Description

Die Erfindung betrifft eine Bedieneinrichtung und ein Kommunikationsgerät, insbesondere ein Mobiltelefon, ein Schnurlostelefon oder einen tragbaren Computer.The invention relates to an operating device and a communication device, in particular a mobile telephone, a cordless telephone or a portable computer.

Die rasante technische Entwicklung auf dem Gebiet der Mobilkommunikation hat in den letzten Jahren zu einer fortschreitenden Miniaturisierung der dabei verwendeten Endgeräte geführt.The rapid technical development in the field of mobile communications has in recent years to a progressive miniaturization of the used terminals guided.

Diese fortschreitende Miniaturisierung der Endgeräte bringt – nicht nur auf dem Gebiet der Mobilkommunikation – erhebliche Probleme hinsichtlich des Bedienkomforts mit sich, weil es aufgrund der kleinen Gehäuseoberflächen der miniaturisierten Endgeräte nicht mehr möglich ist, diese mit einer dem Funktionsumfang der Geräte entsprechenden Anzahl von Tasten zu versehen.This progressive miniaturization of the terminals does not bring only in the field of mobile communications - significant problems regarding the Ease of use with it, because it due to the small housing surfaces of miniaturized devices not possible anymore is, this with a corresponding to the scope of the devices number of Buttons to provide.

Bekannte Lösungen dieses Problems sehen einen so genannten Touchscreen vor, bei dem eine Anzeigeeinrichtung derart mit einer Sensoreinrichtung gekoppelt ist, dass ein berührungssensitves Anzeigefeld entsteht, das eine ortsaufgelöste Detektion von Berührungen der Anzeigeeinrichtung ermöglicht. Dadurch können Anzeigeelemente flexibel auf der Anzeigeeinrichtung dargestellt werden und durch eine Berührung der Anzeigeeinrichtung am Ort der Darstellung der Anzeigeelemente mit einem Eingabeelement – wie beispielsweise einem Finger oder einem Stift (Pen) – ausgewählt werden.Known solutions to this problem see one so-called touch screen, in which a display device such is coupled to a sensor device that a touchsensitves Display field is created, which is a spatially resolved detection of touch allows the display device. Thereby can Display elements flexibly displayed on the display device be and by a touch the display device at the location of the display of the display elements with an input element - like For example, a finger or a pen (Pen) - be selected.

Allerdings führt die zunehmende Miniaturisierung der Endgeräte und die zunehmende Auflösung der Anzeigeeinrichtungen zu dem Nachteil, dass die Anzeigeelemente häufig derart klein auf der Anzeigeeinrichtung dargestellt werden, dass sie nur mehr mit Mühe zu erkennen sind und, insbesondere durch breite Eingabeelemente – wie beispielsweise Finger –, nur noch mit Schwierigkeiten eindeutig auszuwählen sind.However, the increasing miniaturization leads of the terminals and the increasing resolution the display devices to the disadvantage that the display elements often be shown so small on the display device that they just more with difficulty can be seen and, in particular by wide input elements - such as fingers - only are difficult to select with difficulty.

Der Erfindung liegt nun die Aufgabe zugrunde, eine technische Lehre anzugeben, die eine leicht erkennbare Darstellung von Anzeigeelementen insbesondere bei der Verwendung von flächenmäßig kleinen Anzeigeeinrichtungen ermöglicht.The invention is now the task to provide a technical teaching that is easily recognizable Display of display elements, especially in use of small area Display devices allows.

Diese Aufgabe wird durch die Merkmale der unabhängigen Ansprüche gelöst. Vorteilhafte und zweckmäßige Weiterbildungen ergeben sich aus den abhängigen Ansprüchen. Im Rahmen der Erfindung liegen dabei auch Weiterbildungen des Kommunikationsgerätes, die den Weitebildungen der Bedieneinrichtung entsprechen.This task is characterized by the features the independent one claims solved. Advantageous and expedient developments arise from the dependent ones Claims. In the context of the invention are also developments of the communication device, the correspond to the width of the control device.

Die Erfindung basiert demnach auf dem Gedanken, die Position eines Eingabeelementes relativ zu einer Anzeigeeinrichtung zu erfassen und ein Anzeigeelement in Abhängigkeit von der Position des Eingabeelementes in einer Richtung senkrecht zur Ebene der Anzeigeeinrichtung vergrößert darzustellen.The invention is therefore based on the thought, the position of an input element relative to a Detect display device and a display element in dependence from the position of the input element in a direction perpendicular enlarged display to the level of the display device.

Dies ermöglicht ein leichteres Erkennen von Anzeigeelementen und dadurch insbesondere eine komfortablere und zuverlässigere Auswahl von Anzeigeelementen.This allows for easier recognition of display elements and thereby in particular a more comfortable and more reliable Selection of display elements.

Bei der mit einer Sensorreinrichtung gekoppelten Anzeigeeinrichtung kann es sich beispielsweise um einen Touchscreen handeln, der um Sensorelemente zur Detektion des Abstandes zwischen Eingabeelement und Touchscreenoberfäche ergänzt ist.When with a sensor device coupled display device may be, for example, a Touchscreen acting around sensor elements to detect the distance between input element and Touchscreenoberfäche is added.

Bei dem Eingabeelement kann es sich auch um einen Finger, insbesondere eine Fingerspitze oder einen Stift (Pen), insbesondere eine Stiftspitze, handeln. Das Eingabeelement kann auch aktive oder passive Teile der Sensoreinrichtung umfassen.The input element may be also around a finger, especially a fingertip or a Pen, in particular a pen tip act. The input element may also include active or passive parts of the sensor device.

Bei einem Anzeigeelement kann es sich auch um Symbole, Icons, Bilder, Ziffern oder Buchstaben handeln. Ein Anzeigeelement kann aber auch bestimmt sein durch eine bestimmte Fläche, die die Position des Eingabeelementes in Richtung der Ebene der Anzeigeeinrichtung umgibt; beispielsweise durch einen Kreis mit einem bestimmten Radius, dessen Mittelpunkt durch die Position des Eingabeelementes in Richtung der Ebene der Anzeigeeinrichtung bestimmt ist, oder durch eine entsprechende andere Form, wie beispielsweise ein Rechteck.For a display element it can they are also symbols, icons, pictures, numbers or letters. A display element can also be determined by a specific Surface, the position of the input element in the direction of the plane of Surrounding display device; for example, by a circle with a certain radius whose center is determined by the position of the Input element determined in the direction of the level of the display device is, or by a corresponding other form, such as a rectangle.

Weiterbildungen der Erfindung, welche durch aufwändige Untersuchungen an eigens für diesen Zweck geschaffenen Man-Machine-Interface-Simulatoren geschaffen wurden, ermöglichen eine besonders komfortable, insbesondere intuitive, Nutzung der Bedieneinrichtung, insbesondere im Rahmen von Telefonieanwendungen, indem sie eine zuverlässige und/oder komfortable Auswahl von dargestellten Anzeigeelementen auf einer Anzeigeeinrichtung ermöglichen.Further developments of the invention, which by complex Investigations on specially for created for this purpose man-machine interface simulators were created a particularly comfortable, in particular intuitive, use of Operating device, in particular in the context of telephony applications, by having a reliable one and / or comfortable selection of displayed display elements enable on a display device.

1 zeigt als Kommunikationsgerät eine Mobilstation MS, insbesondere ein Mobiltelefon, welche eine Bedieneinrichtung MMI, eine Hochfrequenzeinrichtung HF und eine Prozessoreinrichtung PE enthält. Die Bedieneinrichtung MMI umfasst einen Touchscreen, welcher durch eine mit einer Sensoreinrichtung SEN gekoppelten Anzeigeeinrichtung DPL, beispielsweise mit einem Grafikdisplay, realisiert ist. 1 shows as a communication device, a mobile station MS, in particular a mobile phone, which includes an operating device MMI, a high-frequency device HF and a processor device PE. The control device MMI comprises a Touchscreen, which is realized by a coupled with a sensor device SEN display device DPL, for example, with a graphic display.

Zur Steuerung der Mobilstation MS und insbesondere der Bedieneinrichtung MMI ist eine programmgesteuerte Prozessoreinrichtung PE, wie beispielsweise ein Mikrocontroller vorgesehen, der auch einen Prozessor CPU und eine Speichereinrichtung SPE umfassen kann. Auch die Kopplung der Sensoreinrichtung SEN mit der Anzeigeeinrichtung DPL kann durch die Prozessoreinrichtung realisiert sein.To control the mobile station MS and in particular the operating device MMI is a program-controlled Processor device PE, such as a microcontroller which also includes a processor CPU and a memory device SPE may include. Also, the coupling of the sensor device SEN with the Display device DPL can be realized by the processor device his.

Die Prozessoreinrichtung kann dabei beispielsweise auch durch einen Chipsatz, der mehrere Prozessoren aufweisen kann, realisiert sein, der eigens zur Steuerung einer Bedieneinrichtung oder einer Mobilstation hergestellt worden ist.The processor device can thereby for example, by a chipset, the multiple processors can be realized, which is specifically for controlling a Operating device or a mobile station has been produced.

In der Speichereinrichtung SPE sind auch die Programmdaten, wie beispielsweise die Steuerbefehle oder Steuerprozeduren, die zur Steuerung der Mobilstation und insbesondere der Bedieneinrichtung MMI herangezogen werden, gespeichert.In the memory device SPE are also the program data, such as the control commands or Control procedures used to control the mobile station and in particular the operating device MMI are used stored.

Die unterschiedlichen Komponenten der Prozessoreinrichtung können über ein Bussystem BUS oder Ein-/Ausgabeschnittstellen und gegebenenfalls geeignete Controller untereinander oder mit weiteren Komponenten der Mobilstation Daten austauschen.The different components the processor device can via a Bus system BUS or input / output interfaces and if necessary suitable controllers with each other or with other components exchange data with the mobile station.

Es ist einem Fachmann hinreichend bekannt, zur Steuerung einer Mobilstation bzw. einer Bedieneinrichtung und zur Realisierung bestimmter Funktionen und Anwendungen der Mobilstation diese und weitere Komponenten einer Prozessoreinrichtung und damit die Prozessoreinrichtung programmtechnisch entsprechend einzurichten. Auch ein Touchscreen bzw. die Kopplung einer Anzeigeeinrichtung mit einer beispielsweise kapazitiven Sensoreinrichtung, derart, dass die Position eines Eingabeelementes relativ zur Anzeigeeinrichtung ermittelt wird, an sich ist bekannt, weshalb an dieser Stelle nicht näher darauf eingegangen wird.It is sufficient for a specialist known, for controlling a mobile station or an operating device and to implement certain functions and applications of the mobile station these and other components of a processor device and thus to set up the processor device according to the program. Also a touch screen or the coupling of a display device with a capacitive sensor device, for example, that the position of an input element relative to the display device is determined, in itself is known why not at this point closer to it will be received.

2 zeigt eine Anzeigeeinrichtung DPL, auf der als Anzeigeelement das Zeichen F dargestellt ist. Über dem Zeichen F befindet sich als Eingabeelement ein Stift EE. Durch die (nicht dargestellte) Sensoreinrichtung wird die Position der Spitze des Eingabeelementes in Richtung der Ebene (x,y) der Anzeigeeinrichtung DPL detektiert, indem die Koordinaten x0 und y0 ermittelt werden. Als nächstes zu diesen Koordinaten x0,y0 liegendes Anzeigeelement wird das Zeichen F ermittelt und ausgewählt. Außerdem wird die Position der Spitze des Eingabeelementes in einer Richtung (z) senkrecht zur Anzeigeeinrichtung und somit der Abstand zwischen Eingabeelement und Anzeigeeinrichtung detektiert, indem die Koordinate z0 ermittelt wird. 2 shows a display device DPL, on which as the display element the character F is shown. Above the character F there is an input EE pin. By the (not shown) sensor device, the position of the tip of the input element in the direction of the plane (x, y) of the display device DPL is detected by the coordinates x0 and y0 are determined. Next to these coordinates x0, y0 lying display element, the character F is determined and selected. In addition, the position of the tip of the input element in a direction (z) perpendicular to the display device and thus the distance between the input element and the display device is detected by the coordinate z0 is determined.

Alternativ oder ergänzend zu der Auswahl eines Zeichens F als Anzeigeelement erfolgt gemäß einer Ausführungsvariante der Erfindung in Abhängigkeit von der Position der Spitze des Eingabeelementes in Richtung der Ebene (x,y) der Anzeigeeinrichtung die Auswahl einer kreisförmigen Fläche ANZF, deren Mittelpunkt durch die Position der Spitze des Eingabeelementes in Richtung der Ebene (x,y) der Anzeigeeinrichtung bestimmt ist, als Anzeigeelement.Alternatively or in addition to the selection of a character F as a display element is carried out according to a variant the invention in dependence from the position of the tip of the input element in the direction of Plane (x, y) of the display device, the selection of a circular surface ANZF whose Center point through the position of the tip of the input element in Direction of the level (x, y) of the display device is determined as Display element.

Unterschreitet nun – wie in 3 gezeigt – der Abstand zwischen Eingabeelement und Anzeigeeinrichtung z1 einen Schwellwertabstand zs, so wird das ausgewählte Anzeigeelement F (und/oder alles, was innerhalb der kreisförmigen Fläche ANZF dargestellt ist, wie beispielsweise das Rechteck) vergrößert dargestellt.Falls below now - as in 3 2, the distance between the input element and the display device z1 has a threshold distance zs, the selected display element F (and / or everything that is shown within the circular area ANZF, such as the rectangle) is enlarged.

Ergänzend oder alternativ dazu sieht eine Ausgestaltung der Erfindung vor, dass die Größe der Darstellung, beispielsweise der Zoomfaktor, des Anzeigeelementes F (und/oder von allem, was innerhalb der kreisförmigen Fläche ANZF dargestellt ist) von dem Abstand zwischen Eingabeelement und Anzeigeeinrichtung abhängt, so dass die Größe der Darstellung zumindest innerhalb bestimmter Grenzen mit Verringerung des Abstandes zunimmt .In addition or as an alternative provides an embodiment of the invention that the size of the representation, For example, the zoom factor of the display element F (and / or of everything that is represented within the circular area ANZF) of the distance between input element and display device depends, so that the size of the representation at least within certain limits with reduction of the distance increases.

Berührt nun das Eingabeelement EE die Anzeigeeinrichtung an einer Stelle, die der vergrößerten Darstellung des Anzeigeelementes dient, so wird dadurch das entsprechende Anzeigeelement ausgewählt oder markiert.Touch now the input element EE the display device in one place, the enlarged representation the display element is used, then it becomes the corresponding display element selected or marked.

Eine besondere Ausgestaltung der Erfindung sieht – wie in 4 dargestellt – für den Fall der vergrößerten Darstellung eines Anzeigeelementes F vor, dass benachbarte Anzeigeelemente S,D,G,H durch diese vergrößerte Darstellung überlagert werden.A particular embodiment of the invention provides - as in 4 shown - in the case of the enlarged representation of a display element F before that adjacent display elements S, D, G, H are superimposed by this enlarged representation.

Alternativ zu der überlagerten Darstellung des vergrößerten Anzeigeelementes sieht eine Ausführungsvariante der Erfindung vor, dass die vergrößerte Darstellung des ausgewählten Anzeigeelementes verzerrt entsprechend der vergrößerten Darstellung des Anzeigeelementes mittels einer optischen Linse, insbesondere einer Lupe, erfolgt. Dieses Prinzip ist vereinfacht in 5 dargestellt, die in den Abbildungen von (a) nach (d) ein sich dem Anzeigeelement R näherndes Eingabeelement EE (durch den kleiner werdenden Finger dargestellt) zeigt. Je kleiner der Abstand zwischen Anzeigeeinrichtung und Eingabe element wird, desto größer wird das Anzeigeelement R (und/oder die umgebende Fläche) dargestellt und desto verzerrter werden die das Anzeigeelement R umgebenden Anzeigeelemente dargestellt. Die verzerrte vergrößerte Darstellung eines Anzeigeelementes entspricht dabei in einer Ausführungsvariante der vergrößerten Darstellung durch eine Lupe, wobei die Position des Eingabeelementes in Richtung der Ebene der Anzeigeeinrichtung die Position des Mittelpunktes dieser virtuellen Lupe bestimmt und die Position des Eingabeelementes in einer Richtung senkrecht zur Ebene der Anzeigeeinrichtung den Abstand der virtuellen Lupe von der Anzeigeeinrichtung bestimmt.As an alternative to the superposed representation of the enlarged display element, an embodiment variant of the invention provides that the enlarged representation of the selected display element is distorted in accordance with the enlarged representation of the display element by means of an optical lens, in particular a magnifying glass. This principle is simplified in 5 4, which shows an input element EE (represented by the decreasing finger) approaching the display element R in the illustrations of (a) to (d). The smaller the distance between the display device and input element is, the larger the display element R (and / or the surrounding area) is displayed and the more distorted the display element R surrounding display elements are shown. The distorted enlarged representation of a display element corresponds in one embodiment of the enlarged view through a magnifying glass, wherein the position of the input element in the direction of the plane of the display device determines the position of the center of this virtual magnifying glass and the position of the input element in a direction perpendicular to the plane of the display device determines the distance of the virtual magnifying glass from the display device.

Neben den oben erläuterten Ausführungsvarianten der Erfindung liegt eine Vielzahl weiterer Ausführungsvarianten im Rahmen der Erfindung, welche hier nicht weiter beschrieben werden, aber anhand der erläuterten Ausführungsbeispiele einfach in die Praxis umgesetzt werden können.In addition to the Ausführungsva explained above Variants of the invention is a variety of other embodiments within the scope of the invention, which will not be described further here, but can be easily implemented in practice on the basis of the illustrated embodiments.
