Wearable Device Logging Emotional States via Intermediary Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable devices cannot log and record a person's emotional state, preventing users from objectively reflecting on their emotional experiences.
Innovation Solution
A wearable device with a detection unit, signal communication unit, and stimulus application unit that logs emotional states and wirelessly transmits this information to an information processing apparatus, which prompts users to input their experiences and records the data for later reflection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a wearable device provides rhythmic tactile stimulus to change heart rate, then physiological parameters can be controlled, but the device cannot log and record emotional states for later reflection
Solution Approach 1:
The patent introduces an information processing apparatus as an intermediary between the wearable device and the user's reflection process. The wearable device detects emotional states and transmits this data to the information processing apparatus, which then logs, stores, and presents the data for later review. This intermediary system resolves the contradiction by handling the logging and storage functions externally, allowing the wearable device to remain relatively simple while still capturing and preserving emotional state information for future reflection.
2Reliability
If the wearable device logs detection results locally, then data is available for immediate processing, but the device becomes more complex and requires additional storage components
Solution Approach 1:
The patent extracts the logging and storage functions from the wearable device itself and places them in a separate information processing apparatus. The wearable device focuses on detection and wireless transmission of data, while the information processing apparatus handles data logging, storage, and presentation. This separation of functions resolves the contradiction by maintaining data availability through dedicated storage infrastructure while keeping the wearable device structure simple and focused on its core detection and stimulation functions.
3Speed
If the device applies stimulus immediately upon detecting specific state, then real-time emotional control is achieved, but there is no opportunity for the user to objectively reflect on their emotional experiences
Solution Approach 1:
The patent implements preliminary action by logging and storing emotional state data before presenting it for user reflection. The system detects emotional states, immediately transmits and logs this data, then later presents the logged information to the user for objective review. This preliminary logging action ensures that emotional state information is preserved and made available for future reflection, resolving the contradiction between immediate stimulus application and providing reflection opportunities.
4Loss of information
If the information processing apparatus prompts frequent user input, then detailed emotional data is collected, but user convenience decreases due to repeated interactions
Solution Approach 1:
The patent implements periodic action by having the information processing apparatus prompt users for input at scheduled intervals rather than continuously. The system logs emotional state data automatically and then periodically presents this logged information to users for confirmation or additional input. This periodic interaction approach resolves the contradiction by collecting detailed emotional data through structured, spaced-out user interactions rather than requiring constant user engagement, thereby maintaining data completeness while improving user convenience.

AI summary
A detection unit (88) detects a specific state of a wearer. A signal communication unit (92) wirelessly transmits, to an information processing apparatus, log information indicating a detection result obtained by the detection unit (88) detecting the specific state and a date and time when the specific state is detected. A stimulus application unit (94) applies a stimulus to the wearer when the specific state is detected by the detection unit (88).
