Video Playback Navigation Using Camera Motion Trajectory
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video play methods rely solely on a time progress bar for selecting a play location, making it difficult for users to locate video content of interest without a time cue.
Innovation Solution
Display a motion trajectory on the play interface that corresponds to the camera's path during video recording, allowing users to select a point on the trajectory to start playing the video from the corresponding image frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a time progress bar is used for selecting play location, then the video playback interface is simple, but users cannot locate video content based on spatial cues when time cues are useless
Solution Approach 1:
The patent introduces a spatial dimension to video playback by displaying the camera's motion trajectory on the playback interface. Users can interact with the trajectory to jump to specific moments based on spatial information rather than only temporal information, adding a new dimension to the traditional time-based progress bar approach.
Solution Approach 2:
The motion trajectory serves multiple functions: it provides spatial navigation cues, indicates camera movement paths, and enables users to locate interesting content based on spatial rather than temporal cues. This multi-functional element enhances the playback interface without requiring separate dedicated components.
2Adaptability or versatility
If only a time progress bar is displayed, then the interface remains simple, but users experience poor navigation when time cues are not useful
Solution Approach 1:
The system dynamically adapts the playback interface by displaying the motion trajectory based on the video content characteristics. When time cues are insufficient or useless, the spatial trajectory information becomes available to help users navigate and locate content of interest, making the interface more versatile and adaptable to different viewing needs.

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.
