Designed for children with diabetes, Glucoboy is a blood glucose meter cartridge for the Nintendo GameBoy. From an interview with inventor Paul Wessel, founder of Guidance Interactive Healthcare:
"My son Luke was diagnosed at age three with Type 1 (diabetes). At about age six Luke began losing his glucose meter way too often. But he knew exactly where his GAMEBOY was, even if it was under the sofa. So I thought – Why not combine the two devices into one."
