Augmented reality system for teaching patient care

A system, comprising:

• a first manikin,
• wherein the first manikin comprises a fetal manikin;
• a second manikin in which the fetal manikin is contained,
• wherein the second manikin comprises a maternal manikin;
• a display unit that displays virtual human anatomy in a manner that visualizes the virtual human anatomy relative to the maternal manikin,
• wherein the virtual human anatomy comprises virtual fetal anatomy, and
• wherein the displaying of the virtual fetal anatomy on the display unit is visually synchronized with:
• (i) changes to a simulated vital sign of the first fetal manikin, causing visually perceptible movement of, and/or deflections to, the virtual fetal anatomy on the display unit;
• or
• (ii) external physical pressure applied to the maternal manikin, causing visually perceptible movement of, and/or deflections to, the virtual fetal anatomy on the display unit;
• or
• (iii) both (i) and (ii);
• a tracking system that tracks the fetal manikin while the first fetal manikin moves relative to the maternal manikin;
• and
• a computing device that co-registers the virtual fetal anatomy with the fetal manikin,
• wherein the computing device co-registers the virtual fetal anatomy with the fetal manikin based on the tracking of the fetal manikin by the tracking system.

An apparatus, comprising:

• a non-transitory computer readable medium;
• and
• a plurality of instructions stored on the non-transitory computer readable medium and executable by one or more processors to implement the following steps:
• tracking a first manikin while the first manikin moves relative to a second manikin in which the first manikin is contained,
• wherein the first manikin comprises a fetal manikin, and
• wherein the second manikin comprises a maternal manikin;
• co-registering virtual human anatomy with the fetal manikin,
• wherein the virtual human anatomy comprises virtual fetal anatomy, and
• wherein the co-registering of the virtual fetal anatomy with the fetal manikin is based on the tracking of the fetal manikin;
• and
• displaying the virtual fetal anatomy on a display unit in a manner that visualizes the virtual fetal anatomy relative to the maternal manikin,
• wherein the displaying of the virtual fetal anatomy on the display unit is visually synchronized with:
• (i) changes to a simulated vital sign of the fetal manikin, causing visually perceptible movement of, and/or deflections to, the virtual fetal anatomy on the display unit;
• or
• (ii) external physical pressure applied to the maternal manikin, causing visually perceptible movement of, and/or deflections to, the virtual fetal anatomy on the display unit;
• or
• (iii) both (i) and (ii).
