Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional input methods are used to interact with virtual elements, then the system can process user inputs, but the interaction becomes cumbersome and creates significant cognitive burden on users
Solution Approach 1:
The system provides real-time visual feedback by deforming the surface of user interface objects in response to detected hand movements. This feedback loop allows users to understand the connection between their inputs and device responses, reducing cognitive burden and improving interaction efficiency without increasing interface complexity
Solution Approach 2:
The system automatically detects hand movements and performs operations based on detected gestures, reducing the need for users to manually navigate complex interfaces. The system serves itself by interpreting natural hand movements as commands, eliminating the need for users to learn complex input methods
2Productivity
If multiple inputs are required to achieve a desired outcome, then the system can perform precise operations, but the interaction takes longer than necessary and wastes energy
Solution Approach 1:
The system continuously monitors hand movements and prepares to execute operations as soon as gesture criteria are met. By detecting hand movements in advance and pre-processing potential commands, the system reduces the number of discrete input steps required, speeding up operation completion and reducing energy consumption from prolonged processing
Solution Approach 2:
The system maintains continuous operation by processing hand movements and executing commands without requiring users to return to home screens or perform intermediate steps. This continuous action flow eliminates idle time and redundant processing, improving productivity while reducing energy waste from repeated system state changes
3Loss of information
If the system provides detailed feedback for user inputs, then users can understand the connection between inputs and responses, but the processing requirements and energy consumption increase
Solution Approach 1:
The system provides feedback by deforming only the local surface area of user interface objects that corresponds to the detected hand movement location. This localized feedback approach maintains information completeness for the relevant interaction area while avoiding unnecessary processing and energy consumption across the entire display

AI summary
A computer system displays a view of a three-dimensional environment, including a first user interface object with a first surface at a first position, that when activated by a user input meeting first criteria, causes performance of a first operation. While displaying the first user interface, the computer system detects first movement of a hand in a physical environment, and in response, in accordance with a determination that the first movement of the hand meets second criteria without meeting the first criteria, the computer system deforms the first surface of the first user interface object at the first position, including moving a first portion of the first surface relative to a second portion of the first surface, without performing the first operation. A location of the hand in the physical environment corresponds to a location at least a first threshold distance from the first position in the three-dimensional environment.
