1. A method to improve performance of an injection technique using one or more signal processors of an injection training system having an anatomically-shaped apparatus and a syringe, the method comprising:

  • providing the anatomically-shaped apparatus, the anatomically-shaped apparatus configured to receive a training injection of the injection technique performed by a user;

    providing the syringe having a needle, a barrel, and a plunger and configured to deliver the training injection to the anatomically-shaped apparatus, the syringe further comprising at least one syringe sensor on the syringe;

    receiving, by the one or more signal processors of the injection training system, sensor-based injection information associated with the training injection of the injection technique, the sensor-based injection information comprising information indicative of the position and use characteristics of the syringe detected by the at least one syringe sensor;

    analyzing electronically, using the one or more signal processors, the sensor-based injection information;

    evaluating electronically, using the one or more signal processors, the analyzed sensor-based injection information relative to at least one evaluation criterion; and

    comparing electronically, using the one or more signal processors, the analyzed sensor-based injection information with at least one performance requirement to determine whether the training injection met the at least one performance requirement;

    outputting by the one or more signal processors, for displaying on a display device during and/or after the training injection, a graphical depiction of the training injection, wherein the graphic depiction includes a digital three-dimensional model of the anatomically-shaped apparatus a location of the needle relative to the digital three-dimensional model of the anatomically-shaped apparatus, and a dynamic position of the plunger in real time, the digital three-dimensional model of the anatomically-shaped apparatus comprising facial anatomical features, wherein the one or more signal processors are configured to alter a view of the graphical depiction to better visualize the training injection; and

    outputting electronically, using the one or more signal processors, based on the analyzed sensor-based injection information, a recommended action to improve injection technique.
