1. An injection device assembly comprising:
a housing;
a syringe assembly at least partially disposed within the housing;
a drive mechanism configured to drive the syringe assembly from a storage position to an injection position;
one or more skin-contact sensors, each sensor being configured to detect contact with skin tissue;
an accelerometer disposed within the housing and configured to output a signal representative of sensed acceleration; and
a processing circuit operably coupled with the one or more skin-contact sensors and the accelerometer configured to:
analyze the signal output by the accelerometer to detect acceleration spikes, and
determine that a first acceleration spike detected in the signal output by the accelerometer is caused by initiation of a dispensing event in which the syringe assembly is driven by the drive mechanism from the storage position to the injection position only when at least one of the one or more skin-contact sensors detect contact with skin tissue at a time when the first acceleration spike was detected.
