Adaptive Display Magnification for Error-Free Object Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional devices fail to prevent operating errors when display magnification is set too small, as users may inadvertently select adjacent objects or perform incorrect operations due to difficulty in selecting or confirming small objects, and existing solutions do not adequately meet user intentions for screen enlargement or reduction.
Innovation Solution
An information processing apparatus that determines executable operations based on the display size of objects, allowing only scroll operations when objects are too small for selection and enabling selection or other operations when they are sufficiently enlarged, thereby aligning with user intentions and preventing errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the display magnification is set small to allow scrolling and overviewing, then the user can scroll through content efficiently, but the operation target object becomes difficult to see and select, causing operating errors
Solution Approach 1:
The system dynamically changes the display magnification parameter based on the detected operation type. When a selection operation is detected on a small object, the magnification is automatically increased to improve visibility and selection accuracy. When scrolling is detected, the magnification remains small to maintain overview capability. This resolves the contradiction by making the display size adaptive rather than fixed.
2Reliability
If the display is automatically enlarged when objects are dense to prevent erroneous selection, then selection accuracy improves, but the user's intention to scroll and overview is not met
Solution Approach 1:
The system makes the display magnification dynamic rather than static. Instead of automatically enlarging the display when objects are dense, the system waits for the user's operation input and then dynamically adjusts the magnification based on the detected operation type and object size. This allows the system to adapt to different user intentions (scrolling vs. selection) in different contexts.
Solution Approach 2:
The system uses feedback from the user's operation input to determine whether to adjust the display magnification. By detecting the type of operation (selection vs. scrolling) and the size of the target object, the system provides appropriate feedback by adjusting the display size accordingly, rather than applying a fixed enlargement rule.
3Ease of operation
If the same input operation is allowed regardless of display magnification, then operational simplicity is maintained, but the user's specific intentions for enlargement or reduction cannot be fulfilled
Solution Approach 1:
The system makes the available operations dynamic based on the current display magnification and target object size. Instead of allowing the same operations regardless of context, the system dynamically enables or disables certain operations based on whether the target object is sufficiently large for accurate selection. This maintains simplicity for appropriate operations while enabling additional operations when conditions are suitable.
