First Claim
1. A data entry arrangement for enabling entry of data into a portable electronic device by a user using one unsupported hand, the data entry arrangement comprising:
- data input means for generating a data entry signal in response to user manipulation thereof, said signal corresponding to a value of a measurement parameter, variable in dependence upon said user manipulation; and
a processing means for interpreting said signal, wherein each of a plurality of ranges of possible parameter values is associated with one of a plurality of groups of possible data entries.

Abstract
A device seeks to convert the natural motions of a human hand and fingers into characters on a compact portable electronic device. The handset arrangement allows data to be entered conveniently into a small telephone with the hand that is holding the handset and without necessitating the support of a surface or a second hand. Fine-grained position or pressure measurement devices are incorporated into at least one button, the presence of a user'"'"'s finger and the degree of pressure applied by the user are mapped to particular data entry choices. The device thus provides a convenient alternative to a conventional keypad.

24. A data entry arrangement for enabling entry of data into a hand-portable electronic device by a user using one unsupported hand, the data entry arrangement comprising:
-
data input device, adapted to generate a data entry signal in response to user manipulation thereof, said signal corresponding to a value of a user-influenced measurement parameter, wherein each of a plurality of ranges of possible values of the parameter are associated with a respective one of a plurality of groups of possible data entries;
a first auxiliary data entry component, which in operation outputs a confirmation signal for confirming the selection of the respective group of possible data entries and for confirming a selection of a certain data entry from amongst said respective group;
a second auxiliary data entry component, which in operation outputs a cancellation signal for cancelling selections made using the measurement component;
a processor, adapted to process said data entry signal, said confirmation signal and said cancellation signal, and adapted to generate a control signal; and
a display, adapted to display selected and confirmed data entries in accordance with the control signal.
