Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users often inadvertently type on incorrect keypads displayed on touch-sensitive devices, leading to gibberish entries that require manual correction, as they may not recognize the incorrect interface for their intended input.

Innovation Solution

A method and apparatus that sense user input on a touch-sensitive device, determine if it corresponds to a different keypad, and provide corresponding inputs based on a dictionary associated with the intended keypad, allowing for automatic correction and display of correct inputs on the device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual correction is required when users type on incorrect keypads, then input accuracy can be improved, but user time and operational efficiency deteriorate

Engineering Contradiction:

Improveinput accuracyVSAvoiduser time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system automatically detects when a user has typed on the wrong keypad and self-corrects the input by interpreting the physical key positions against the intended virtual keypad layout, eliminating the need for manual deletion and re-entry of gibberish text

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system provides feedback to users by displaying suggested correct inputs based on their physical typing pattern, allowing users to confirm or reject corrections, thus improving input accuracy while minimizing time loss

Inventive Principle:

Principle #23Feedback

2Measurement precision

If users must manually delete and retype inputs on incorrect keypads, then input accuracy can be ensured, but ease of operation deteriorates

Engineering Contradiction:

Improveinput accuracyVSAvoidease of operation

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The system automatically detects wrong keypad usage and provides correction suggestions without requiring users to manually delete and retype, making the correction process effortless while maintaining input accuracy

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system pre-calculates and displays suggested correct inputs based on the user's physical typing pattern before the user needs to correct anything, reducing the operational steps required

Inventive Principle:

Principle #10Preliminary action

3Loss of time

If automatic correction is implemented, then user time is saved, but device complexity increases

Engineering Contradiction:

Improveuser timeVSAvoiddevice complexity

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The system uses the existing touch-sensitive display for multiple functions: displaying the virtual keypad, capturing user input, and showing correction suggestions, thereby implementing automatic correction without adding separate hardware components

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Ease of operation

If automatic correction is implemented, then ease of operation is improved, but device complexity increases

Engineering Contradiction:

Improveease of operationVSAvoiddevice complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Method(s) and apparatus(es) relating generally to an electronic device having a display and a touch-sensitive input device are disclosed. In such a method, a first keypad is displayed on the display. Obtained is sensed information from the touch-sensitive input device responsive to user input in association with the first keypad. The user input is determined to be for a second keypad different from the first keypad. A corresponding input to the user input is determined using the sensed information in association with the second keypad. The corresponding input is displayed on the display.
