Long Press Function Button for Execute Privilege Setting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses require cumbersome operations to set execute privileges for functions, as users need to navigate dedicated screens to assign privileges, which is time-consuming and inefficient.
Innovation Solution
An image forming apparatus with a display controller that displays function buttons, a press determination section to differentiate between short and long presses, and an execute privilege setting section that sets privileges based on long press times, allowing users to easily assign execute privileges without a dedicated screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a dedicated screen is used to set execute privileges for each function, then the execute privilege can be set accurately, but the operation becomes time-consuming and troublesome
Solution Approach 1:
The patent merges the function execution button and the execute privilege setting function into a single interface element. By long-pressing the function button on the main screen, users can directly set execute privileges without navigating to a dedicated settings screen, thus combining multiple operations into one unified interaction flow
Solution Approach 2:
Instead of requiring users to proactively search for and access a dedicated privilege setting screen, the patent inverts the interaction by allowing privilege setting to be triggered passively through a long-press action on the function button itself, making the setting function come to the user rather than the user going to the setting function
2Reliability
If a dedicated screen is used to set execute privileges for each function, then the privilege can be set correctly, but the operation becomes complex and troublesome
Solution Approach 1:
The patent combines the function selection and privilege setting operations into a single button interaction. The function button serves dual purposes: normal pressing executes the function, while long-pressing opens the privilege setting interface, eliminating the need to navigate through multiple screens and menus
Solution Approach 2:
The function button itself provides the privilege setting capability through long-pressing, making the system self-configuring in a sense. Users can directly interact with the function button to set privileges without needing to access separate configuration menus or screens, simplifying the operational flow

AI summary
An image forming apparatus includes: a display controller that displays an operation screen including a function button for executing a function on a display section; a press determination section that determines whether the function button is short pressed or long pressed; when the press determination section determines that the function button is short pressed, a function execution section that executes the function; and when the press determination section determines that the function button is long pressed, an execute privilege setting section that sets an execute privilege of the function from a plurality of types of execute privileges in accordance with a long press time of the function button.
