Dual-Screen Mobile Device Rear Touch Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ebook reading on mobile devices involves complex operations for users to navigate and jump to specific chapters, reducing transaction processing efficiency and user experience due to the need for multiple steps and inaccurate chapter location.
Innovation Solution
A mobile device with a capacitive touchscreen on the front and an electronic ink screen on the rear, where touch operations on the rear panel detect gestures to display a second GUI for fast page flipping and navigating the ebook's catalogue, simplifying operations and improving efficiency by using the rear screen for content display and the front for controls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user performs page flip and chapter jumping operations on a single front touch display screen, then the device structure remains simple, but the operation steps become complex and transaction processing efficiency decreases
Solution Approach 1:
The device is divided into two functional screens: a front touch display screen for control operations and a rear touch display screen for content display. This segmentation allows the front screen to handle all interaction operations while the rear screen displays content, thereby simplifying user operations without significantly increasing overall device complexity.
Solution Approach 2:
The front touch display screen acts as an intermediary between the user and the ebook content. All user interactions (page flipping, chapter jumping, catalog navigation) are performed on the front screen, which then translates these operations into corresponding actions on the rear screen displaying the ebook content.
2Ease of operation
If the front touch display screen displays both controls and ebook content, then the device structure remains simple, but the user experience deteriorates due to space constraints
Solution Approach 1:
The display function is segmented between two screens: the front touch display screen is dedicated to control operations (catalog, chapter selection, page flipping) while the rear touch display screen is dedicated to displaying ebook content. This provides ample space for both controls and content without compromising user experience.
Solution Approach 2:
The solution moves from a two-dimensional layout on a single screen to utilizing the third dimension (front and rear faces of the device) for display. This allows controls on the front face and content on the rear face, effectively increasing the available display area without compromising portability.
3Productivity
If the front touch display screen is used for both controls and content display, then the device structure remains simple, but transaction processing efficiency decreases due to complex operations
Solution Approach 1:
By segmenting the functional roles of the two screens, the front screen can be optimized for rapid control operations (one-touch page flipping, quick chapter jumping) while the rear screen handles content rendering. This division enables faster transaction processing as control operations are simplified and executed more efficiently.
Solution Approach 2:
The system automatically translates front screen control operations into corresponding rear screen content updates without requiring additional user steps. For example, a page flip gesture on the front screen automatically triggers the corresponding page flip on the rear screen, streamlining the transaction process.
