Information Processing Apparatus for Content-Linked Vibration and Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for producing vibrations during content playback, such as music, are limited to vibrations dependent on the time series of the audio signal, resulting in a lack of variety and potentially boring experiences for users.
Innovation Solution
An information processing apparatus that decides and executes various processing patterns, including vibrations, illuminations, and animations, based on the playback content, allowing for a wider range of processing types and enhanced user experiences by synchronizing these effects with the content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vibration is produced based on the time series of the acquired audio signal, then the vibration is synchronized with the audio content, but the type of vibration is limited and lacks variety
Solution Approach 1:
The audio signal processing is segmented into multiple frequency bands (e.g., bass, mid-range, high-frequency). Different vibration patterns are assigned to different frequency bands, allowing diverse vibration types to be produced simultaneously while maintaining synchronization with the audio content. This segmentation enables the system to overcome the limitation of producing only single-type vibrations.
Solution Approach 2:
The vibration actuator is designed to perform multiple functions by receiving different control signals for different frequency bands. The same physical actuator can produce various vibration patterns (pulse, continuous, rhythmic) depending on the input signal, making the system versatile without requiring multiple dedicated actuators for each vibration type.
2Adaptability or versatility
If multiple processing patterns are executed in association with content playback, then user experience is enhanced, but system complexity increases
Solution Approach 1:
The system dynamically switches between different processing patterns based on audio characteristics (e.g., genre, tempo, energy level). Rather than executing all patterns simultaneously or requiring complex user configuration, the system adaptively selects and adjusts patterns in real-time, enhancing user experience while keeping the control system manageable through automated decision-making algorithms.
