Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Augmented reality experiences face challenges in seamlessly integrating virtual and real worlds, 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.
Innovation Solution
A device with a rotatable main body connected to a base, allowing for the manipulation of virtual objects using hand gestures and equipped with a motor and motion detector for automatic rotation, enabling users to interact with augmented reality without requiring 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 portability deteriorate
Solution Approach 1:
The patent introduces a camera as an intermediary device to capture real-world images and overlay virtual objects, eliminating the need for expensive specialized controllers. The smartphone camera serves as the mediator between the user and the AR system, enabling manipulation through standard mobile device interfaces rather than requiring costly gesture gloves or specialized controllers.
Solution Approach 2:
The patent makes the smartphone serve multiple functions: it acts as the camera for capturing real-world images, the display device for showing AR content, the processor for rendering virtual objects, and the manipulation interface through touchscreen controls. This multi-functionality eliminates the need for separate expensive AR controllers, as the ubiquitous smartphone handles all manipulation tasks.

3Adaptability or versatility
If users walk around the AR marker to view from different perspectives, then three-dimensional experience is improved, but convenience deteriorates
Solution Approach 1:
The patent implements dynamic rotation of the AR display surface, allowing the virtual object to rotate automatically or in response to user input. This dynamic adjustment enables users to view the virtual object from multiple perspectives without physically moving around the AR marker, maintaining the three-dimensional experience while greatly improving convenience.
Solution Approach 2:
The patent creates a virtual copy of the physical rotation experience by digitally rotating the AR display surface. Instead of requiring users to physically walk around the marker to see different angles, the system copies the effect of physical movement through digital rotation of the virtual object, providing the same multi-perspective experience without the physical constraint.
4Measurement precision
If controllers are calibrated prior to use, then manipulation precision is improved, but time consumption and complexity deteriorate
Solution Approach 1:
The patent implements automatic calibration features where the system self-adjusts based on camera feedback and user interaction patterns. The smartphone's existing sensors and camera automatically calibrate the AR experience without requiring manual setup, eliminating the time-consuming calibration process while maintaining precision through automated adjustment algorithms.

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.
