Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for interacting with widgets in XR environments are limited by lack of intuitiveness, difficulty in manipulation due to 3D spatial complexities, reliance on additional hardware, and two-dimensional interaction paradigms, leading to a less immersive and frustrating user experience, particularly for novice users.
Innovation Solution
The disclosure provides intuitive, hardware-independent techniques for interacting with XR widgets, leveraging the immersive and three-dimensional nature of XR, using hand gestures and controller operations to perform system-level and content-level controls, with visual and audio feedback based on gesture duration and distance, and incorporating real-world object interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional 2D interaction paradigms are used for XR widgets, then implementation is simpler, but user experience and immersion are degraded
Solution Approach 1:
The patent transitions from 2D interaction paradigms to 3D spatial interaction in XR environments. Widgets are positioned in three-dimensional space and interacted with using spatial gestures, eye tracking, and voice commands, transforming the interaction model from flat screens to immersive volumetric space, thereby improving user experience and immersion while managing complexity through natural intuitive controls
2Measurement precision
If additional hardware is required for widget interaction, then interaction precision may improve, but device complexity and cost increase
Solution Approach 1:
The patent utilizes the HMD's existing optical sensors for multiple purposes: primary XR rendering, hand gesture detection, and eye tracking. By making the optical sensors multi-functional, the system achieves precise gesture and gaze detection without requiring additional dedicated hardware, thereby maintaining measurement precision while avoiding increased device complexity
Solution Approach 2:
The system uses the HMD's own optical sensors to detect hand gestures and eye movements, allowing the device to serve itself for interaction detection without external add-on hardware. The optical sensors that already exist in the HMD are leveraged to provide gesture recognition and eye tracking capabilities, eliminating the need for separate sensors or controllers
3Adaptability or versatility
If 3D spatial interaction is implemented, then immersion and intuitiveness improve, but difficulty in manipulation increases due to spatial complexities
Solution Approach 1:
The patent implements visual and audio feedback mechanisms to guide users through 3D spatial interactions. Visual feedback includes highlighting interactive elements and showing gesture recognition status, while audio feedback provides confirmation of detected gestures and actions. This feedback loop helps novice users understand the spatial interaction paradigm, reducing manipulation difficulty while maintaining immersion and intuitiveness
Solution Approach 2:
The patent introduces voice commands as an intermediary for controlling widgets in 3D space. Voice commands provide a natural language interface that bridges the gap between complex spatial gestures and user intent, allowing users to issue commands without precise manual manipulation. This intermediary reduces the difficulty of 3D spatial manipulation while maintaining the immersive experience

AI summary
A method includes rendering a virtual widget at a first position in an extended reality (XR) space using a head-mounted display. The method also includes detecting a hand gesture of a user at a second position in the XR space using at least one optical sensor. The second position is between the first position and the optical sensor. The method further includes determining a duration of the hand gesture and a distance between the first and second positions. The method also includes performing a first or second type of action based on the duration and/or the distance. The first type of action corresponds to a system-level control of the virtual widget, and the second type of action corresponds to a content-level control of the virtual widget. In addition, the method includes rendering a visual and/or audio feedback based on at least one of the duration or the distance.
