Wireless Presentation Control via Central Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Presenters face challenges in remotely controlling and accessing presentations across different locations, especially when they need to move freely during a presentation, and existing methods require carrying physical media or complex equipment setups.
Innovation Solution
A system and method for preparing and presenting electronic presentations stored on a central server, allowing access and control via an internet-enabled wireless device, enabling remote control of presentations through a mobile device, even if the presentation equipment belongs to another party, using standard web browsers and networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If presentations are stored on physical media (CD-ROM, DVD-ROM, or portable memory devices), then the presentation can be transported to remote locations, but the presenter must carry and manually set up physical equipment
Solution Approach 1:
The presentation is copied to a central server accessible over the internet, replacing physical media. The presenter accesses the presentation remotely through a web browser on a mobile device, eliminating the need to carry physical disks or memory devices. The server maintains the master copy while allowing remote access and control.
Solution Approach 2:
The mechanical system of physically transporting and connecting presentation equipment is replaced with an electronic network-based system. Instead of manually plugging in cables and setting up projectors, the presenter uses wireless network communication and a web browser interface to access and control the presentation remotely.
2Ease of operation
If the presenter uses a laptop computer with presentation software, then the presentation can be controlled locally, but the presenter must locate electrical outlets and video cables at the presentation site
Solution Approach 1:
The system provides universal access to presentations through web browsers, which are available on virtually all modern devices including smartphones, tablets, and computers. This eliminates the need for specialized presentation software and allows the presenter to control presentations from any internet-connected device in any environment.
Solution Approach 2:
The central server acts as an intermediary between the presenter's mobile device and the presentation display system. The server receives control commands from the presenter's device and manages the presentation delivery, eliminating the need for the presenter to physically connect their laptop to the presentation equipment.
3Adaptability or versatility
If the presentation equipment belongs to another party, then the organization can provide presentation facilities, but the presenter cannot easily control or access the presentation
Solution Approach 1:
The central server acts as an intermediary that bridges the presenter's mobile device and the external presentation equipment. The server receives control commands from the presenter and manages the presentation delivery to the external display system, allowing full control without physical connection to the equipment.
Solution Approach 2:
The physical connection requirements between presentation software and display equipment are replaced with network-based communication. The presenter controls the presentation through wireless network commands sent to the server, which then manages the display on external equipment regardless of ownership or location.
4Ease of operation
If the presenter needs to move freely through the room during presentation, then the presenter can engage with the audience, but the presenter cannot easily control the presentation without being tethered to equipment
Solution Approach 1:
The physical tether of cables connecting the presenter's laptop to the presentation equipment is replaced with wireless network communication. The presenter can move freely while the mobile device maintains network connectivity, allowing presentation control without physical constraints.

AI summary
In general, the subject matter described in this specification can be embodied in methods for accessing a presentation stored on a remote server with a first computing device that is connected to the remote server over a network. The first computing device communicates with the network over a wireless connection. The first computing device is used to cause a second computing device to display the presentation. The second computing device is connected to the remote server over a network. The display of the presentation is substantially controlled with communication between the first computing device and the second computing device. The communication occurs only through the remote server.
