Police Force (SPF) and HTX have
developed, and are currently testing out, a training system known as the
Enhanced Live Firing Range System (ELFRAS) that is aimed at enhancing firearm training delivery.
The system uses multiple sensors and analytics to improve the shooting
performance of officers undergoing firearm training. This is also in line with
the Home Team’s (HT) drive to better leverage technology to enhance learning
outcomes for HT officers.
2 The sensors capture human factors such
as weapon handling, breathing, shooting posture, gaze fixation and visual
alignment. An embedded Advance Performance Enhancement & Analysis Range
System (APEARS) software analyses data collected through these sensors and
provides real time recommendations to help improve the officer’s subsequent shots.
3 The features of the sensors are as
Handling. A sensor attached to the weapon tracks the
movement of the weapon before, during and after the trigger is pulled. It also
identifies trigger pulling techniques applied by the officer.
b. Breathing. A sensor, fixed at the shooting
lane, tracks and shows whether the officer’s breathing technique affects the movement of his weapon while firing.
Fixation. A sensor in the
form of a pair of spectacles, tracks the officer’s eyes during firing,
including whether the officer focuses on his aiming or blinks his eyes while
Posture.A body posture
camera, fixed at the shooting lane, captures the officer’s body movement and
compares it against the recommended shooting postures.
4. The Human Factors and Simulation Centre
of Expertise (HFS CoE) of HTX worked with SPF to identify the full spectrum of
performance-related human factors indices and to define the engineering design
to instrument the shooting lane with these sensors. Ying Meng Fai, Acting
Director of the HFS CoE said, “The system provides information on the shots and
real-time analysis of human factor indices such as weapon handling, breathing,
shooting posture, and visual alignment. This way, timely and targeted feedback
can be provided to the officers to improve their proficiency.”
one-of-its-kind ELFRAS system also features a target sensor system that performs
automated scoring, captures and displays the location where each shot lands on
the target board in real time. This information, together with recommendations
generated by the APEARS software, is presented on display panels placed beside
and above the officer, to provide both officer and trainer immediate insights
on the shooting performance. This allows the trainer to provide comprehensive
and timely guidance to the officer. The team has also designed an intuitive
‘one glance’ user interface for ELFRAS which enables the trainer and trainee to
rapidly visualise and mitigate critical performance gaps.
6 Beyond this, the ELFRAS tactically
deploys sensors to pick up minute physiological human factors, which could
affect the accuracy of shots. Dr Saravana Kumar, Deputy Director of HFS CoE and
the Project Manager of ELFRAS said, “A sensor attached to the weapon measures if the officer
is handling his weapon correctly for maximum accuracy. The system also has a
breathing sensor to inform the officer of any body- or breathing-related
movements as well as posture detection cameras to determine if the correct
firing posture is adopted by the officer.”
7 Superintendent Joseph Yoong, Head of
the Instructional Technology Division of the SPF Training and Capability
Development Department, and member of the ELFRAS project team, said, “As part
of our efforts to be a learning force with world class training, the Singapore
Police Force leverages technology, such as ELFRAS during firearms training, to
enhance our training delivery and effectiveness, so as to better prepare our
officers for their work at the frontline.”
8 Currently, the project is undergoing a
trial at the Home Team Academy live firing range. The trial which started in
June 2020 is expected to end in February 2021. The trial is conducted with
selected officers undergoing pistol and revolver training. In addition to
soliciting qualitative feedback from officers and trainers, the team is also
analysing the shooting performance of officers in the test group vis-a-vis
officers in the control group. If the trial results are favourable, ELFRAS
could be used by frontline officers in other Home Team departments.
