What is adaptive intelligent training?

Adaptive intelligent training optimizes the learning

process by:

• Adapting to individual needs. Training is tailored to an

individual and progresses them as quickly as possible

along their unique learning path

• Applying AI to make training more effective and efficient

over time with scalable techniques

Our training platforms empower the individual and the

organization to deliver peak performance.

What are the benefits of adaptive intelligent training?

Adaptive intelligent training lets you:

• Achieve a higher skill level across trainees in the same

amount of time by holding training time constant

• Train groups faster when they have the same skill level by

holding training criteria constant

With adaptive intelligent training, you can reduce training

costs and improve skill levels across your organization.

Training features

Our training systems create adaptive intelligent training with:

• Analytics that characterize your simulation data

• Agents (AI) that act as virtual patients and teammates

• Interfaces that offer special capabilities, such as speech

and XR

• Scenario builders that help you author and

generate scenarios

We have applied our adaptive intelligent training to:

• Wellness. Our work integrates the latest psychological

advances to help people be well

• Cognitive load measurement. We take our research out of

the lab and into the field to measure cognitive load

• Decision support. Our projects help medical personnel

make critical decisions that can save lives

• Autonomy. Our solutions have autonomy to keep humans

out of harm’s way

• Hands-free data input. Our hands‑free data input solution

automatically captures data during treatment so your

personnel can focus on the patient, not data entry

Projects

VITAMMINS. Virtual patient simulation and tutoring system

for teaching and assessing trauma care skills

EFECTIVE. Comprehensive virtual environment for training

medical and operational skills for austere, mass casualty

environments

MARC. Augmented reality simulation of medical wounds to

improve realism

TMT. Manikin accessory for classroom and field exercise

tourniquet skill training

STAT. Multi‑platform, screen‑based practice environment for

single‑patient trauma care

SHIELD. Offers training exercises and self‑assessments that

help Marines cope with stress

RELAX. Helps Veterans improve anger management using

cognitive behavioral therapy

fNIRS. Small, unobtrusive sensors that track measures of

cognitive state

EPIC3. Helps medical personnel quickly and accurately

predict traumatic injury and other patient outcomes

BRACE. Integrates proven sensing and autonomy

capabilities into a modular hardware/software applique so

platforms can safely evacuate combat casualties

CAPTURE. Hands‑free interface that streamlines the capture

of medical information

Adaptive medical and patient care training: VITAMMINS

VITAMMINS classifies a medical professional’s skill and

adapts content to meet their learning needs as they progress

through their training session. Medical professionals trained

with the benefit of VITAMMINS skill models and adaptive

training algorithms can deliver a higher quality of care.

We worked with Professors Frank Ritter and Chris Garrison

of Penn State to create detailed skill models using our MAST

annotated skill trees to rapidly train deep knowledge about

complex procedural skills, including challenges that medical

personnel might face.

This detailed, adaptive training better trains medical

professionals to meet the demands of tomorrow.

The VITAMMINS medical simulation user interface was designed as a solution for the military medical domain, but is now used at Penn State to create

scenarios and cues for trauma nurses.

Junctional tourniquet training: TMT

TMT allows pre‑hospital medical providers to practice using

junctional tourniquets on manikins, improving medical

efficacy and reducing training costs.

TMT includes a sensor system

linked to a virtual mentor that

provides students with automatic,

objective assessment and feedback

during training. A mobile app

offers students refresher training

during deployment or when

a manikin is not available for

practice.

TMT works with multiple types of

manikins and can adapt to future

tourniquet technology advances.

Trauma assessment training: STAT

With STAT, students learn the steps and concepts of trauma

assessment so well that these procedures become second

nature. After mastering our virtual training, students know

what to do, when to do it, and can perform quickly when

they face real‑life medical emergencies.

We teamed with Professor Frank Ritter of Penn State to

develop STAT, our computer‑ and tablet‑based trauma care

assessment solution. STAT provides an interactive virtual

patient so students can transfer the skills they learned in the

sim center to real‑life medical scenarios.

With Penn State’s D2P2

tutoring architecture,

we used STAT to create

an intelligent Trauma

Nurse Tutor for the US

Air Force.

Training procedures in context: EFECTIVE

EFECTIVE is the DoD’s first comprehensive virtual system

to train the personnel that support medical missions. We

adapted it to train civilian personnel responding to mass

casualty incidents. EFECTIVE lets a student safely visit—and

revisit—a challenging environment, better preparing medical

professionals for real‑world scenarios.

EFECTIVE captures important decision‑making themes based

on existing policies and the past experience of military

medical personnel. The simulation automatically assesses

student proficiency against objective performance metrics

linked to these themes.

EFECTIVE also integrates with VIRTUOSO, our XR software

development kit, to support training peripherals, such as VR

headsets and physiological sensors.

resources, and interpreting mission requirements to make decisions about casualty care.

Tactical combat casualty care training: MARC

MARC provides augmented reality (AR), in‑situ, tactical

combat casualty care training and assessment during live,

force‑on‑force training.

An ongoing US Army study, Squad Overmatch‑TC3, found

that Warfighters lack access to realistic tactical combat

casualty care (TC3) simulations. MARC addresses this gap

with commercially available AR technologies that portray

realistic, virtual wounds overlaid on live actor patients.

Our MARC simulation technology offers organizations a

cost‑effective and realistic alternative to staid classroom

exercises. MARC better equips medics with the skills they

need to simultaneously manage combat and lifesaving

interventions.

Medics provide mock medical treatment to a live actor patient in a treatment tent (left). MARC’s AR uses real-time human pose estimation and wound

rendering to make training more realistic (right).
