Dynamic Operation Panel Display Control for Video Reproduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video reproduction controlling systems face operability issues due to unnecessary display of operation panels, which complicates user interaction and inefficiently utilizes display space, as the presence of operation inputs does not always correlate with the need for the operation panel.
Innovation Solution
A video reproduction controlling program that dynamically manages the display of operation panels based on user input requests, determining whether an operation panel is required during video content reproduction, and only displays it when necessary, thereby improving operability and optimizing display area usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operation panel is displayed whenever there is an operation input from the input device, then the user can perform operations, but the display area is constrained and the interface becomes cluttered when the operation panel is not needed
Solution Approach 1:
The operation panel is implemented as a dynamic display element that appears and disappears based on real-time detection of operation inputs. The display control unit dynamically adjusts the operation panel's visibility according to whether operation inputs are detected from the input device, making the interface adaptive rather than static. This resolves the contradiction by allowing the operation panel to occupy display space only when needed for operations.
Solution Approach 2:
The operation panel is extracted as a separate, independently controllable display element from the main video content display. By separating the operation panel display control from the video content display, the system can selectively show or hide the operation panel without affecting the video content, thus freeing up display area when the operation panel is not required while maintaining ease of operation when it is needed.
2Ease of operation
If the operation panel is displayed continuously to ensure operation availability, then operations can be performed at any time, but the display becomes cluttered and other information cannot be displayed
Solution Approach 1:
The system implements periodic detection of operation inputs from the input device and adjusts the operation panel display accordingly. Rather than continuous display, the operation panel is shown periodically only when operation inputs are detected, and hidden when no operations are needed. This periodic display approach maintains operation availability while reducing interface clutter and complexity.
3Adaptability or versatility
If the operation panel is displayed when operation inputs are detected, then the interface responds to user actions, but the display area is inefficiently used when operations are not required
Solution Approach 1:
The display control unit implements a feedback mechanism where it continuously monitors operation inputs from the input device and adjusts the operation panel display based on this feedback. When operation inputs are detected, the feedback loop triggers the operation panel to be displayed; when no operation inputs are detected, the panel is hidden. This feedback-based adaptability optimizes display area utilization by showing the operation panel only when user interaction is occurring.

AI summary
A game apparatus as a video reproduction controlling apparatus includes a CPU, and the CPU executes a reproduction control of a DVD. In the middle of reproducing the DVD, a content such as an video, a voice, etc. are reproduced. In a case that a reproduction operation such as pause, reproduction, fast reverse, fast forward, heading, etc. is not prohibited, in response to an instruction of the reproduced screen displayed on the monitor with a controller, an operation panel for reproduction operation is displayed. On the other hand, while a menu is reproduced or in a case that a screen button is displayed in accordance with the reproduction, the reproduction operation is prohibited, and even if the reproduced screen is instructed with the controller, the operation panel is not displayed.
