Solution Overview

Problem

Current user interfaces for portable electronic devices, such as smartphones, face challenges in providing a user-friendly experience due to limitations in single touch input, multi-touch input, gesture recognition, and gaze-based control, particularly when handling large screens or specific edge inputs.

Innovation Solution

The method and electronic device employ a touch screen that detects inputs within a predetermined distance from the edge, displays cursors and menus accordingly, and utilizes gaze direction to determine functions, allowing for intuitive control through single and multi-touch inputs, as well as gesture recognition, to enhance user interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a touch input is detected near the edge of the touch screen, then cursor control precision is improved, but the cursor position may become too close to the screen edge causing operational difficulty

Engineering Contradiction:
Improvecursor control precisionVSAvoidcursor positioning ease
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

An offset value is introduced as an intermediary parameter between the touch input position and the cursor position. The processor calculates the cursor position by adding this offset value to the touch input coordinates, ensuring the cursor is positioned at a comfortable distance from the screen edge while maintaining precise control responsiveness.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the cursor offset distance is increased to improve operability, then ease of operation is improved, but cursor control precision deteriorates

Engineering Contradiction:
Improvecursor positioning easeVSAvoidcursor control precision
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The offset value is made dynamic rather than fixed. The processor adjusts the offset value based on the specific touch input position and screen characteristics, optimizing the balance between operability and precision for each interaction scenario. This dynamic adjustment allows the system to adapt to different user needs and screen regions.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If gaze direction detection is added to determine functions, then user interface versatility is improved, but device complexity increases

Engineering Contradiction:
Improveuser interface versatilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The touch screen system is enhanced with multi-functionality by integrating gaze direction detection capabilities. The same touch screen processor handles both traditional touch inputs and gaze-based function determination, allowing a single component to serve multiple interaction modes without requiring entirely separate systems.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

An electronic device that uses a method of providing user interface is provided. The method includes detecting a first touch input within a predetermined distance from an edge of a touch screen, displaying a first cursor at a position spaced away from the first touch input in response to the first touch input, detecting a movement of the first touch input in a first area, the first area being mapped to a screen of the touch screen and determined according to a position where the first touch input occurs, and moving the first cursor in the same manner as the movement of the first touch input in the first area.
