Touchscreen Slide Control for Camera Parameter Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touchscreen-based systems for adjusting shooting parameters on electronic devices, such as smartphones and tablets, suffer from excessive operation hierarchies and low efficiency, requiring multiple steps to adjust parameters like exposure compensation and focus, leading to cumbersome user experiences.
Innovation Solution
A method and device that display a slide adjusting control centered on a click position, allowing users to adjust shooting parameters via a sliding touch signal, simplifying the process by eliminating the need for multiple button clicks and menu navigations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users adjust shooting parameters by clicking buttons on a touchscreen to trigger drop-down menus, then shooting parameters can be adjusted, but the operation process becomes complex with excessive operation hierarchies and low efficiency
Solution Approach 1:
The patent merges the parameter adjustment function directly into the touchable area of thefinder frame, combining what were previously separate operations (clicking a button to open a menu, then adjusting the parameter) into a single direct interaction. The sliding control is embedded within the finder frame itself, allowing users to adjust parameters without leaving the main shooting interface or navigating through multiple menu levels.
Solution Approach 2:
The patent introduces a sliding control as an intermediary element that mediates between the user's touch input and the parameter adjustment. This sliding control acts as a direct mediator that translates touch gestures (swipe direction and distance) into parameter changes, eliminating the need for complex menu navigation while maintaining precise control over shooting parameters.
2Productivity
If users click buttons to trigger drop-down menus for parameter adjustment, then parameter adjustment is possible, but the time required for adjustment increases due to multiple operation steps
Solution Approach 1:
The sliding control is pre-positioned within the finder frame at locations corresponding to different shooting parameters. This preliminary arrangement means that when users want to adjust a parameter, the control is already there and ready for interaction, eliminating the time needed to navigate to menu screens or search for adjustment options. The controls are prepared in advance within the main interface.
Solution Approach 2:
The patent allows users to skip the intermediate menu navigation steps entirely. By placing the sliding control directly in the finder frame, users can rush through the adjustment process with a single gesture, bypassing the time-consuming sequence of opening menus, selecting parameters, and confirming changes that characterized the previous button-based system.
