Device and method for quickly selecting text from a list using a numeric telephone keypad
First Claim
1. A numerical telephone keyboard, comprising a keyboard of a digital telephone wherein at least one key thereof is movable in response to an applied force and has associated therewith a plurality of different text items, the keyboard being equipped with at least one pressure sensor for measuring a relative strength of an applied force on the at least one key, a processing unit means for evaluating input from the keyboard as to which of the at least one key has been pressed and from the at least one pressure sensor as to the relative strength of the applied force on said at least one key which has been pressed, and a display means for displaying discrete text information determined by the processing unit means in response to the input.

Abstract
The aim of the invention is to provide a device and a method for selecting text from an electronic memory using a numeric telephone keyboard. To this end, a digital telephone keyboard has at least one pressure sensor sensing the pressure exerted on one or more keys, control electronics processing an input via key confirmation and text display. The pressure exerted on the keys of the digital telephone keyboard is detected and measured for every key by a pressure sensor. The respective pressure value is transmitted to and processed by control electronics. The measured pressure value is shown on a display for every key. The pressure value exerted is changed for the key pressed, if necessary, and once the correct pressure value is reached and shown on the display, the pressure value for every pressed key and information on the selected key are transmitted for further processing of the measured values.

5. A method for selection and recall of information stored in lists using a keyboard of a digital telephone having a plurality of keys, at least one of said keys being movable in response to an applied force and being associated with at least two distinct text characters, comprising the steps of:
-
applying a variable, controlled force to a first of the at least one of said keys of the keyboard, measuring a value of relative strength of an applied force with a pressure sensor, transmitting the measured value of relative strength to a processing unit, evaluating the measured value by way of the processing unit and associating the measured value with an item of discrete text information, displaying the discrete text information on a display of the digital telephone, optionally changing the applied force applied to said one of said keys, transmitting information about the changed applied force to the processing unit for further processing. - View Dependent Claims (6, 7)
