The invention relates to a data glove, in particular to an outer skeleton precision data glove used for virtual reality man-machine interaction. The data glove includes a thumb structure, an index finger structure, a middle finger structure, a ring finger structure, a little finger structure, transverse offset angle measurement parts and a hand back base plate; the index finger structure, the middle finger structure, the ring finger structure and the little finger structure are same in structure; one end of the thumb structure, one end of the index finger structure, one end of the middle finger structure, one end of the ring finger structure and one end of the little finger structure are all fixed on the hand back base plate; the index finger structure, the middle finger structure, the ring finger structure and the little finger structure are all provided with the transverse offset angle measurement parts. According to the outer skeleton precision data glove, the bending angles of finger joints are accurately measured by three-stage gears and converted into transverse offset angles for external display, the gears and racks are adopted for accurate measurement, and the problem is solved that existing data gloves do not meet the requirement for high precision.
