers to a telematic system for management and collection of
data for public opinion polls, market research and the like.
Generalised opinion polls have taken on considerable importance in all sectors. In
recent years there has been an ever-growing demand from public opinion workers to
minimise the time gap between question and answer, between survey and analysis of
the results, especially in surveys like those by telephone, in an attempt to shorten the
interval between an event and evaluation of its impact on the public.
The present invention comes within this context, its purpose being precisely to provide
a telematic system for opinion polls, market research and the like, that minimises
research time, though meeting high quality standards.
Another aim of the invention is to provide such a telematic system that is extremely
reliable, as well as being of extremely simple and economical design.
These aims are achieved by the telematic research system according to the invention
having the characteristics stated in appended independent claim 1.
Advantageous embodiments of the invention emerge from the dependent claims.
Substantially, the invention provides for a structure divided into three specific
positions: a central side (that is the research centre or equivalent body) for
management and processing of the data collected; a peripheral side (that is the subjects
equipped with a terminal, which will be called TOP) to receive the questions and the
resulting replies; a network side (that is the public or private telephone network) for
transfer of information from and to the peripheral user.
The centre side foresees the presence of a computer intended for management of the
peripheral address registry, preparation of messages for sending, handling of
communications from and to peripheral users, data collection and subsequent
processing and printing of the results (including database filing), according to
specially created computerised procedures.
The peripheral side foresees a structure placed with a number x of
families/users/operators, composed of a series of elements - that will be described
below - connected to the normal telephone network whether public (of any country) or
private (irrespective of the body providing the telephone service or the line
characteristics - conventional standard cable, cellular transmission, fibre optics, data
line, etc.).
The network side is represented by any public or private telephone signal transmission
network, irrespective of the body providing the telephone service or the line
characteristics - conventional standard cable, cellular transmission, fibre optics, data
line, etc.
Further characteristics of the invention will be made clearer by the detailed description
that follows, referring to a purely exemplary and therefore non-limiting embodiment
of the invention, illustrated in the appended drawings, in which:
Figure 1 is a diagram showing a general block layout of the remote information survey
system according to the invention, Figure 2 is a schematic view of a terminal or TOP, situated at the user's premises, in
particular:
a) a plan top view of the part of the mobile terminal or TOP; b) a plan view schematically showing, hatched, the inner components of the
mobile TOP; c) a plan top view of the fixed part of the terminal or TOP-BASE, with the main
components hatched, and showing a power supply exploded.
The invention in question will now be described, with reference to the appended
figures, according to the various parts making up a structure of the type: "centre side",
"network side" or peripheral side", indicating for the peripheral side a single entity, in
the currently preferred form.
The "centre side" comprises an advanced computer A, connected to a computer B and
a modem rack C connected to the telephone/data transmission network D ("network
side") of any type present on the market (including satellite, GSM or the like).
To the transmission network D (the conventional public telephone network is the one
currently preferred for optimal distribution) is connected the peripheral side
represented by a certain number x of users (in the preferred case represented by
subscribers to the public telephone network), one exemplary unit of which is indicated
as UT-1 in the reference figure.
The peripheral side comprises the following:
a. a feed-through telephone filter plug E that allows connection by means of a
telephone duplex cable on one side to a normal telephone F - and with any home
facilities such as an answering machine, fax, modem, etc. - and on the other side,
again through a telephone duplex cable, to the component defined as TOP-BASE G; b. TOP-BASE G, that is to say a structure equipped with a circuit board I, a
modem card L for acquisition of the information packages transmitted by the central
side, a battery charging device M to supply the batteries inserted in the mobile or
hand-held TOP charged and blade connectors N for data transfer from and to the hand-held
TOP component. The whole is enclosed in a plastic structure with three possible
connections: one for telephone connection (indicated as LINE and identifiable as a
socket of the plug type), one for possible connection to a telephone in the case of
home installations having a direct line connection of the plug type (indicated as TEL
and identifiable as a socket of the plug type) and one for a network power supply, in
the preferred but non-limiting case, 9 volt, 50 Hz, 600 mA O;
c. the hand-held mobile TOP H, that is to say a structure having a printed circuit P, a buffer battery Q for maintenance of the configuration, a pack of three 1.5 volt
batteries R giving a total of 4.5 volts to supply and illuminate a back-lit liquid crystal
display S with display of a total of 1240 pixels corresponding, in the preferred but
non-limiting version, to 20 columns by 8 lines. The display serves to allow viewing of
the questions and of the answers as they are provide by the user of the peripheral
structure and for exchange of information from and to the central side. The hand-held
mobile TOP is also provided with blade connectors T for data transfer to and from the
TOP-BASE component: the whole is enclosed in a parallelepiped-shaped plastic
structure.
The upper part of the hand-held mobile TOP has a key board with push elements for
the answers to the questions. In the preferred but non-limiting embodiment there are
22 keys, thus divided:
a. five "qualitative" keys U for replies by judgements like "a lot", "fairly",
"little", "not at all" and "no opinion". In the preferred but non-limiting version the
keys are graduated in shades of green from dark (corresponding to the above statement
"a lot") to the palest (corresponding to the above statement "no opinion"); b. ten "numerical" keys V numbered from 1 to 0 of a uniform preferred but non-limiting
blue colour; c. three keys for "dichotomous" answers W of the "yes", "no", "don't know" type
in the preferred by non-limiting version coloured green, red and yellow; d. two scrolling keys X characterised by arrows pointing in opposite directions
for scrolling any texts that do not fit in a single screen view on the display. These
keys, are coloured white in the preferred version; e. two service keys Y for correction and/or confirmation of what is keyed in. One
of these keys is marked "CANC" and the other "INV" and in the preferred version
they are coloured red and green, respectively.
Operation can by summed up as follows, in the preferred but non-limiting
embodiment, with reference to a single unit UT-1:
- the centre side operator sets up the communication and the content of the message to
send to UT-1.
- A first signal, coming from the centre side, alerts the modem contained in the TOP-BASE
to connect to said centre side , thanks to the feed-through telephone filter plug
E that diverts the signal to the TOP-BASE,
- then the peripheral side connects to the centre side, in the preferred but non-limiting
case by easy-way on the Telecom Itapac or similar network for data transfer,
- the centre side thus makes the alphanumeric message available to the UT-1
peripheral side, in the form of a string of characters that can thus be loaded by the
modem structure contained in the TOP-BASE;
- the message thus reaches the premises/residence of UT-1 and transmits data from the
TOP-BASE to the hand-held mobile TOP 4 which are thus translated into graphic
screen displays containing the messages sent;
- at this point UT-1 answers the questions by means of the mobile TOP; and when the
replies have been completed the mobile TOP is placed on the TOP-BASE where the
reverse process begins from the peripheral side to the centre side;
- the modem contained in the TOP-BASE connects with the centre side, in the
preferred by non-limiting case, by easy-way on the Telecom Itapac or similar network
for data transmission and transmits the alphanumeric reply message, in the form of a
string of characters. The centre side structure then transmits the UT-1 data string to the
computer so that it can be processed.
