Object Recognition via Lenticular Lens for Bluetooth Pairing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Bluetooth device discovery process is unintuitive and inconvenient, especially when multiple devices with similar names are present, making it difficult for users to select the correct device, especially when using smart glasses.
Innovation Solution
An object recognition method using an object recognition apparatus that receives reflected light from a recognition pattern on an object, identifies the pattern, and compares it with predefined patterns to determine the object viewed by the user, utilizing a lenticular lens to vary the recognition pattern based on the user's position and gaze.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Bluetooth device discovery is performed by displaying device names in a list, then devices can be discovered and connected, but it becomes difficult to specify the correct device when multiple devices have similar names
Solution Approach 1:
The patent introduces an intermediary element (AR display overlay) between the user and the Bluetooth device list. This intermediary provides additional visual information (such as device icons, distances, and contextual clues) that helps users distinguish between devices with similar names without changing the fundamental Bluetooth discovery mechanism.
Solution Approach 2:
The patent adds a new dimension to device identification by overlaying visual information in the user's field of view. Instead of relying solely on the one-dimensional device name list, the system provides multi-dimensional information (visual icons, spatial position, distance indicators) that enables easier device specification.
2Ease of operation
If users manually check Bluetooth device lists one by one through menu screens, then devices can be discovered, but the process becomes inconvenient when wearing smart glasses
Solution Approach 1:
The system performs device discovery and information presentation automatically without requiring manual user interaction with menu screens. The AR display automatically overlays device information in the user's field of view, enabling passive information access while the user performs other activities.
Solution Approach 2:
The system pre-processes device discovery and information extraction before the user needs to select a device. Bluetooth devices are automatically detected, and their information (names, icons, distances) is pre-prepared and overlaid in the AR display, so the user doesn't need to manually navigate through discovery processes.
3Measurement precision
If recognition patterns use different colors arranged adjacently, then object recognition accuracy improves, but the complexity of pattern identification increases
Solution Approach 1:
The patent uses color information as a key feature for object recognition. Different objects are represented by distinct color patterns or color sequences in the AR display, enabling users to quickly and accurately identify objects based on their colors without complex pattern analysis.
Solution Approach 2:
The system applies different visual qualities (colors, icons, brightness) to different parts of the display corresponding to different objects. Each object is represented with locally distinct visual characteristics that make them easily distinguishable, simplifying the overall identification process while maintaining high accuracy.

AI summary
Provided are a method and apparatus for recognizing an object. An object recognition method performed by an object recognition apparatus includes receiving reflected light in which light is reflected by a recognition pattern disposed on an object and passes through a lens, identifying the recognition pattern disposed on the object from the reflected light, and comparing the identified recognition pattern with recognition patterns defined for respective objects and determining an object viewed by a user based on a result of the comparison, wherein the recognition pattern is a pattern in which different colors are arranged adjacently.
