Senior glaucoma patients facing mobility challenges will leverage InnoVision, an automated eyedrop delivery device that uses computer vision to detect the center of the eye and autonomously administer medication.
Inspiration
According to NIH research, 40% of senior patients reported at least one eyedrop problem: misaiming, multiple drops, or tip contamination. For senior glaucoma patients facing mobility concerns, these issues are even more prevalent. Low tech guides such as AutoDrop cost about $8 but still rely on the user’s shaky hand, and higher-end products in the market like Eyenovia’s Optejet are used primarily in clinics and hence are undesirable for individuals seeking greater independence. No current product combines computer vision alignment, automated actuation, and precise single drop metering… all of which InnoVision brings to the table.
How it works
Google’s MediaPipe Face Mesh – an AI model used to detect facial landmarks – is crucial to locate the center of the eye. While none of the landmarks mapped by the model includes this location by itself, InnoVision employs a unique algorithm that extracts coordinates of several landmarks that symmetrically cover the contour of the eye, and averages the values to approximate the center. Once the eye is detected, Proportional-Integral-Derivative (PID) controllers are used to transport the motor – which is connected to the camera and eyedropper – to above the center of the eye. To ensure that the system is at a sufficient height above the user’s face, a unique adjustable mount is leveraged.
UI
InnoVision’s companion app turns clinical precision into everyday ease. The moment the dashboard opens, each prescription appears in 18pt font besides its matching color and progress ring, which turns soothing green when the day’s regimen is complete. A single thumb sized start/stop button toggles the automated dropper, and a gentle haptic pulse confirms that the eye has been dosed. Scheduling follows the logic of a wall calendar where users can tap input medication information, choose days of the weeks, and the app handles the rest by lighting up ten minute reminder banners and synchronizing the timetable to the device in the background. All controls meet WCAG-AA contrast standards and sit within easy reach, so even shaky hands and blurry vision can navigate effortlessly. Lastly, InnoVision takes advantage of the app integration to occasionally push out surveys to collect data on different aspects of the customer experience. This information will be used to iterate and continuously improve the product. Data will only be used for product development, not monetization – the only revenue stream InnoVision focuses on is that of selling the device itself.
