Wearable Video Orientation via Head Motion Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wearable computing systems, users face disruptions or burdens when trying to change the orientation of video data streamed between devices, requiring verbal communication or other cumbersome methods to adjust the camera orientation.
Innovation Solution
A system and method that includes an image-capture device and a non-transitory computer-readable medium with program instructions to receive and send video data, allowing users to adjust the camera orientation based on head movements detected by sensors, synchronizing the video feed between devices through graphical displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If video data is streamed between wearable devices, then real-time communication is enabled, but adjustment of video orientation becomes cumbersome requiring verbal communication
Solution Approach 1:
The system automatically detects the wearer's head orientation using sensors (accelerometer, gyroscope, magnetometer) and adjusts the video feed orientation accordingly without requiring manual input. The processor continuously monitors sensor data and transforms video coordinates based on detected head position, enabling the system to self-adjust to user needs
Solution Approach 2:
The system implements a feedback loop where sensor data from the wearable device continuously informs video orientation adjustments. The processor receives orientation data from sensors, processes this information to determine required video transformation, and applies coordinate transformations to align the video feed with the wearer's current head orientation, creating a closed-loop adaptive system
2Loss of information
If verbal communication is used to adjust video orientation, then communication between users is possible, but interaction becomes disruptive and burdensome
Solution Approach 1:
The patent replaces the mechanical/verbal communication method with an automated sensor-based system. Instead of requiring users to verbally communicate orientation changes, the system uses inertial sensors (accelerometer, gyroscope, magnetometer) to detect head orientation and automatically adjusts video feed accordingly, eliminating the need for disruptive verbal interaction
Solution Approach 2:
The system introduces sensors and a processor as intermediaries between the user's natural head movements and the video feed orientation. The sensors detect head position, the processor interprets this data and calculates required transformations, and applies coordinate changes to the video feed, creating a seamless intermediary layer that translates physical movement into visual adjustment without requiring direct user intervention

AI summary
Methods and systems involving the orienting of video data based on the orientation of a display are described herein. An example system may be configured to (1) receive first video data, the first video data corresponding to a first orientation of the image-capture device; (2) send the first video data to a second computing device; (3) receive, from the second computing device, first orientation data indicating a requested orientation of the image-capture device; (4) cause a visual depiction of the requested orientation to be displayed on a graphical display; (5) receive second video data, the second video data corresponding to a second orientation of the image-capture device, where the second orientation is closer to the requested orientation than is the first orientation; and (6) send the second video data to the second computing device.
