Description

Die Erfindung betrifft ein Verfahren zum Anzeigen visueller Information auf einer Anzeigefläche gemäß dem Oberbegriff des Anspruchs 1. Ein solches Verfahren ist aus den Dokumenten US 5,384,593 und US 5,333,009 bekannt.The invention relates to a method for displaying visual information on a display surface according to the preamble of claim 1. Such a method is known from the documents US 5,384,593 and US 5,333,009 known.

Die Erfindung betrifft weiters ein Computerprogrammprodukt, ein computerlesbares Medium, einen Computer und ein Anzeigesystem.The invention further relates to a computer program product, a computer readable medium, a computer and a display system.

Zwischen 1997 und 2001 haben Augenkrankheiten in Österreich um 30 Prozent zugenommen; international sind ähnliche Zahlen zu beobachten. Vorübergehende Störungen wie das sogenannte "Trockene Auge", auch "office eye syndrome" oder "red eye syndrome" genannt, können im Gegensatz zu tatsächlichen Erkrankungen durch regelmäßiges Training gelindert bzw. verhindert werden, bevor sie zu einer Schädigung des Auges führen. Untersuchungen haben jedoch ergeben, dass das (selbständige) Training kaum, bzw. erst nach Auftreten der Symptome durchgeführt wird - also, wenn es bereits zu Irritationen gekommen ist. Besonders häufig treten Augenbeschwerden, auch als Computer-Vision-Syndrome (CVS) bekannt, am Arbeitsplatz und bei der Autofahrt auf, weil hier die Augen einem ungünstigen Umfeld ausgeliefert sind. Dieses setzt sich aus folgenden Faktoren zusammen: Heizung bzw. Klimaanlage sowie Bildschirmarbeit/konstanter Fokus, wobei diese Faktoren gegenseitig beschleunigend wirken, da beide die Austrocknung der Augen fördern. Erstere trocknen die Luft aus und damit das Umfeld des Auges. Bildschirmarbeit/konstanter Fokus unterbindet zusätzlich das die trockene Luft kompensierende Blinzeln, bei dem das Auge jedes Mal mit einem Tränenfilm überzogen wird und somit feucht bleibt. Fällt die permanente Benetzung aus, wird die Augenoberfläche trocken, bemerkbar durch Brennen, Jucken, Rötung, Ziehschmerz des Auges sowie Kopfschmerzen. Die für Bildschirmarbeit/konstanten Fokus notwendige Konzentration bewirkt, dass wir die Augen ungewöhnlich lange offen halten ("starren") und bei anfänglicher Ermüdung diese Haltung auch noch verkrampfen. Zusätzlich wird das Auge durch die lange konstante Strahlung des Bildschirms langsam geblendet.Between 1997 and 2001, eye diseases in Austria increased by 30 percent; internationally, similar numbers can be observed. Temporary disorders such as the so-called "dry eye", also called "office eye syndrome" or "red eye syndrome", can be alleviated or prevented, in contrast to actual illnesses by regular training, before they lead to damage to the eye. Studies have shown, however, that the (independent) training hardly, or only after the onset of symptoms is carried out - so, if it has already come to irritation. Eye problems, also known as computer vision syndromes (CVS), are particularly common in the workplace and during car trips because the eyes are exposed to an unfavorable environment. This consists of the following factors: heating or air conditioning and screen work / constant focus, whereby these factors have an accelerating effect, since both promote the drying of the eyes. The former dry out the air and thus the environment of the eye. Screen work / constant focus also eliminates the dry air compensating blink, where the eye is covered with a tear film every time, leaving it moist. If the permanent wetting fails, the eye surface becomes dry, noticeable by burning, itching, redness, drawing pain of the eye and headache. The concentration required for screen work / constant focus causes us to keep our eyes open for an unusually long time ("staring") and, at the beginning of fatigue, also makes that posture cramp. In addition, the eye is slowly blinded by the long constant radiation of the screen.

Außer bei der Bildschirmarbeit treten die beschriebenen Irritationen des Auges auch beim angestrengten Lesen oder beim Betrachten von Projektionen auf. Es gibt auch in der Industrie viele Arbeitsplätze, wo konzentriertes Schauen bei konstantem Fokus erforderlich ist, z.B. bei visueller Inspektion von in Fertigungslinien hergestellten Industileprodukten. Auf Grund der Entwicklung in der Kraftfahrzeugindustrie werden in naher Zukunft in KFZs Head-Up Displays (in der Folge HUD) serienmäßig installiert werden. Zwar entfällt bei HUD's die Reaktionszeit des Umfokussierens von Fern- auf Nahsicht und umgekehrt, woraus eine kürzere Reaktionszeit des Fahrers resultiert; der permanente Blick auf die Straße bzw. auf die mittels HUD eingeblendete Information führt jedoch ebenfalls zu den oben beschriebenen Symptomen.Apart from the work on the screen, the described irritations of the eye also occur during strenuous reading or when viewing projections. There are also many jobs in the industry where concentrated vision is required with constant focus, for example, visual inspection of in-line manufactured industrial products. Due to the development in the automotive industry, head-up displays (hereinafter HUD) will be installed as standard in motor vehicles in the near future. Although the response time of the refocusing from distance to near vision and vice versa is omitted in HUDs, resulting in a shorter reaction time of the driver; the permanent view of the street However, the information displayed by means of HUD likewise leads to the symptoms described above.

Aus der veröffentlichten US-Patentanmeldung US 2003/0218721 A1 sind ein System und ein Verfahren zur optimierten Betrachtung von Computermonitoren bekannt, die darauf abzielen, die Augenbelastung des Betrachters zu minimieren. Das Verfahren umfasst das Ermitteln einer optimalen Entfernung zwischen dem Computermonitor und dem Betrachter und das Überwachen der Entfernung zwischen dem Computermonitor und dem Betrachter während der Benützung des Computers. Gemäß dem Verfahren wird der Benutzer benachrichtigt, wenn er die ermittelte optimale Entfernung nicht einhält. Weiters können verschiedene Augentests unter Zuhilfenahme des Computermonitors durchgeführt werden.From the published US patent application US 2003/0218721 A1 For example, there are known a system and method for optimized viewing of computer monitors aimed at minimizing eye strain on the viewer. The method includes determining an optimal distance between the computer monitor and the viewer and monitoring the distance between the computer monitor and the viewer while using the computer. According to the method, the user is notified if he does not comply with the determined optimal distance. Furthermore, various eye tests can be carried out with the aid of the computer monitor.

Durch dieses bekannte System und Verfahren wird ansatzweise jedoch nur das spezifische Problem gelöst, dass für ein Display mit bestimmter Bildschirmdiagonale eine korrespondierende optimale Distanz des Betrachters vom Bildschirm eingehalten werden sollte. Wenn der Betrachter aber diese empfohlene Distanz einhält, besteht für ihn umso mehr die Gefahr von Augenirritation durch gleichförmige Fokussierung des Auges. Weiterhin ungelöst bleibt das Problem, dass konzentrierte Bildschirmarbeit und der konstante Fokus des Auges eines Betrachters auf den Bildschirm dazu führen, dass das zur Benetzung des Auges mit Tränenflüssigkeit so wichtige Blinzeln unterbleibt und somit die Augenoberfläche austrocknet.By this known system and method, however, only the specific problem is loosely solved that for a display with a certain screen diagonal a corresponding optimal distance of the viewer should be observed by the screen. However, if the viewer adheres to this recommended distance, he is all the more likely to suffer from eye irritation due to uniform focusing of the eye. Still unresolved remains the problem that concentrated screen work and the constant focus of the eye of a viewer on the screen cause that for wetting the eye with tears liquid so important omitted, thus drying out the eye surface.

Es besteht daher nach wie vor das Bedürfnis, eine Lösung anzubieten, wie die bekannten Augenreizungen verringert oder optimalerweise sogar ganz unterbunden werden können, indem dafür gesorgt wird, dass das Auge durch Blinzeln in ausreichender Frequenz mit einem Tränenfilm überzogen wird und somit feucht bleibt.There is therefore still the need to offer a solution, as the known eye irritation can be reduced or optimally even completely prevented by making sure that the eye is covered by blinking in sufficient frequency with a tear film and thus remains moist.

Die Erfindung löst dieses Problem durch Bereitstellen eines Verfahrens und eines Systems zum Anzeigen visueller Information auf einer Anzeigefläche, mit den kennzeichnenden Merkmalen des Anspruchs 1. Das erfindungsgemäße Verfahren unterscheidet sich von den aus den Dokumenten US 5,384,593 und US 5,333,009 bekannten Verfahren dadurch, dass mittels eines Betriebssystems mehrere übereinanderliegende Anzeigeebenen auf der Anzeigefläche dargestellt werden, wobei als oberste Anzeigeebene ein transparenter Bereich vorgesehen wird, der für die Subliminal-Zeitdauer gemäß dem Anzeigeparameter in einen nicht vollständig transparenten Modus umgeschaltet wird.The invention solves this problem by providing a method and a system for displaying visual information on a display surface, with the characterizing features of claim 1. The method according to the invention differs from the documents US 5,384,593 and US 5,333,009 known methods in that by means of an operating system several superimposed display levels are displayed on the display surface, being provided as the top display level, a transparent area, which is switched for the Subliminal period according to the display parameters in a non-transparent mode.

Die gemäß der vorliegenden Erfindung gelöste objektive Aufgabe ist in der vereinfachten Durchführung einer subliminalen Veränderung eines Anzeigeparameters durch Ausnutzung der Möglichkeiten des Betriebssystems zu sehen.The objective task solved according to the present invention is to see the simplified implementation of a subliminal change of a display parameter by exploiting the capabilities of the operating system.

Gemäß der Erfindung wird das durch konzentriertes Schauen, wie z.B. bei der Bildschirmarbeit, oder durch gleichförmige Fokussierung des Auges vergessene bzw. unbewusst unterdrückte Blinzeln fremdgesteuert ausgelöst, indem wiederholt in zumindest einem Bereich der Anzeigefläche für eine Subliminal-Zeitdauer, die unterhalb der menschlichen Wahrnehmungsgrenze liegt, ein Anzeigeparameter verändert wird. Das Bestechende an dieser Idee ist, dass ein Betrachter von dieser Fremdauslösung des Blinzelvorganges an ihm nichts bemerkt, da sie sich im subliminalen Bereich abspielt, das heißt, nur für eine so kurze Dauer, dass das menschliche Gehirn diese Veränderung des Anzeigeparameters nicht bewusst wahrnimmt. Sehr wohl reagiert aber das Auge immer wieder (wenn auch nicht notwendigerweise jedes Mal) auf diese Veränderung des Anzeigeparameters und löst das Blinzeln aus. Ebenso wenig wie der Mensch im entspannten Zustand bemerkt, dass er in regelmäßigen Abständen blinzelt, führt die erfindungsgemäß fremdgesteuerte Auslösung des Blinzelvorganges nicht zu einem unangenehmen Gefühl, wie es beispielsweise ausgelöst wird, wenn die Augen durch grelles Licht so geblendet werden, dass die Augenlider unwillkürlich geschlossen werden. Vielmehr bewirkt das erfindungsgemäß fremdgesteuert ausgelöste Blinzeln ein verbessertes Wohlbefinden des Betrachters, da das Augenblinzeln harmonisch in regelmäßigen Intervallen vor sich geht und das Auge somit immer ausreichend befeuchtet ist und in weiterer Folge die Konzentration verbessert und die Arbeit erleichtert.According to the invention, blinking forgotten by concentrated vision, such as at screen work, or by uniformly focusing the eye, is externally triggered by repeatedly repeating in at least a portion of the display area for a subliminal period of time that is below the human perception limit , a display parameter is changed. The interesting thing about this idea is that a viewer does not notice anything about this triggering of the blinking process on him because they are in the picture subliminal range, that is, for a short duration only, so that the human brain does not consciously perceive this change in the display parameter. But the eye reacts very often (though not necessarily every time) to this change in the display parameter and triggers blinking. As little as the human noticed in the relaxed state that he blinks at regular intervals, the inventively externally controlled triggering the Blinzelvorganges does not lead to an unpleasant sensation, as it is triggered, for example, when the eyes are blinded by bright light so that the eyelids involuntarily getting closed. On the contrary, the blinking triggered according to the invention causes an improved well-being of the observer, since the blinking of the eyes proceeds harmoniously at regular intervals and the eye is thus always sufficiently moistened and subsequently improves the concentration and facilitates the work.

Es sei erwähnt, dass es seit langem bekannt ist, so genannte "subliminale Information", das ist Information, deren Zeitdauer unter der Erkennungsfähigkeit des menschlichen Gehirns liegt, in Filme, Videos oder Fernsehsignale einzublenden. Es ist erwiesen, dass ein Betrachter die subliminale Information zwar nicht bewusst wahrnehmen kann, unterbewusst aber dennoch darauf reagiert. Dieser Effekt wird beispielsweise dazu genützt, um Personen eine Botschaft zu suggerieren, z.B. die Botschaft "Iss weniger". Dieser Effekt des Einspielens von subliminaler Information hat mit der vorliegenden Erfindung jedoch nicht das Geringste zu tun. Gemäß der Erfindung wird nicht die angezeigte Information verändert, beeinflusst oder durch andere Information ersetzt, sondern ein Anzeigeparameter in einem solchen Ausmaß verändert, dass dadurch eine optimale Lidbewegung erreicht werden kann, durch die die Benetzung des Auges sichergestellt und Ermüdungs- und Entzündungserscheinungen vorgebeugt wird. Die Anzeige visueller Information wird dadurch wesentlich augenschonender als dies bei herkömmlichen Anzeigesystemen der Fall ist und führt somit auch allgemein zu einem verstärkten Wohlbefinden des Betrachters.It should be noted that it has long been known, so-called "subliminal information", that is information whose duration is below the human brain's ability to recognize, to be superimposed on films, videos or television signals. It has been proven that a viewer can not consciously perceive the subliminal information, but unconsciously reacts to it. This effect is used, for example, to suggest a message to people, e.g. the message "Eat less". However, this effect of incorporating subliminal information has nothing to do with the present invention. According to the invention, the displayed information is not changed, influenced or replaced by other information, but changes a display parameter to such an extent that optimal lid movement can be achieved thereby ensuring the wetting of the eye and preventing fatigue and inflammatory phenomena. The display of visual information is thereby much easier on the eyes than is the case with conventional display systems and thus generally leads to an increased well-being of the viewer.

Gemäß der Erfindung wird das Blinzeln des Auges ferngesteuert, indem ein Anzeigeparameter in zumindest einem Bereich der Anzeigefläche für eine Subliminal-Zeitdauer, die unterhalb der menschlichen Wahrnehmungsgrenze liegt, verändert wird. Vorzugsweise wird als zu ändernder Anzeigeparameter Anzeigehelligkeit, -farbe, -beleuchtung, -kontrast, -fokus, -frequenz oder Ein/Ausschalten der Anzeige ausgewählt. Es hat sich nämlich gezeigt, dass damit eine Blinzel-Bewegung herbeigeführt werden kann, die der Betrachter der Anzeigefläche in keiner Weise als unangenehm empfindet und durch die er in seiner Tätigkeit nicht abgelenkt oder eingeschränkt wird.According to the invention, the blinking of the eye is remotely controlled by changing a display parameter in at least a portion of the display area for a subliminal period of time that is below the human perception limit. Preferably, display brightness, color, lighting, contrast, focus, frequency or on / off display is selected as the display parameter to be changed. It has been shown that it can be brought about a Blinzel movement that feels the viewer of the display surface in any way as unpleasant and by which he is not distracted or restricted in its activity.

Die Subliminal-Zeitdauer, innerhalb der der Mensch Änderungen eines Anzeigeparameters nicht bewusst wahrnehmen kann, schwankt von Individuum zu Individuum und auch mit der Tagesverfassung etc. Es hat sich jedoch erwiesen, dass die Subliminal-Zeitdauer in jedem Fall kurz genug ist, wenn sie 0,06 s nicht überschreitet. Optional ist auch vorgesehen, dass der Betrachter die Subliminalzeitdauer verstellen kann, um sie an seine eigene Empfindsamkeit optimal anzupassen.The Subliminal period of time, during which the human being can not consciously perceive changes in a display parameter, varies from individual to individual and also with the constitution of the day, etc. However, it has been proven that the subliminal period is always short enough when it reaches 0 , Does not exceed 06 s. Optionally, it is also provided that the viewer can adjust the Subliminalzeitdauer to optimally adapt to his own sensitivity.

In einer Fortbildung der Erfindung ist auch vorgesehen, dass in Zeitintervallen, die größer als die Trigger-Intervalle sind, der Anzeigeparameter in zumindest einem Bereich der Anzeigefläche für eine, optional einstellbare, Supraliminal-Zeitdauer, die oberhalb der menschlichen Wahrnehmungsgrenze liegt, verändert wird. Dadurch gewinnt der Benutzer die Sicherheit, dass das Verfahren abgearbeitet wird und es kommt auch zu einer bewussten Erinnerung des Benutzers an die Wirksamkeit und Wirkungsweise.In a further development of the invention, it is also provided that, at time intervals which are greater than the trigger intervals, the display parameter is changed in at least one area of the display area for an optionally adjustable supraliminal time duration which is above the human perceptual limit. This gives the user the certainty that the procedure will be carried out and it also comes to a conscious reminder of the user's effectiveness and effect.

Das Trigger-Intervall definiert, in welchen Zeitabständen die Veränderung des Anzeigeparameters durchgeführt wird. In Versuchen hat sich ein Trigger-Intervall zwischen 5 und 20 s als günstig für eine ausreichende Benetzung des Auges mit Tränenflüssigkeit erwiesen. Um eine individuelle Anpassung an die persönlichen Vorlieben und Bedürfnisse eines Betrachters zu ermöglichen, erweist es sich als zweckmäßig, wenn das Trigger-Intervall durch den Betrachter der Anzeigefläche, oder durch einen Zufallsgenerator o. dergl. auf einen Wert, der konstant gehalten wird oder zufällig variiert wird, eingestellt werden kann. In weiterer Ausgestaltung der Erfindung ist auch vorgesehen, das Trigger-Intervall gemäß einem Werteprofil einzustellen, welches Profil beispielsweise ein Tagesprofil oder ein an die Umgebungshelligkeit angepasstes Profil sein kann. Damit das Trigger-Intervall nicht auf so extreme Werte verstellt wird, dass die dadurch veranlasste Blinzelfrequenz zu hoch und somit störend, oder zu niedrig und somit wirkungslos ist, ist weiters vorgesehen, die Variierbarkeit des Trigger-Intervalls nur innerhalb vorgegebener Grenzen zu ermöglichen.The trigger interval defines at which intervals the change of the display parameter is performed. In experiments, a trigger interval between 5 and 20 s has proven to be favorable for a sufficient wetting of the eye with tear fluid. In order to allow an individual adaptation to the personal preferences and needs of a viewer, it proves useful if the trigger interval by the viewer of the display area, or by a random number generator o. The like. To a value that is kept constant or random is varied, can be adjusted. In a further embodiment of the invention, it is also provided to set the trigger interval according to a value profile, which profile may be, for example, a daily profile or a profile adapted to the ambient brightness. So that the trigger interval is not adjusted to such extreme values that the Blinzelfrequenz thereby induced too high and thus disturbing, or too low and thus ineffective, is further provided to allow the variability of the trigger interval only within predetermined limits.

In jenen Fällen, in denen die Anzeigefläche in ein Display integriert ist, hat es sich aufgrund einfacher Realisierung als günstig erwiesen, wenn das Verändern des Anzeigeparameters durch Verändern der Ansteuerung des Display erfolgt.In those cases in which the display area is integrated in a display, it has proven to be favorable due to simple implementation, if the changing of the display parameter by changing the control of the display.

Die Anzeigefläche kann aber auch eine Projektionsfläche oder eine mit der visuellen Information versehene Trägerfläche, wie z.B. eine Druckschrift, sein. Als Anzeigefläche ist aber beispielsweise auch eine von einer Bedienperson visuell zu inspizierende Oberfläche eines Gegenstandes, insbesondere Industrieproduktes, zu verstehen. In den genannten Fällen kann die Anzeigefläche selbst meist nicht direkt verändert werden, sondern sie ergibt sich durch Bestrahlung mit natürlichem oder Fremdlicht. Um das erfindungsgemäße Verfahren jedoch auch in diesen Fällen durchführen zu können, ist vorgesehen einen Anzeigeparameter der Anzeigefläche durch das Bestrahlen der Anzeigefläche mit Licht aus einer Lichtquelle zu verändern, d.h. die Trägerfläche bzw. den Gegenstand für eine Subliminal-Zeitdauer mit Licht aus der Lichtquelle zu bestrahlen.However, the display surface may also be a projection surface or a support surface provided with the visual information, such as a printed document. As a display surface but is for example a to be visually inspected by an operator surface of an object, in particular industrial product to understand. In the cases mentioned the display surface itself can usually not be changed directly, but it results from irradiation with natural or extraneous light. However, in order to be able to carry out the method according to the invention also in these cases, it is provided to change a display parameter of the display surface by irradiating the display surface with light from a light source, ie the carrier surface or the object for a subliminal period with light from the light source irradiate.

Versuche haben ergeben, dass ein Betrachter selten eine gesamte Anzeigefläche betrachtet, sondern sich in seiner Betrachtung auf spezifische Bereiche der Anzeigefläche konzentriert, die seine Aufmerksamkeit momentan anziehen. Solche Bereiche umfassen beispielsweise Bereiche der Anzeigefläche, in denen sich ein Cursor, ein Mauszeiger, ein Eingabefeld, ein aktives Bildschirmfenster oder ein anderer die Aufmerksamkeit des Betrachters hervorrufender Indikator befinden. Es kann beispielsweise aber auch durch Messungen, wie Iriserkennung, herausgefunden werden, auf welchen Bereich einer Anzeigefläche sich die Konzentration eines Betrachters richtet. Die Erfinder haben erkannt, dass es für die Zwecke der Erfindung genügt, wenn ein Anzeigeparameter nur in einem solchen Bereich der Anzeigefläche verändert wird, auf den sich die momentane Aufmerksamkeit des Betrachters richtet. Die Veränderung eines Anzeigeparameters nur in einem Teilbereich der Anzeigefläche ist oftmals technisch einfacher realisierbar als die Veränderung in der gesamten Anzeigefläche.Experiments have shown that a viewer rarely looks at an entire display area, but focuses his attention on specific areas of the display area that are currently attracting his attention. Such areas include, for example, areas of the display area in which a cursor, a mouse pointer, an input field, an active screen window or another indicator that attracts the attention of the observer are located. However, it can also be found, for example by measurements, such as iris recognition, on which area of a display surface the concentration of a viewer is directed. The inventors have realized that, for the purposes of the invention, it suffices if a display parameter is changed only in such a region of the display area on which the current attention of the viewer is directed. The change of a display parameter only in a partial area of the display area is often technically easier to implement than the change in the entire display area.

Das erfindungsgemäße Verfahren eignet sich vorzüglich zur Implementierung mittels eines Computers, wobei verschiedene Ansätze gewählt werden können. Wenn beispielsweise das Verfahren in einem Computer abgearbeitet wird, der ein Betriebssystem aufweist, das die Darstellung mehrerer übereinanderliegender Anzeigeebenen auf einer Anzeigefläche erlaubt, so kann als oberste Anzeigeebene ein transparenter Bereich vorgesehen werden, der für die Subliminal-Zeitdauer gemäß dem Anzeigeparameter in einen nicht vollständig transparenten Modus umgeschaltet wird. Wenn ein solcher Computer weiters zur Darstellung von Anzeigefenstern ausgebildet ist, kann ein transparentes Fenster über zumindest einen Bereich der visuellen Information gelegt und das transparente Fenster für die Subliminal-Zeitdauer gemäß dem Anzeigeparameter in einen nicht vollständig transparenten Modus umgeschaltet werden. In wiederum einer alternativen Ausführungsform des erfindungsgemäßen Verfahrens in einem Computer mit einem Betriebssystem, das zur Darstellung von mehreren Anzeigefenstern ausgebildet ist, wovon ein Anzeigefenster als aktives Anzeigefenster auswählbar ist, auf das Benutzereingaben wirken, kann ein Anzeigeparameter in dem aktiven Fenster verändert werden. In wiederum einer alternativen Ausgestaltung der Erfindung, wenn sie in einem Computer mit einem Betriebssystem implementiert ist, das die Darstellung mehrerer übereinanderliegender Anzeigefenster auf einer Anzeigefläche erlaubt, kann erfindungsgemäß die Veränderung eines Bereiches der Anzeigefläche durch ein für die Subliminal-Zeitdauer eingeblendetes Fenster durchgeführt werden, das durch den Anzeigeparameter vorgegebene Anzeigeeigenschaften aufweist.The inventive method is particularly suitable for implementation by means of a computer, wherein different approaches can be selected. For example, if the method is run in a computer having an operating system that allows the display of multiple superimposed display levels on a display area, then a transparent area can be provided as the uppermost display level, which is not complete for the subliminal period according to the display parameter transparent mode is switched. If such a computer is further adapted to display display windows, a transparent window may be overlaid over at least a portion of the visual information and the transparent subliminal window may be switched to a non-transparent mode in accordance with the display parameter. In yet an alternative embodiment of the method according to the invention in a computer with an operating system which is designed to display a plurality of display windows, of which one display window is selectable as the active display window on which user inputs act, a display parameter in the active window can be changed. In yet an alternative embodiment of the invention, when used in a computer with an operating system is implemented, which allows the display of multiple superimposed display window on a display surface, according to the invention, the change of a portion of the display area can be performed by a hidden for the subliminal time window having display properties predetermined by the display parameters.

Zur Lösung der erfindungsgemäßen Aufgabe ist bei einem Computerprogrammprodukt, das zum Anzeigen visueller Information auf einer Anzeigefläche geeignet ist, gemäß der Erfindung vorgesehen, dass das Computerprogrammprodukt direkt in einen Speicher eines Computers ladbar ist und Softwarecodeabschnitte umfasst, wobei mit dem Computer das Verfahren gemäß der Erfindung abgearbeitet werden kann, wenn das Computerprogrammprodukt auf dem Computer abgearbeitet wird. Das Computerprogrammprodukt kann auf einem computerlesbaren Medium gespeichert sein.In order to achieve the object according to the invention, in a computer program product suitable for displaying visual information on a display surface according to the invention, the computer program product can be loaded directly into a memory of a computer and comprises software code sections, with the computer the method according to the invention can be processed when the computer program product is executed on the computer. The computer program product may be stored on a computer readable medium.

Zur Lösung der erfindungsgemäßen Aufgabe ist bei einem Computer gemäß der Erfindung vorgesehen, dass der Computer eine Recheneinheit und einen internen Speicher aufweist und das Computerprogrammprodukt gemäß dem vorstehend angeführten Absatz abarbeitet.In order to achieve the object according to the invention, it is provided in a computer according to the invention that the computer has an arithmetic unit and an internal memory and processes the computer program product according to the above-mentioned paragraph.

Die vorliegende Erfindung umfasst auch ein Anzeigesystem mit einer Anzeige und zumindest einer Anzeigeeinrichtung, die ein Bild auf einer Anzeigefläche der Anzeige darstellt. Erfindungsgemäß wirken auf die Anzeigeeinrichtung Anzeigeveränderungs-Mittel, die dazu ausgebildet sind, in Trigger-Intervallen einen Anzeigeparameter in zumindest einem Bereich der Anzeigefläche für eine Subliminal-Zeitdauer, die unterhalb der menschlichen Wahrnehmungsgrenze liegt, zu verändern. Der Anzeigeparameter ist vorzugsweise aus Anzeigehelligkeit, -farbe, -beleuchtung, -kontrast, -fokus, -frequenz oder Ein/Ausschalten der Anzeige ausgewählt. Wie weiter oben bereits erwähnt schwankt die Subliminal-Zeitdauer von Individuum zu Individuum und auch über den Tagesverlauf. Vorzugsweise wird die Subliminal-Zeitdauer auf maximal 0,06 Sekunden festgelegt, da Versuche ergeben haben, dass bei diesem Wert die Erfindung für jedermann gute Ergebnisse liefert, wobei, wie gesagt, im Einzelfall auch längere Zeitdauern brauchbar sind. Um optimale Ergebnisse für die unterschiedlichen individuellen Empfindsamkeiten zu erzielen, ist vorgesehen, dass die Subliminal-Zeitdauer einstellbar ist. Zur Anpassung an die unterschiedlichen individuellen Vorlieben und Bedürfnisse kann auch vorgesehen sein, das Trigger-Intervall durch einen Benutzer oder einen Zufallsgenerator auf einen Wert oder ein Werteprofil einstellbar zu machen, wobei zur Verhinderung unerwünschter Ergebnisse vorzugsweise die Variierbarkeit des Trigger-Intervalls innerhalb vorgegebener Grenzen liegt. Um zu starke Gleichförmigkeit bei der subliminal kurzen Veränderung eines Anzeigeparameters zu verhindern, die unter Umständen den Effekt des fremdgesteuerten Hervorrufens von Blinzeln verringern könnte, ist in einer Fortbildung des erfindungsgemäßen Anzeigesystems vorgesehen, dass die Position und/oder Größe des Bereichs der Anzeigefläche, der verändert wird, variierbar ist. Bei der Variierung der Position und/oder Größe des Bereiches kann auch auf die technische Leistungsfähigkeit der Anzeigeveränderungs-Mittel Bedacht genommen werden.The present invention also includes a display system having a display and at least one display device that displays an image on a display surface of the display. According to the invention, the display device has display modification means which are designed to change a display parameter in trigger intervals in at least one area of the display area for a subliminal period which is below the human perception limit. The display parameter is preferably selected from the display brightness, color, illumination, contrast, focus, frequency, or on / off of the display. As mentioned earlier, the Subliminal period of time varies from individual to individual and also over the course of the day. Preferably, the Subliminal period of time is set to a maximum of 0.06 seconds, since experiments have shown that at this value, the invention provides good results for anyone, which, as I said, in individual cases, even longer periods of time are useful. In order to achieve optimal results for the different individual sensitivities, it is provided that the Subliminal period is adjustable. To adapt to the different individual preferences and needs can also be provided to make the trigger interval by a user or a random generator to a value or a value profile adjustable, preferably to prevent undesirable results, the variability of the trigger interval is within predetermined limits , To prevent excessive uniformity in the subliminally short change of a display parameter, which may affect the effect of the extraneous In an embodiment of the display system according to the invention, it is provided that the position and / or size of the area of the display area which is changed can be varied. When varying the position and / or size of the area, consideration may also be given to the technical performance of the display modification means.

Die Erfindung wird nun anhand von nicht einschränkenden Ausführungsbeispielen unter Bezugnahme auf die Zeichnungen näher erläutert. In den Zeichnungen zeigen Fig. 1 ein Blockschaltbild eines erfindungsgemäßen Anzeigesystems 1, Fig. 2 eine Anzeigefläche zur Erläuterung einer Ausführungsform des erfindungsgemäßen Verfahrens, Fig. 3 eine Anzeigefläche zur Erläuterung einer weiteren Ausführungsform des erfindungsgemäßen Verfahrens, Fig. 4 schematisch ein Anzeigensystem, bei dem die Anzeigefläche als Projektionsfläche ausgebildet ist, und Fig. 5 ein weiteres erfindungsgemäßes Anzeigensystem, bei dem die Anzeigefläche durch eine visuelle Information enthaltende Trägerfläche definiert ist.The invention will now be described by way of non-limiting embodiments with reference to the drawings. In the drawings show Fig. 1 a block diagram of a display system 1 according to the invention, Fig. 2 a display surface for explaining an embodiment of the method according to the invention, Fig. 3 a display area for explaining a further embodiment of the method according to the invention, Fig. 4 schematically a display system in which the display surface is designed as a projection surface, and Fig. 5 a further display system according to the invention, wherein the display surface is defined by a support surface containing visual information.

Fig. 1 zeigt ein Blockschaltbild eines erfindungsgemäßen Anzeigesystems 1. Das Anzeigesystem 1 umfasst ein Display 2 mit einer Anzeigefläche 3 zum Anzeigen von visueller Information 9 bzw. von Bildern, wobei diese beiden Begriffe weit auszulegen sind und jede Form von Text, Grafik oder sonstiger auf der Anzeigefläche darstellbarer Information umfassen. Obwohl in Fig. l das Display als Bildschirm dargestellt ist, ist es nicht darauf beschränkt, sondern umfasst alle Arten von Displays, wie z.B. Elektrolumineszenz-Displays, Vakuumfluoreszenz-Displays, Plasma-Displays, Kathodenstrahlröhren, LCDs, Head-Up Displays, aber auch Projektionsgeräte, Videobeamer und dergleichen. Das Display 2 wird von einer Anzeigeeinrichtung 4 angesteuert, die die entsprechende Ansteuerung S zur Darstellung der visuellen Information 9 sowie Anzeigeparameter P an das Display liefert, mit welchen Anzeigeparametern P Anzeigeeigenschaften der Anzeigefläche festgelegt werden. Die Anzeigeparameter P umfassen Anzeigehelligkeit, -farbe, -beleuchtung, -kontrast, -fokus, -frequenz oder dergleichen. Erfindungsgemäß umfasst das Anzeigesystem 1 weiters auf die Anzeigeeinrichtung 4 wirkende Anzeigeveränderungs-Mittel 5, die dazu ausgebildet sind, in Trigger-Intervallen einen Anzeigeparameter P in zumindest einem Bereich der Anzeigefläche 3 für eine Subliminal-Zeitdauer, die unterhalb der menschlichen Wahrnehmungsgrenze liegt, zu verändern. Fig. 1 shows a block diagram of a display system according to the invention 1. The display system 1 comprises a display 2 with a display surface 3 for displaying visual information 9 or images, these two terms are interpreted broadly and any form of text, graphics or other representable on the display surface Information include. Although the display is shown as a screen in FIG. 1, it is not limited thereto, but encompasses all types of displays, such as electroluminescent displays, vacuum fluorescent displays, plasma displays, cathode ray tubes, LCDs, head-up displays, but also Projection devices, video beamer and the like. The display 2 is controlled by a display device 4, which supplies the corresponding control S for displaying the visual information 9 and display parameter P to the display, with which display parameters P display properties of the display surface are determined. The display parameters P include display brightness, color, lighting, contrast, focus, frequency, or the like. According to the invention, the display system 1 further comprises display change means 5 acting on the display device 4, which are designed to change a display parameter P in trigger intervals to at least a portion of the display surface 3 for a subliminal time duration that is below the human perception limit ,

Die Erfinder haben nämlich erkannt, dass durch konzentriertes Schauen, wie z.B. bei der Bildschirmarbeit, oder durch gleichförmige Fokussierung des Auges vergessenes bzw. unbewusst unterdrücktes Blinzeln fremdgesteuert ausgelöst werden kann, indem wiederholt in zumindest einem Bereich der Anzeigefläche 3 ein Anzeigeparameter verändert wird, wobei diese Veränderung nur für die genannte Subliminal-Zeitdauer, die unterhalb der menschlichen Wahrnehmungsgrenze liegt, auftreten muss. Das Bestechende an dieser Idee ist es, dass ein Betrachter von dieser Fremdauslösung des Blinzelvorganges an ihm nichts bemerkt, da sie sich im subliminalen Bereich abspielt, in der das menschliche Gehirn diese Veränderung des Anzeigeparameters noch nicht bewusst wahrnimmt. Sehr wohl reagiert aber das Auge auf diese Veränderung des Anzeigeparameters und löst wie erwünscht das Blinzeln aus. Der Betrachter bemerkt dieses fremdausgelöste Blinzeln nicht, ebenso wie der Mensch allgemein im entspannten Zustand nicht bemerkt, dass er in regelmäßigen Abständen blinzelt. Daher führt dieses erfindungsgemäß fremdgesteuerte Auslösen des Blinzelvorganges auch nicht zu einem unangenehmen Gefühl beim Betrachter der Anzeigefläche 3, sondern steigert vielmehr das Wohlbefinden des Betrachters, da das Augenblinzeln harmonisch in regelmäßigen Intervallen vor sich geht und das Auge somit immer ausreichend befeuchtet ist, wodurch Augenirritationen verlässlich verhindert werden und das so genannte "red eye syndrome" ausgeschaltet wird. Durch die verringerte Augenbelastung stellt sich oftmals auch eine entspanntere Körperhaltung des Betrachters ein, was insbesondere für Bildschirmarbeitsplätze sehr wichtig ist.The inventors have in fact recognized that by concentrated looking, such as in the screen work, or by uniform focusing of the eye forgotten or unconsciously suppressed blinking can be triggered externally controlled by a display parameter is repeatedly changed in at least one area of the display surface 3, this change must occur only for the said subliminal time period, which is below the human perception limit. The interesting thing about this idea is that a viewer does not notice anything about this triggering of the blinking process on him, since it takes place in the subliminal range, in which the human brain does not consciously perceive this change of the display parameter. But the eye reacts very well to this change of the display parameter and triggers the blinking as desired. The viewer does not notice this externally triggered blinking, just as people generally do not notice in a relaxed state that they are blinking at regular intervals. Therefore, this inventively externally controlled triggering of the Blinzelvorganges also does not lead to an unpleasant feeling in the viewer of the display surface 3, but rather enhances the well-being of the viewer, since the Augenblinkeneln harmoniously at regular intervals is going on and the eye is thus always sufficiently moistens, making eye irritation reliable prevented and the so-called "red eye syndrome" is turned off. Due to the reduced eye strain is often a relaxed posture of the viewer, which is very important especially for computer workstations.

Die Subliminal-Zeitdauer, innerhalb der der Mensch Änderungen eines Anzeigeparameters nicht bewusst wahrnehmen kann, schwankt von Individuum zu Individuum und auch mit der Tagesverfassung etc. Es hat sich jedoch erwiesen, dass die Subliminal-Zeitdauer in jedem Fall kurz genug ist, wenn sie 0,06 s nicht überschreitet. Optional ist auch vorgesehen, dass der Betrachter die Subliminalzeitdauer verstellen kann, um sie an seine eigene Empfindsamkeit optimal anzupassen.The Subliminal period of time, during which the human being can not consciously perceive changes in a display parameter, varies from individual to individual and also with the constitution of the day, etc. However, it has been proven that the subliminal period is always short enough when it reaches 0 , Does not exceed 06 s. Optionally, it is also provided that the viewer can adjust the Subliminalzeitdauer to optimally adapt to his own sensitivity.

Das Trigger-Intervall wiederum definiert, in welchen Zeitabständen die Veränderung des Anzeigeparameters durchgeführt wird. In Versuchen hat sich ein Trigger-Intervall zwischen 5 und 20 s als günstig für eine ausreichende Benetzung des Auges mit Tränenflüssigkeit erwiesen. Um eine individuelle Anpassung an die persönlichen Vorlieben und Bedürfnisse eines Betrachters zu ermöglichen, kann das Trigger-Intervall durch den Betrachter der Anzeigefläche, oder durch einen Zufallsgenerator o. dergl. auf einen Wert, der konstant gehalten wird oder zufällig variiert wird, eingestellt werden. In ähnlicher Weise kann das Trigger-Intervall gemäß einem Werteprofil eingestellt werden, welches Werteprofil beispielsweise ein Tagesprofil oder ein an die Umgebungshelligkeit angepasstes Profil ist. Zum (Selbst-)Schutz des Benutzers ist aber auch vorgesehen, die Variierbarkeit des Trigger-Intervalls nur innerhalb vorgegebener Grenzen zuzulassen.The trigger interval in turn defines at what intervals the change of the display parameter is performed. In experiments, a trigger interval between 5 and 20 s has proven to be favorable for a sufficient wetting of the eye with tear fluid. To allow individual adaptation to a viewer's personal preferences and needs, the trigger interval may be set by the viewer of the display area, or by a random number generator or the like, to a value that is held constant or is varied randomly. Similarly, the trigger interval can be set according to a value profile, which value profile is for example a daily profile or a profile adapted to the ambient brightness. For the (self-) protection of the user but is also provided to allow the variability of the trigger interval only within predetermined limits.

Das Anzeigesystem 1 kann beispielsweise durch einen Computer 8 mit angeschlossenem Display 2 realisiert sein. Der Computer 8 wiederum umfasst die als Recheneinheit ausgebildeten Anzeigeveränderungsmittel 5 sowie die als Grafikkarte ausgebildete Anzeigeeinrichtung 4. Zusätzlich weist der Computer 8 einen internen Speicher 7 zur Abarbeitung von Computerprogrammen auf, die von einem computerlesbaren Medium 6, wie einer Diskette, einer Festplatte oder über ein Datennetzwerk, wie das Internet, in den internen Speicher 7 geladen werden.The display system 1 can be realized, for example, by a computer 8 with a connected display 2. In addition, the computer 8 has an internal memory 7 for processing computer programs that from a computer-readable medium 6, such as a floppy disk, a hard disk or via a Data network, such as the Internet, are loaded into the internal memory 7.

Obwohl das erfindungsgemäße Verfahren zum Anzeigen visueller Information auf einer Anzeigefläche als Hardwaregerät oder -chip implementiert werden kann, eignet es sich auch vorzüglich zur Software-Implementierung mittels des Computers 8, d.h. als Computerprogrammprodukt, das auf dem computerlesbaren Medium 6 gespeichert ist und im Computer 8 abgearbeitet werden kann. Zur Implementierung des erfindungsgemäßen Verfahrens können verschiedene Ansätze gewählt werden, wie anhand der folgenden Beispiele näher erläutert wird.Although the inventive method of displaying visual information may be implemented on a display surface as a hardware device or chip, it is also particularly suitable for software implementation by means of the computer 8, i. as a computer program product which is stored on the computer-readable medium 6 and can be processed in the computer 8. Various approaches can be chosen to implement the method according to the invention, as will be explained in more detail with reference to the following examples.

In Fig. 2 ist die Anzeigefläche 3 für den Fall dargestellt, dass der Computer 8 ein Betriebssystem aufweist, das die Darstellung mehrerer übereinanderliegender Anzeigeebenen auf einer Anzeigefläche erlaubt. In der untersten Anzeigeebene 3a ist die visuelle Information 9 dargestellt. Als oberste Anzeigeebene 3b ist ein transparenter Bereich vorgesehen, der für die Subliminal-Zeitdauer gemäß dem Anzeigeparameter P in einen nicht vollständig transparenten Modus umgeschaltet wird. Der Betrachter der Anzeigefläche 3 merkt nichts von dieser subliminalen Änderung der Darstellung. Es sei erwähnt, dass die oberste Anzeigeebene 3b sich nicht über die gesamte Anzeigefläche 3 erstrecken muss, sondern es als für das Funktionieren der Erfindung ausreichend erkannt wurde, wenn sie nur einen Teil der Anzeigefläche 3 einnimmt. Vorteilhaft kann als Teilbereich ein Bereich 3c gewählt werden, der die Aufmerksamkeit des Betrachters an sich zieht, weil sich in diesem Bereich 3c ein Mauszeiger 10 oder ein anderer die Aufmerksamkeit des Betrachters hervorrufender Indikator, wie z.B. ein Cursor, ein Eingabefeld oder ein sonstiges aktives Bildschirmelement befindet. Gemäß einer alternativen Ausführungsform kann auch durch nicht dargestellte Aufmerksamkeitsdetektionsmittel, wie z.B. Iriserkennung, detektiert werden, auf welchen Bereich der Anzeigefläche sich die Aufmerksamkeit des Betrachters momentan richtet und der Bereich, in dem ein Anzeigeparameter für die Subliminal-Zeitdauer verändert wird, entsprechend ausgewählt werden. Es versteht sich weiters, dass die Position und/oder Größe der Anzeigeebenen 3b bzw. des Anzeigebereiches 3c verändert werden kann.In Fig. 2 For example, the display area 3 is illustrated in the case that the computer 8 has an operating system that allows the display of multiple superimposed display levels on a display area. In the lowest display level 3a, the visual information 9 is shown. As the uppermost display level 3b, a transparent area is provided, which is switched over to the subliminal time duration according to the display parameter P in a not completely transparent mode. The viewer of the display area 3 does not notice anything of this subliminal change of presentation. It should be noted that the uppermost display plane 3b does not have to extend over the entire display area 3, but has been sufficiently recognized as functioning for the invention if it occupies only a part of the display area 3. Advantageously, a region 3c can be selected as the subregion, which attracts the viewer's attention, because in this region 3c a mouse pointer 10 or another indicator causing the viewer's attention, such as eg a cursor, an input field or another active screen element located. According to an alternative embodiment, it can also be detected by attention detection means not shown, such as iris recognition, on which area of the display area the viewer's attention is currently directed and the area in which a display parameter for the subliminal period is changed, be selected accordingly. It is further understood that the position and / or size of the display levels 3b and the display area 3c can be changed.

Wenn der Computer 8 zur Darstellung von Anzeigefenstem in der Anzeigefläche 3 ausgebildet ist, wie in Fig. 3 schematisch dargestellt, wo ein Anzeigefenster 11a die visuelle Information 9 enthält, kann ein transparentes Fenster 11b über zumindest einen Bereich der visuellen Information 9 gelegt und dieses transparente Fenster 11b für die Subliminal-Zeitdauer gemäß dem Anzeigeparameter in einen nicht vollständig transparenten Modus umgeschaltet werden. Anstelle des zwischen einem transparenten und einem nicht vollständig transparenten Mode umschaltbaren Fensters 11b kann auch ein Fenster 11c, das nicht vollständig transparent ist, für die Subliminal-Zeitdauer eingeblendet und wieder ausgeblendet werden. In einer alternativen, nicht dargestellten Ausführungsform kann die Darstellung des momentan aktiven Anzeigefenster gemäß einem Anzeigeparameter für eine Subliminal-Zeitdauer verändert werden, wobei auf dieses aktive Fenster Benutzereingaben wirken und somit von einer erhöhten Aufmerksamkeit des Benutzers für dieses aktive Fenster ausgegangen werden kann.When the computer 8 for displaying display windows is formed in the display surface 3, as in FIG Fig. 3 2, where a display window 11a includes the visual information 9, a transparent window 11b may be overlaid on at least a portion of the visual information 9 and this transparent sub-period window 11b may be switched to a non-transparent mode according to the display parameter. Instead of the window 11b switchable between a transparent and a not completely transparent mode, a window 11c, which is not completely transparent, can also be superimposed and hidden again for the subliminal period. In an alternative embodiment, not shown, the display of the currently active display window may be changed in accordance with a subliminal display parameter, and user inputs may be applied to that active window, thus assuming increased user attention to that active window.

Wesentliches Merkmal der Erfindung ist es, dass die Darstellung der visuellen Information auf der Anzeigefläche für einen subliminal kurzen Zeitraum so stark gegenüber der sonstigen Darstellung verändert wird, dass der Betrachter unbewusst durch diese kurzzeitige Kontrastierung zu einem Blinzeln veranlasst wird. Wie erwähnt, wird zum Erzielen dieser kontrastierenden Darstellung für die Subliminal-Zeitdauer ein Anzeigeparameter verändert, der Anzeigehelligkeit, -farbe, -beleuchtung, -kontrast, -fokus, -frequenz oder dergleichen umfasst. Ebenso ist es zur Erzielung des kontrastierenden Effektes möglich, die Anzeigefläche vollständig ab- und wieder einzuschalten, vorausgesetzt, das Display ist in der Lage, schnell genug zu reagieren, so dass das Aus- und Einschalten im subliminalen Bereich bleibt und vom Betrachter daher nicht als Bildschirmflackern empfunden wird.An essential feature of the invention is that the representation of the visual information on the display surface is changed so strongly in relation to the other representation for a subliminally short period of time that the viewer is unconsciously caused to blink by this brief contrasting. As noted, to achieve this contrasting presentation for the subliminal period, a display parameter is changed that includes display brightness, color, lighting, contrast, focus, frequency, or the like. Similarly, to achieve the contrasting effect, it is possible to completely turn the display surface off and on again, provided that the display is capable of reacting fast enough so that switching off and on remains in the subliminal range and is therefore not considered by the viewer Screen flicker is felt.

In technischer Hinsicht kann die kontrastierende Darstellung auf der Anzeigefläche eines Display durch Bildauf und -abbau, Pixelauf- und -abbau, Bild/Pixeleinblendung und -ausblendung, Bild/Pixelüberlagerung oder Bild/Pixelveränderung hervorgerufen werden. Um die beschriebenen Veränderungen herbeizuführen kann in programmiertechnischer Hinsicht der Alphawert einer Bitmap auf einen nicht transparenten Wert gesetzt werden. Die Anzahl der manipulierten Pixel kann variiert werden, es kann ein Repeat-Timer programmiert werden, der das Trigger-Intervall definiert.Technically, the contrasting representation on the display surface of a display may be caused by image build-up, pixel build-up, image / pixel fade-in and fade-out, image / pixel overlay, or image / pixel change. To bring about the changes described, the alpha value of a bitmap can be set to a non-transparent value in terms of programming technology. The number of manipulated pixels can be varied, a repeat timer can be programmed which defines the trigger interval.

Damit sich der Benutzer auch sicher ist, dass das als Computer-implementierte erfindungsgemäße Verfahren tatsächlich vom Computer abgearbeitet wird, kann beispielsweise ein Icon in einer Taskleiste der Anzeigefläche eingeblendet werden. Es kann aber auch vorgesehen werden, dass der Benutzer den Computer in einen Modus schalten kann, indem die Veränderung des Anzeigeparameters gelegentlich oder durch Benutzereinwirkung für eine supraliminale Zeitdauer durchgeführt wird, damit der Benutzer die Anzeigenveränderung bewusst erkennen kann.So that the user is also sure that the method implemented as a computer-implemented inventive method is actually processed by the computer, for example, an icon in a taskbar of the display area can be displayed. It can however, it is also contemplated that the user may switch the computer to a mode by performing the alteration of the display parameter occasionally or by user action for a supraliminale period of time, so that the user can consciously recognize the display change.

Die Anzeigefläche muss nicht die Bildfläche eines Display sein, sondern es kann sich gemäß der Erfindung auch um eine Projektionsfläche oder eine mit der visuellen Information versehene Trägerfläche, wie z.B. eine Druckschrift, handeln. Als Anzeigefläche ist aber beispielsweise auch eine von einer Bedienperson visuell zu inspizierende Oberfläche eines Gegenstandes, insbesondere Industrieproduktes, zu verstehen. Fig. 4 zeigt ein Ausführungsbeispiel, bei dem visuelle Information 15 von einem Projektor 14 bzw. einem computergesteuerten Videobeamer auf eine Projektionsfläche 13 projiziert wird. Betrachter der Projektionsfläche 13 unterliegen ebenso der Augenermüdung und dem immer gleichen Fokussieren auf die Projektionsfläche und neigen daher bei zu angestrengtem Schauen dazu, das Blinzeln zu unterlassen. Um erfindungsgemäß dennoch bei diesen Betrachtern Augenblinzeln zu veranlassen, ist ein zweiter Projektor 16 vorgesehen, der in Trigger-Intervallen für eine subliminal kurze Zeitdauer Licht 17 auf die Projektionsfläche 13 strahlt. Es ist dafür Sorge zu tragen, dass im Projektor 16 Leuchtmittel verwendet werden, die in subliminaler Zeit ein- und wieder ausgeschaltet werden können, oder durch eine Blende o. dergl. abgedeckt werden können. Der Projektor 16 kann durch eine Lampe ersetzt werden. Ebenso können die beiden Projektoren 14, 16 bzw. der Projektor 14 und eine geeignete Lampe ineinander integriert sein, so dass nur ein Linsensystem verwendet werden muss.The display surface need not be the image surface of a display, but according to the invention it may also be a projection surface or a support surface provided with the visual information, such as a printed publication. As a display surface but is for example a to be visually inspected by an operator surface of an object, in particular industrial product to understand. Fig. 4 shows an embodiment in which visual information 15 is projected from a projector 14 and a computer-controlled video beamer on a projection surface 13. Viewers of the projection surface 13 are also subject to eye fatigue and always the same focus on the projection surface and therefore tend when too strained looking to refrain from blinking. However, in order to induce blinking in these observers according to the invention, a second projector 16 is provided, which emits light 17 on the projection surface 13 at trigger intervals for a subliminally short period of time. Care must be taken to ensure that 16 bulbs are used in the projector, which can be switched on and off again in subliminal time, or can be covered by a shutter or the like. The projector 16 can be replaced by a lamp. Likewise, the two projectors 14, 16 or the projector 14 and a suitable lamp can be integrated with each other, so that only one lens system must be used.

Fig. 5 zeigt schematisch ein weiteres Beispiel, wie das erfindungsgemäße Verfahren implementiert werden kann. Bei diesem Beispiel besteht die Anzeigefläche einerseits in einer mit visueller Information versehener Trägerfläche, nämlich den aufgeschlagenen Seiten eines Buches 20, und andererseits in der Oberfläche eines zu inspizierenden Gegenstandes 21. Bei diesen Beispielen kann die Anzeigefläche selbst natürlich nicht direkt verändert werden, sondern sie ergibt sich durch Bestrahlung mit Licht 22 aus einer Lichtquelle 18. Jedoch besteht das Problem der Überanstrengung der Augen und damit verbundenem Unterlassen des Blinzelns auch bei angestrengtem Lesen oder angestrengter Betrachtung des zu inspizierenden Gegenstandes 21. Zur Durchführung des erfindungsgemäßen Verfahrens ist eine zweite Lichtquelle 19 vorgesehen, die so ausgebildet ist, dass sie in Trigger-Intervallen für einen subliminalen Zeitraum ein- und wieder ausgeschaltet werden kann, oder durch eine Blende o. dergl. für einen subliminalen Zeitraum abgedeckt werden kann. Das Licht 23 der Lichtquelle 19 bestrahlt sowohl den Gegenstand 21 als auch das Buch 20 und überlagert - allerdings nur für den subliminalen Zeitraum - das Licht 22 aus der allgemeinen Lichtquelle 18, so dass man aufgrund dieser Lichtüberlagerung davon sprechen kann, dass ein Anzeigeparameter der Anzeigefläche durch das Bestrahlen der Anzeigefläche mit Licht aus der Lichtquelle 19 verändert wird. Diese Ausführungsform der Erfindung eignet sich vorzüglich zum Einsatz in Bibliotheken oder Industrie-Produktionshallen. Fig. 5 schematically shows a further example of how the method according to the invention can be implemented. In this example, the display surface consists, on the one hand, of a visually provided support surface, namely the open pages of a book 20, and, on the other hand, in the surface of an object 21 to be inspected. In these examples, the display surface itself, of course, can not be directly changed, but results However, there is the problem of straining the eyes and the related omission of blinking, even with strained reading or strenuous viewing of the object 21 to be inspected. A second light source 19 is provided for carrying out the method according to the invention. which is designed so that it can be switched on and off at trigger intervals for a subliminal period, or covered by a shutter or the like for a subliminal period. The light 23 of the light source 19 irradiates both the object 21 and the book 20 and superimposes the light 22 on the general, albeit only for the subliminal period Light source 18, so that it can be said that a display parameter of the display surface by irradiating the display surface with light from the light source 19 is changed due to this light overlay. This embodiment of the invention is excellently suited for use in libraries or industrial production halls.
