Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users of handheld electronic devices often face confusion when switching between languages, leading to incorrect language selection and inefficient data entry due to the device's disambiguation function operating on the wrong language setting.

Innovation Solution

The implementation of a visual indicator on the device's display to clearly show the currently selected language, allowing users to easily identify and change the language setting through a user-friendly interface, including a selection box and tactile/audible feedback for language selection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the device provides language switching capability, then users can write text in multiple languages, but users may confuse the currently selected language and enter data in the wrong language

Engineering Contradiction:

Improvelanguage switching capabilityVSAvoidlanguage selection accuracy

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies visual indicators (such as colored bars or highlights) next to language identifiers to clearly show the currently selected language. The visual indicator changes color or appearance to indicate the active language, making it immediately visible to users and preventing confusion about which language is currently selected for data entry.

Inventive Principle:

Principle #32Color changes

2Device complexity

If the device does not provide visual language indication, then the interface remains simpler, but users cannot easily identify the current language setting and make corrections

Engineering Contradiction:

Improveinterface simplicityVSAvoidlanguage identification ease

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The patent implements visual feedback by displaying indicators that immediately show users which language is currently selected. This feedback mechanism allows users to verify the active language before entering data and to quickly identify when a language change is needed, making the system responsive to user needs without adding significant complexity.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If users must manually correct language mismatches, then language selection flexibility is maintained, but time is lost correcting incorrect data entry

Engineering Contradiction:

Improvelanguage selection flexibilityVSAvoidcorrection time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent displays visual language indicators before users begin data entry, allowing them to verify the correct language is selected in advance. This preliminary verification prevents incorrect language selection and eliminates the need for time-consuming corrections after data has been entered.

Inventive Principle:

Principle #10Preliminary action

AI summary

A method of enabling input into a handheld electronic device comprises detecting as an ambiguous input an actuation of one or more input members, employing an operative input method language to output a number of objects that are selectable and that each comprise at least a portion of a language object that corresponds with the ambiguous input, outputting at a location adjacent the number of objects an indicator representative of an operative input method language, detecting an input from a multiple-axis input device as being a selection input with respect to the indicator and, responsive thereto, enabling a selection of an alternate input method language as the operative input method language.
