Solution Overview

Problem

Current devices lack adequate solutions for accurately correcting typographical errors in text input, as the appropriate correction varies based on factors such as the number and style of body parts used for input, which existing technologies fail to account for effectively.

Innovation Solution

A device with a processor and touch-enabled display that determines the number and style of body parts used for input, executing text corrections based on this determination, including a method to differentiate between one or two body parts and specific typing styles to perform appropriate text alterations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If automatic text correction is performed without considering body part input style, then correction speed is improved, but correction accuracy deteriorates

Engineering Contradiction:
Improvecorrection speedVSAvoidcorrection accuracy
Core Design Contradiction:
Loss of timeVSMeasurement precision

Solution Approach 1:

The system dynamically adjusts correction behavior based on detected typing patterns. It monitors body part usage in real-time and adapts correction sensitivity accordingly, transitioning between different correction modes (aggressive vs. conservative) based on the detected input style

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes correction parameters based on body part detection results. When single-body-part typing is detected, it applies different correction thresholds and confidence levels compared to multi-body-part typing, optimizing accuracy for each typing style

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If text correction considers multiple body parts usage, then correction accuracy is improved, but system complexity increases

Engineering Contradiction:
Improvecorrection accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system segments the typing detection process into distinct components: body part detection module, typing pattern analysis module, and correction decision module. This modular approach manages complexity by separating concerns while maintaining accurate multi-factor analysis

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system introduces an intermediary typing pattern analysis layer between raw input detection and correction execution. This intermediary processes body part information and translates it into correction parameters, simplifying the overall system architecture

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

In one aspect, a device includes a processor, a touch-enabled display accessible to the processor, and storage accessible to the processor. The storage bears instructions executable by the processor to determine a number of body parts with which a user provides input to the device and to perform a text alteration based at least in part on the determination of the number of body parts.
