AI Technical Summary

Technical Problem

In augmented reality (AR) and virtual reality (VR) systems, slippage or reattachment of head-mounted devices (HMDs) can affect the accuracy of gaze input, leading to inaccuracies in user interactions due to offsets in translational, scaling, or rotational positions.

Method used

The system detects a user's gaze trajectory and recalibrates the interaction mode by compensating for offsets using dynamic UI elements with known movement patterns, matching gaze trajectories with display trajectories to ensure accurate selection despite HMD slippage.

Benefits of technology

This approach enhances interaction accuracy by seamlessly adjusting to HMD slippage, reducing the need for extensive recalibration and maintaining precise user input in AR/VR environments.

Abstract

A slippage-insensitive user interface (UI) may consider movement due to slippage, re-wearing, etc. of a head-mounted display (HMD) device when processing user gaze input. The slippage-insensitive UI may include multiple UI elements. Each UI element may have a unique movement pattern that defines the display trajectory of the UI element, thereby providing differentiation between the UI elements. The user's scan path may be matched with one of the display trajectories of the UI elements, and the corresponding UI element may be identified as a target UI element intended to be selected by the user. Eye-to-screen calibration of the HMD may be achieved using translational, scaling, and rotational offsets between the scan path and the display trajectory of the target UI element.
