Rotational AR Display Surface Using NFC for Intuitive Object Manipulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Augmented reality experiences face challenges in seamlessly integrating virtual objects with the real world, particularly in manipulating virtual objects without the need for expensive controllers or frequent recalibration, and in providing a realistic three-dimensional and multi-perspective experience without requiring users to physically move around AR markers.
Innovation Solution
A device with a rotatable main body connected to a base, equipped with a rotational mechanism and NFC technology, allowing users to manipulate virtual objects using hand gestures and detect changes in proximity, orientation, and configuration to enhance the AR experience without the need for additional hardware beyond a smartphone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If virtual objects are manipulated using controllers such as gloves, then manipulation capability is improved, but device cost and complexity increase
Solution Approach 1:
The patent introduces a camera as an intermediary device to capture real-world hand gestures and transform them into virtual object manipulation commands. Instead of requiring specialized controllers, the system uses the camera to detect hand movements and translate them into meaningful interactions with virtual objects, serving as a mediator between the user's natural gestures and the digital environment.
Solution Approach 2:
The patent replaces complex mechanical controller systems (such as data gloves with sensors and actuators) with an optical detection system using a camera. This substitution eliminates the need for expensive mechanical controllers while maintaining manipulation capability, as the camera captures visual information about hand gestures and processes them into control signals.
2Adaptability or versatility
If users physically move around AR markers to view virtual objects from different perspectives, then viewing angles are improved, but user convenience deteriorates
Solution Approach 1:
The patent adds a temporal dimension to the viewing experience by capturing multiple perspectives over time. Instead of requiring spatial movement around the AR marker, the system captures images from different angles as the marker rotates or as the camera moves, allowing users to view virtual objects from multiple perspectives by simply observing the progression of captured images rather than physically relocating.
Solution Approach 2:
The system performs preliminary capture of multiple viewing angles in advance by continuously capturing images as the AR marker rotates or the camera moves. This preliminary action stores multiple perspectives ready for playback, allowing users to access different viewing angles without needing to physically move to those positions during the viewing experience.
3Reliability
If AR markings are used to fix virtual objects to real spatial positions, then spatial integration is improved, but manipulation flexibility deteriorates
Solution Approach 1:
The patent introduces dynamic rotation of the AR marker itself to enable manipulation. Instead of requiring users to move their hands or the camera to change viewing angles, the AR marker rotates dynamically, bringing different sides of the virtual object into view. This dynamic behavior maintains the spatial anchor provided by the AR marking while adding flexibility for multi-perspective viewing and interaction.

AI summary
A device for displaying AR markings comprising a top and a base, with the top rotatably attached to the base, and the base configured to be held by a hand or placed on a fixed surface. The AR markings are positioned on the top such that when the top rotates with respect to the base, so do the AR markings. When the AR markings are scanned by an appropriate scanning and display device, such as a smart phone, a 3d image associated with the AR markings will be displayed on the display device as an augmented reality projection. When the top rotates with respect to the base, so too does the augmented reality projection.
