Expression by sign language can be inputted more easily and reliably, and search can be performed therefor as well. A general-purpose keyboard is divided into finger input areas in which shapes of fingers are allotted to respective key tops and upper body input areas in which divided portions of an upper body of a sign language talker are allotted to key tops so that information, which is meant by the sign language, can be inputted by the aid of the keyboard in cooperation of key inputs of the respective areas.

In einer Tastatur sind einzelnen Tasten neben Ziffern auch Buchstabengruppen zugeordnet. Zur Auswahl eines Buchstabens aus einer Gruppe sind zwei Tastenbetätigungen erforderlich; die Betätigung der Taste, die den betreffenden Buchstaben enthält, sowie eine Taste, die die Stellung des Buchstabens in einer Buchstabengruppe bezeichnet. Vorteil: Keine gesonderte Taste (Umschalttaste) für die Auswahl des gewünschten Zeichens und keine Endekennungstaste erforderlich; keine Betätigung von Tasten innerhalb einer vorgegebenen Zeit erforderlich.

Le clavier électronique actionnable d'une seule main, notamment pour gébérer des caractères alphanumériques et analogues et/ou des instructions de traitement, comprend plusieurs touches (2, 4) et un circuit électronique relié électriquement à ces touches pour interpréter l'état des touches (2, 4) et délivrer un signal indicatif de celui-ci, ce circuit électronique étant également relié à des moyens de visualisation (6) ainsi qu'à des moyens de raccordement extérieur. Il comprend au moins deux touches (2) affectées aux doigts d'une main autres que le pouce et une touche (4) affectée au pouce, chaque touche (2) affectée à un doigt de la main autre que le pouce pouvant prendre trois états distincts sous l'action dudit doigt et la touche (4) affectée au pouce peut prendre cinq états distincts sous l'action du pouce.
摘要:
A keyboard that subdivides its keys into a plurality of fields. The concurrent actuation of two single-field keys from the same field identifies a particular character. Characters are also identified by the actuation of a single key independently of any other key. Keys may be shared by more than one field. A color coding arrangement makes the two-key combination unambiguously suggested by the keyboard itself. These features make possible a reduction of the number of keys such that a full set of alphanumeric characters may be identified with a one-handed keyboard.

A method and apparatus for enhancing the operation of computer keyboards is disclosed. The invention allows touch-typing of nontouch-type keys by detecting a triggering sequence in the touch-type keys. For example, by holding down the Space Bar while depressing and releasing a second key and before release of the Space Bar, the Space Bar is seen to act as a Control key. Furthermore, the functions of non- touch-type keys may be superimposed upon touch-type keys and accessed in a similar manner. The invention interprets make codes which are generated by the keyboard when a key Is depressed and a break code which is generated by the keyboard when a key is released. If a triggering sequence of codes is detected, then the normal function of one of the touch-type keys is altered.

This invention has reference to a ticket issuing machine including a keyboard (3) to enter into the machine information about a ticket to be issued, a printer (5) to print out ticket information on a ticket, store circuits (15,20,21) for storing information about tickets being issued and with means for altering the information stored in the store circuits to control the operation of the printer 1. The keyboard 3 comprises a plurality of keys (3a) at least some of which bear more than one identification and that there are provided selection circuits capable of identifying which of the identifications is relevant to the particular syntax operation of the ticket machine.

摘要:
Generation of a character code for a selected alphabetic character is performed by depressing a plurality of keys in a particular sequence, until all those keys are simultaneously operated. Numerical character codes are generated by depressing only one key per numerical character. The circuitry distinguishes constituent key operations of a plural key operation from a single key operation for a numerical character. The circuitry includes a microprocessor (54), an arithmetic logic unit (54), and a storage (56) having a number of registers (R1-R5) for storing the history of depressed keys, and a character code table for read-out of character codes.
