Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pointer-based multi-step selection interfaces are cumbersome and error-prone, especially in unsteady or high-stress environments, as they require users to navigate through numerous options, leading to inefficient and inaccurate selections.
Innovation Solution
A multi-step selection interface that minimizes pointer movement by rendering menus in a single direction and displacing them perpendicularly, allowing for convenient revision and recall of previous selections, with high-probability options positioned for easy access, reducing cognitive load and improving navigation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a pointer-based interface requires users to navigate through numerous options directly, then the selection accuracy may improve, but the time required and user fatigue increase significantly
Solution Approach 1:
The patent divides a large set of options into multiple hierarchical levels or categories. Users first select a category, then a subcategory, and finally a specific item. This segmentation reduces the number of options presented at each step, making navigation faster and more accurate without requiring users to scroll through or point to items in a massive list.
Solution Approach 2:
The patent introduces additional dimensions for selection beyond a single linear list. Instead of navigating one long dimension (a vertical or horizontal list of all items), users navigate through multiple dimensions (categories, subcategories, attributes) to reach the desired item. This multi-dimensional approach reduces the path length and cognitive load compared to direct navigation through a flat list.
2Productivity
If a multi-step selection process is implemented to reduce the number of choices at each step, then the selection speed improves, but the interface complexity increases
Solution Approach 1:
The patent employs a universal selection mechanism that handles multiple selection steps through a consistent interaction pattern. The same input method (e.g., directional control, scrolling, or pointing) is used across all selection levels, reducing the need for users to learn different controls for different parts of the interface. This universality masks the underlying complexity while maintaining high selection speed.
Solution Approach 2:
The patent implements nested selection structures where categories contain subcategories, which contain specific items. Each level is contained within the previous level, creating a hierarchical nesting pattern. This nesting allows the interface to manage complexity by organizing options in concentric layers, where users progressively narrow down choices without encountering the full complexity of all options simultaneously.
3Measurement precision
If successive filters are applied to narrow down choices in a command and control interface, then the selection accuracy improves, but the number of steps required increases
Solution Approach 1:
The patent applies filters and categories in a predetermined hierarchical order based on the most effective narrowing strategy. Common or high-probability filters are applied first to quickly eliminate large portions of the option set. This preliminary action reduces the search space before users begin their selection process, improving accuracy without adding unnecessary steps.
Solution Approach 2:
The patent implements dynamic filtering where the available options and active filters adapt based on user selections and context. As users make selections at each level, the subsequent filters and options are dynamically adjusted to remain relevant. This dynamic behavior allows the system to maintain precision while minimizing the number of steps by adapting to user needs in real-time rather than following a rigid multi-step sequence.

AI summary
A method for a multi-step selection interface is provided including receiving a multistep selection indication, causing, using a processing circuitry, a first selection menu extending in a first direction to be rendered on a display, receiving a first selection indication based on the first selection menu, in response to receiving the first selection indication; causing a second selection menu to be rendered on the display, extending in the first direction in substantially the same position of the display as the first selection menu, and causing a rendering of at least a portion of the first menu to be displaced in a direction substantially perpendicular to the first direction.
