AR Wearable Control for Personal Mobility Obstacle Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Personal mobility systems (PM systems) face operational challenges and safety risks due to limited controls, lack of performance feedback, and absence of obstacle detection or avoidance systems, exacerbated by the complexity of urban environments and user training deficiencies.
Innovation Solution
Integration of augmented reality (AR) wearable devices with PM systems to provide centralized telemetry data, navigation information, and obstacle detection, using sensors to modify performance characteristics based on virtual objects in the user's field of view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional controls and performance indicators are incorporated into PM systems, then user experience and safety are improved, but device complexity increases making it infeasible or unsafe
Solution Approach 1:
The patent uses an augmented reality wearable device as an intermediary to display performance indicators and provide controls. The AR device receives data from the PM system's sensors and processors, then presents this information through transparent displays that overlay the user's field of view. This mediator approach allows complex information to be conveyed without adding physical complexity to the PM system itself.
Solution Approach 2:
The patent moves the display interface from the traditional two-dimensional physical controls on the PM system to the three-dimensional spatial domain using AR technology. Virtual controls and indicators are positioned in the user's field of view at various depths and locations, allowing interaction through head movements and gestures rather than physical buttons or levers.
2Ease of operation
If AR wearable devices are used to display performance indicators and controls, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The AR wearable device serves multiple functions simultaneously: it displays performance indicators (speed, battery level, motor temperature), provides control interfaces (acceleration, braking, steering), and offers navigation assistance. This multi-functionality consolidates what would otherwise require multiple separate devices or complex physical controls into a single wearable unit.
Solution Approach 2:
The patent replaces mechanical control interfaces (physical buttons, throttles, switches) with virtual controls displayed through the AR device's transparent display. Users interact with the system through head movements, gestures, or voice commands rather than manual manipulation of mechanical components, reducing wear and maintenance requirements.
3Reliability
If sensors and obstacle detection systems are added to PM systems, then safety is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines multiple sensor functions (obstacle detection, navigation, performance monitoring) into a single integrated AR wearable device. The device incorporates cameras, depth sensors, and processors that work together to detect obstacles, map the environment, and provide real-time feedback to the user through augmented reality displays.
Solution Approach 2:
The AR device uses its own sensors and processors to detect obstacles and provide navigation assistance independently, then communicates this information to the PM system. The wearable device serves itself as both the detection platform and the display interface, reducing the need for additional dedicated sensors on the PM system itself.

AI summary
A method of controlling a personal mobility system includes displaying a virtual object on an augmented reality wearable device, the virtual object being located in a position in the field of view of the augmented reality device corresponding to a position in the real world. Proximity of the personal mobility system or a user of the personal mobility system with the position in the real world is detected. In response to the detection of proximity, a performance characteristic of the personal mobility system is modified.
