Solution Overview

Problem

Existing portable electronic devices with dual display screens face usability issues due to the mismatch between user operations and data movement, as users must depress a tab to transfer data between screens, leading to a sense of incongruity and low usability.

Innovation Solution

Implementing a system where data on one display screen is moved to another upon a slide operation on a touch panel, aligning user manipulation with data movement, and allowing data transfer based on predetermined orientations and opening states of the screens.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a depression operation on a tab is used to transfer data between display screens, then data transfer functionality is achieved, but usability deteriorates due to incongruity between user motion and data movement

Engineering Contradiction:
ImproveusabilityVSAvoidoperation complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent inverts the conventional depression operation by implementing a slide operation instead. When the user slides their finger or stylus across the touch panel, the display data moves in the same direction as the sliding motion, creating intuitive congruity between user action and data movement. This inversion of the operation type resolves the usability issue caused by the mismatch between depression motion and data transfer direction.

Inventive Principle:
Principle #13The other way round (Inversion)

2Adaptability or versatility

If data is moved between display screens in all orientations, then data transfer flexibility is improved, but unnecessary data movement occurs reducing usability

Engineering Contradiction:
Improvedata transfer flexibilityVSAvoidusability
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent applies local quality by making the data transfer function orientation-dependent. Instead of enabling data movement in all orientations uniformly, the system selectively enables data transfer only when the device is in a predetermined orientation (such as when display screens are positioned side-by-side). This localized activation of the transfer function prevents unnecessary data movement in inappropriate orientations while maintaining flexibility when needed.

Inventive Principle:
Principle #3Local quality

AI summary

An information processing device includes a plurality of display screens, a display control means that controls a display operation with respect to each of the display screens, a touch panel attached to the surface of at least one display screen, and an operation reception means that receives a depression input externally applied to the touch panel by a predetermined pressing means. When the operation reception means receives a slide operation sliding the pressing means on the touch panel, the display control means moves and displays display data of one display screen on another display screen.
