UAV Feedback Control System for Visually Impaired Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack effective methods to provide personalized feedback to users with disabilities, such as visually-impaired individuals, using unmanned aerial vehicles (UAVs) for navigation and obstacle detection, relying on manual assistance or inadequate technology.
Innovation Solution
A control system that determines a specific assistance mode for a user account, specifying operations for UAVs to collect environment data and corresponding feedback processes, which are then applied through a wearable feedback system, such as vibrational or visual feedback, to assist users in navigating their environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual assistance or inadequate technology is used for navigation, then device complexity is reduced, but navigation safety and obstacle detection effectiveness deteriorate
Solution Approach 1:
The patent introduces an unmanned aerial vehicle (UAV) as an intermediary device between the user and the environment. The UAV autonomously navigates and detects obstacles, then relays this information back to the user through a feedback system. This intermediary approach provides reliable navigation safety without requiring complex processing on the user's end, as the UAV handles the complex sensing and navigation tasks in the environment.
2Loss of information
If real-time environmental feedback is provided through wearable systems, then user awareness of obstacles is enhanced, but information processing requirements and system complexity increase
Solution Approach 1:
The system segments the information processing tasks between the UAV and the wearable feedback device. The UAV is responsible for collecting and processing environmental data (sensor data, obstacle detection, navigation), while the wearable device only needs to receive and present this processed information to the user. This segmentation reduces the information processing burden on the wearable system and makes the overall system more manageable.
Solution Approach 2:
The patent implements a closed-loop feedback system where the UAV continuously monitors the environment and provides real-time information back to the user through the wearable device. This feedback mechanism ensures that the user has current environmental awareness without requiring the wearable system to perform complex autonomous analysis, as the UAV handles the environmental assessment and simply communicates results back to the user.
3Adaptability or versatility
If personalized assistance modes are implemented for different user needs, then user-specific navigation requirements are met, but system adaptability requirements and configuration complexity increase
Solution Approach 1:
The system implements dynamic assistance modes that can be adjusted based on user needs. The control system receives user input (such as disability type and navigation requirements) and dynamically configures the UAV's operations and the feedback device's presentation methods. This dynamic adaptability allows the system to personalize assistance without requiring completely different hardware configurations for each user type.
Solution Approach 2:
The patent designs the UAV and feedback device as universal platforms capable of serving multiple user types through software configuration. Rather than building specialized systems for each disability type, the universal system can be programmed with different assistance modes (e.g., visual feedback for blind users, auditory feedback for hearing-impaired users) that adapt to various user needs through software rather than hardware changes.

AI summary
Described herein is a control system that facilitates assistance mode(s). In particular, the control system may determine a particular assistance mode associated with an account. This particular assistance mode may specify (i) operations for an aerial vehicle to carry out in order to obtain sensor data providing environment information corresponding to a location associated with the account and (ii) feedback processes to provide feedback, via a feedback system associated with the account, that corresponds to respective environment information. The control system may transmit to the aerial vehicle an indication of the particular operations corresponding to the particular assistance mode and may then receive environment information for the location associated with the account. Based on the received environment information, the control system may apply the specified feedback processes to initiate feedback in accordance with the particular assistance mode via the associated feedback system.
