Description

ARRANGEMENT FOR SIMPLIFYING ORDERING OF TELECOMMUNICATION SERVICES

Technical Field

The present invention relates to an arrangement for simplifying communication between a user and a tele¬ communication unit connected to a telephone network. Connected to the telecommunication unit is an options menu which presents the options that can be selected. The arrangement also includes a selection control unit by means of which movement in the menu is effected and different options can be selected.

Background Art

In order to be able to meet the large number of tele¬ phony services that will become available in the future, it will be necessary to provide a simple interface between a user and a telecommunication unit connected to a telephone network. For instance, EP 463,856 teaches a mobile telephone which includes an options menu in which telephone service options are presented visually. These telephone services can be chosen either by pressing keys or buttons on the mobile or by manoeuvering other manoeuvering devices provided on the mobile, for instance a thumb wheel. Since the driver of a vehicle must often concentrate solely on his/her driving, it is essential in the field of mobile telephony to eliminate all external, disturbing procedures, such as the procedures taken when calling a subscriber. One problem with present- day known technology resides in the difficulty experi¬ enced in viewing the options menu and/or making a selection with the aid of the manoeuvering device during an ongoing call/conversation at the same time, while driving the vehicle. The aforesaid problems have been intensified by recent proposals to forbid the use of mobile telephones while driving a motor vehicle. At present, intensive developments are being undertaken within the technical field of user-friendly interfac¬ es, and one solution of the many solutions proposed resides in an auditive interface known under the description "Bank queries/transactions by telefon". The problem with this type of interface is that it is necessary for the user to insert a code or to confirm a selection manually, for instance with the aid of a keypad. In the case of some professional groups or occupations, such as rescue services, police or secu¬ rity guards for instance, it is extremely important that the people involved are able to work with their hands while undisturbed and without needing to change their line of vision while requesting a particular telephone service.

Disclosure of the Invention

The object of the present invention is to simplify the ordering of telephony services. This object is achieved in accordance with the present invention by combining or replacing the existing visual menu of a telecommunication unit with an auditive options menu from which the telephone services available on the menu are recited audibly. The menu control unit is an auditive unit, i.e. receives and responds to voice commands. The invention is characterized by the char¬ acteristic features set forth in the following Claims.

Brief Description of the Drawings

The invention will now be described in more detail with reference to exemplifying embodiments thereof and also with reference to the accompanying drawings, in which

Figure 1 is a perspective view of a mobile telephone which includes an inventive auditive options menu and an auditive menu control unit; Figure 2 illustrates in perspective and in two sepa¬ rate illustrations a portable telephone which includes an inventive auditive menu control unit and an audi¬ tive menu; and Figure 3 is a block diagram illustrative of an inven¬ tive telephone.

Best Mode of Carrying Out the Invention.

Figure 1 illustrates a mobile telephone, referenced generally 1, for use within a cellular mobile tele¬ phone network. The mobile telephone includes an adapt¬ er unit, generally referenced 2, which is mounted in a motor vehicle, and a mobile telephone unit, generally referenced 3, which rests against the adapter unit. The mobile telephone 1 also includes a communication unit, generally referenced 4, which communicates with the telephone unit 3 through the agency of cordless transmission.

Although not shown in Figure 1, the adapter unit 2 includes a unit charging device, and magnets are mounted on that side of the adapter which faces to¬ wards the telephone unit 3 and function to hold the telephone unit in its charging position.

The telephone unit 3 presents on that side of the unit which is remote from the adapter unit a keypad 31 which is comprised of twelve buttons or keys by means of which standard services are ordered and put into effect within the context of telephony, such as the manual dialling of a telephone number for instance. In order to meet the many telephone services that are already available and also those which can be expected to be added in the future, the fixed unit includes a visible menu display 32 on which different selectable telephone services, i.e. service options, can be presented in addition to the aforesaid standard services. The visual menu display will be large enough to display, for instance, five telephone services simultaneously. A cursor 33 marks one of the five visible services. The options menu is a scrolling menu, i.e. a menu in which additional telephone services can be made visible, by moving the cursor up or down, i.e. in a direction away from or towards the earlier mentioned keypad 31. The telephone unit 3 also includes a speech receiving device (not shown in Figure 1) and a conventional sound reproduction 34 on that side of the telephone unit which lies proximal to the adapter unit 2. Mounted on one of the long sides of the telephone unit 3, between the two aforesaid sides, is a first antenna 35 which functions to trans- mit signals to and to receive signals from a second antenna 45 mounted on the communication unit 4.

The communication unit 4 includes a resilient, curved member 41. Mounted on one end of the curved member 41 is a so-called auditive options menu 42, which is described in more detail further on, while the other end of the curved member 41 carries an attachment arm 43 to which an auditive menu control unit 44 is at¬ tached, this unit also being described in more detail further on. The communication unit 4 also carries the aforesaid second antenna 45 by means of which signals are transmitted to and received from the aforesaid first antenna 35.

The auditive menu 42 and the menu control unit 44 are both connected electrically to the second antenna 45. The electrical connections extend within the curved member 41 and the attachment arm 43 respectively and are therefore not visible in Figure l. In the illus- trated embodiment, the curved member 41 is intended to be fitted over the user's ears and fastened so that the sound emitted by the auditive options menu will be heard clearly by the user. The auditive options menu 42 includes a loudspeaker and a menu processor in which data relating to the telephone service indicated by the cursor 33 at that moment is stored, and con¬ verts this data to speech signals which can be heard in the loudspeaker. The data fed to the menu processor is received from the visual menu over the aforesaid antennas 35, 45. Thus, the earlier mentioned telephone services presented visually on the display are presented in speech form in the auditive menu 42. A sound marker in the auditive menu has the same function as the aforesaid cursor 33, i.e. the user is able to discern when the cursor has moved in the menu, with the aid of an audible tone. The nature of respective telephone services presented in the audi¬ tive menu is the same as that presented on the visual menu 32. Both the visual and the auditive menu are constructed hierarchically, i.e. they are comprised of rank ordered menus, as described in more detail further on.

The auditive menu control unit 44 is adjustable in relation to the curved member 41, and can be moved to a position in which said unit will clearly understand the sounds uttered by the user. The auditive control unit 44 includes a microphone and an audio processor, which converts the sound incoming from the microphone to data form. The data is sent from the audio proces¬ sor to the visual menu over the aforesaid antennas 35, 45. Thus, the cursor 33 and the marker can be con¬ trolled by both the visual menu 32 and the auditive menu 42 with the aid of voice commands, i.e. the options are read-out from the auditive menu at the same time as the cursor 33 moves through the visual menu.

The communication unit 4 can be used as an extension of the aforesaid speech receiving device and the sound reproduction device 34 during the course of an ongoing call. According to the invention, the communication unit 4 can also be used to control the visual options menu, as before described. The switch between the audio and visual use of the arrangement is effected with the aid of voice commands, as described in more detail further on. The coaction between the various components of the inventive arrangement are also described below, with reference to a block schematic.

An example of how the inventive arrangement can be used to call a subscriber will now be described, although by way of illustration only:

- The user initiates activation of the menu control with a first voice command START.

- The cursor 33 is then stepped in a first direction away from the traditional keypad 31, by issuing a second voice command UP. Alternatively, the. cursor 33 is stepped in the other direction, towards the tradi¬ tional keypad 31, by issuing a third voice command DOWN. The marker in the auditive menu 42 will move at the same time as the cursor moves in a main menu on the visual menu display 32, wherewith the telephone services that coincide with the position of the audio- menu marker are read-out to the user after the tone signal from the marker.

The telephone service desired is located in the menu, which in the illustrated case is the service "directory".

- The user selects the "directory" service, with a fourth voice command SELECT.

- A first submenu containing subscriber names in alphabetical order is presented on the visual menu display 32 at the same time as the name to which the cursor 33 and the marker point are read-out from the auditive menu 42.

- A search is made through the option menus 32, 42 in the same way as that described above, in response to the second and/or third voice commands.

- The name required is located.

The user selects the name desired through the fourth voice command SELECT. A second submenu containing personal data, for instance addresses and telephone numbers, is shown on the visual menu display 32, at the same time as the data to which the cursor 33 and the marker point is read-out from the auditive menu into the loudspeaker 42.

The cursor/marker are moved to the desired tele¬ phone number, in the aforedescribed manner.

- The user orders the telephone unit to call the indicated number, through a fifth voice command CALL.

- When the call has been connected, the user orders deactivation of the menu control through a sixth voice command STOP, wherewith the communication unit 4 again functions as an extension of the sound reproduction and speech receiving device of the telephone unit.

It will be understood that the aforedescribed embodi¬ ment may be modified within the scope of the inven¬ tion. For instance, the aforementioned voice commands can be optimized to a few common commands. For in¬ stance, the voice commands SELECT and CALL can be replaced with the single command YES. The described menu and audio processors may be mounted in the tele¬ phone unit 3 instead of in the communication unit 4, thereby reducing the size of the latter. The communi¬ cation unit 4 may include an auditive options menu and/or control unit firmly mounted on the vehicle chassis. The auditive options menu may, for instance, have the form of an earmuff while the auditive control unit may, for instance, have the form of a stocking microphone. The aforesaid tone from the marker in the auditive menu may be excluded and replaced, for in¬ stance, solely with the spoken message.

Figure 2 illustrates another exemplifying embodiment of the invention. The embodiment illustrated in Figure 2 comprises a portable telephone, generally referenced 100, which may be used in an office environment for instance. The telephone is shown in two different views, namely a view towards the rear surface 101, i.e. the surface that lies distal from the user in use, and a view towards the front surface 102, i.e. the surface that lies proximal to the user in use. Mounted on the front surface 102 is a twelve-button keypad 103 by means of which standard services within the telephony field can be instigated, such as the manual selection of a telephone number for instance. Mounted on the rear surface 101 of the telephone is a visual menu display of the kind described with refer¬ ence to the earlier embodiment. A cusor 105 points to the service options available on the menu, which may have the following nature:

The user wishes to leave a short-absence message. - The user wishes to leave a message to the effect that he is ill, away on business or on vacation.

- The user wishes to enquire whether he has been paged during his/her absence.

- The user chooses not to accept one or more of the incoming calls.

The front surface 102 of the telephone 100 shown in Figure 2 incorporates an auditive options menu 106, shown in broken lines, which includes a loudspeaker 107 and a menu processor, not shown in Figure 2. In principle, the auditive menu 106 functions in the same manner as the auditive menu described with reference to the earlier embodiment, i.e. the menu processor reads-in data from the visual options menu 104 and converts this data to audible speech with the aid of the loudspeaker 102. The front surface 102 of the telephone 100 further embodies an auditive control unit 108, shown in broken lines in Figure 2, a micro¬ phone 109 and an audio processor, not shown in Figure 2. In principle, the auditive control unit 108 func¬ tions in the same manner as the control unit described with reference to the earlier embodiment, i.e. the audio processor reads-in audible speech from the microphone 109 and converts the sound to data signals that are used to control both the visual menu 104 and the auditive menu 106, in the same way as that de¬ scribed with reference to the earlier embodiment.

A brief explanation will now be given of the way in which one of the aforesaid telephone services can be utilized with the aid of the inventive arrangement:

- The menu control is activated by means of a voice command of the same type or a similar type to that earlier mentioned, and the user selects the service "Short Absence" from the options menus 104, 106.

- A submenu which lists different time options, such as 15, 30 or 45 minutes for instance, is shown on the visual menu 104 and is read out from the auditive menu 106 in the same manner as that earlier described.

Using a voice command, the user searches for and selects in the menus 104, 106 the anticipated duration of his/her absence, wherewith all incoming calls are referred to a central exchange during this time period.

- Menu control is deactivated.

The embodiment illustrated in Figure 2, also includes a manoeuvering device 110 of known kind, indicating that the inventive auditive control of the options menus may also be combined, for instance, with a known electromagnetic manoeuvering means. In this case, the aforesaid voice commands may coincide in name and number with those given on the manoeuvering means 110, so as to enable both control units to be used in parallel.

Figure 3 is a functional block schematic which illus¬ trates an exemplifying embodiment of an inventive telephone set. The arrangement includes a central unit to which there is connected a display, a menu proces¬ sor and an audio processor. The display constitutes the earlier mentioned visual options menu. A loud¬ speaker is connected to the menu processor and together the two units constitute the earlier men¬ tioned auditive options menu. A microphone is connect¬ ed to the audio processor and the two units together constitute the earlier mentioned auditive options control unit. The menu processor and the audio pro¬ cessor together with the loudspeaker and the micro¬ phone handle conversion of data to sound, and vice versa. The central unit handles the transport of data between the different units, namely between the visual menu, the auditive menu and the auditive selection control unit. It should be mentioned that the illus¬ trated block schematic shall only be seen as an exam¬ ple of an inventive arrangement. It will be obvious to the person skilled in this art that changes can be made without transgressing from the concept of the inventive arrangement.

It will be understood that the aforedescribed and illustrated embodiments of the invention can be modi- fied and varied within the scope of the present inven¬ tion. The telephone unit can be optionally connected to a fixed telephone network, a cellular, cordless telephone network for internal environments or a mobile telephone network for external environments. Furthermore, the combination comprising control unit and visual and/or auditive options menu may be made selective, provided that the combination is kept within the scope of the invention. Since it is often easiest for the user of auditive units to recognize his/her own voice, it is conceivable to replace the synthetic voice in the auditive menu with, for in¬ stance, a recording of the user's own voice. It will be obvious to the skilled person that the auditive control unit can be constructed to receive solely the user's voice, which can be an important feature from the aspect of reliability and security. Naturally, the type of voice command and the number of voice commands required to locate and perform the correct telephone service may vary in accordance with the requirements of the designer. It will be evident that the invention is not restricted to the aforedescribed and illustrat¬ ed exemplifying embodiments thereof and that modifica¬ tions can be made within the scope of the following Claims.
