Embodiment Construction

[0015] figure 1 An operating device MMI is shown, which contains a display device, such as a graphics display DPL, and a keyboard device TAS with various keys tas. Here, the key tas is occupied multiple times to input multiple characters. Thus, the key on which the character "2" is written is occupied by the characters "2", "A", "B" and "C", for example. Therefore, the key can be used to input both the number zif and the letter bs. An embodiment of the invention provides that at least one button is additionally occupied by the symbol sym, which is indicated in the figure by the button with the character "3".

[0016] In order to control the operating device MMI, a processing device PE, for example a microcontroller, is provided, which consists of a processor CPU, a memory device SPE and an input / output interface via which access to the operating device MMI can be achieved. Connection. The elements of the processing device are interconnected via a bus system BUS.

Abstract

The present invention relates to methods and apparatus for entering alphanumeric characters. For the input of alphanumeric characters by means of keys that are occupied multiple times, the assignment of the available characters to the number of key presses required to enter the character is automatically adapted to the behavior of the user when entering a sequence of characters . According to the present invention, as a response to inputting a first number, it is only necessary to operate the keys occupied by the second number once for inputting a second number; and when inputting a sequence of characters, as a response to inputting a first letter, for Entering the second letter requires only a single actuation of the key assigned to the second letter. As a result, alphanumeric characters can be input intuitively and simply by means of multiple-occupied keys.

Description

technical field [0001] The invention relates to a method and a device for inputting alphanumeric characters, wherein the keys for inputting are assigned multiple times, ie are provided with a plurality of characters. Background technique [0002] With the rapid popularity of mobile telephony, mobile data transmission, especially in the form of so-called short messages, which are transmitted via the so-called short message service (SMS), is being developed almost rapidly in recent times. In this case, the input of text information into the mobile radio telephone is generally carried out via a keyboard arrangement comprising 12 keys, wherein the individual keys for entering letters, numbers and special characters are assigned multiple times. Depending on the character to be input, the keys assigned to the character should be pressed according to the number of key operations required for input of the character that are permanently assigned to the character. Thus, to enter the ...
