BeschreibungDescription

Tasten die auch schlecht Sehende Personen gut erkennen und ertasten können und eine daraus zusammengesetzte Tastatur zum Bedienen von Hi-Fi Geräten.Keys that even people with poor eyesight can easily recognize and feel and a keyboard made up of them for operating Hi-Fi devices.

Bisherige LösungenPrevious solutions

Die bisher am Markt verfügbaren Tasten kennzeichnen sich dadurch, daß sieThe keys currently available on the market are characterized by the fact that they

klein sind,are small,

der Kontrast zwischen Tastenfarbe und Beschriftung meißt gering ist,the contrast between key color and label is usually low ,

die Form meißt Flach oder leicht nach oben gebogen ist.the shape is usually flat or slightly curved upwards.

ProblemstellungProblem

Die bisher am Markt verfügbaren Tasten kennzeichen sich dadurch, daß sieThe keys currently available on the market are characterized by the fact that they

zu klein sind,are too small,

schlecht erkennbare Beschriftung haben,have poorly recognizable labels,

man durch die engen Abstände zwischen den Tasten und die Tastenform leicht die falsche Taste drückt,the narrow gaps between the keys and the shape of the keys make it easy to press the wrong key,

wenn die Beschriftung nicht auf der Taste, sondern darüber oder darunter ist Verwirrung, wegen der geringen Abstände zwischen den Tasten, herrschen kann, zu welcher Taste die Beschriftung gehört.If the label is not on the key but above or below it, there may be confusion as to which key the label belongs to due to the small distances between the keys.

die Tastenform nicht dem leichten Treffen dient.the shape of the keys does not make them easy to hit.

ZielsetzungObjective

Zielsetzung für die Tasten und Komponenten war es, sie so zu gestalten, daß Menschen mit schlechtem Sehvermögen sie erkennen und erfühlen können.The aim for the buttons and components was to design them so that people with poor eyesight can recognize and feel them.

LösungSolution

Größe und obere FlächeSize and upper surface

Durch die Größe soll erreicht werden, daß sie einereitsThe size is intended to ensure that it

leichter zu finden sindare easier to find

und andereseits nicht die Gefahr aufkommt, daß man,and on the other hand there is no danger that

eine andere Taste drückt,presses another key,

weil man die gewünschte Taste nicht richtig trifft. Letzteres soll noch durch die Gestaltung der oberen Fläche unterstützt werden. Dabei sollen die unterschiedlich hohen Enden ein Abrutschen vermeiden, und z.B. bei dreieckigen Tasten die Pfeilrichtung noch verdeutlichen.because you don't hit the desired key properly. The latter should be supported by the design of the upper surface. The different heights of the ends should prevent slipping and, for example, make the direction of the arrow clearer on triangular keys.

Gestaltunglayout

Die unterschiedliche Gestaltung (vgl Schutzanspruch 1 bis 5) soll dem visuellen und haptischen Erkennen dienen. Dadurch können bestimmte Funktionen bestimmten Formen zugewiesen werden. Z.B. können die Lautstärketasten dreieckig für lauter und leiser stehen.The different designs (see protection claims 1 to 5) are intended to serve visual and haptic recognition. This means that certain functions can be assigned to certain shapes. For example, the volume buttons can be triangular for louder and quieter.

Beschriftunglabeling

Als Beschriftung sind neben Ziffern und Buchstaben auch Symbole möglich.In addition to numbers and letters, symbols can also be used as labels.

Die Möglichkeit der mehrfachen Beschriftung soll z.B. dazu dienen eine Beschriftung mit Ziffern und Blindenschrift gleichzeitig vorzunehmen, oder ein Symbol mit einer Buchstabenkombination zu verbinden. Dafür muß die Beschriftung auch dezentriert aufbringbar sein.The possibility of multiple labeling is intended, for example, to enable labeling with numbers and Braille at the same time, or to combine a symbol with a combination of letters. For this, the label must also be able to be applied off-center.

Durch die haptische Erkennbarkeit der Beschriftung soll erreicht werden, daß der Benutzer nicht nur auf die visuelle Erkennbarkeit angewiesen ist. Daß ist z.B. für Blinde wichtig.The haptic recognizability of the label is intended to ensure that the user is not only dependent on visual recognition. This is important for blind people, for example.
