Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing moving body technologies fail to consider user easiness in navigating surrounding situations, leading to potential collisions with obstacles or dangerous materials, as they rely on user judgment or autonomous systems that may not effectively avoid hazards.
Innovation Solution
A moving body apparatus equipped with user detection, surrounding situation detection, prediction, and direction determination devices to show the user an appropriate moving direction based on predicted future situations and movement easiness evaluation, ensuring safe and easy navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the moving body autonomously avoids obstacles, then obstacle avoidance capability is improved, but the user cannot directly control the avoidance behavior
Solution Approach 1:
The moving body acts as an intermediary that detects obstacles and communicates this information to the user through display devices. The system provides obstacle information to the user while maintaining autonomous detection capabilities, allowing the user to make informed decisions about avoidance actions.
Solution Approach 2:
The system implements feedback by displaying detected obstacle information back to the user. This allows the user to see what the moving body has detected and understand the situation, enabling the user to provide appropriate control inputs for obstacle avoidance based on the provided information.
2Ease of operation
If the moving body provides autonomous navigation guidance, then user navigation ease is improved, but the system complexity increases
Solution Approach 1:
The system is segmented into distinct functional modules: detection devices for sensing the environment, prediction devices for forecasting future states, determination devices for deciding navigation directions, and display devices for presenting information to the user. This modular segmentation manages complexity by organizing functions into separate, manageable components.
Solution Approach 2:
The prediction device performs preliminary actions by forecasting future environmental states and potential obstacles before the user needs to make navigation decisions. This advance prediction allows the system to prepare navigation guidance in advance, reducing the cognitive load on the user during actual navigation.
3Reliability
If the moving body predicts future surrounding situations, then collision risk is reduced, but the prediction accuracy requirements increase
Solution Approach 1:
The prediction device performs partial prediction by focusing on predicting only the relevant future states that affect navigation safety, rather than attempting to predict all possible future conditions. This selective prediction approach reduces the overall accuracy requirements while still achieving sufficient collision risk reduction.

AI summary
According to the present invention, on the basis of the detected surrounding situation the movement of object bodies in the surrounding area is predicted as a future situation in the surrounding area. Candidates of direction from which a moving direction to be shown to the user is determined are extracted on the basis of the predicted future situation in the surrounding area. The extracted candidates are evaluated for movement easiness of the user in the surrounding area on the basis of the predicted future situation in the surrounding area and the detected situation of the user. Then, the moving direction to be shown to the user is determined on the basis of the evaluation and the extracted candidates. A direction corresponding to the determined moving direction is shown to the user in front of the user.
