Capacitive Gesture Recognition Book for Immersive Audio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional audio storybooks require users to physically locate and press buttons to activate audio playback, which can be distracting and detract from the immersive experience, as the presence of buttons is obvious and disrupts the surprise of audio activation.
Innovation Solution
A capacitive gesture recognition book that uses capacitive sensors embedded within the book base to detect user interactions, such as finger movements or gestures, to activate corresponding audio recordings associated with page features, allowing for seamless and hidden audio playback without visible buttons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional buttons are used for audio activation, then the audio playback function is reliable and easy to operate, but the visible buttons disrupt the immersive experience and reduce surprise
Solution Approach 1:
The patent extracts the audio activation function from visible buttons and relocates it to invisible capacitive sensors embedded within the book base. This removes the harmful visual element while preserving the functional capability, allowing users to interact without seeing the control mechanism.
Solution Approach 2:
The patent replaces the mechanical button-pressing system with a capacitive sensing system that detects changes in electrical capacitance through touch or proximity. This substitution eliminates the need for visible mechanical buttons while maintaining ease of operation through intuitive finger interactions.
2Object-affected harmful factors
If capacitive sensors are embedded within the book base, then the visual disruption is eliminated and immersion is improved, but the device complexity increases
Solution Approach 1:
The patent makes the book base serve multiple functions: it provides structural support, houses the capacitive sensors for interaction detection, and manages the audio playback system. This multi-functionality reduces overall system complexity by consolidating components into a single integrated structure.
Solution Approach 2:
The capacitive sensors are nested within the book base structure, with the sensing surface positioned beneath the page surface. This nested arrangement integrates the electronic components into the existing book geometry without adding external complexity or visible elements.
3Shape
If capacitive sensors are positioned beneath the page surface, then the book maintains simplicity and paper-like appearance, but the detection precision must be high to accurately distinguish gestures from normal handling
Solution Approach 1:
The patent employs dynamic gesture recognition that analyzes the temporal sequence and spatial pattern of capacitive sensor activations. By detecting the dynamic characteristics of user interactions (such as the order and duration of sensor activations), the system achieves high measurement precision while maintaining the simple book appearance.

AI summary
A capacitive gesture recognition book includes a plurality of capacitive sensors concealed in a base cover of the book. The capacitive sensors detect changes in capacitance brought on by a finger of a user coming in proximity with the capacitive sensor. A processor located in the base cover includes a plurality of capacitive activation sequences and a plurality of corresponding responses stored therein. Upon detection of a stored capacitive activation sequence, the processor initiates activation of the corresponding response which may be playback of an audio file. The book includes a plurality of pages that contain graphics and/or words for a storyline. The graphics can include images intended to direct a user of a desired motion to be made that corresponds with activation of sensors in a manner stored as a capacitive activation sequence.
