Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If video is composited into slides of a presentation, then video can be displayed in presentations, but relatively high amounts of computational resources are required
Solution Approach 1:
The system separates live video feed processing from slide composition by using independent video layers that do not require full composite rendering. The live video is processed as a separate layer that can be overlaid on slides without requiring the entire slide deck to be re-composited, reducing computational overhead.
Solution Approach 2:
The system uses mirror feeds from external devices to create live video representations without requiring full video capture and processing. By mirroring existing display outputs from external devices, the system avoids redundant video encoding and processing steps that would consume additional computational resources.
2Ease of manufacture
If video is composited into slides of a presentation, then video can be displayed in presentations, but the use of live video is precluded
Solution Approach 1:
The system implements dynamic layering where live video feeds and slide content exist as separate, independently controllable layers. This allows the presentation to dynamically switch between static slide content and dynamic live video feeds, and to overlay them in various configurations without requiring full re-composition, thereby supporting both traditional and live video modes.
Solution Approach 2:
The presentation system is designed to handle multiple video sources and modes universally. It can process traditional video files, live camera feeds, and mirror feeds from external devices through a unified interface, allowing the same system to support both pre-recorded video and live video without requiring separate processing pipelines.
3Productivity
If traditional video compositing methods are used, then video can be displayed, but the cognitive burden on users increases and efficiency decreases
Solution Approach 1:
The system automatically manages video feed integration and layering without requiring users to manually composite each video element. The presentation software handles video source selection, layer positioning, and synchronization automatically, reducing the cognitive burden on users while maintaining full video functionality.
4Reliability
If complex video processing is performed, then video quality can be maintained, but power consumption increases and battery life decreases
Solution Approach 1:
The system extracts only the essential video data needed for display by using mirror feeds that capture existing display outputs from external devices. This approach takes out the redundant processing steps of full video capture, encoding, and compression, maintaining visual fidelity while significantly reducing the computational power and energy consumption required.

AI summary
The present disclosure generally relates to providing live video. An example method includes, at a computer system, while in an editing mode for a presentation, receiving, via one or more input devices, a request to insert an object onto a first slide of the presentation, wherein the request includes associating the object with a source for live video; and while in a presentation mode for the presentation, displaying, via a display generation component, the first slide including concurrent display of the object and one or more visual elements, wherein: in accordance with a determination that the object is associated with a camera, the object includes a live video stream from the camera; and in accordance with a determination that the object is associated with a non-camera external device, the object includes a live video stream that mirrors a portion of a display of the non-camera external device.
