Pressure-Sensitive Touch Screen for Handheld eBook Reader
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eBook readers lack intuitive and efficient mechanisms for user interaction, particularly in navigating and bookmarking digital content, and organizing large collections of electronic books based on size or reading time.
Innovation Solution
A handheld eBook reader device equipped with a touch-screen display that utilizes pressure-sensitive technology to enable three-dimensional input for page turning, bookmarking, and filtering, along with microphones for additional input methods, and a text-to-speech module for converting text to speech.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch-screen display is used for user interaction, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The touch-screen display serves multiple functions: displaying content, detecting user input, and enabling three-dimensional interaction. By combining display and input functions into a single component, the patent reduces the need for separate buttons, knobs, and other input devices, thereby simplifying the overall device while improving ease of operation.
Solution Approach 2:
The patent introduces three-dimensional input capability to the traditional two-dimensional touch screen by detecting pressure magnitude. This adds a vertical dimension to user interaction, allowing users to control page turning, bookmarking, and other functions through pressure-sensitive gestures, thereby enhancing usability without adding separate control mechanisms.
2Ease of operation
If three-dimensional input is enabled through pressure-sensitive technology, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent utilizes changes in pressure parameters to differentiate between various user actions. By detecting variations in pressure magnitude, the system can distinguish between light touches for navigation and firmer presses for bookmarking, enabling intuitive three-dimensional interaction through software-based interpretation of pressure parameter changes rather than requiring complex mechanical precision.
3Adaptability or versatility
If microphones are added for input methods, then adaptability is improved, but device complexity increases
Solution Approach 1:
The microphone serves as an intermediary input mechanism that captures user commands through voice or acoustic signals. This allows users to interact with the eBook reader without direct physical contact with the display, adding accessibility and versatility. The acoustic field acts as a mediator between the user and the system, enabling hands-free operation while maintaining integration within the existing device architecture.
4Adaptability or versatility
If text-to-speech module is implemented, then adaptability is improved, but use of energy increases
Solution Approach 1:
The text-to-speech module enables the device to serve itself by automatically converting displayed text into audible speech. This functionality allows the system to provide accessibility features and hands-free operation without requiring additional user input or external assistance, thereby enhancing adaptability while managing energy consumption through automated service rather than manual operation.

AI summary
A user interface for a touch-screen display of a dedicated handheld electronic book reader device is described. The user interface detects human gestures manifest as pressure being applied by a finger or stylus to regions on the touch-screen display. In one implementation, the touch-screen user interface enables a user to turn one or more pages in response to applying a force or pressure to the touch-screen display. In another implementation, the touch-screen user interface is configured to bookmark a page temporarily by applying a pressure to the display, then allowing a user to turn pages to a new page, but reverting back to a previously-displayed page when the pressure is removed. In another implementation, the touch-screen user interface identifies and filters electronic books based on book size and/or a time available to read a book. In another implementation, the touch-screen user interface converts text to speech in response to a user touching the touch-screen display.
