Solution Overview

Problem

Users face difficulties in accurately selecting function elements on computing devices, especially in unstable environments or with limited dexterity, due to the need for precise finger movements or screen enlargement, which can be challenging on small screens or during multitasking.

Innovation Solution

A computing device that displays user-selectable function elements in a first format, allowing users to select a portion of the screen, and then displays associated function elements in a second format, highlighting and enlarging them for easier selection, using a user-assist mode that identifies nearby elements and provides visual cues for accurate choice.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the screen is enlarged by wiping fingers over the screen, then the area of interest is expanded to facilitate accurate selection, but the user must concentrate for an extended period and exhibit substantial manual dexterity

Engineering Contradiction:
Improveselection accuracyVSAvoidoperational complexity
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The system performs preliminary action by automatically detecting and enlarging the area of interest before the user needs to make a selection. The device proactively identifies regions containing function elements and presents them in an enlarged format, eliminating the need for users to perform the complex finger-wiping gesture and extended concentration required by manual zooming methods.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system serves itself by automatically identifying areas of interest and presenting enlarged views without requiring user intervention. The device monitors screen content, detects function elements, and autonomously provides enlarged presentations of relevant areas, freeing the user from the burden of manual dexterity requirements while maintaining high selection accuracy.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If the screen is enlarged by wiping fingers over the screen, then the area of interest is expanded, but the user must shrink the screen back to its former size to continue viewing

Engineering Contradiction:
Improveselection accuracyVSAvoidtime for screen manipulation
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system prepares the enlarged view in advance and maintains it until the selection is complete, eliminating the need for users to perform the time-consuming reverse wiping action to restore the original screen size. The enlarged presentation persists throughout the selection process, allowing users to immediately return to normal viewing without additional manual operations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system introduces an intermediary mechanism that automatically manages the transition between normal and enlarged views. Instead of requiring users to manually shrink the screen, the device acts as a mediator that detects when selection is complete and automatically restores the original display, saving time and reducing operational complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If a user performs navigational operations or multi-tasks simultaneously, then productivity increases, but the ability to accurately select function elements is compromised

Engineering Contradiction:
Improvemulti-tasking capabilityVSAvoidselection accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The system provides self-service by automatically identifying and presenting enlarged areas of interest without requiring user attention or manual manipulation. This allows users to engage in multi-tasking or navigational operations while the device autonomously manages the display enhancement, maintaining selection accuracy even when the user's attention is divided.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary detection and presentation of areas of interest before the user needs to make selections, allowing users to focus on other tasks. The automatic identification and enlargement of relevant screen areas occurs in the background, ensuring accuracy is maintained regardless of the user's cognitive load or concurrent activities.

Inventive Principle:
Principle #10Preliminary action

4Area of stationary object

If the screen size is small, then the device is portable and compact, but users experience difficulty selecting function elements accurately

Engineering Contradiction:
Improvescreen sizeVSAvoidselection accuracy
Core Design Contradiction:
Area of stationary objectVSMeasurement precision

Solution Approach 1:

The system resolves the contradiction by transitioning from a two-dimensional flat screen to a multi-dimensional presentation. When area of interest is detected, the system creates an enlarged overlay or popup that adds depth and scale to the display, allowing small-screen devices to provide large-element interactions without sacrificing portability or requiring physical screen enlargement.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
