Head Rotation Tracking Device for Automated Video Highlight Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Viewers face challenges in capturing video highlights during sports events due to the difficulty of tracking rapid movements across large sports fields and predicting when significant events will occur, leading to fatigue and frustration from constantly monitoring the action.
Innovation Solution
A system that tracks a user's head rotation movement using a wearable device and synchronizes a video capturing device on a rotary station with the user's head rotations, allowing the device to automatically follow and capture key moments without constant user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a viewer manually tracks players and captures video highlights using a smartphone, then the viewer can capture video highlights, but the viewer experiences fatigue and frustration from constantly monitoring the action
Solution Approach 1:
The system uses the viewer's own head movements as the control signal, making the system adapt to the user's natural behavior rather than requiring the user to adapt to the system. The head tracking device automatically captures the viewer's attention direction, and the robotic arm automatically pans the camera to follow the indicated direction, eliminating manual operation while using the user's natural head movements as input
Solution Approach 2:
The patent replaces manual mechanical operation (holding and manually panning a smartphone) with an automated robotic arm system that uses electric motors and control algorithms to pan the camera based on head tracking data, substituting complex manual mechanical control with automated electromechanical systems
2Reliability
If a viewer frequently turns their head to track players across a large sports field, then the viewer can follow the action, but the viewer experiences fatigue and frustration
Solution Approach 1:
The patent introduces a head tracking device worn by the viewer as an intermediary that captures head movement data, and a robotic arm system as another intermediary that converts this data into camera pan movements. This chain of intermediaries translates the viewer's natural head movements into reliable continuous tracking of players across the field without requiring sustained manual effort
Solution Approach 2:
The system substitutes the viewer's manual head turning mechanism with an automated robotic arm pan mechanism that is driven by electric motors and controlled by algorithms processing head tracking data, replacing sustained manual mechanical action with automated electromechanical action
3Measurement precision
If a viewer stays alert for the whole sports game to predict video highlights, then the viewer can capture highlights when they occur, but the viewing experience is degraded due to fatigue and frustration
Solution Approach 1:
The system uses the viewer's own head movements as the trigger signal for capturing highlights, eliminating the need for the viewer to consciously predict when highlights will occur. The automated system interprets head movement patterns as indicators of interesting moments and automatically captures video at those moments, making the system self-serve the highlight detection function
Solution Approach 2:
The system implements feedback by continuously monitoring head tracking data and using this information to control the robotic arm's camera panning in real-time. The closed-loop feedback mechanism adjusts camera positioning based on current head movement, enabling automatic highlight detection without requiring sustained viewer alertness

AI summary
A solution is disclosed for conveniently capturing video highlights in a sports event by tracking head rotation movement of a user and synchronizing rotations of a video capturing device (e.g., the user's mobile phone) on a rotary station with the head rotation movement of the user. The user wears a rotation tracking device, which tracks the head rotation movement of the user in connection with watching an event. The head rotation data from the user's head rotation movement is filtered to generate filtered head rotation data, which excludes noise motions in the head rotation data. Corresponding rotary control data is generated based on the filtered head rotation data. The rotary control data is used to instruct a rotary system to rotate synchronously with head rotations of the user when a video capturing device mounted on the rotary system captures videos of the sports event.
