7. A healthcare diagnosis training and evaluation system comprises: a virtual patient examination simulator interface module that renders a computer graphics animation of a virtual physical exam diagnostic device and a real-time motory change to an organ or a body part of an animated virtual patient when a user's diagnostic gesture pattern is drawn with a mouse or a finger on top of the animated virtual patient on a display screen, wherein the virtual patient examination simulator interface prompts the user to specify diagnostic prediction indicators for a diagnostics result before invoking the user's diagnostic gesture pattern to initiate a diagnostics test and determine correctness of the user's diagnostic indicators, wherein the real-time motory change to the organ or the body part and the diagnostics test is associated with an ocular motor examination, and wherein the user's diagnostic gesture pattern drawn on top of the animated virtual patient is an “H” pattern gestured over the animated virtual patient's eyes with the mouse or the finger; a test mode selection interface module that generates a user selection menu for a basic linear test mode, a beginner student test mode for dynamic differential diagnosis, and an advanced student test mode for dynamic differential diagnosis; a hypothesis selection and ranking interface module that allows a student to add, delete, rank, or modify a hypothesis in the differential diagnosis list during a health questioning, a simulated physical exam, a simulated medical test, and a simulated medical tests review, wherein the hypothesis selection and ranking interface module generates a differential diagnosis management menu to create or modify a differential diagnosis list for patient condition determination; a virtual patient health questioning interface module that generates a list of health questions selected by a student, an image of a simulated virtual patient, and simulated responses from the simulated virtual patient from the list of health questions, wherein the virtual patient health questioning interface module also incorporates the differential diagnosis management menu to allow the student to create or modify the differential diagnosis list for patient condition determination; a physical exam interface module that enables the student to perform the simulated physical exam on the simulated virtual patient, wherein the physical exam interface module also incorporates the differential diagnosis management menu to allow the student to revise the differential diagnosis list for patient condition determination during or after the simulated physical exam; a hypothesis and medical test association interface module that allows the student to associate the simulated medical test to a particular hypothesis in the differential diagnosis list, wherein the hypothesis and medical test association interface module also incorporates the differential diagnosis management menu to allow the student to revise the differential diagnosis list for patient condition determination; a medical test selection and differential diagnosis commitment interface module that requires the student to commit a current set of the differential diagnosis list for computerized evaluation, while also requiring the student to finalize simulated medical test selections for patient condition determination; a medical test results interface module that generates results of the simulated medical test, wherein the results are reviewed by the student for deducing a definitive diagnosis for evaluation; a treatment and management plan composition interface module that takes the student's input for a treatment and management plan; a student diagnosis evaluation interface module that evaluates the definitive diagnosis, the treatment and management plan, and associated diagnostic reasoning to generate a grading result based on correctness of the definitive diagnosis, the treatment and management plan, and the associated diagnostic reasoning from the student; and a central processing unit (CPU) and a memory unit of a computer system or another electronic device, wherein the CPU and the memory unit execute at least one of the virtual patient examination simulator interface module, the testing mode selection interface module, the hypothesis selection and ranking interface module, the virtual patient health questioning interface module, the physical exam interface module, the hypothesis and medical test association interface module, the medical test selection and differential diagnosis commitment interface module, the medical test results interface module, the treatment and management plan composition interface module, and the student diagnosis evaluation interface module.
12. The healthcare diagnosis training and evaluation system of claim 7 , further comprising a display panel connected to the computer system or another electronic device, wherein the display panel displays computerized user interface information from the testing mode selection interface module, the hypothesis selection and ranking interface module, the virtual patient health questioning interface module, the physical exam interface module, the hypothesis and medical test association interface module, the medical test selection and differential diagnosis commitment interface module, the medical test results interface module, the treatment and management plan composition interface module, and the student diagnosis evaluation interface module.
