Rotational Projector and Camera Mechanism for Dynamic Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current stand-alone devices primarily rely on voice interaction for user communication, limiting their ability to engage users through more dynamic and interactive methods, such as visual and gesture recognition.
Innovation Solution
A mechanical system integrating a rotational projector and RealSense camera, allowing independent rotation of the projector and camera components, which captures images to determine a suitable projection surface and adjusts the projector's position for optimal image projection, utilizing stepping motors and photo interrupter sensors for precise control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If stand-alone devices rely on voice interaction only, then device complexity is reduced, but user engagement capability and interaction versatility are limited
Solution Approach 1:
The patent combines voice interaction capabilities with visual projection and camera systems into a single stand-alone device. The projector and camera are integrated with the computing device, allowing the system to both project images and capture gestures simultaneously, thereby enhancing user engagement without requiring multiple separate devices
Solution Approach 2:
The device is designed to perform multiple functions: voice communication, visual projection, gesture recognition, and image capture. This multi-functionality allows a single device to replace what would traditionally require multiple separate devices, improving versatility while managing complexity through unified hardware and software architecture
2Adaptability or versatility
If the projector and camera are fixed in position, then device structure is simplified, but the ability to dynamically adjust projection location and capture surrounding area is limited
Solution Approach 1:
The projector and camera are mounted on rotational mechanisms that allow them to move independently relative to each other and the base device. The projector can rotate to point at different locations, and the camera can rotate to capture different areas of the surrounding environment, providing dynamic adaptability
Solution Approach 2:
The device is divided into distinct rotational segments: a base device portion, a projector portion that can rotate independently, and a camera portion that can also rotate independently. This segmentation allows each component to be positioned optimally for its specific function without constraining the others
3Measurement precision
If the camera captures images to determine projection surface, then projection accuracy is improved, but processing time and system response time increase
Solution Approach 1:
The camera continuously captures images of the surrounding area, and the system pre-processes this visual data to identify potential projection surfaces in advance. This preliminary action allows the system to have projection surface information ready before the user initiates a projection request, reducing overall response time
Solution Approach 2:
The system uses the camera to continuously monitor the environment and provides feedback about detected surfaces and obstacles to the projection system. This real-time feedback loop allows the projector to dynamically adjust its operation based on the current environment, improving both accuracy and responsiveness
