Gesture-Based Navigation in 3D Route Environments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in controlling viewing positions within three-dimensional environments comprising routes, making it challenging to navigate and change perspectives effectively.
Innovation Solution
A method and apparatus that utilize gesture user inputs to detect changes in viewing positions and select corresponding perspective views, allowing users to navigate through three-dimensional environments by changing their viewing position and orientation, with the ability to select new positions from predetermined waypoints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional viewing position control methods are used, then the system can display perspective views of the three-dimensional environment, but users find it difficult to control the viewing position
Solution Approach 1:
The patent replaces complex mechanical or manual control mechanisms with gesture-based input detection. The system captures hand gestures in a defined gesture space and automatically determines viewing position changes, eliminating the need for complex control interfaces while maintaining intuitive user interaction.
Solution Approach 2:
The patent introduces a gesture space as an intermediary between the user and the three-dimensional environment. Hand gestures performed in this virtual gesture space serve as a mediator to control viewing positions, translating simple user motions into meaningful navigation commands without direct manipulation of the environment itself.
2Adaptability or versatility
If multiple perspective views are provided for navigation, then users can change viewing positions, but the system complexity increases
Solution Approach 1:
The patent segments the gesture space into distinct regions that correspond to different navigation directions and viewing position changes. By dividing the gesture input space into meaningful segments (e.g., left, right, forward, backward gestures), the system can provide multiple viewing options while managing complexity through structured classification of gestures.
Solution Approach 2:
The patent implements dynamic viewing position changes based on real-time gesture detection. The system continuously monitors gestures and updates the viewing position accordingly, allowing flexible and adaptive navigation. This dynamic response enables multiple viewing options to be accessed through simple, real-time user actions rather than requiring complex pre-configured views.

AI summary
A method comprising: presenting a three-dimensional environment, comprising routes, to a user by using a selected one of a plurality of perspective views of the environment that corresponds to a current position on a current route; detecting a gesture user input comprising a characteristic that changes in time, and changing the current position on the current route to a new position on a route in response to the gesture user input wherein a first characteristic of the gesture user input determines a direction along the current route of the new position relative to the current position and a second characteristic of the gesture user input determines the new position; and presenting the three-dimensional environment, comprising routes, to the user by using a newly selected one of the plurality of perspective views of the environment that corresponds to the new position.
