Solution Overview

Problem

Existing display technologies require users to manually determine the number of fingers used for scrolling actions across multiple display areas, making actions for updating display states non-intuitive and complex.

Innovation Solution

A display device and control method that uses a posture sensor and touch panel to detect directional movements, allowing users to perform intuitive actions by differentiating between single and multiple finger touches to move or scroll display information within or between display areas.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If different action instructions (one finger vs two fingers) are used to scroll in different display areas, then scrolling control is achieved, but user operation becomes non-intuitive and complicated

Engineering Contradiction:
Improveintuitiveness of scrolling actionVSAvoidcomplexity of action instruction
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies local quality by making each display area have distinct scrolling characteristics. The first display area responds to one-finger scrolling while the second display area responds to two-finger scrolling, creating localized interaction patterns that are intuitive for each specific area rather than requiring users to remember global rules.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent segments the scrolling control mechanism by separating the action instructions for different display areas. Instead of using a unified scrolling method across all areas, it divides the scrolling behavior into area-specific segments with different finger requirements, making each area's scrolling independent and intuitive.

Inventive Principle:
Principle #1Segmentation

2Productivity

If users must determine the number of fingers to use for scrolling, then scrolling action can be received, but user burden increases and operation becomes complicated

Engineering Contradiction:
Improveefficiency of display state updateVSAvoiduser burden for determining action
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The system performs self-service by automatically determining which display area the user intends to scroll based on the touch input location. Instead of requiring the user to pre-determine the target area and select the appropriate finger count, the system detects the touch position and autonomously identifies the correct display area and scrolling behavior.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent implements preliminary action by pre-configuring each display area with its specific scrolling response (one-finger for first area, two-fingers for second area). This preliminary setup eliminates the need for users to make real-time decisions about finger count, as the appropriate action is already determined by the display area's predefined characteristics.

Inventive Principle:
Principle #10Preliminary action

AI summary

A display device (9) according to the present invention includes a display unit (91) capable of displaying display information in each of a plurality of display areas, an operation unit (92) that detects a position of an action performed on a display surface, the display information being displayed on the display surface in the display unit (91), and a control unit (93) that performs control so that, when a movement of the action position detected by the operation unit (92) from the position on the display information is detected, the display information is displayed in another display area located in a direction of the movement of the action position.
