Predated Playback Recording for Missed Ambient Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques fail to effectively recheck information such as sound and image that are one-sidedly provided in unexpected situations, like train announcements or advertisements, as they are not designed to handle such transient and unpredictable data.
Innovation Solution
An information processing apparatus and method that includes a recording section to continuously acquire data via sensors and a controlling section to manage playback, allowing users to replay recorded data from a timing predicated on user input, enabling rechecking of missed sound or image information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is continuously recorded via sensor, then ability to recheck information is improved, but device complexity increases
Solution Approach 1:
The smartphone serves multiple functions: it acts as both a regular communication device and a recording/playback device for ambient sound. The existing smartphone components (microphone, storage, processor, speaker) are utilized for recording and playing back ambient sound, eliminating the need for dedicated recording hardware and reducing overall device complexity.
Solution Approach 2:
The system uses the smartphone's own built-in components to record and playback sound. The microphone records ambient sound, the processor manages the recording logic and predated timing calculation, and the speaker plays back the recorded sound. This self-service approach avoids needing external or additional specialized equipment.
2Ease of operation
If playback starts from timing predicated on user input, then ease of operation is improved, but measurement precision deteriorates
Solution Approach 1:
The system continuously records ambient sound in advance (predated timing) before the user realizes they missed something. When the user provides input after missing sound information, the system calculates the appropriate predated timing and plays back only that relevant segment. This preliminary continuous recording ensures that even though timing precision cannot be perfectly determined retroactively, the user can still retrieve the missed information effectively.
Data Source
AI summary
There is provided an information processing apparatus including a recording section recording data continuously acquired via a sensor; and a controlling section controlling a playback of record data recorded by the recording section, wherein, in response to a user input, the controlling section performs control such that the record data is played from a timing predated with reference to a timing of the user input.
