Augmented Reality Apparatus Context Identification Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Incorporating video footage into the live view of a hand-held device camera is challenging due to limited processing power and lack of functional codebase in built-in frameworks, making it difficult to provide an enhanced augmented reality experience.
Innovation Solution
An apparatus and method for a hand-held device with a camera that includes a context identification unit, virtual image retrieval unit, and virtual image positioning unit to display a virtual image, which can be a moving real-world image, previously stored as a sequence of still images or continuous video, synchronized with audio, allowing for augmented reality by identifying and positioning the image based on contextual information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video footage is incorporated into the live camera view to provide augmented reality, then the user experience is enhanced, but the processing power requirements exceed the capabilities of most hand held devices
Solution Approach 1:
The system segments the augmented reality processing into distinct functional units: context identification unit for analyzing the live view, virtual image retrieval unit for selecting appropriate images, and virtual image positioning unit for placing images in the correct locations. This segmentation allows each unit to perform its specific function efficiently within the constraints of handheld device processing power.
Solution Approach 2:
The system performs preliminary actions by pre-identifying contexts and pre-positioning virtual images based on context information from the live view. The context identification unit analyzes the current scene in advance, and the virtual image positioning unit pre-calculates positioning parameters, reducing the computational burden during real-time display and maintaining smooth performance on devices with limited processing power.
2Adaptability or versatility
If multiple functional units are added to enable context identification and virtual image processing, then augmented reality capability is improved, but device complexity increases
Solution Approach 1:
The hand held device is designed with multi-functional units that perform multiple tasks. The context identification unit not only identifies contexts but also provides information to both the virtual image retrieval unit and positioning unit. The display unit integrates both the live camera view and virtual images. This multi-functionality reduces the need for separate dedicated components for each function, thereby managing device complexity while maintaining comprehensive augmented reality capability.
3Manufacturing precision
If virtual images are positioned and sized according to context information, then the realism of augmented reality is improved, but the processing requirements for image analysis increase
Solution Approach 1:
The system applies partial action by focusing context identification and image positioning efforts on the most relevant virtual images and key contextual elements. Rather than analyzing and positioning all possible virtual images with equal detail, the system prioritizes those that most significantly enhance the augmented reality experience, achieving sufficient positioning precision for the most important elements while conserving processing power for devices with limited capabilities.

AI summary
An augmented reality experience is provided to a user of a hand held device, such as a mobile phone, which incorporates an electronic processor, a camera and a display. Images taken from video footage are displayed in a display of a hand held device together with a live camera view, to create the illusion that the subject of the video—i.e., the virtual moving image—is present in the field of view of the camera in real time. In this context the term “real world” image means an image taken from reality, such as a physical, real-world scenario using an electronic photo-capture technique, e.g. video recording. A camera of a hand held device is aimed at a well-known object, which is recognisable to the device. A moving virtual image of an actor playing the part of an historical figure, chosen because of its relevance to the object, is displayed.
