Interval Walking Route Generation with Curve and Gradient Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interval walking route generation techniques do not adequately consider route features like curves and gradients, potentially leading to unsuitable exercise sections, such as sharp curves or steep slopes, being set for fast walking, which may not provide optimal exercise effects for users.
Innovation Solution
An information processing device that acquires route information including curve and gradient data and adjusts the walking pattern to avoid setting fast walking sections on unsuitable parts of the route, such as sharp curves or steep slopes, by modifying the standard interval walking pattern based on threshold values for curve radius and gradient angles, ensuring a more effective exercise experience.

Engineering Contradiction Analysis
1Productivity
If a repetition cycle of walking at a normal pace and walking at a fast pace is set based only on a predetermined time, then the exercise program can be generated quickly, but sections such as sharp curves or steep slopes that are not suitable for fast walking may be set as fast walking sections
Solution Approach 1:
The system changes the parameters for determining fast walking sections from purely time-based criteria to include spatial parameters such as curve radius and gradient angle. By introducing these new parameters, the system can identify sections that are actually suitable for fast walking, thereby improving the reliability of exercise effects while maintaining efficient route generation.
Solution Approach 2:
The patent replaces the simple temporal mechanism (time-based repetition cycles) with a more complex spatial-aware mechanism that incorporates route geometry (curves and gradients). This substitution allows the system to consider the physical characteristics of the route when determining appropriate walking sections, resolving the contradiction between quick generation and appropriate exercise effects.
2Device complexity
If automatic route generation is performed without considering route features, then the process is simple and fast, but the generated route may include sections unsuitable for fast walking
Solution Approach 1:
The system segments the route into multiple sections based on their characteristics (curves and gradients) and applies different walking speed rules to each segment. By dividing the route into manageable sections, the system can automatically adjust walking patterns to avoid unsuitable sections while maintaining a relatively simple overall process.
Solution Approach 2:
The patent introduces dynamic adjustment of walking speeds based on real-time route characteristics. Instead of using a fixed time-based schedule, the system dynamically modifies the walking pattern according to the current section's curve radius and gradient, making the exercise program adaptable to the route's features while keeping the generation process straightforward.

AI summary
An information processing device includes a route information acquisition unit configured to acquire route information that is information on a route along which a user performs at least two types of moving with different moving speeds, and a section setting unit configured to set, on the route based on the acquired route information, a first section as a section in which the user performs first moving at a first speed and a second section as a section in which the user performs second moving at a second speed lower than the first speed.
