Dynamic Route Generation for Personal Navigation Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional personal navigation devices for outdoor activities like hiking, jogging, or cycling lack variety in route options and do not provide personalized routes based on user preferences or training programs, leading to user fatigue and reduced motivation.
Innovation Solution
A method for creating multiple suggested exercise routes on a personal navigation device based on user input such as current location, route length, terrain type, and difficulty level, allowing users to select from automatically generated routes or manually create their own, with features like the 'Surprise me' function for varied experiences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional personal navigation devices provide a single fixed route, then route generation is simple and quick, but the user experiences monotony and reduced motivation over time
Solution Approach 1:
The system dynamically generates multiple alternative routes by varying route parameters such as terrain type, difficulty level, and length. Instead of providing a single static route, the navigation device creates multiple dynamic route options that adapt to user preferences and exercise goals, thereby increasing route variety without requiring complex manual planning from the user.
Solution Approach 2:
The system changes multiple route parameters simultaneously (terrain type, difficulty, length, waypoints) to generate diverse route variations. By systematically varying these parameters, the device produces multiple distinct route options that cater to different user preferences and fitness levels, resolving the contradiction between route variety and system complexity.
2Loss of time
If the device automatically generates exercise routes, then route planning time is reduced, but the user has less control over personalized route preferences
Solution Approach 1:
The system performs preliminary actions by pre-defining multiple route parameters (terrain type, difficulty level, length, waypoints) based on user preferences before route generation. This allows the device to automatically generate personalized routes that respect user preferences without requiring the user to manually plan each route, thus saving time while maintaining user control over key exercise parameters.
Solution Approach 2:
The system incorporates feedback mechanisms where user selections of preferred terrain types, difficulty levels, and route lengths are used to generate customized route options. The device then presents these generated routes to the user for selection, creating a feedback loop that ensures automated route generation aligns with user preferences and maintains ease of operation.
3Adaptability or versatility
If multiple suggested routes are generated, then user engagement and exercise variety increase, but computational processing requirements increase
Solution Approach 1:
The system segments the route generation process by creating multiple independent route options based on common parameter sets. Instead of generating one complex optimized route, the device divides the task into multiple simpler route generations with varying parameters, allowing for parallel processing and reduced computational burden per route while still providing diverse options to the user.

AI summary
A method of creating an exercise route for a user of a personal navigation device (10) includes receiving a selection of a length of an exercise route to be generated, and generating a first plurality of suggested exercise routes, each suggested exercise route of the first plurality of suggested exercise routes being generated according to a current position of the personal navigation device (10), one or more waypoints to be visited along the suggested exercise route, and the selected length of the exercise route, wherein each of the first plurality of suggested exercise routes has a starting point and ending point substantially equal to one another and equal to the current position of the personal navigation device (10). The method further includes receiving, from the user, selection of a selected suggested exercise route from the first plurality of suggested exercise routes, and displaying routing instructions for the selected suggested exercise route.
