Real time feedback to improve accuracy of shoots by police officers in a much shorter time

Every little breath, every twitch of your finger, or even blinking too often can cause you to fail, miss the mark and possibly result in a loss of life in the worst instance. 

Shooting a gun or revolver accurately is a precise skill. You might have tried shooting in a video arcade but that is very different from the real-life experience which Singapore police officers have to rigorously train for. They even have to take a yearly revolver shooting test to ensure that they are up to the mark.  

The officers were faring well, with over 90 percent passing the test every year. But the police force wanted to improve the scores – and ultimately boost public safety.

Previously, while warming up before the test, the police officers were only able to see where their shots had landed when the target boards were retrieved at the end of the warm-up shoot or the basic firing shoot. They had to rely on the instructor to give them feedback retroactively on areas they could improve on, based on the instructor’s experience and observation of the grouping of the shots. There was no real-time analysis after each shot was fired.

While most passed the test, the minority who failed could not go back to work on the frontline until they re-took the test and passed it.

Today, officers’ firearm competency can be improved by using a better training system. The Enhanced Live Firing Range System (ELFRAS), a project initiated by the HTX Human Factors and Simulation Centre of Expertise, uses sensors and analytics to improve the shooting accuracy of those taking the test.  

The system not only provides information on the grouping of the shots, but also does real-time analysis of human factor indices such as weapon handling, breathing, shooting posture and stance, trigger motion, gaze fixation and visual alignment, so that timely and targeted training feedback can be provided.

It also has a video-monitor which displays the shots on the target in real time, so officers can see immediately how they have performed.

But beyond that, ELFRAS tactically deploys sensors to pick up minute physiological human factors, which could affect the shot accuracy of the person taking the test:

  1. A weapon sensor attached to the revolver measures if the officer is moving his weapon in the right way for maximum accuracy.
  2. With a pair of eye-tracking glasses, which not only tracks his gaze point and can compute how long he has fixed his gaze on the target, it can even measure how often he has blinked his eyes.
  3. A breathing sensor tells the officer if his breathing is creating “up-down” movements of the weapon.
  4. A posture camera at the firing range captures how the officer is moving his entire body. This can be mapped against a library of good shooting postures.

The data is further analysed and compared against best practices, so the shooter gets recommendations on how he can improve. For instance, he might learn how to adapt his breathing techniques to get better shots. The HTX team is also providing detailed design recommendations for the user interface to provide trainers with a one-glance view of the overall performance, including sufficient shot-by-shot detail so that the trainer can gain immediate insight on the performance gaps. This would enable the trainer to provide timely intervention to the trainee in between shots.

ELFRAS also monitors the shooting performance of officers not just within a single shooting exercise but over multiple exercises as well. With all the data, training pedagogy can be customised to increase the number of marksmen.

Apart from the police force, ELFRAS could be used by frontline officers in other Home Team departments like the Central Narcotics Bureau, and the Immigration and Checkpoints Authority.
