THE PROBLEM: Asthma affects 300 million people in the world. However, adherence to Asthma medication is less than 50% and results in over 450,000 hospitalizations and 250,000 deaths per year.

OUR SOLUTION: mobileHaler is the first low-power, portable electronic platform for measuring Asthma inhaler-usage behavior in patients. mobileHaler measures time and location of inhaler use, and is equipped with a camera to take a picture or a short video of the scenario in front of the inhaler. The data collected from the camera attachment can not only identify the person taking the medication but a video record can also validate if the inhaler was used correctly. Moreover, mobileHaler monitors the quality of inhalation maneuver using accurate flowmeters designed to fit the constraints of a small form factor and ultra-low power inhaler attachment.

MobileSpiro: A Contextual Coaching Spirometer for the Masses

THE PROBLEM: Most current spirometers require an expert technician to ensure correct spirometry. MobileSpiro is the first clinical grade portable spirometer that brings spirometry to masses, by allowing either field nurse or patients themselves to conduct an accurate spirometry.

OUR SOLUTION: We have developed a portable spirometer called ‘mobileSpiro’ which is a combination hardware sensor and Android app with smart algorithms on a smartphone/tablet. The hardware sensor is a very accurate flow meter and meets the tough standards set by ATS and ISO for clinical grade spirometry. The key innovation lies in the mobileSpiro app that: detects common errors in conducting spirometry maneuvers with over 94% accuracy (see publication), provides contextual coaching and live feedback to the patient, and automatically validates the quality of the test performed.

MobileVision: A Self-Use Retinal Imaging System for Eye Screening

THE PROBLEM: An estimated 61 million adults in the U.S. are at high risk for serious vision loss, but only half visited an eye doctor in the past 12 months. We believe this unmet need can be addressed through comprehensive eye screening. However, conventional retinal cameras are big, bulky, and expensive, which makes them unsuitable for widespread screening applications.

OUR SOLUTION: Through the co-design of optical hardware with image processing software such as retinal image registration, fusing, and stitching, the mobileVision prototype enables robust visualization of the retinal from a physically compact device suitable for screening applications.
