Abstract
Various systems and methods are provided for injection training by collecting, processing, analyzing and displaying measured information associated with the delivery of an injection. Sensor-based measurements of a syringe'"'"'s position and orientation in three-dimensional space are obtained and processed to provide metrics of a trainee'"'"'s injection performance. The measurements can be combined with a digital model of a training apparatus to deliver a computer-generated, graphical depiction of the training injection, enabling visualization of the injection from perspectives unavailable in the physical world. The training injection execution, as reflected in the measured sensor-based data, can be reviewed and analyzed at times after, and in locations different than, the time and location of the training injection. Additionally, injection training data associated with multiple training injections can be aggregated and analyzed for, among other things, trends in performance.
