Spatially Aware Control Device for Pointer-Based Camera Framing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional presentation systems struggle to seamlessly integrate physical objects or subjects of interest in a hybrid meeting or presentation, as the camera remains focused on the presenter holding a tracked device, preventing remote viewers from seeing other relevant objects or subjects without manual manipulation.
Innovation Solution
A control device equipped with a processor, communication, positional, and orientation sensors, along with a ranging device, determines pointer information to adjust the field of view (FOV) of a base device, such as a camera, to track and record both the presenter and physical objects of interest based on positional and vector information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the camera remains focused on the presenter holding a tracked device, then the presenter can be continuously captured, but remote viewers cannot see other relevant objects or subjects without manual manipulation
Solution Approach 1:
A control device acts as an intermediary between the presenter and the camera system. This control device includes sensors (positional, orientation, ranging) that detect the presenter's location and gestures, and communicates with the base device to automatically adjust camera field of view. The control device mediates the interaction, enabling automatic camera control while maintaining the ability to capture both presenter and objects of interest through gesture-based pointer functionality.
2Extent of automation
If manual manipulation of the camera is required to switch between presenter and objects, then camera control precision can be maintained, but the ease of operation and automation are reduced
Solution Approach 1:
The control device performs multiple functions: it tracks the presenter's position using positional sensors, detects orientation using orientation sensors, measures distance using ranging devices, and controls camera field of view based on pointer gestures. By consolidating these diverse functions into a single control device, the system achieves high automation without proportionally increasing overall system complexity.
3Adaptability or versatility
If the camera field of view is automatically adjusted based on pointer information, then remote viewers can see objects of interest automatically, but the complexity of the control and measurement system increases
Solution Approach 1:
The control device is segmented into distinct functional components: positional sensors for location detection, orientation sensors for angle measurement, ranging devices for distance measurement, and a processor that integrates this data to control camera field of view. This segmentation allows each component to be optimized independently while working together to achieve versatile capture capability.
