Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eReaders require physical buttons for bookmarking, which can be prone to dust, fluid contamination, and mechanical failure, and do not allow for a seamless user interface.
Innovation Solution
Implementing capacitive touch sensors on the housing of the eReader to detect a pinch and slide gesture for bookmarking actions, eliminating the need for physical buttons and enhancing robustness against environmental contaminants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical buttons are used for bookmarking, then the interface is simple and easy to implement, but the device becomes susceptible to dust, fluid contamination, and mechanical failure
Solution Approach 1:
The patent replaces the mechanical button system with a capacitive touch sensor system. The capacitive sensor detects touch gestures (pinch and slide) through electrical field changes rather than mechanical contact, eliminating physical buttons that are prone to dust and fluid contamination while maintaining user interface functionality.
Solution Approach 2:
The patent creates a virtual copy of the button function through software gesture recognition. Instead of physical buttons, the system uses capacitive touch sensors to detect and interpret pinch and slide gestures, creating a digital representation of the bookmarking action that eliminates mechanical wear and contamination issues.
2Ease of operation
If physical buttons are used for bookmarking, then the implementation is straightforward, but the user interface is not seamless and intuitive
Solution Approach 1:
The patent introduces dynamic gesture-based interaction instead of static button pressing. The capacitive touch sensor system detects and responds to dynamic pinch and slide gestures, creating a more intuitive and seamless user experience that adapts to user actions while maintaining ease of implementation through standard capacitive sensor technology.
3Reliability
If capacitive touch sensors are added to the housing, then the device becomes more robust and button-free, but the device complexity increases
Solution Approach 1:
The patent makes the capacitive touch sensor system multi-functional by using it for both bookmarking gestures and potential display interaction. This universal approach allows a single sensor system to handle multiple user interface functions, reducing the need for separate dedicated components and mitigating the increase in device complexity.

AI summary
A method and system for utilizing a non-screen capacitive touch surface for bookmarking an electronic personal display is disclosed. One example provides a capacitive touch sensing surface on at least two non-planar portions of a housing of the electronic personal display. The capacitive touch sensing surface is monitored for a pinch and slide type contact from at least two non-planar points. In so doing, when the pinch and slide type contact is detected a bookmarking operation on the electronic personal display is performed.
