Cyclic Motion Gesture Recognition for E-Reader False Trigger Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch screen devices for e-reading face challenges in efficiently managing gestures for navigation and returning to reading mode without causing false-page-turn triggers, especially when users switch hands or put down the device.
Innovation Solution
Integration of motion sensors, such as accelerometers and gyroscopes, to detect specific motion gestures like a single shake up and down, allowing users to seamlessly transition back to reading mode from diversion windows without the need for traditional buttons, and enabling intuitive one-handed operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional touch-based gestures are used for navigation, then the device can respond to user input, but false-page-turn triggers occur when users switch hands or put down the device
Solution Approach 1:
The patent combines multiple sensing modalities (accelerometer, gyroscope, and touch sensor) into an integrated gesture recognition system. By merging data from these different sensors, the system can distinguish between intentional navigation gestures and accidental movements, thereby improving reliability while maintaining ease of operation.
Solution Approach 2:
The motion sensors act as an intermediary layer between the user's physical movements and the device's response. Instead of directly interpreting touch screen gestures, the system uses accelerometer and gyroscope data as intermediaries to verify the intent behind navigation commands, filtering out false triggers caused by hand switching or device placement.
2Reliability
If motion sensors are integrated to detect specific motion gestures, then false-page-turn triggers are filtered out, but device complexity increases
Solution Approach 1:
The motion sensor system is designed to serve multiple functions: detecting page-turn gestures, identifying when the device is being put down, recognizing hand-switching patterns, and enabling one-handed operation modes. By making the sensor system universal and multi-functional, the patent reduces overall system complexity rather than increasing it, as a single integrated solution handles multiple gesture recognition tasks.
3Ease of operation
If cyclic motion gestures are implemented for navigation, then one-handed operation is enabled, but the system must distinguish between intentional gestures and accidental movements
Solution Approach 1:
The patent implements cyclic motion detection by analyzing periodic patterns in accelerometer and gyroscope data. The system looks for repeating motion cycles that characterize intentional navigation gestures, distinguishing them from random or accidental movements. This periodic action analysis enables reliable one-handed operation by recognizing deliberate cyclic gestures while ignoring sporadic movements.

AI summary
A method and system for cyclic motion gesturing is provided. The method includes receiving at a motion sensor coupled with a processor a first motion associated with an e-reader, receiving a second motion associated with an e-reader at the motion sensor, the second motion being a counter motion of the first motion, wherein the first and second motions are associated with moving the e-reader form a first point in space to a second point in space and then back to the first point in space within a predetermined period of time, determining the first and second motions indicate a multi-motion command gesture corresponding to a first function performable on the e-Reader and automatically performing the first function on the e-reader in response to the multi-motion command gesture.
