Solution Overview

Problem

Existing wearable computing devices face inaccuracies in sleep data analysis due to varying sleep patterns among users, as standard sleep analysis models are not tailored to specific sleeper types, leading to inaccurate measurements for users who exhibit high movement during sleep.

Innovation Solution

A wearable computing device that determines a user's sleeper type based on motion sensor data, such as average time between movements, and selects a corresponding sleep analysis model to accurately analyze sleep characteristics, including sleep states and quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a standard sleep analysis model is used for all users, then the device complexity is reduced and ease of operation is improved, but the measurement precision of sleep data deteriorates for users with varying sleep patterns

Engineering Contradiction:
Improvesleep data accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the user population into different sleeper types (e.g., high-movement sleepers, low-movement sleepers) based on motion characteristics. Multiple sleep analysis models are created, each optimized for specific sleeper types. The system divides the analysis task by first classifying the user's sleeper type and then selecting the appropriate model, thereby improving measurement precision without requiring a single overly complex model to handle all cases.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent changes the parameter of model selection based on user characteristics. Instead of using a fixed model for all users, the system adjusts which model is applied by changing the model selection parameter according to the detected sleeper type. This allows the system to adapt to different sleep patterns while maintaining manageable complexity through parameter-based model selection rather than implementing a single complex adaptive model.

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If multiple sleep analysis models are maintained for different sleeper types, then the measurement precision of sleep data is improved, but the device complexity and difficulty of operation increase

Engineering Contradiction:
Improvesleep data accuracyVSAvoiduser interaction complexity
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The system performs self-service by automatically classifying the user's sleeper type and selecting the appropriate analysis model without requiring user input or manual configuration. The wearable device autonomously handles the complexity of multiple models by implementing automatic sleeper type detection based on motion sensor data, thereby maintaining ease of operation while improving measurement precision through customized analysis.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary classification of the user's sleeper type before selecting and applying the appropriate sleep analysis model. This preliminary action of identifying the sleeper type based on motion characteristics allows the system to prepare and select the correct model in advance, ensuring accurate analysis without requiring the user to understand or manage the multiple available models.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If a single sleep analysis model is used for all users, then the system complexity is reduced, but the reliability of sleep data deteriorates for specific sleeper types

Engineering Contradiction:
Improvesleep data reliabilityVSAvoidmodel selection system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a dynamic model selection system that adapts to each user's sleep characteristics. Instead of using a static single model for all users, the system dynamically determines the appropriate model based on real-time or historical motion data analysis. This dynamic approach improves reliability by matching the analysis model to the user's actual sleep patterns while managing complexity through automated classification algorithms.

Inventive Principle:
Principle #15Dynamics

AI summary

The present disclosure is directed towards systems and methods for improving analysis of sleep data by classifying users based on sleeper type. In particular, a wearable computing system can obtain a first set of motion sensor data from the motion sensor for a user during a first period. The wearable computing system can determine a sleeper type from a plurality of sleeper types for the user based on the first set of motion sensor data received from the motion sensor. The wearable computing system can select a sleep analysis model from a plurality of sleep analysis models based on the sleeper type determined for the user. The wearable computing system can use the selected sleep analysis model to analyze a second set of motion sensor data from a second period to determine one or more sleep characteristics for the user during the second period.
