Spectacles - EyeConnect

Summary

The article discusses EyeConnect, a feature designed to facilitate shared augmented reality experiences by allowing users to connect their Spectacles through a novel motion tracking algorithm. Unlike traditional methods that require environmental scanning or visual fiducials, EyeConnect enables users to join sessions simply by looking at each other, leveraging a robust optimizer for 6DoF pose alignment. The system prioritizes user privacy by sharing only essential positional data and employs a dynamic-object anchoring approach to detect Spectacles in real-time. The article also contrasts EyeConnect with traditional methods, highlighting its advantages and challenges in various scenarios, including crowded environments and low-motion situations.

Key Learnings

• 1EyeConnect utilizes a unique algorithm that allows users to join shared AR experiences by simply looking at each other, significantly reducing setup time.
• 2The system employs a low-parameter convolutional neural network for detecting Spectacles, optimizing for both speed and power consumption.
• 3Egomotion Alignment is a critical mathematical foundation that simplifies the pose estimation problem by leveraging gravity alignment to reduce complexity.
• 4The algorithm's performance is evaluated based on median spatial error, demonstrating high accuracy in real-time applications despite environmental challenges.
• 5Privacy is a core consideration, with the system designed to delete all tracked data post-alignment, contrasting with traditional SLAM systems.
