Patent ID: 7266780

Claim:
A method for the entering alphanumeric or non-Western character based data into an electronic device, comprising: a user entering data into an electronic device using a deterministic input element and a non-deterministic input element wherein the deterministic input element and a non-deterministic input element are coupled to the electronic device; a feedback element coupled to the electronic device displaying a sequence of data choices to the user; the user navigating a tree of possible data completions in order to select a particular data completion to be entered into the electronic device, further comprising: selecting a branch of the tree of possible data completions by selecting from one or more data entry choices via the deterministic input element; increasing a rate of motion or extent of deflection of the non-deterministic input element causing a reduction in a precision of the data completions displayed to the user wherein the reduction in the precision corresponds to reducing a viewable depth of the tree; and decreasing the rate of motion or extent of deflection of the non-deterministic input element causing an increase in the precision of the data completions displayed to the user wherein the increase in the precision corresponds to increasing a viewable depth of the tree. the user stopping the motion or releasing the deflection of the non-deterministic input element in order to display a full precision of the data completions displayed to the user.
