Berührungsbildschinn mit taktiler Rüdsk^pplartg · .·*Touch screen with tactile backsc^pplartg · .·*

v Beschreibung: v Description:

^ Tastaturen zur Dateneingabe, welche ihre Funktion bzw. Beschriftung je nach Programmebene (Modus) ändern, verbessern die Mensch-Maschine-Schnittstelle. Gängige Lösungen sind der Touchscreen und die mechanische Taste mit kleiner eingebauter LCD-Anzeige.^ Keyboards for data entry, which change their function or label depending on the program level (mode), improve the human-machine interface. Common solutions are the touchscreen and the mechanical key with a small built-in LCD display.

Der Touchscreen erfüllt zwar die Anforderung nach hochauflösender Farbdarstellung, bietet aber bestenfalls eine optische bzw. akustische Eingabebestätigung. Das Fehlen der taktilen Eingabebestätigung wird vom Benutzer oft als so schwerwiegend empfunden, daß er das Tastenfeld, bestehend aus mechanischen LCD-Tasten, bevorzugt. Er nimmt dafür deren Nachteile der schlechten Auflösung, Ableseprobleme und Schwarzweiß-Darstellung in Kauf.The touchscreen does meet the requirement for high-resolution color display, but at best offers optical or acoustic input confirmation. The lack of tactile input confirmation is often perceived by the user as so serious that they prefer the keypad consisting of mechanical LCD keys. In return, they accept the disadvantages of poor resolution, readability problems and black-and-white display.

Die Neuentwicklung beruht darauf, ein weitestgehend transparentes, mechanisches Hubtastenfeld auf einem Bildschirm zu montieren (z.B. auf einem konventionellen, hochauflösenden, farbigen Röhren- bzw. LC-Bildschirm). Anwendungsgebiete sind insbesondere Bankautomaten, Ausstellungsinformation, Stadtinformantion, Fahrscheinautomaten, Lebensmittelwaagen und ähnliches.The new development is based on mounting a largely transparent, mechanical keypad on a screen (e.g. on a conventional, high-resolution, color tube or LC screen). Areas of application include in particular ATMs, exhibition information, city information, ticket machines, food scales and the like.

Die Forderung nach taktiler Rückkopplung bei hoher Darstellungsqualität ist folgendermaßen technisch umsetzbar:The requirement for tactile feedback with high display quality can be technically implemented as follows:

Ein transparentes Hubtastenfeld (1) wird auf einem herkömmlichen TouchscreenA transparent keypad (1) is placed on a conventional touch screen

(2) ohne taktile Rückkopplung montiert (Fig.l). Darunter befindet sich wie üblich der Bildschirm (3). Das Hubtastenfeld kann z.B. aus einem einzigen Spritzgußteil bestehen. Die einzelnen Tasten (4), die laschenartig von Zwischenstegen (5) abstehen, werden unter Ausnutzung der Materialflexibilität auf den darunterliegenden Touchscreen (2) gedrückt, der den Druckort lokalisiert.(2) mounted without tactile feedback (Fig.l). Below this is the usual screen (3). The lifting keypad can, for example, consist of a single injection-molded part. The individual keys (4), which protrude like tabs from intermediate bars (5), are pressed onto the touchscreen (2) underneath, which localizes the pressure point, using the flexibility of the material.

Die Ausführung der einzelnen Tasten mit Scharnieren und Rückholfedern ist eine Alternative mit verbesserter taktiler Rückkopplung, die dann einer guten Tastatur entspricht.The design of the individual keys with hinges and return springs is an alternative with improved tactile feedback, which then corresponds to a good keyboard.

BERNHARD KRSCH TÜRKISMÜHLERSTRASSE 27, 66J13 SAARBRÜCKENBERNHARD KRSCH TURKISH MÜHLER STRASSE 27, 66J13 SAARBRÜCKEN

Auf eine einzige, den gesamten Bildschirm (6) bedeckende, transparente Hubtaste (7) ist ein herkömmlicher Touchscreen (8) montiert (Fig.2). Die Taste bewegt sich bei Betätigung komplett nach unten, der Touchscreen lokalisiert den Druckort. Der Vorteil dieser Lösung ist die hohe Durchsichtigkeit des Bildschirms durch den Wegfall jeder im Blickfeld befindlichen Tastaturmechanik, es muß jedoch eine große Masse bewegt werden, was das Tastgefühl beeinträchtigt.A conventional touchscreen (8) is mounted on a single transparent lifting key (7) covering the entire screen (6) (Fig. 2). The key moves completely downwards when pressed, and the touchscreen locates the point of pressure. The advantage of this solution is the high transparency of the screen due to the elimination of any keyboard mechanism in the field of view, but a large mass has to be moved, which impairs the tactile sensation.

Dieser Entwurf beruht auf einer transparenten Scharniertaste (9) mit mechanischem Schaltkontakt (Fig.3-5). Zu bevorzugen ist eine modulare Lösung, mit der sich beliebige Tastenfelder durch Anreihen unterschiedlich großer Tasten (z.B. Zweier- oder Vierertasten), die sich z.B. in ein 30*40mm-Raster einfügen, erstellen lassen.This design is based on a transparent hinged button (9) with a mechanical switching contact (Fig.3-5). A modular solution is preferable, with which any key field can be created by arranging buttons of different sizes (e.g. two or four buttons) that fit into a 30*40mm grid, for example.

Um das zusammengesteckte Tastenfeld wird ein Anschlußrahmen gelegt, an den die Ansteuerelektronik angeschlossen wird. Diese erkennt, welcher Kontakt in der entstandenen Matrix aus X- und Y-Leitungen geschlossen wird.A connection frame is placed around the assembled keypad, to which the control electronics are connected. This recognizes which contact in the resulting matrix of X and Y lines is closed.

Die in Fig. 4 und 5 dargestellte Lösung beruht auf einer Taste, die nur aus zwei Kunststoffspritzteilen (Sockel und Kappe) und drei Blechstücken besteht. Das horizontale Blechstück (10) dient dabei gleichzeitig als Stecker (11), Leitung, Rückholfeder, Schaltzunge und Buchse (12). Das Blechstück (13) dient als Druckpunktfeder, das vertikale Blechstück (14) als Stecker (15), Leitung, Schaltkontakt und Buchse (16).The solution shown in Fig. 4 and 5 is based on a button that consists of just two plastic injection-molded parts (base and cap) and three pieces of sheet metal. The horizontal piece of sheet metal (10) serves simultaneously as a plug (11), cable, return spring, switching tongue and socket (12). The piece of sheet metal (13) serves as a pressure point spring, the vertical piece of sheet metal (14) as a plug (15), cable, switching contact and socket (16).

Die Verschmutzung des Bildschirms und die Beeinträchtigung der Tastatur durch eindringende Flüssigkeiten wird durch Rinnen (17) zwischen den Tasten ausgeschlossen.Contamination of the screen and impairment of the keyboard by penetrating liquids is prevented by grooves (17) between the keys.
