5% error rate using mobile phones for health data

OK, if I or one of my family are at the emergency room and the doctor starts tapping away on a mobile device to record my medical data, I'm going to tell him/her to change to a pencil. A study in India has found an error rate of 5% for health data entered via mobile. It compares with an error rate of half of one percent for live operator data entry. The research has already influenced at least one tuberculosis treatment center to switch its plans from a menu-driven, mobile phone interface to a live operator.
