GET BETTER TRAINING OUTCOMES WITH DATA
HEAT by VRAI is a human-performance data platform integrated tightly with Varjo Base. Using Varjo's high-precision eye tracking and integrated biometric monitors, HEAT captures what happens during a simulation and displays it in an after-action review dashboard.
The HEAT Starter Kit is available for download for existing Varjo XR-4 Series users.
The missing piece
Analytics layer for synthetic training
Every day, thousands of hours of simulation training are completed across the world. Yet most of the data is lost. Every session generates rich human performance signals: how trainees decide, where they look, how they perform under pressure. Without a way to capture it, that untapped resource disappears the moment training ends.
HEAT by VRAI introduces a data analytics layer to your Varjo training system, turning immersive experience into measurable, repeatable human performance insight.
Capture. Store. Analyze. Visualize.
From Subjective Feedback to Objective Insight
HEAT works alongside your existing Varjo XR-4 Series workflow. It captures eye tracking, biometrics, and event data during each session, stores it securely on-premise or in the cloud, and uses machine learning to surface patterns in cognitive load, attention, and decision timing.
Every session becomes a structured, data-driven debrief. Instructors get objective, evidence-based feedback aligned to training objectives, and data ownership stays with you.
Built to scale
From First Session to Full Program
The HEAT Starter Kit is the entry point into data-driven simulation training. It deploys onto your existing Varjo systems with no custom development and no workflow change, giving you immediate access to human performance data from the first session.
The full HEAT platform expands to multi-source data integration, individual training profiles, and advanced analytics scalable across entire training programmes, helping you assure performance standards, accelerate trainee progression, and reduce training time and cost.
