AR Injection-Site Marker for Accurate Self-Injection Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Self-administration of injectable therapeutics is hindered by needle anxiety, incorrect device operation, and fear of accidental needle sticks, especially among device-naïve patients, leading to noncompliance and inaccurate dosing due to lack of proper training and guidance.
Innovation Solution
An AR self-injection training system using a marker adhered to the injection site that provides real-time AR content and error correction, incorporating analgesia and sensor feedback to guide users through the injection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If marker-less AR applications are used for self-injection training, then technological sophistication is reduced, but injection surfaces are too small and non-uniform to support accurate marker detection and tracking
Solution Approach 1:
The patent introduces a physical marker as an intermediary object placed on the injection site. This marker serves as a mediator between the AR system and the small, non-uniform injection surface, providing a sufficiently large and uniform target for accurate marker detection and tracking while maintaining ease of use for patients
Solution Approach 2:
The patent transitions from marker-less AR (relying solely on digital image processing of small skin areas) to marker-based AR (adding a physical dimension with a dedicated tracking marker). This dimensional change from purely digital to physical-digital hybrid enables more reliable AR content placement by providing a larger, more uniform tracking target
2Productivity
If traditional training methods are used for self-injection, then technological complexity is reduced, but training efficiency and learning speed are significantly lower
Solution Approach 1:
The patent implements real-time feedback through the AR system, which provides visual overlays, step-by-step instructions, and performance monitoring during training. This feedback mechanism accelerates learning by immediately correcting errors and guiding users through the injection process, justifying the added technological complexity
Solution Approach 2:
The patent replaces traditional mechanical/in-person training methods with an AR-based digital training system. This substitution enables scalable, consistent training delivery with enhanced interactivity and feedback capabilities, improving training efficiency despite increased system complexity
3Device complexity
If patients self-administer injections without proper training, then device complexity and training requirements are reduced, but incorrect device operation and inaccurate dosing occur
Solution Approach 1:
The patent implements preliminary action by providing comprehensive AR-based training before actual self-administration. The system guides users through practice injections with virtual feedback, ensuring they master proper technique and device operation before treating themselves, thereby ensuring reliable dose delivery while maintaining device simplicity

AI summary
Disclosed is an AR self-injection training system and method of use incorporating a marker specifically designed for device-naive self-injection patients. The marker is designed so that it can be removably adhered to an injection site. Once in position it anchors AR content to the injection site for training. The marker is designed to associate AR content to the injection site for training and allows patient to leave the marker in place and inject to the same site. Providing a system that is able to identify a site of injection and to provide salient instructions streamlines the process of training and makes the transition to using a real-device relatively seamless. The provided embodiments can also incorporate error correction functionality and even local anesthesia or analgesic. Following training, the opening in the marker allows patients to leave the marker in place and inject to the same site.
