Abstract: An apparatus is used to measure movement performance of a user undergoing firearm combat training. A light emitter emits a light signal along a beam path traversing over a starting location such that the light signal is interrupted by a user at the starting location. A target device initiates a visual representation of a threat directed towards a user at the starting location. A light detector detects a non-interference condition of the light emitter in which the light signal along the beam path is not interrupted at the starting location. A controller monitors the light detector and determines when the user has moved away from the starting location into the non-interference condition of the light emitter. The controller may also measure an elapsed time between activation of the target device and determination of the non-interference condition of the light emitter.

Abstract: There is described a method for coaching a breathing exercise to a user using a computing device. The method provides a sequence of user instructions for the breathing exercise and determines an expected pattern of breathing intensity from the user in accordance with the sequence of user instructions.
