Dynamic Icon Mapping on E-Reader Physical Controls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current e-book reader devices face confusion due to fixed physical controls, where the functionality of keys is often misinterpreted as it cannot be easily changed to match user preferences for frequently executed tasks.
Innovation Solution
The electronic reader device employs a physical control module with layers of detection pads and light-based touch sensors, allowing icons to be dynamically associated with functions through drag operations, enabling users to customize key functionalities without printed icons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If printed icons are fixed on functional keys, then key functions are clearly indicated, but user customization capability is lost causing confusion
Solution Approach 1:
The patent implements dynamic icon display on physical keys through a controller that can change the displayed icon based on the currently active application or function. The physical control module includes a display element that dynamically updates to show relevant icons, allowing the same physical key to serve multiple functions contextually. This resolves the contradiction by making the key function adaptable (improving versatility) while maintaining clear visual indication (preventing information loss) through real-time dynamic updates.
Solution Approach 2:
The system changes the visual parameter (displayed icon) of the physical control module based on the operational context. The controller monitors the active application and changes the icon displayed on the physical key accordingly, allowing the key to adapt its function without physical modification. This enables customization capability while maintaining clear function indication through parameter (icon) changes.
2Ease of operation
If physical controls are designed for common tasks, then execution convenience is improved, but flexibility for user preferences is reduced
Solution Approach 1:
The physical control module is designed to perform multiple functions by dynamically displaying different icons based on the active application. The same physical key can serve as a functional key for one application and a different functional key for another application, making the control system universal and adaptable to user preferences while maintaining ease of operation for common tasks.
Solution Approach 2:
The system provides visual feedback through the displayed icon on the physical key, indicating what function the key will perform in the current context. This feedback mechanism allows users to understand the key's current function before pressing it, enabling both convenient execution of common tasks and adaptation to user preferences through contextual awareness.
3Adaptability or versatility
If functional keys have fixed meanings, then manufacturing simplicity is maintained, but device complexity increases to support customization
Solution Approach 1:
The patent merges the physical control module with a display element and controller to create an integrated system. The physical key, display, and control logic are combined into a single module, allowing function reassignment capability without adding separate customization hardware. This merging approach enables adaptability while managing device complexity through integration rather than addition of separate components.

AI summary
An electronic reader device with a physical control disposed on a surface of the device housing. The physical control is operable to initiate a first function. A display disposed on the surface of the housing is operable to show a virtual control that initiates a second function. A sensor detects a drag operation moving the virtual control to a position on a border of the display adjacent to the physical control. A processor associates the second function with the physical control in response to the drag operation and performs the second function upon activation of the physical control.
