A self-service transaction terminal

Abstract: A self-service transaction terminal (2) has a user interface (6), the surface of a portion (18) of which is textured. Variation in the texture of the surface of said portion (18) forms a guide to guide a user towards an element (8) of the interface (6). The interface also includes additional elements (10,14,16) which the user may require in order to operate the ATM (2). Portions of the surface of the user interface (6) adjacent each of the additional elements (10,14,16) are also textured so as to form guide means to guide a user to each of the additional elements (10,14,16). The user interface (6) also incorporates an audio means (20) arranged to inform the user when he should move from one of the elements of the user interface to another. Thus the difficulty faced by visually impaired or blind people attempting to operate the self-service transaction terminal (2) is alleviated

Description: The invention relates to a self-service transaction terminal, and has application for example to an automated teller machine (ATM). Known ATMs commonly comprise: control means; a user interface through which the user communicates with the control means; a cash dispenser unit which is arranged to dispense cash to a user, under the control of the control means; and a printer which is arranged to print documents such as bank statements or account balances for a user, under the control of the control means. User interfaces in known ATMs commonly incorporate: a card input slot, connected to a card reader, for receiving a user identification card; a visual display screen for presenting information to, and requesting information from, a user; a key pad for inputting information ; a cash dispensing slot, connected to a cash dispenser unit, for dispensing cash to a user; and a printer output slot, connected to a printer, for dispensing printed documents to a user. The visual display screen, key pad, card input slot, cash dispensing slot and printer output slot are all normally mounted in a front fascia of an ATM (See US-A-5 185 515). However, there is no uniformity with regard to the layout of the various elements of the user interface between different ATMs. Due to the complexity of known user interfaces a user can find difficulty in locating specific elements of an interface such as the card input slot. This not only increases the time taken to operate the ATM but can also be frustrating for the user. It is known for ATM user interfaces to rely on visual means, such as lighting up elements of the interface, in an attempt to alleviate this problem. However, this solution is of limited assistance to users who are visually impaired and is of no assistance to those users who are blind. It is an object of the present invention to provide a self-service transaction terminal which alleviates the problem discussed above and which can be used by visually impaired or blind people. According to the present invention there is provided a self-service transaction terminal having a user interface, characterized in that the surface of a portion of the user interface is textured, variation in the texture of the surface of said portion forming a guide means to guide a user towards an element of the interface. An embodiment of the present invention will now be described, by way of example, with reference to the accompanying drawings in which: Fig. 1 illustrates a perspective view of an ATM in accordance with the present invention; Fig. 2 illustrates a schematic view of a portion of the surface of the user interface of the ATM of Fig. 1; and Fig. 3 illustrates a block circuit diagram of the ATM of Fig. 1. With reference particularly to Figs. 1 and 3, there is illustrated an ATM 2 in accordance with the present invention, which includes a control means in the form of a central processor unit (CPU) 4 which has stored therein a control program which controls the operation of the ATM 2 The ATM 2 includes a user interface 6 incorporating a card input slot 8, connected to a conventional card reader 9, for receiving a user identity card, a key pad 10 for inputting data, a visual display screen 12 for displaying user information, a cash dispensing slot 14 of a cash dispenser unit 17 for dispensing bank notes to a user, and a printer output slot 16 for dispensing printed documents to a user. The CPU 4 is connected to the card reader 9, the key pad 10, the display screen 12 and the cash dispenser unit 17. The CPU 4 is also connected to a conventional printer 11 for printing documents such as statements, receipts and account balances. The key pad 10 consists of an array of keys 13 each of which is located in a respective individual recess (not shown). Thus visually impaired or blind users ca differentiate between individual keys 13 and can therefore input information into the ATM 2 through the key pad 10. Referring particularly to Fig. 2 there is shown a part of a textured portion 18 of the surface of a user interface 6, in accordance with the present invention. The portion 18 surrounds the card input slot 8. Variation in the texture of the portion 18 forms a guide means to guide a user towards the card input slot 8, the portion 18 being rough at its outer edges and becoming smoother towards the card input slot 8. The textured nature of the portion 18 is produced by small protuberances 19 on the surface of the portion 18, and the change in texture is produced by increasing the density of the protuberances 19 and decreasing the size of each protuberance 19 towards the card input slot 8. Thus if a user touches the surface of the portion 18 of the interface 6 and moves his hand in the direction of the increasingly smooth surface he will be guided towards the card input slot 8. Additional elements of the user interface 6, namely the key pad 10, the cash dispensing slot 14 and the printer output slot 16 are each provided with respective textured portions (not shown) which form guide means to guide the user to each of the additional elements. Thus as a visually impaired or blind user will normally be aware of the approximate location of each of the elements of the user interface 6 in relation to each other he can locate the textured portions of the surface of the interface 6 surrounding each of the required elements in turn and use the respective textured portions of the surface to guide him to the exact location of each element. The user interface 6 also includes an audio means 20 (Fig. 3) arranged to provide a visually impaired or blind user with an indication that he should move from one element of the user interface 6 to another. For example, once the user has input his card into the card input slot 8 and the card has been read by the card reader 9 the user must move to the key pad 10 and input information into the ATM 2. Once the card reader has read the user's card the audio means will produce an audio signal to indicate to the user that he should move to the key pad 10. If the user requests the dispensing of cash, the CPU 4 will instruct the cash dispenser unit 17 to dispense cash to the user via the cash dispensing slot 14. Prior to this the CPU 4 will instruct the audio means 20 to produce the audio signal to inform the user that cash is about to be dispensed, so that he can move his hand to the cash dispensing slot 14 before the cash is dispensed. Further audio signals will be produced before a printed document or the user's user identification card are presented for collection, so the user can move his hand to the printer output slot 16 and the card input slot 8 prior to these items being presented. In operation, the ATM 2 is accessed by the user inserting a user identification card into the card input slot 8. The user is guided to the card input slot 8 by touching the roughened surface of the portion 18 of the user interface 6 and moving his hand in the direction of the increasingly smooth surface until he reaches the card input slot 8. The card reader 9 within the ATM 2 reads the card and transmits information read from the card to the CPU 4. The information will include an encrypted PIN number which must be entered by the user to enable access to the ATM 2. In normal operation, the CPU 4 then causes the visual display screen 12 to present a display requesting the input of the required PIN number by the user, in order to confirm that the user is authorised to use the card. A visually impaired or blind user will know that the ATM 2 requires information, including a PIN number and accordingly after he has inserted the user identification card in the card input slot 8, and heard the audio signal discussed above, he will move his hand to the approximate area of the key pad 10 and locate the textured portion (not shown) of the surface of the interface 6 adjacent the key pad 10 and use this textured portion to locate the key pad 10 precisely. The user can then input the information required by the ATM 2, in order to process his transaction. Once the user has input the information into the ATM 2 he will be required, for example, to remove cash from the cash dispensing slot 14, remove a statement or receipt from the printer output slot 16, and remove his user identification card from the card input slot 8. The user will locate the cash dispensing slot 14, the printer output slot 16 and the card input slot 8 by utilizing the textured portions of the surface of the interface 6 adjacent each of these elements of the user interface 6, as discussed above. Also as discussed above, the user will await the audible signal from the user interface 6 to instruct him to move from the element of the interface 6 he is presently using to the next element of the interface 6.
