Operation Device Visual Feedback for Optical Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing object distance display apparatuses lack the ability to visually and effectively display the relationship between the operation amount of an operation member and the corresponding command or controlled values, leading to reduced operability.
Innovation Solution
An operation device that includes an operation member, a detector to measure the operation amount, and a controller to generate command values, which displays a first region corresponding to the command or controlled values and a second region corresponding to the operation amount, with marks indicating these values, allowing users to visually understand the relationship between operation and command values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an object distance display apparatus merely displays the object distance based on focus instruction position, then the device complexity is reduced, but the operability of the operation member deteriorates due to lack of visual feedback on the relationship between operation amount and command value
Solution Approach 1:
The patent introduces a visual display dimension to represent the relationship between operation amount and command value. By displaying multiple regions (first region for command value range, second region for operation amount range) with corresponding marks, the system transforms the invisible relationship into a visible spatial representation, improving operability without significantly increasing device complexity
Solution Approach 2:
The display acts as an intermediary between the operation member and the control system. It provides visual feedback that mediates the user's understanding of how operation amount translates to command value, enabling better operational control without requiring direct modification of the control mechanism
2Loss of information
If no visual display of the relationship between operation amount and command value is provided, then the device complexity is low, but the loss of information occurs as users cannot sensuously understand the operational parameters
Solution Approach 1:
The patent uses visual markers and regional distinctions in the display to represent different parameter ranges. By employing visual cues such as marks indicating specific values and regions representing different scales, the system preserves information about operational parameters in an easily perceivable format
Solution Approach 2:
The relationship between operation amount and command value is transformed from an abstract numerical relationship into a visual spatial representation. The display shows multiple regions with marks that visually encode parameter information, preventing information loss while maintaining relatively simple device architecture

AI summary
An operation device for performing control of a movable optical element to change an optical characteristic of an optical apparatus includes an operation member, a detector configured to detect an operation amount of the operation member, and a controller configured to generate a command for the control based on the operation amount. The controller is configured to cause a display to display a first region, a first mark, a second region, and a second mark. The first region corresponds to a range of values of one of the command and a controlled value for the control. The first mark indicates one of the command and the controlled value associated with the first region. The second region corresponds to a range of values of the operation amount. The second mark indicates the operation amount associated with the second region.
