METHOD FOR PERFORMING TRANSACTIONS ON AN APPARATUS, APPARATUS WITH MAN-MACHINE INTERFACE AND DATA CARRIER
The present invention relates generally to a method for performing transactions on an apparatus, an apparatus with a man-machine interface and a data carrier.
The present invention relates in particular to a method for operating a publicly used apparatus, e.g. a fare or fee collection apparatus, that may be operated by means of a graphical communication device such as a flat panel display enhanced with touch screen functionality.
More particularly the present invention relates to an apparatus, e.g. a fare or fee collection apparatus, that may be operated by users, which in view of their abilities and skills strongly deviate from the average user.
BACKGROUND OF THE INVENTION
Fare collection apparatuses are an important element of public transportation networks allowing users to select and purchase services without support of employees of the transportation organisation.
In railway or bus stations, passengers normally appear in bursts, e.g. before a train or bus leaves, so that it is important, that time spent for transactions performed on fare collection apparatuses is kept as low as possible for each passenger.
An important part of the whole transaction leading to the emission of a travel ticket is the concrete collection of the fare. For this part of the transaction various solutions have been provided. The user may either pay in cash or by credit
card such as a magnetic stripe card, a chip- or IC-card as described in [1], U.S. Patent 6,142,381.
With publicly used fare collection apparatuses, a major part of the transaction time is however used for the man-machine interaction.
Fare collection apparatuses are therefore designed to allow users with average skills and knowledge to conveniently perform transactions in a minimum of time. For non-average users the fare collection system may provide additional support. E.g., the menu provided on the screen of a display unit may allow a user for example to select a desired language. However additional information on the screen may then be confusing for other user so that the resulting solution, i.e. the implemented man-machine interface, will be a compromise that does not allow to reduce the over all transaction time to a minimum. Additional menu steps for example may unnecessarily prolong the transaction time for users which do not require the offered options .
For handicapped users, e.g. users with impaired vision, fare collection apparatuses may even be impossible to handle, so that the use of these systems is avoided or support from personnel of the transportation organisation is required whenever a transaction shall be executed.
It would therefore be desirable to provide method for performing transactions on an apparatus and an apparatus that allow users, in particular users with abilities, skills or knowledge deviating from those of the average user, to perform transactions on said apparatus in a minimum of time.
SUMMARY OF THE INVENTION
The above and other objects of the present invention are achieved by a method, an apparatus and a data carrier according to claim 1, claim 7, and claim 12 respectively.
The inventive method allows to perform transactions on a publicly used apparatus that comprises a man-machine interface capable of reading data from a data carrier belonging to a user of said apparatus. According to the present invention user specific data are transferred from the data carrier to the control unit of the apparatus, which, based on said user specific data, individually configures the man-machine interface before a transaction by the concerned user is performed by man-machine interaction.
The user specific data may be stored in or on a bar-code card, a magnetic stripe card, a contact or contactless IC-card or a passive or active transponder, operating by means of radio frequencies or induction, such as a SAW (surface acoustic wave) -device.
The apparatus will therefore, after insertion of the data carrier or after contactless transfer of the user specific data, automatically be configured according to the configuration data stored on said data carrier or in a centralised database.
The input output devices and/or the media provided for the man- machine interaction are therefore adapted to the individual requirements of the users.
According to the read or downloaded set of configuration data the control unit adapts the language applied on the man-machine interface, the menus and input fields displayed on the screen of the display unit, the layout, in particular colours character fonts and/or field sizes, displayed on the screen, the sound, spoken instructions and information or control
signals, in particular loudness of the sound, soft key functions and/or print outs such as travel tickets.
The user will therefore always find the apparatus in a known personal configuration, preferably only with the objects and media required for his usual transactions. Hence, every user, handicapped users, tourists, children and users with average skills and knowledge can perform transactions on said apparatus in a minimum of time.
The inventive solution is especially helpful for users with physical or mental abilities deviating from those of the average user.
E.g., users with impaired vision will be familiar with their individually configured layout on the screen of the display unit and with the loudness of spoken information. Input and display fields on the screen will be adapted according to their individual requirements. Colours which lead to a poor intelligibility of the screen content and layout may be avoided as well as input fields that can not be handled. Hence, for handicapped users the advantages of the inventive solution are threefold. The user is familiar with the required details of the man-machine interface, in particular the graphical layout. Only those objects are displayed which are required by the user so that confusions regarding superfluous options are avoided. Hence more space is available to increase the size of the fields which are actually required for the transaction.
If the display unit is enhanced with touch screen functionality, the user can make his selections on the screen. If the man-machine interface comprises keys of a keyboard with changing functions, the related information can be displayed on the screen with a pre-selected layout.
The inventive solution may also help tourists, speaking another language, or children to perform transactions on the apparatus
in a minimum of time. The language applied on the man-machine interface will be selected as required.
To facilitate handling of the apparatus, the configuration data may contain only a limited number of destination codes. Instead of hundreds of destinations available, the man-machine interface may only display a reduced set on the screen from which the user will select. Travel class and validity, one way ore return, may already be pre-configured. Input settings for the transactions may therefore be pre-configured so that only deviations from a standard must be entered.
The user specific data stored on the data carrier may contain a complete set of configuration data or only a code unambiguously identifying the user so that the related set of configuration data can be downloaded from a centralised storage device. In case that a user frequently uses an inventive apparatus his personal configuration data may be stored locally in the apparatus .
The user specific data are stored in or on the data carrier and/or in the centralised storage device during a session, when the optimal configuration parameters for the user are selected by means of
a) an inventive apparatus
b) a centralised system of the system administration or
c) an institution's or the user's personal computer device, which can be connected preferably via Internet to the centralised system, from which at least parts of the man- machine interface can be downloaded for evaluation purposes.
The man-machine interface of the inventive apparatus comprises a reader module that is capable of reading data from a data carrier, a display unit, preferably a flat panel display
enhanced with touch screen functionality, a sound module with a loudspeaker used for acoustically issuing signals and information and/or a printer device.
A data carrier used to store individual configuration data may be a bar-code card, a magnetic stripe card, a contact or contactless IC-card and/or an active or passive transponder operating by means of induction or radio frequencies such as a module operating with surface acoustic waves.
Said data carrier may also be used as a credit card, a personal identification card or even as a travel ticket. In a preferred embodiment of the invention the apparatus may be capable to write data onto the data carrier either to change the set of configuration data or to store ticket related data.
In case that no data carrier is used the apparatus and the an- machine interface may operate in a standard configuration.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Figure 1 shows an apparatus 20 equipped with an inventive man- machine interface that comprises a display unit 1 enhanced with touch screen functionality and a sound module 2 with a loudspeaker.
The display unit 1 is for example a touch sensitive LCD flat panel display as described in [2], U.S. Patent No. 5,777,596, which allows a user to provide input into a computer device by simply touching an LCD display screen with a passive device, such as a finger, stylus, or a ball point pen.
The apparatus 20 further comprises, as shown in figure 4, a memory module 9 connected to a control unit 10 that is designed
to configure and control the man-machine-interface, that is used to perform transactions available on the apparatus 20.
Since the apparatus 20, in this preferred embodiment, is used for automated fare collection, it further comprises a printer unit 3 capable of printing travel tickets, a cash collection unit 4 and card reader 5 which is used to read user specific data from an inserted data carrier, i.e., a bar-code card, a magnetic stripe card, a contact or contactless IC-card and/or an active or passive transponder operating by means of induction or radio frequencies such as a module operating with surface acoustic waves. The apparatus 20 of figure 1, which in this embodiment is fully equipped, further comprises an input device 6 such as a keyboard, a radio frequency unit 7 designed to exchange data with radio frequency transponders carried by the users, and an interface module 8 which connects the apparatus 20 to a centralised management system 11, 12 (see figure 5) .
Figure 2 shows a data carrier 31 in the form of a credit card or personal identity card comprising a bar-code 33 and (for illustration purposes) a magnetic stripe 34.
A reader device for bar-coded cards is described in [3}, International Publication WO 02/13130 Al . A reader device for magnet stripe cards is described in [4}, U.S. Patent 5,061,842.
Figure 3 shows a contactless IC card 32 with an integrated circuit 35 and an antenna 36, i.e. an inductive transponder, from which the card reader 5 or the radio frequency unit 7 can read data.
In a preferred embodiment the card reader 5 or the radio frequency unit 7 may also be designed to write data onto the data carriers 31, 32.
Transponder technologies are known from [5], International Publication WO 00/30028, [6], U.S. Patent 6,025,784 and [7], U.S. Patent Application Publication US 2002/0002534 Al .
The transponder described in [5], which allows the identification of card holders, comprises an integrated circuit (IC) connected to an antenna. This transponder may be integrated in a special housing or on a contactless IC card as described in [1] and shown in figure 3.
As described in [6] , transponders are also used for remote identification of vehicles, allowing to automatically assess charges against the owners of passing vehicles, and then bill the owners digitally. This enables persons to pay tolls without having to slow down at the toll booths to interact with an apparatus and to deposit currency. An automated transaction management system allowing the managing and processing of these transactions between multiple users and collection systems without man-machine interaction is described in [7] .
If no data carrier is used, then the apparatus 20 with its man- machine interface may operate in a standard configuration, e.g. in a first mode.
When a user approaches an inventive apparatus 20 with a transponder 32 or inserts its data carrier 31 into the card reader 5, then user specific data are transferred from the radio frequency unit 7 or from the card reader 5 to the control unit 10. The user data may contain a set of configuration data or only a code that unambiguously identifies the card holder. Based on that identification code the control unit 10 will read or download a corresponding set of configuration data from a local or centralised storage device 9, 11 (see figure 5) .
Figure 5 shows inventive apparatuses 20 connected over the Internet to a network management system (NMS) comprising a server 11 and a terminal 12. Program updates, e.g. changes of
destinations, travel fares and travel information, may therefore be transferred from the server 11 to the apparatuses 20 over the connecting network. The server 11 may also be used as the centralised storage device from which the apparatuses 20 can download user related configuration data.
Based on the received configuration data the control unit 10 individually configures the man-machine interface before a transaction by the card holder is performed by means of man- machine interaction. The input output devices 1, 2, 3 and the media provided for the man-machine interaction are therefore configured and adapted according to the individual requirements of the users.
As shown in figures 6 to 8 the control unit 10 may adapt the language applied on the man-machine interface, the menus and input fields 1-11A, ..., 1-31A displayed on the screen 1-1, 1-2, 1-3 of the display unit 1, the layout, in particular colours character fonts and/or field sizes, displayed on the screen 1- 1, 1-2, 1-3, the sound, spoken instructions and information or control signals, in particular loudness of the sound, soft key functions and/or print outs such as travel tickets according to the configuration data.
The configuration of an apparatus 20 may be done in various ways. Figures 6 to 8 show different examples of the layout of the screen 1-1, 1-2, 1-3 of the display unit 1 which is enhanced with touch screen functionality.
On the screen layout of figure 6 the user has configured the man-machine interface to accept character entries. The layout is partitioned in two section 1-11 and 1-12. In the first section 1-11 the user may select one of the categories CLASS, ROUTE and DESTINATION. In the second section 1-12 is a keyboard with character fields provided, that allows the entry of characters to select a destination.
The layout on the screen 1-2 shown in figure 7 comprises a numerical keyboard that allows the entry of a code for the desired destination.
The layout on the screen 1-3 shown in figure 8 comprises a scroll field 1-3A which allows to scroll through the available destinations .
The user may therefore chose one of the available layouts. Further the user may configure the language applied on the man- machine interface, the menus and input fields, the layout, in particular colours character fonts and/or field sizes, displayed on the screen, the sound, spoken instructions and information or control signals, in particular loudness of the sound, soft key functions and/or print outs such as travel tickets according to his or her requirements.
A suitable configuration may be found and stored on the data carrier 31, 32 or the server 11 in different ways. A user may find a suitable configuration directly on an apparatus 20. In a preferred embodiment of the invention trial versions of the screen layouts may be downloaded from the server 11 over the connecting network, e.g. the Internet to the personal computer of the user. The user may therefore conveniently select a configuration at home and send the obtained configuration data to the server 11 of the network management system. Network administration may then store the configuration data on a data carrier 31, 32.
Data carriers 31, 32 may also be programmed by a travel agency that makes travel arrangements for foreign tourists. Upon arrival, the tourists may receive bar-coded cards 31 or transponders 32 containing the required configuration data.
The users will therefore always find the apparatus 20 in a known personal configuration, preferably only with the objects and media required for his transactions.
The inventive solution is especially helpful for users with impaired vision. Input and display fields 1-11A, ..., 1-31A on the screen 1-1, 1-2, 1-3 will be adapted according to their individual requirements. Colours which lead to a poor intelligibility of the screen content and layout may be avoided as well as input fields that can not be handled. For handicapped users the advantages of the inventive solution are threefold. The user is familiar with the details of the man- machine interface, in particular the graphical layout. Only those objects are displayed which are required by the user so that confusions regarding superfluous options are avoided. Hence more space is available to increase the size of the fields which are actually required for the transactions.
The data carrier 31, 32 may also be used as a credit card, a personal identification card or even as a travel ticket. In a preferred embodiment of the invention the apparatus 20 may be capable to write data onto the data carrier 32 either to change the set of configuration data or to store ticket related data.
