Pedometer Acceleration Data Sharing for Hiking Route Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing body movement detection devices, such as pedometers, lack the ability to share stimulating information based on acceleration data and provide map and route information for hiking, with existing devices being expensive and complex to operate, and unable to utilize measurement information effectively for hiking purposes.
Innovation Solution
A body movement detection device equipped with an acceleration sensor, computation unit, communication unit, and display processing unit that computes and shares exercise intensity, duration, and altitude information with other devices, enabling the display of compatibility and route information for hiking without complex operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If communication is restricted to server-based step count data sharing, then system complexity is reduced, but functionality and user motivation support are insufficient
Solution Approach 1:
The patent combines direct peer-to-peer communication functionality with existing server-based communication in a single system. The pedometer can both transmit data to a server and receive data directly from other pedometers, merging multiple communication modes into one integrated system that enhances functionality without requiring separate devices.
Solution Approach 2:
The communication unit is designed to perform multiple functions: transmitting step count data to servers, receiving acceleration data from other pedometers, receiving exercise intensity data, and displaying compatibility information. This multi-functional communication unit eliminates the need for separate devices for each communication task.
2Loss of information
If expensive and complicated hiking devices are used, then map and route information accuracy is improved, but ease of operation deteriorates
Solution Approach 1:
Instead of using expensive specialized hiking devices, the patent creates a copy of useful information by receiving and displaying map and route data from other pedometers. The acceleration data and step count information from multiple users are compiled to generate virtual map and route information that is free and easily accessible.
Solution Approach 2:
The server acts as an intermediary that collects data from multiple pedometers and processes it into useful map and route information. This intermediary system consolidates data from many simple devices to create the functionality that would otherwise require expensive specialized equipment.
3Loss of information
If past route information is obtained from walking data loggers, then route data is available, but the information cannot be used as map information for hiking
Solution Approach 1:
The patent transforms the parameters of the data by reinterpreting acceleration data and step count information as map and route information. By changing how the data is processed and displayed, past walking routes are converted into usable map information that can guide future hiking activities.

Function Achieved in This Case
Enables mutual data transmission and reception of acceleration-based data between pedometers for sharing stimulating information and provides simple access to route information for hiking, enhancing user motivation and simplifying device operation.

Data Source
AI summary
Information representing an activity intensity computed from a measured step count is transmitted from a first pedometer to a second pedometer as step count-related information. In the second pedometer, walking compatibility is determined based on the difference between the activity intensity in the first pedometer and the activity intensity in the second pedometer, and the determination result is displayed on both pedometers.
