Solution Overview
Problem
Existing methods for interacting with system user interfaces in augmented and virtual reality environments are cumbersome, inefficient, and create a significant cognitive burden on users, requiring extensive input and providing insufficient feedback, which wastes energy and detracts from the experience.
Innovation Solution
A computer system that utilizes attention-based methods, such as directing attention to a hand location, hand orientation, and body pose to invoke controls and interfaces, reducing the need for traditional inputs and enhancing user interaction efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional input methods are used to interact with system user interfaces in augmented/virtual reality environments, then the interfaces can be accessed, but the interaction becomes cumbersome and creates significant cognitive burden on users
Solution Approach 1:
The patent replaces traditional mechanical input devices (controllers, joysticks, keyboards) with a camera-based optical system that detects hand gestures and body movements in three-dimensional space. This substitution eliminates the need for physical interaction with complex input devices, thereby improving ease of operation while reducing the perceived complexity for the user.
Solution Approach 2:
The system enables users to interact with interfaces using their natural hand gestures and body movements without requiring learning or adaptation to specialized controls. The camera automatically tracks and interprets these natural movements, allowing the system to serve itself by converting organic human motion into meaningful input commands, thus simplifying the interaction model.
2Productivity
If extensive input is required to invoke system user interfaces, then precise control can be achieved, but the interaction takes longer and wastes energy
Solution Approach 1:
The system continuously tracks hand gestures and body movements in real-time using the camera, maintaining a ready state that can immediately recognize and respond to interface invocation gestures. This preliminary tracking eliminates the need for users to perform multiple sequential input steps, allowing instant invocation of system interfaces and significantly reducing interaction time.
Solution Approach 2:
The patent implements gesture-based shortcuts that allow users to bypass traditional multi-step interface invocation processes. By recognizing specific hand gestures in three-dimensional space, the system can directly trigger interface actions without requiring users to navigate through intermediate steps, thereby rushing through the interaction process and improving productivity.
3Measurement precision
If multiple input steps are required to display system user interfaces, then control precision can be maintained, but user cognitive burden increases
Solution Approach 1:
The patent transitions from two-dimensional screen-based interaction to three-dimensional gesture recognition in physical space. The camera captures hand gestures and body movements along the Z-axis, adding a spatial dimension to input recognition. This dimensional expansion allows for more intuitive and natural gestures that are easier to perform and remember, reducing cognitive burden while maintaining precise gesture recognition through spatial coordinates and motion trajectories.

AI summary
While a view of an environment is visible, a computer system detects that attention of a user is directed toward a location of a hand of the user, and in response: in accordance with a determination that the attention of the user is directed toward the location of the hand while first criteria are met, wherein the first criteria include a requirement that the hand is in a respective pose and oriented with a palm of the hand facing toward a viewpoint of the user in order for the first criteria to be met, the computer system displays a control corresponding to the location of the hand; and in accordance with a determination that the attention of the user is directed toward the location of the hand while the first criteria are not met, the computer system forgoes displaying the control.
