Information Processing Device Automatic Slide Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Participants in a presentation setting often struggle to manually switch between slides on their devices in sync with the presenter, leading to ineffective utilization of presentation materials.
Innovation Solution
An information processing device equipped with a display unit, information providing unit, and display switch unit that automatically transmits second information to a host computer when the onscreen representation is switched, allowing client devices to synchronize image changes with the presenter's device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If participants manually operate their portable devices to switch slides, then they can view presentation materials, but they cannot effectively utilize the materials when focusing on the lecture
Solution Approach 1:
The system enables self-service by having the presenter's device automatically control the portable devices of participants. When the presenter switches slides on their device, the same slide automatically appears on participants' devices without requiring manual intervention from participants, thus resolving the contradiction between ease of operation and effective utilization.
Solution Approach 2:
The portable device acts as an intermediary between the presenter's device and the presentation materials. It receives control signals from the presenter's device and automatically displays the corresponding slides, eliminating the need for participants to manually operate their devices while ensuring they view the correct presentation materials.
2Adaptability or versatility
If participants manually switch slides on their devices, then they can access presentation materials, but they may fail to switch to proper images when focusing on the lecture
Solution Approach 1:
The system implements feedback by having the presenter's device transmit slide switching information to participants' portable devices. This automatic feedback mechanism ensures that participants' devices always display the correct slide corresponding to what the presenter is showing, eliminating synchronization errors that occur with manual switching.
Solution Approach 2:
The portable device serves as an intermediary that automatically receives and displays slide information from the presenter's device. This intermediary function ensures reliable synchronization between the presenter's slides and participants' displays without requiring participants to manually track slide changes.
3Productivity
If a WWW server is installed for large conference rooms, then participants can connect portable devices to browse image files, but participants need to manually operate to switch slides
Solution Approach 1:
The system transforms the manual operation requirement into a self-service system where the presenter's device automatically controls participants' portable devices. The portable devices automatically receive and display slide information without requiring participant intervention, thus improving ease of operation while maintaining the ability to browse presentation materials.
Solution Approach 2:
The portable device acts as an intermediary between the WWW server and the presentation materials. It automatically receives slide information from the presenter's device and displays it, eliminating the need for participants to manually navigate or switch slides while still providing access to presentation materials through the server infrastructure.
