Solution Overview

Problem

Existing electronic devices that use infrared sensors for gesture detection and processing lack convenience in enlarging or reducing screens and changing line thickness without requiring users to release their stylus or transition to a menu screen, limiting user interaction.

Innovation Solution

An electronic device equipped with a communication interface for a movement detection apparatus including a barometric pressure sensor, allowing the controller to adjust screen size and line thickness based on changes in barometric pressure detected by the sensor, enabling users to perform these actions from a more distant location without releasing the stylus.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users want to enlarge or reduce the screen or change line thickness, then they need to release the stylus or transition to a menu screen, but this reduces operational efficiency and user convenience

Engineering Contradiction:

Improveconvenience of screen adjustmentVSAvoidoperational efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The system automatically detects barometric pressure changes to determine stylus position and automatically adjusts screen enlargement/reduction or line thickness based on this detection, eliminating the need for users to manually release the stylus or navigate to menu screens

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system changes display parameters (screen size, line thickness) based on detected barometric pressure values that correspond to different stylus positions, allowing dynamic adjustment without manual intervention

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If users want to adjust screen size or line thickness from a distance, then they need to be close to the device to access menu options, but this limits the operational range

Engineering Contradiction:

Improveoperational rangeVSAvoidsensor integration complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The barometric pressure sensor acts as an intermediary that indirectly detects stylus position by measuring atmospheric pressure changes caused by the stylus's proximity, enabling distance-based control without direct contact or close proximity requirements

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system replaces direct mechanical interaction (releasing stylus, touching screen) with atmospheric pressure-based detection, allowing control through subtle pressure changes rather than physical contact

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

An electronic device includes a communication interface, a display, and a controller that controls screen display of the display. The communication interface communicates with a movement detection apparatus provided with a barometric pressure sensor. The controller enlarges or reduces a screen of the display in accordance with a change in the barometric pressure detected by the barometric pressure sensor. The controller may enlarge the screen if the change is a rise in barometric pressure and reduce the screen if the change is a drop in barometric pressure.
