Input Device Protrusion Edge Detection for Continuous Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing input devices struggle to efficiently enable continuous operation inputs, particularly in directions aligned with protrusions, as users tend to stop inputs before reaching the edge, leading to suboptimal functionality in tasks like screen scrolling and icon dragging.
Innovation Solution
The input device incorporates a display with protrusions along its edges and a detection region, where the operation input is enabled faster when aligned with the protrusions by setting specific execution conditions based on distance and movement direction, allowing for seamless continuous operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the detection region extends to the edge of the display, then the continuous operation input can be detected more accurately, but the user may stop input before reaching the edge leading to suboptimal functionality
Solution Approach 1:
The patent introduces a new dimension by adding protrusions that extend outward from the display edges. These protrusions create a spatial extension beyond the display boundary, allowing users to naturally extend their input motion into this additional space without feeling constrained by the display edge, thereby resolving the contradiction between detection accuracy and user input effectiveness
2Measurement precision
If the function is enabled only after reaching the edge of the display, then the operation input is more precise, but the response time is delayed
Solution Approach 1:
The patent applies preliminary action by enabling the function before the user actually reaches the edge of the display. The protrusions are positioned such that when the user's input touches or approaches the protrusion (which extends beyond the display edge), the function is immediately enabled. This allows the system to anticipate and prepare for the edge-reaching action, reducing response time while maintaining precision
3Speed
If protrusions are added along the outer edge of the display, then the continuous operation input in the direction of protrusion is enabled faster, but the device structure becomes more complex
Solution Approach 1:
The patent segments the edge enhancement function by adding discrete protrusions at specific locations along the display edges rather than creating a continuous complex structure. Each protrusion is an independent element that can be detected individually, allowing the system to achieve fast function enablement through simple geometric features without requiring complex overall device restructuring

AI summary
An input device includes a display on which an operation screen is displayed, at least one protrusion displayed along an outer edge of the display, and a detector in which a display region of the display is set as a detection region. In a case where a continuous operation input in a direction provided with the protrusion is detected, a function corresponding to the continuous operation input is enabled faster than in a case where a continuous operation input in a direction different from the direction is detected.
