Video Playback Using Camera Motion Trajectory Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video playback methods rely solely on a time progress bar for selecting play locations, making it difficult to locate video content not related to time cues.
Innovation Solution
Displaying a motion trajectory of the video recording synchronized with video playback, allowing users to select play points based on spatial cues by correlating video frames with points on the motion trajectory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If only a time progress bar is used for selecting play locations, then the device complexity is low, but the ease of operation deteriorates when users need to locate non-time-related video content
Solution Approach 1:
The patent introduces a spatial dimension (motion trajectory) to the traditional time-based progress bar. By displaying the camera's movement trajectory as a visual path that users can interact with, the system adds a spatial selection dimension alongside the existing time dimension, enabling users to locate video content through spatial cues such as movement direction, speed changes, or location-based landmarks rather than relying solely on time markers.
2Ease of operation
If a motion trajectory is added to the playback interface, then the ease of operation for locating video content improves, but the device complexity increases
Solution Approach 1:
The motion trajectory serves multiple functions simultaneously: it visualizes the camera's movement path for contextual understanding, acts as an alternative selection mechanism for jumping to specific video segments, and provides spatial orientation cues. This multi-functionality justifies the added interface complexity by delivering multiple operational benefits from a single visual element.
Solution Approach 2:
The patent creates a visual copy or representation of the physical camera movement trajectory and displays it on the screen. This graphical representation mirrors the actual motion path taken during video recording, allowing users to interact with the trajectory visualization to select and jump to specific video segments corresponding to particular moments in the recorded motion.

AI summary
This application discloses a video play method and apparatus and an electronic device, and pertains to the field of video play technologies. The video play method includes: displaying a motion trajectory on a play interface of a target video when the target video is played, where the motion trajectory is a motion trajectory of a camera when photographing the target video, and points on the motion trajectory correspond to image frames in the target video; receiving a first input of a user for a target point on the motion trajectory; and in response to the first input, controlling the target video to start playing from an image frame corresponding to the target point.
