Unified Mobile Video Window for Multi-Camera Map Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile apps require users to switch between app windows or use multiple devices to view and record simultaneous content, leading to delays and increased power consumption, which affects user satisfaction and retention.
Innovation Solution
A mobile application that stitches together video feeds from multiple cameras and a map overlay into a single window, allowing simultaneous display and recording, with optional automatic triggering for event capture, using a GPU for processing to reduce CPU load and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple app windows are displayed simultaneously using split screen functionality, then the user can view multiple apps at the same time, but the apps are not displayed within a single unified window and require separate window management
Solution Approach 1:
The patent combines multiple app windows (camera app and map app) into a single unified window that displays both applications simultaneously. This merging eliminates the need for separate window management while maintaining the ability to view multiple apps at once, directly resolving the contradiction between ease of operation and device complexity.
2Loss of time
If the user manually switches between app windows, then only one app is active at a time, but this causes delays in displaying information when switching from suspended or background state to active state
Solution Approach 1:
The patent maintains continuous display of both camera and map apps within a single window, eliminating the need to switch between apps. This continuity ensures that information from both applications is always accessible without delay, as neither app needs to transition from suspended or background state to active state.
3Productivity
If conventional mobile apps require user instruction to record, then recording can be controlled, but the user cannot capture record-worth events quickly enough as they occur
Solution Approach 1:
The patent implements automatic recording functionality that captures events without requiring user instruction. The system proactively records when specific conditions are met (such as detecting a record-worth event), ensuring timely capture of important moments while eliminating the delay associated with manual recording initiation.
4Ease of operation
If multiple apps are displayed simultaneously using split screen, then both apps are visible, but power consumption increases due to running multiple active applications
Solution Approach 1:
The patent merges multiple apps into a single unified window rather than running them as separate simultaneous applications. This approach allows both camera and map content to be displayed together while reducing power consumption, as the unified window structure optimizes resource usage compared to maintaining multiple independent app instances.

AI summary
A method of simultaneously displaying a first video feed, a second video feed, and a map overlay within a single window that is generated by a mobile application includes identifying, using the mobile application that is stored in a mobile device, the first video feed that is generated by a front-facing camera; identifying, using the mobile application, the second video feed that is generated by a rear-facing camera; generating, using the mobile application, the map overlay using location data of the mobile device; creating, using the mobile application and a GPU of the mobile device, the single window that includes the first video feed, the second video feed, and the map overlay; displaying, on UI and using the mobile application, the single window; recording, using the mobile application, the displayed single window; and storing the recording of the displayed single window as a single video file.
