Description

Mobile Telekommunikationseinheit mit verbessertem BedienungskomfortMobile telecommunication unit with improved ease of use
Die Erfindung bezieht sich auf eine mobile Telekommunikationseinheit mit verbessertem Bedienungskomfort.The invention relates to a mobile telecommunications unit with improved ease of use.
Moderne Kommunikationsgeräte, beispielsweise Mobiltelefone, müssen in zunehmendem Maße zusätzliche Funktionen und Anwendungen bewältigen können. Die Größe und das Gewicht des Gerätes als Qualitätsmerkmal von Mobilität und Transportierbarkeit stehen oft der Bedienerfreundlichkeit, Handhabbarkeit und der Datenzugänglichkeit entgegengesetzt gegen- über. Beispielsweise wird in WO 97/09813 ein Kommunikationsgerät beschrieben, welches eine Vielzahl von Tasten sowie ein großformatiges Display aufweist. Infolgedessen nimmt die Größe des Gerätes gegenüber herkömmlichen Mobiltelefonen zu, was zu einer Verringerung der Mobilität führt. Des weiteren nimmt auch die Störanfälligkeit des Gerätes zu. Die Schmutz-, Staub-, Feuchtigkeits- und Druckempfindlichkeit der Vielzahl von Tasten sowie großformatiger LCD-Displays sind hinlänglich bekannt. Ebenso sind LCD-Displays recht empfindlich gegenüber Temperaturschwankungen. Die WO 94/11980 beschreibt ebenfalls ein mobiles Kommunikationsgerät, welches zusätzlich eine Eingabe mittels Lichtstift und Grafik- tableau erlaubt. Auch Lichtstifte und Grafiktableau sind als Eingabegeräte für Mobiltelefone wegen ihrer Störanfälligkeit und Empfindlichkeit gegenüber Schmutz, Druck und Tempera- turschwankungen nicht immer geeignet. Die DE 195 47 809 AI beschreibt ein Mobilfunkgerät mit integriertem Faxgerät. Als zusätzliches Eingabegerät neben der Tastatur ist eine Scanzeile an einer Gehäuseseite angeordnet. Die Scanzeile unterliegt sowohl beim Transport als auch beim Gebrauch Umwelteinflüssen in Form von Schmutz, Staub und Feuchtigkeit, die die Funktionsweise beeinträchtigen können. Die Funktionsauswahl erfolgt über die übliche Tasta- tur, so daß eine Bedienung der vielfältigen Funktionen die Handhabung des Gerätes erschwert. Andere bekannte, relativ einfache Mobiltelefone ohne zusätzliche Eingabegeräte, erweiterte Tastaturen oder vergrößerte Displays sind dadurch gekennzeichnet, daß die Tastatur unterhalb des meist einzeiligen Displays angeordnet ist. Die Bedienbarkeit, insbesondere mit einer Hand, ist jedoch eingeschränkt, da der Auflagepunkt des Mobiltelefons bei einer derartigen einhändigen Benutzung nicht direkt unterhalb des Schwerpunkts liegt bzw. die leichte Bedienbarkeit von der Beweglichkeit der Finger des Benutzers abhängig ist. Gerade bei einer Vielzahl von Eingaben über die Tastatur ist dies oft nicht mehr gewährleistet.Modern communication devices, such as mobile phones, have to be able to handle additional functions and applications to an increasing extent. The size and weight of the device as a quality feature of mobility and portability often contrast with ease of use, manageability and data access. For example, WO 97/09813 describes a communication device which has a large number of buttons and a large-format display. As a result, the size of the device increases compared to conventional mobile phones, which leads to a reduction in mobility. Furthermore, the susceptibility of the device to interference increases. The dirt, dust, moisture and pressure sensitivity of the large number of buttons and large-format LCD displays are well known. LCD displays are also very sensitive to temperature fluctuations. WO 94/11980 also describes a mobile communication device which additionally permits input by means of a light pen and graphic panel. Light pens and graphic tablets are also not always suitable as input devices for mobile phones because of their susceptibility to interference and sensitivity to dirt, pressure and temperature fluctuations. DE 195 47 809 AI describes a mobile radio device with an integrated fax machine. As an additional input device next to the keyboard, a scan line is arranged on one side of the housing. The scan line is subject to environmental influences in the form of dirt, dust and moisture during transport and use, which can impair its functionality. The function is selected using the usual keyboard, so that operating the various functions makes handling the device more difficult. Other known, relatively simple mobile phones without additional input devices, Extended keyboards or enlarged displays are characterized in that the keyboard is arranged below the mostly one-line display. The usability, in particular with one hand, is limited, however, since the point of contact of the mobile phone with such a one-handed use is not directly below the center of gravity or the ease of use is dependent on the mobility of the fingers of the user. This is often no longer guaranteed, especially when a large number of entries are made via the keyboard.
Aufgabe der Erfindung ist es, eine mobile Telekommunikationseinheit mit verbessertem Bedienungskomfort vorzuschlagen, mit dem ohne zusätzlich anzuschließende externe Eingabe- gerate Informationen abgesandt werden können. Die Ausmaße und das Gewicht der mobilen Telekommunikationseinheit sollen sich dabei nicht wesentlich von denen der heute auf dem Markt befindlichen mobilen Telefone unterscheiden. Des weiteren ist es Aufgabe der Erfindung, daß die mobile Telekommunikationseinheit einfach und unkompliziert softwaremenü- gesteuert bedient werden kann. Diese Aufgabenstellung wird erfmdungsgemäß dadurch gelöst, daß bei einer mobilen Telekommunikationseinheit mit einer Telefoneinheit die Tastatur oberhalb des Displays auf der Front des Gerätes angeordnet ist. Durch diese neuartige Anordnung kann die Tastatur mit dem Daumen bedient werden, während das Gerät sicher in der Hand liegt und das Display weiterhin gut abzulesen ist. Zusätzlich kann die Software des Menüs so gestaltet sein, daß eine Bedienung über mindestens ein zusätzliches Eingabegerät erfolgt. Diese zusätzlichen Eingabegeräte befinden sich auf der Rückseite der mobilen Telekommunikationseinheit. Diese können dort mit dem Zeigefinger in verkrampfungsfreier Handstellung bedient werden. Als zusätzliches Eingabegerät wird erfindungsgemäß ein Trackball, ein Rad, eine Drehscheibe, eine Walze, ein Koordinaten- Schieber, ein 3D-Trackpad und/oder ein Joystick verwendet. Die Merkmale der Erfindung gehen außer aus den Ansprüchen auch aus der Beschreibung und den Zeichnungen hervor, wobei die einzelnen Merkmale jeweils für sich allein oder zu mehreren in Form von Unterkombinationen schutzfähige Ausfrihrungen darstellen, für die hier Schutz beansprucht wird. Ausführungsbeispiele der Erfindung sind in den Zeichnungen dargestellt und werden im folgenden näher erläutert.The object of the invention is to propose a mobile telecommunications unit with improved ease of use, with which information can be sent without additional external input devices to be connected. The dimensions and weight of the mobile telecommunication unit should not differ significantly from those of the mobile telephones currently on the market. Furthermore, it is an object of the invention that the mobile telecommunication unit can be operated in a simple and uncomplicated manner controlled by software. This task is solved according to the invention in that in a mobile telecommunication unit with a telephone unit the keyboard is arranged above the display on the front of the device. With this new arrangement, the keyboard can be operated with the thumb while the device lies securely in the hand and the display is still easy to read. In addition, the software of the menu can be designed so that it is operated via at least one additional input device. These additional input devices are located on the back of the mobile telecommunication unit. These can be operated with the forefinger in a cramp-free hand position. According to the invention, a trackball, a wheel, a turntable, a roller, a coordinate slide, a 3D trackpad and / or a joystick is used as an additional input device. In addition to the claims, the features of the invention also emerge from the description and the drawings, the individual features each representing protectable designs, individually or in groups in the form of sub-combinations, for which protection is claimed here. Embodiments of the invention are shown in the drawings and are explained in more detail below.

Als Display 3 wird je nach Anwendungszweck ein ein- oder mehrzelliges LCD-Display oder ein grafikfähiges LCD- Display verwendet. Fig. 2 zeigt die Rückseite 5 des Mobiltelefons 1. In die Rückseite 5 ist ein gerasterter Trackball 6 als zusätzliches Eingabegerät integriert. Eine Rasterung des Trackballs 6 bietet eine vertikale und horizontale Orientierungshilfe. Die in der Fig. nicht dargestellten Abnehmerwalzen der X- und Y-Achsen des Trackballs 6 sind ebenfalls gerastert. Dies ermöglicht eine bessere Zeilen- und Spaltenführung. Ein ungewolltes Drehen des Trackballs 6 wird verhindert.1 shows a mobile phone 1 in which a keyboard 2 is arranged above a display 3 on the front 4 of the mobile phone 1. With this arrangement according to the invention, the keyboard 2 can be operated with the thumb while the mobile phone 1 remains securely in the hand. The display 3 is still easy to read. Depending on the application, a single or multi-cell LCD display or a graphics-capable LCD display is used as the display 3. Fig. 2 shows the back 5 of the mobile phone 1. In the back 5, a rasterized trackball 6 is integrated as an additional input device. A grid of the trackball 6 offers a vertical and horizontal orientation aid. The take-off rollers of the X and Y axes of the trackball 6, not shown in the figure, are also rasterized. This enables better row and column guidance. An unwanted rotation of the trackball 6 is prevented.
Beispiel 2:Example 2:
In Abwandlung zum ersten Ausfuhrungsbeispiel ist in die Rückseite 5 des Mobiltelefons 1 ein drehbar gelagertes Rad 7 als zusätzliches Eingabegerät integriert, wie in Fig. 3 dargestellt. Eine Rasterung des Rades 7 unterstützt kontrollierbare Zeilensprünge. Die Anordnung des Rades 7 in der Mitte der Rückseite 5 ermöglicht eine Einhandbedienung gleichermaßen für Links- und Rechtshänder.In a modification of the first exemplary embodiment, a rotatably mounted wheel 7 is integrated into the rear side 5 of the mobile telephone 1 as an additional input device, as shown in FIG. 3. A grid of the wheel 7 supports controllable line jumps. The arrangement of the wheel 7 in the middle of the back 5 enables one-handed operation equally for left and right-handers.
Beispiel 3 :Example 3:
In Abwandlung zu den vorhergehenden Ausführungsbeispielen ist in die Rückseite 5 des Mobiltelefons 1 eine Drehscheibe 8 als zusätzliches Eingabegerät integriert, wie in Fig. 4 dargestellt. Eine Rasterung der Drehscheibe unterstützt kontrollierbare Zeilensprünge. Die Anordnung der Drehscheibe 8 in der Mitte der Rückseite 5 und ein leichtes seitliches Hinausragen der Drehscheibe 8 beidseitig über die Seitenwände 9 ermöglichen eine Einhandbedienung gleichermaßen für Links- und Rechtshänder. Beispiel 4:In a modification of the previous exemplary embodiments, a turntable 8 is integrated in the rear side 5 of the mobile telephone 1 as an additional input device, as shown in FIG. 4. A grid of the turntable supports controllable line breaks. The arrangement of the turntable 8 in the middle of the back 5 and a slight lateral protrusion of the turntable 8 on both sides over the side walls 9 enable one-handed operation equally for left and right-handers. Example 4:
In Abwandlung zu den vorhergehenden Ausführungsbeispielen ist in die Rückseite 5 des Mobiltelefons 1 ein Koordinatenschieber 10 als zusätzliches Eingabegerät integriert, wie in Fig. 4 dargestellt. Der Koordinatenschieber 10 kann auf der Rückseite 5 sehr leicht mit dem Finger auf einem begrenzten Feld in X- und Y-Richtung bewegt werden. Die Begrenzung des Schieberfeldes 11 des Koordinatenschiebers 10 steht in einem maßstäblichen Verhältnis zum anzusteuernden Display 3. Die Übersetzung der beiden Achsen ist dabei unabhängig voneinander. Die anzuwendenden Übersetzungen ergeben sich aus dem Größenverhältnis von Display 3 zur Fläche des Schieberfeldes 11. Mit diesem zusätzlichen Eingabegerät läßt sich insbesondere in elektronischen Stadtplänen gut navigieren.In a modification of the previous exemplary embodiments, a coordinate slide 10 is integrated into the rear side 5 of the mobile telephone 1 as an additional input device, as shown in FIG. 4. The coordinate slide 10 can be moved on the back 5 very easily with the finger in a limited field in the X and Y directions. The limitation of the slide field 11 of the coordinate slide 10 is in a scale relationship to the display 3 to be controlled. The translation of the two axes is independent of one another. The translations to be used result from the size ratio of display 3 to the area of the slide field 11. This additional input device is particularly easy to navigate in electronic city maps.
Beispiel 5:Example 5:
In Abwandlung zu den vorhergehenden Ausführungsbeispielen ist in die Rückseite 5 des Mobiltelefons 1 ein 3D-Trackpad 12 als zusätzliches Eingabegerät integriert, wie in Fig. 5 darge- stellt.
