Solution Overview

Problem

Existing techniques for selecting and scrolling items on electronic devices are cumbersome and inefficient, requiring multiple key presses or keystrokes, wasting user time and device energy, particularly in battery-operated devices.

Innovation Solution

Implementing methods and interfaces that allow for faster item selection and scrolling by detecting stationary inputs with varying numbers of contacts to switch between modes of operation, enabling efficient selection and scrolling without redundant actions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If existing techniques for selecting and scrolling items are used, then item selection can be performed, but the process is cumbersome and requires multiple key presses or keystrokes

Engineering Contradiction:

Improveease of item selectionVSAvoidtime for item selection

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent combines multiple operations (scrolling and selection) into a single continuous gesture. A user performs one scrolling gesture that simultaneously navigates through items and selects the target item, eliminating the need for separate scrolling and selection actions required by existing techniques

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The system performs preliminary detection of the scrolling gesture's characteristics (duration, distance, velocity) to automatically determine selection intent. This preliminary analysis allows the system to execute selection without requiring additional user confirmation or separate selection gestures

Inventive Principle:

Principle #10Preliminary action

2Productivity

If existing techniques for selecting and scrolling items are used, then item selection can be performed, but multiple key presses or keystrokes are required

Engineering Contradiction:

Improveefficiency of item selectionVSAvoidcomplexity of user interface

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The scrolling gesture serves multiple functions simultaneously: it acts as both a navigation gesture to move through items and as a selection gesture to choose the target item. This multi-functionality eliminates the need for separate dedicated selection gestures or key presses

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system automatically analyzes the characteristics of the scrolling gesture (such as duration, distance, and velocity patterns) to self-determine when selection intent is present. This self-service capability eliminates the need for complex multi-step user commands or additional confirmation gestures

Inventive Principle:

Principle #25Self-service

3Loss of energy

If existing techniques for selecting and scrolling items are used, then item selection can be performed, but user time and device energy are wasted

Engineering Contradiction:

Improvedevice energy consumptionVSAvoidtime for item selection

Core Design Contradiction:

Loss of energyVSLoss of time

Solution Approach 1:

The selection process occurs continuously during the scrolling gesture without interruption or pause. The system monitors the gesture in real-time and executes selection as a natural continuation of the scrolling action, eliminating idle time and redundant processing steps that waste energy in existing techniques

Inventive Principle:

Principle #20Continuity of useful action
