Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices require users to manually input exercise start and end commands, leading to user frustration and discrepancies between measured and perceived exercise amounts.
Innovation Solution
An electronic device with a sensor and processor that automatically determines the most prevalent activity state over a time period, omitting short bursts of secondary activities to provide a more intuitive and accurate representation of user activity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the device records all detected activity states including short bursts of secondary activities, then the measurement precision is improved, but the ease of operation deteriorates due to user frustration from discrepancies between measured and perceived exercise amounts
Solution Approach 1:
The patent extracts and removes short-duration secondary activities from the recorded activity data, keeping only the predominant activity states. This filtering approach resolves the contradiction by eliminating noisy data points that cause user frustration while preserving the core exercise information that users can perceive and understand.
Solution Approach 2:
The patent segments the continuous activity data into discrete time intervals and identifies the predominant activity in each segment. By dividing the activity record into manageable segments and selecting representative activities, the system achieves both measurement precision and user acceptance.
2Loss of information
If the device provides detailed activity information including all detected activities, then the loss of information is reduced, but the device complexity increases making it harder to understand
Solution Approach 1:
The patent extracts only the predominant activity states from the complete activity data, removing次要 activities that would complicate the information presentation. This selective extraction maintains the essential information while simplifying the display for user understanding.
Solution Approach 2:
Instead of presenting all detected activities and filtering what users should pay attention to, the patent inverts the approach by pre-filtering to show only the most significant activities. This inversion simplifies the information architecture while preserving the most valuable data.
3Ease of operation
If the device uses manual input commands for exercise start and end, then the ease of operation is improved for simple cases, but the productivity deteriorates due to user frustration and time consumption
Solution Approach 1:
The patent enables the device to automatically detect and record exercise activities without requiring manual user input. The system serves itself by using sensors to identify activity states autonomously, eliminating the need for users to manually start and stop tracking while improving overall tracking efficiency and accuracy.
Solution Approach 2:
The patent replaces the mechanical manual input system with an automated sensor-based detection system. By substituting physical button presses or voice commands with automatic motion sensing, the system maintains operational simplicity while dramatically improving productivity and reducing user frustration.
Data Source
AI summary
An electronic device may measure a user's exercise or other activity and output intuitive information regarding the activity. The electronic device may include a sensor that senses a movement of the electronic device. A processor may determine types of activity states of specified unit times, and determine a specific activity state as a representative activity state of a specified time range based on distribution of the activity states of the specified unit times. The processor may output information corresponding to a determined representative activity state. Short bursts of secondary activity which occur during the specified time range may be omitted in the output information.
