Abstract

The method involves touching locally limited surfaces of an input field in a specific sequence, where an appearance of the input field is standardized during input of a code. A marking provided in the input field deviates from border characteristics of the surfaces of the input field. An advertisement logo is displayed in a screen (6) when the code is input in the input field that is arranged in a place accessible by the public. Independent claims are also included for the following: (1) a vending machine with an input field (2) a computer program for controlling a touch sensitive display.

Description

The The invention relates to a method for entering a code via a touch-sensitive Input box.

touch-sensitive Input fields are known in particular from computer technology. For example, touch-sensitive surfaces as so-called "Touch Pads "to control the Mouse pointer used on a screen. These surfaces have any color and determine based on the electrical conductivity the place of touch with a finger or a pen.

It are also touch-sensitive Input fields are known, which are designed as screens. These Input fields are "Touch Called "screen". These are also electrically conductive surfaces, with where the point of contact a pen or a finger can be determined. Behind this surfaces are screens, such as CRT screens or TFT screens, arranged. The touch the surface the screens depending on the software program, a change in the graphic playback on the screen surface. Such touch screens are for example at ATMs, ticket machines or other devices, the public to disposal be used.

at some touch-sensitive Input fields must be before the input of information or control commands are checked, whether the user is authorized to do so. For example, ask the touch-sensitive Screens of cash dispensers from a secret number with the Data of a magnetic stripe card are compared. The secret number is the user's authentication code (authorization code).

The Query of the code occurs only when the user a magnetic stripe card inserted into the cash dispenser. For other devices that lower security requirements and no magnetic stripe cards Use will be at touch of the input field in principle the input of an authentication code requested or at a short touch the screen displays a representation that is required to enter a Prompt codes.

at Entering the code will determine localized areas on the screen Associated with characters (e.g., letters or numbers). These can either permanently marked on the input field or on a touch screen be marked by a screen display. The user remembers a character code (e.g., numeric code) and touches in the sequence of the code those surfaces, up which the corresponding numbers are shown.

disadvantage such input method in public accessible devices is the fact that often not authorized persons try by entering any code to activate the input device. These input attempts may be too a wear or damage of the input field. There is also the danger that unauthorized Persons at random or due to the observation of an authorized person the correct code enter and thus gain access to the system.

task The present invention is a method for input a code over a touch-sensitive Input field to create which unauthorized persons of it discourages any code over to enter the input field.

These The object is achieved by the Characteristics of claim 1 solved.

at Entering a code where localized areas of the Input field are touched in a certain order, will be during the Input the appearance of the input field kept uniform or Alternatively, provided with a pattern that depends on the course of the Borders of the local limited areas differs.

With in other words, a representation can be selected on the input field, which in no way suggests that the input field for acceptance an input code is in standby. If an unauthorized Person touches the input field, without entering the correct code, there will be no response the input field or any other part of the device that the input field is assigned, caused.

By the static or neutral appearance of the input field is not Causes unauthorized persons to to touch the input field, to enter a code.

Even if an unauthorized person observes how an authorized person inputs a code by systematically touching the input field and thereby activates the device associated with the input field, he will hardly succeed in repeating the code input. Since the unauthorized person does not recognize any input fields on the input field Neither will it be able to remember the system of touching the input field and to repeat it in order to enter the code.

A alternative embodiment The invention is characterized by the features of claim 2. Here is the over a touch-sensitive Input field enterable code from a certain rhythm. For example, similar to the Morse code long touches and short touches alternate in given patterns. Again, the input field until the completion of a complete Code entry kept neutral or provided with a picture, which has no relation to the code input.

Of course, both can different methods are combined, i.e. that localized surfaces, which are not recognizable on the input field, in a certain rhythm touched Need to become, to a complete Play code.

As mentioned, is the touch-sensitive Input field preferably a screen. It can also be a matter of course Input field without screen function can be used for code entry.

During the Input can display a static advertising logo on the screen be until the complete Code is entered. Naturally is any other, not related to the code input Display possible, especially a movie ad.

As mentioned, the method is particularly advantageous if the touch-sensitive input field at a public accessible Place is arranged. Here is the greatest danger of actuation of the Input field by an unauthorized person. Consequently, the inventive method the biggest advantage here.

The This invention is particularly intended for use in conjunction with a Vending machines proposed which are arranged in a sales room is. For example, you can automatic baking stations, which are set up in supermarkets, one touch-sensitive Have screen (touch screen), the input of baking orders or other control commands. This input may of course only by authorized sales personnel. For this Reason will be on the screen either no representation or the Presentation of a logo of the supermarket in which the machine is set up is shown until the correct code is entered. As soon as the correct code is entered, sets a running background Computer program a common input mask with various input fields, the touch of the Screen at a location associated with an input field, is interpreted by the computer program as data input and the machine is controlled according to the input. Of course you can the touch screen is also associated with other input means (e.g., buttons) become. These input means are activated only when over the Input field the correct code was entered.

The The invention also relates to a machine with a touch-sensitive Input field for entering a code.

Also with respect to the machine, it is an object of the invention, an input field to create which unauthorized persons from the operation of the input field keeps.

These The object is solved by the features of claim 8.

There while the input is the appearance of the input field is uniform or is provided with a pattern which has no relation to certain input surfaces, an unauthorized person does not associate the possibility of entering a code with the representation on the input field. He is consequently influenced by the operation of the Input field held.

In turn if the input field is preferably a touch-sensitive screen, on the to complete Code entry a logo, a photo or a movie sequence can be.

Of the Automat is preferably located on a publicly accessible Place like a sales room.

• – Festlegen örtlich begrenzter Flächen des Eingabefeldes für die Eingabe eines Codes über den Bildschirm,
• – Festlegen einer bestimmten Reihenfolge und/oder eines bestimmten Rhythmus der Berührung der begrenzten Flächen des Bildschirms als Code zur Aktivierung einer Dateneingabe.

Finally, the invention is directed to a computer program for controlling a touch-sensitive screen. The computer program has sections of code that do the following when run on a computer:

• - defining localized areas of the input field for entering a code via the screen,
• Set a particular order and / or rhythm of touching the limited areas of the screen as code for activating a data entry.

The Data input preferably takes place via the screen itself. In a rhythm input for displaying the code can of course the entire screen as area for the Code input to be set.

In turn to prevent unauthorized persons from attempting to enter code, is with the computer program according to the invention until the code is input, a graphic signal is generated and sent to the screen which gives a uniform color and brightness on the Screen or what a pattern on the screen generated, which deviates from the course of the boundaries of the areas for the code input.

With other words running the program in the background and periodically checks the Input information of the touch screen. During this period will be either no display on the touch screen or a display, which has no association with the process of entering code.

First if the code is either by touching more localized surfaces entered completely in a specific order or rhythm was generated, the computer program generates a graphic signal, which the Input of data or commands via allows the touch screen. Also will be a control of the computer on which the computer program expires unlocked on the basis of the commands entered when the complete Code is entered.

Preferably an exit key is displayed on the control screen whose activity causes that this Computer program is placed in the initial mode, a neutral Display generates and continuously checks if the code is again Activation of data input was entered.

A embodiment The invention will be described below with reference to the accompanying drawings explained. The drawings show in:

1 a side view of a baking machine with a touch-sensitive screen;

2 an enlarged view of the in 1 recognizable touch-sensitive screen and

3 a schematic representation of a rhythmic code for activating a command input.

In 1 is the case 5 to recognize a baking machine, which serves the automatic production of baked goods, especially bread rolls, in sales rooms. It can also be any other vending machine.

In the upper right half is a touch-sensitive screen 6 arranged to input control commands in 2 is shown enlarged. The touch-sensitive screen 6 has a frame 7 as well as a function key bar 8th on, in the five function keys 9 are arranged. Next to the function key bar 8th is the touch-sensitive input field within the frame 10 arranged. Behind the touch-sensitive input field 10 is a TFT screen. This TFT screen displays a static logo in basic mode.

Further, in the basic mode, the input field 10 the touch-sensitive screen 6 in four equal quadrants 1 . 2 . 3 . 4 divided up. The boundaries between the input surfaces 1 . 2 . 3 . 4 are in 2 shown as a dashed line. On the actual device, these limits are not shown. It is therefore not apparent that the touch-sensitive screen 6 is controlled so that inputs in the four discrete quadrants are distinguished from each other.

The use of the touch-sensitive screen 6 However, authorized persons know that the touch-sensitive screen 6 evaluates the touches of its surface and when touched in a particular order, activates a computer program section that allows input of control commands. For example, the touch may be in the order of the quadrant 1 . 3 . 2 . 4 , ie in the form of an "X". Any other order of touch is possible.

It is also possible to divide the input field into other localized areas. It is also possible to use several different codes to activate the screen 6 permit. In this case, each code can be assigned to a specific person, so that possibly different authorizations for the control command input are enabled.

Alternatively to the particular order (eg, 1, 3, 2, 4), a certain rhythm of the touch may be interrogated as a code. For example, the shows 3 a rhythm, a long touch 11 , three short touches 12 and then again two long touches 11 represents. The touches can be assigned to different input surfaces. So the first long exposure 11 on the input surface 1 be requested. The three short touches 12 on the input surface 4 and the following three long touches 11 on the input surface 2 , But it is also possible to accept the rhythmic touches on any input surface.
