`TELECOMMUNICATIONS TERMINAL
`INTERFACE FOR CONTROL BY
`PREDETERMINED GESTURES
`
`TECHNICAL FIELD
`
`The present invention is limited to telecommunications
`terminals having touch-sensitive input/output units.
`
`BACKGROUND OF THE INVENTION
`
`Communications devices for displaying and transmitting
`graphics information with a screen which is covered by a
`transparent panel via which the graphics information is input
`by touching an area on the panel are known (DE 34 09 532
`C2). Either display and transmission of graphics information
`or voice communication is possible. The transparent panel is
`divided into a first portion for graphical representation and
`a separate, second portion for the functions that can be
`activated by touching an area of the panel. Thus, both
`graphical representations and telephone functions are
`possible, but they are strictly separated. In particular, a
`"graphics display" mode is possible in which the functional
`representations in the second portion of the panel also
`change into function fields for this mode. Thus it is always
`necessary to switch between a "phone" mode and a "graph(cid:173)
`ics display" mode.
`Also known are so-called Personal Digital Assistants
`(PDAs), which have a touch-sensitive LC display that is
`operable by means of a plastic pen. Specifically developed
`software for handwriting and graphics recognition makes it
`possible to call functions, such as directory, scheduler. and
`notebook. by pen input. A specific "assistant" function,
`which is displayed as an icon and only needs to be tapped,
`recognizes up to seven keywords to send telephone
`numbers, fax numbers, mail numbers, etc., such numbers
`being also selectable via an optionally connectable modem
`for, e.g., fax. Thus, by handwritten input in combination
`with icons, all functions required to organize an office can be
`activated (Apple Newton MessagePad, Funkschau 19/1993,
`pp. 16--17).
`
`SUMMARY OF THE INVENTION
`
`The technical problem underlying the invention is how to
`implement a telecommunications terminal which is much
`more convenient to operate.
`The telecommunications terminal according to the inven(cid:173)
`tion implements a multimedia terminal wherein control of
`the telecommuncations functions is effected via a graphical
`user interface. An optical input-output unit makes it possible
`to activate or deactivate the telecommunications functions
`by inputting graphic elements, such as lines, circles, letters,
`and digits, which are converted by handwriting-recognition
`software. Adventageously, use is made of a so-called
`window-oriented user interface.
`A special advantage for the user of such a telecommuni(cid:173)
`cations terminal is that by touching areas on the touch(cid:173)
`sensitive input-output unit and inputting graphic elements,
`so-called gestures, with a simple pen. the entire prompting
`is effected, since all functions and their current states can be
`displayed visually, e.g., in clear text or by means of symbols.
`Further advantageous aspects of the subject matter of the
`invention are apparent from the following description.
`
`BR1EF DESCRIPTION OF THE DRAWINGS
`One embodiment of the invention will now be explained
`with reference to the accompanying drawings, in which:
`

`F1GS. lA-lH show an input/output unit of the telecom(cid:173)
`munications terminal according to the invention with
`prompts and inputs for initiating an outgoing call;
`F1GS. 2A-2D show an input/output unit with prompts and
`inputs for accepting an incoming call, and
`F1GS. 3A-3H show an input/output unit with prompts and
`inputs for establishing a conference connection.
`BESf MODE FOR CARRYING our THE
`INVENTION
`A telecommunications terminal according to the invention
`contains a large-area touch-sensitive input-output unit 1. the
`figures illustrating only the prompting on the input-output
`unit 1. The input-output unit 1 may be the product "Newton
`15 MessagePad" of Apple Computer, for example, and may be
`incorporated in the telecommunications terminal as a touch(cid:173)
`sensitive display to provide a user interface (see Funkschau
`19/1993. pp. 16--17, Apple Newton MessagePad). Accord(cid:173)
`ing to the invention, the software available for recognizing
`20 writing and graphics is used to recognize predetermined
`graphic elements, so-called gestures, via the input-output
`unit 1 under control of a controller of the telecommunica(cid:173)
`tions terminal, and to activate or deactivate telecommuni(cid:173)
`cations functions 2 which can be displayed on the input/
`25 output unit 1.
`The other hardware/software parts of a telecommunica(cid:173)
`tions terminal which are required to control a multitude of
`telecommunications functions, such as connection set-up/
`release, conference connection, etc., to the extent that they
`30 do not form part of the present invention, are described, for
`example, in an article by F. Bergler and E. Foth, ''Multime(cid:173)
`dia Communications Using the Alcatel 2824 ISDN
`Telephone", Electrical Communication, 4th Quarter. 1993.
`pp. 394-401. The ISDN telephone described there, the
`35 Alcatel 2824 of Alcatel SELAG, Stuttgart. serves as a basis
`for the telecommunications terminal according to the inven(cid:173)
`tion. Instead of the display indicated in F1G. 1 on page 396
`of that article, the Apple Newton MessagePad has to be
`incorporated. The operation of the telecommunications ter-
`40 minal according to the invention will now be described with
`reference to several scenarios.
`Starting from an idle state of the terminal, the initiation of
`an outgoing call in accordance with the invention will be
`described. assuming that there is a window -oriented user
`.
`~
`interface for visually displaying the various telecommuru-
`cations functions.
`As shown in F1G. IA. in the idle state, a telephone symbol
`4, which serves to request telecommunications functions, is
`50 displayed on the input/output unit 1. The icons shown at the
`lower left, such as time of day, will not be explained here,
`since they are not essential for the invention.
`After input of a graphic element, e.g. in the form of a tick
`on symbol 14, by means of a pen 9, a window 5 is opened
`55 to display the possible telecommunications function (see
`FIG. IB). If the telecommunications function FKT "select"
`is now activated, a further window 6 will be opened to
`indicate that the desired call number is to be entered ( see
`FIG. IC). The call number, here 8696154, can now be
`60 entered in the form of graphic elements, such as digits or
`letters. The software for handwriting recognition performs a
`recognition and causes the call number 8696154 to b:
`displayed in the window 6 (see F1G. 1D). The control urut
`of the telecommunications terminal then controls the setting
`65 up of the desired connection in the usual manner.
`Instead of inputting a call number, a name may be written.
`which, if recognized correctly, causes an associated call
`

`
`

`

`
`3
`number stored in a memory to be read out and used for
`selection. Instead of digit/or letter inputs, arbitrary gestures
`designed by the user and trained in the software for hand(cid:173)
`writing recognition can be stored in the memory as abbre(cid:173)
`viations of call numbers, and thus used for selection.
`As shown in FIG. lE, the subscriber with call number
`8696154 is now being called. According to the invention, by
`activating a telecommunications functions, here "ringing", a
`visual display of the signalling states can be given on the
`input-output unit 1 in the form of letters and/or symbols,
`instead of producing audible sounds. It is also possible, of
`course, to display the signalling states in addition to pro(cid:173)
`ducing the audible sounds.
`As shown in FIG. lE, in a window S, the word "ringing"
`is displayed in addition to the call number. After a connec(cid:173)
`tion has been established. FIG. IF, the call number and the
`state "connected" are displayed in window S. In addition, the
`subscriber's name associated with the call number can be
`displayed if a corresponding association is stored in the
`memory. Under control of the control unit, a hands-free
`facility is connected, this being indicated by a symbol
`representing a speaker.
`According to the invention, while an activated "con(cid:173)
`nected" function is displayed in window S, a further window
`6 is opened. so that further functions FKT are callable.
`If a user now wants to deactivate the "connected"
`function, i.e., to terminate the call. he or she can, according
`to the invention, release the connection by inputting a
`graphic element 3. such as a letter M or W, which is written
`across the opened window S, see FIG. lG. This is displayed
`in window S by ''released", see FIG. lH. and the input(cid:173)
`output unit 1 is then restored to the idle state, see FIG. lA.
`Any function can thus be terminated without the user
`having to retain any input codes or any particular push- 35
`button input combinations. This is particularly advantageous
`if within a function, further activated functions are to be
`deactivated, as will be explained below.
`The function "incoming call" will now be explained with
`the aid of FIGS. 2A-2D.
`An incoming call opens window S and is indicated on the
`input-output unit 1 by the call number 07231150 and the
`word "call". A symbol representing the signalling state
`"incoming call" may be a sort of "blinking" radiating lines
`10 around the displayed information, see FIG. 2A. If the 45
`symbol for requesting telecommunications functions, here
`the telephone symbol, is now activated by inputting a
`graphic element or by touching the symbol with the pen, the
`call will be accepted, i.e., a connection will be established
`and. at the same time, the hands-free facility symbol: 50
`speaker 11, will be connected, with the call number, possibly
`together with the name of the caller, and the word "con(cid:173)
`nected" being displayed in window S (see FIG. 2B). Here,
`too, the possibility of calling further functions may be
`indicated in a further window 6. The connection is released 55
`in a manner analogous to that described with reference to
`FIGS. lG and lH, namely by inputting a graphic element 3,
`here a letter M. see FIGS. 2C and 20.
`The establishment of a conference connection by means
`of the telecommunications terminal according to the inven(cid:173)
`tion will now be described with reference to FIGS. 3A to 3H.
`Starting from an existing connection, see FIG. 3A, the
`function "enquiry" is activated by input via the further
`window 6. see FIG. 3B. As a result, the function
`"connected", which is being displayed in window S. is
`changed to the function "held", see FIG. 3C, and at the same
`time. the call number to be selected for the enquiry appears
`
`4
`in the further window 6. The user can now enter the desired
`call number, as already explained in connection with FIG.
`IC. After recognition, the call number, here 8696154, is
`confirmed, see FIG. 3D, and the subscriber with call number
`5 8696154 is called, see FIG. 3E. To symbolize the state
`"held". a "transparent" line 12 from the telephone symbol 4
`to window S is displayed, whereas the activated function
`''ringing" is represented by a corresponding heavy line 13
`( see FIGS. 3E and 3F). After the enquiry call has been set up,
`10 FIG. 3F. a conference connection can be established. To do
`this, a graphic element 3 is input, here by drawing a line
`between window S and the further window 6. Through this
`simple and very easily remembered gesture. see FIG. 3G, a
`conference connection is established, which is affirmed by
`15 the word "conference", see FIG. 3H.
`According to the invention, in this state, i.e., display of the
`function "held" in window S and display of the function
`"connected" in the further window 6, a "call transfer"
`function can be activated. To do this, a gesture in the form
`20 of a circle (not shown) around window S and the further
`window 6 is input. which activates this function. Thereafter,
`either a return to the idle state is possible or any further
`function, such as the selection of another subscriber number,
`can be activated.
`This feature, in particular, illustrates the ease of operation
`of the telecommunications terminal according to the inven(cid:173)
`tion.
`Analogously to the functions described with reference to
`FIGS. 1 to 3, all other functions can be activated or deac(cid:173)
`tivated by input of gestures.
`We claim:
`1. A telecommunications terminal comprising a large-area
