Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple predefined gestures are used to execute diverse functions, then functional versatility is improved, but user memorization burden increases
Solution Approach 1:
The system provides real-time feedback by displaying candidate trajectory suggestions as the user performs a gesture. The computing device continuously compares the user's current gesture path with stored executive trajectories and presents matching options, allowing users to see what functions are available based on their current input direction without needing to memorize all possible gestures in advance.
Solution Approach 2:
The system performs preliminary action by pre-storing multiple executive trajectories and their associated functions in the memory device. When a user starts a gesture, the system proactively identifies and displays candidate trajectories that match the user's current path, preparing multiple function options before the user completes their gesture, thus reducing the need for users to remember all possible gestures.
2Ease of operation
If simple gesture paths are used, then ease of operation is improved, but functional diversity is limited
Solution Approach 1:
The system implements universality by allowing a single gesture path to serve multiple functions. When the user's gesture trajectory matches multiple stored executive trajectories, the system displays all matching candidate functions, enabling one simple gesture path to execute diverse functions depending on which candidate the user selects or which function becomes active.
Solution Approach 2:
The system applies parameter changes by varying the functional outcome based on the gesture's trajectory parameters. Even with a simple gesture path, changing subtle parameters such as the exact angle, curvature, or endpoint of the gesture can match different executive trajectories in the stored set, thereby accessing different functions while maintaining gesture simplicity.
3Measurement precision
If precise gesture recognition is implemented, then measurement precision is improved, but system complexity increases
Solution Approach 1:
The system applies partial action by comparing only the relevant portions of the user's gesture path with stored executive trajectories. Rather than requiring exact matching of the entire gesture sequence, the system identifies matches based on significant path segments and similarity criteria, achieving sufficient precision without implementing overly complex recognition algorithms.
Data Source
AI summary
A system has an input device for collecting gesture information of a user, a computing device for processing the gesture information collected by the input device, a memory for storing information of executive trajectories for executing various functions, and an output device for displaying the information processed by the computing device, wherein each executive trajectory is defined as an executive input for each function, if a gesture performed by the user completes one of the executive trajectories, a function corresponding to the corresponding executive trajectory is executed, wherein, if the user starts a gesture, the computing device compares a path of a trajectory of a gesture performed by the user with start paths of the executive trajectories and selects candidate trajectories having similarity higher than a preset criterion, and wherein the candidate trajectories are displayed by the output device to suggest path information of the candidate trajectories to the user.
