A voice activated device for insulin dosage calculations for visually impaired diabetes

Diabetes places dietary burdens on those who suffer from it. Managing these burdens often requires performing calculations. Bolus calculators have been developed to facilitate these calculations, but fail to address accessibility issues presented by visual impairment, often associated with diabetes. The device presented herein is designed to provide an accessible bolus calculator for the visually impaired. This is primarily accomplished through a voice based interface. The user may speak the name and portion size of the food to be consumed. A word recognition algorithm matches the spoken name with one stored in a food database on the device. From the database the quantity of carbohydrates contained in the food are found. This data, along with a blood sugar measurement, is used to compute a recommended bolus dose, which is then presented to the user. It is expected that this device will improve the visually impaireds ability to manage their diabetes.
