Variable Display Scale Control Device With Periodic Pause
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in accurately changing display scales and playing speeds due to minor operational errors, leading to discrepancies between intended and actual scales or speeds.
Innovation Solution
A method for a variable display scale control device that uses touch panel operations, such as dragging, flicking, and long-pressing, to control the display scale and playing speed of images and music/moving picture data, where the system temporarily stops the operation at a predetermined scale/speed for a set time before resuming, ensuring natural and precise adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If continuous enlarging or reducing operations are performed without interruption, then display scale can be adjusted freely, but display scale differs from desired scale due to minor operational errors
Solution Approach 1:
The patent applies periodic action by introducing a predetermined pause duration between continuous enlarging/reducing operations. When the display scale reaches a predetermined scale, the system automatically pauses the operation for a set time before resuming. This periodic interruption allows the system to correct minor operational errors and ensure the display scale accurately reflects the user's intent, while still permitting free adjustment through continuous operations.
2Ease of operation
If continuous playing speed adjustment operations are performed without interruption, then playing speed can be changed freely, but playing speed differs from desired speed due to minor operational errors
Solution Approach 1:
The patent applies periodic action to playing speed adjustment by introducing a predetermined pause duration. When the playing speed reaches a predetermined speed, the system automatically pauses the adjustment for a set time before resuming. This ensures that minor operational errors are corrected and the playing speed accurately reflects the user's intent, while still allowing free adjustment through continuous operations.
3Measurement precision
If the operation is stopped frequently to correct errors, then display scale and playing speed accuracy improve, but operation time increases
Solution Approach 1:
The patent optimizes the balance between accuracy and time by setting a predetermined pause duration that is sufficient to correct minor operational errors but not excessively long. The pause is triggered automatically when the display scale or playing speed reaches a predetermined value, ensuring minimal interruption to the overall operation flow while maintaining accuracy.
4Loss of time
If the operation continues without pausing, then operation time is minimized, but operational errors accumulate causing scale/speed discrepancies
Solution Approach 1:
The patent introduces periodic pauses at predetermined intervals during continuous operations. These pauses are strategically timed to occur when the display scale or playing speed reaches specific predetermined values, allowing the system to verify and correct the current state without requiring continuous user intervention. This maintains high operation reliability while minimizing time loss.

AI summary
An information processing apparatus including an interface that displays an object and receives an instruction to change a display scale of the object, and a processor that controls the interface to change the display scale of the object based on the received instruction, controls the interface to stop changing the display scale of the displayed object for a predetermined period of time when the display scale of the displayed object becomes a predetermined display scale, and controls the interface to resume changing the display scale of the displayed object upon determining that the predetermined period of time has elapsed.
