Glucoboy

The Glucoboy is a medical device developed by Guidance Interactive Healthcare as a removable accessory for the Nintendo Game Boy Advance. The device is a blood glucose monitor targeted at children with diabetes that provides users with incentives to monitor their blood glucose levels through the use of games and points. Advertised as the "first medical device to interface with a Nintendo Game Boy", the Glucoboy received retrospective attention for its innovative and unusual use as a peripheral for handheld devices. A successor to the Glucoboy called the Didget was released by Bayer HealthCare for the Nintendo DS in 2009 in the UK and 2010 in the US.
