Terminal Drawing Focus Positioning and Canvas Zoom Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face tedious and inefficient drawing processes on terminal devices due to the need for manual zooming and dragging to find a drawing focus, leading to low drawing efficiency and flexibility, especially when switching between distant drawing objects.
Innovation Solution
A method and device that automatically position a drawing focus based on user operations, such as selecting, lowering, or hovering the pen, and process the drawing content accordingly, including zooming, switching between objects, and adjusting the canvas resolution, to enhance user interaction and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual zooming and dragging operations are used to find drawing focus, then the user can navigate the canvas, but the operations become tedious and drawing efficiency decreases
Solution Approach 1:
The system automatically determines the drawing focus based on pen position and drawing operations without requiring manual navigation. The terminal performs self-service by autonomously adjusting the canvas view to center on the detected drawing focus, eliminating the need for users to manually zoom and drag to find their intended drawing location.
Solution Approach 2:
The system dynamically changes display parameters (zoom level, canvas position) based on detected pen operations. When the pen is lowered or hovered, the system automatically adjusts the viewing parameters to focus on the relevant area, transforming static manual navigation into dynamic automatic parameter adjustment.
2Loss of information
If manual zooming and dragging operations are performed frequently to check drawing effects, then the user can review progress, but drawing inspiration is easily interrupted
Solution Approach 1:
The system performs preliminary action by pre-detecting the user's drawing intent through pen hovering or lowering operations before the actual drawing begins. By anticipating where the user wants to draw next, the system proactively adjusts the view in advance, so when the user starts drawing, the canvas is already optimally positioned, eliminating the need for interruptive zooming and dragging during the creative flow.
3Manufacturing precision
If the canvas is zoomed in to draw local details, then drawing precision improves, but the user loses overview of the entire drawing
Solution Approach 1:
The system implements dynamic canvas viewing where the zoom level and focus area automatically adjust based on real-time pen position and drawing operations. The canvas transitions smoothly between overview and detail views, maintaining both global context and local precision as needed. This dynamic adaptation allows users to draw details with precision while the system manages the trade-off between zoom level and overall context visibility.
4Adaptability or versatility
If the user needs to switch between distant drawing objects, then all drawing objects can be accessed, but the operation process becomes inconvenient
Solution Approach 1:
The system uses feedback from pen position and drawing operations to automatically determine which drawing object the user intends to work on. By monitoring the pen's proximity to different objects and the nature of drawing operations, the system provides automatic focus switching between objects, eliminating the need for manual navigation to distant objects and making object switching convenient regardless of their separation on the canvas.
