Spatial Awareness Feedback for Handling Bulky Objects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Human sensory limitations hinder safe handling and interaction with complex or bulky objects, particularly in dynamic environments, leading to reduced focus on the task and increased risk of collisions or interference.
Innovation Solution
A method and system that determine an area of interest encompassing multiple entities, evaluating deviations from a target state, and communicate these deviations to the user using coherent stimuli to enhance awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a person handles bulky or complexly shaped objects, then the ability to perform complex tasks is improved, but the person's perceptual and cognitive resources are overwhelmed leading to reduced safety awareness
Solution Approach 1:
The system segments the environment into multiple entities (objects, obstacles, persons) and processes each separately through sensor arrays and tracking algorithms, allowing the person to interact with complex objects without being overwhelmed by the entire scene's complexity
Solution Approach 2:
The system introduces an intermediary computational layer between the person and the environment, where sensors, processors, and algorithms mediate the interaction by automatically detecting, tracking, and evaluating spatial relationships, freeing the person's cognitive resources while maintaining safety awareness
2Device complexity
If traditional 2D screen interfaces are used for teleoperation, then device complexity is reduced, but depth information and spatial awareness are insufficient leading to unsafe operations
Solution Approach 1:
The system transitions from 2D screen representation to 3D spatial awareness by deploying sensor arrays that capture depth information, volumetric data, and spatial relationships in three dimensions, enabling accurate depth perception and collision detection in teleoperation environments
Solution Approach 2:
The system creates a multi-functional interface that simultaneously provides depth information, spatial mapping, entity tracking, and collision warning capabilities, replacing the limited 2D screen interface with a comprehensive spatial awareness system that handles multiple functions through integrated sensor processing
3Reliability
If the system tracks and evaluates multiple entities in the environment, then user awareness of surroundings is improved, but computational complexity and processing requirements increase
Solution Approach 1:
The system performs preliminary actions by pre-defining entity types, pre-configuring sensor arrays, and pre-establishing evaluation criteria for spatial relationships, so that during operation only data collection and simple comparisons are needed, reducing real-time computational complexity while maintaining high reliability
Solution Approach 2:
The system applies local quality by focusing computational resources on evaluating only the spatial relationships and variables that are locally relevant to the person's current position and task, rather than processing all possible entity combinations in the entire environment

AI summary
The disclosure regards a method and a system for assisting a person in assessing an environment. The method includes selecting a set of one or more entities (1, 2) present in the environment, obtaining coordinates in the environment and extents of each entity (1, 2) of the set, estimating a location and shape of each entity (1, 2) of the set on the basis of the obtained coordinates and extends of the respective entity, determining an area of interest AOI on the basis of the estimated location and shape of each entity (1, 2) of the set, evaluating the area of interest AOI with respect to one or more variables of interest in order to evaluate a deviation between a current state of the area of interest AOI and a target state, and communicating the deviation from the target state to the person using coherent stimuli for stimulating the person's body.
