Stride-Based Route Guidance for Pedestrian Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation systems for pedestrians are not intuitive as they provide distance information in standard units, which does not account for individual stride lengths, making it difficult for pedestrians to perceive remaining distances effectively.
Innovation Solution
A stride-based route guiding apparatus and method that includes sensors to detect a pedestrian's stride, a unit to estimate pace, and a system to convert distances into the number of steps, providing route guidance based on the pedestrian's stride frequency and pace, allowing for more personalized and intuitive navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If standard distance units (meters/miles) are used for route guidance, then the navigation system can provide universal distance information, but pedestrians cannot intuitively perceive the remaining distance due to varying stride lengths
Solution Approach 1:
The system customizes the distance representation to match each pedestrian's local characteristics (stride length). By detecting individual stride patterns and converting standard distance measurements into personalized step counts, the system makes the navigation information locally adapted to each user's physical attributes, enabling intuitive perception of remaining distance.
Solution Approach 2:
The system transforms the distance parameter from standard units (meters/miles) to a personalized unit (number of steps) based on detected stride characteristics. This parameter change allows the same physical distance to be represented differently for each pedestrian according to their walking pattern, resolving the contradiction between universal measurement and individual adaptability.
2Adaptability or versatility
If stride detection sensors and processing units are added to personalize route guidance, then individualized step-based navigation is achieved, but device complexity increases
Solution Approach 1:
The system uses a smartphone's existing multi-functional sensors (accelerometer, gyroscope, GPS) that serve both general motion tracking and specific stride detection purposes. By leveraging the universal capabilities already present in mobile devices, the system achieves personalized stride-based navigation without adding dedicated specialized hardware, thus minimizing the increase in device complexity.
Solution Approach 2:
The system utilizes the pedestrian's own natural walking motion as the measurement source, eliminating the need for external calibration equipment or specialized sensors. The smartphone's existing sensors automatically capture stride information during normal use, and the system processes this data through algorithmic analysis rather than requiring additional hardware processing units.

AI summary
Disclosed is a stride-based route guiding apparatus and method capable of providing a pedestrian with a stride-based route. The method includes detecting a stride of the pedestrian on the basis of a pace inherent to the pedestrian of interest and converting a remaining distance from a current position to a major position or destination into the number of steps so as to provide the pedestrian with the number of steps to the major position or destination when a route is shown, using a navigation system built in a mobile terminal. Since the route is shown on the basis of the number of steps inherent to the pedestrian, the pedestrian can receive the routing more familiar to herself or himself, and easily and intuitively perceive the route from the current position to the major position or destination.
