The Device
- Millisecond timing accuracy at neural timescales
- Objective cognitive-motor measurement
- Reliable, repeatable performance tracking
- Detects meaningful change over time
- Scales across individuals, teams and cohorts
Unlike traditional cognitive tests that focus on scores or questionnaires, DARTS measures the underlying timing of perception, decision and motor response, revealing how performance actually unfolds in real time.
DARTS enables a clear, structured way to objectively measure cognitive-motor performance using simple visual stimuli and a precise physical response. It was originally developed by neuroscientists for astronaut performance monitoring and has since been adapted for sports, healthcare, education, transport and research.
Each assessment gives a moment-in-time snapshot of how an individual processes, decides and acts, making it ideal for mass screenings, readiness checks, intake assessments and early identification of change.
Once a baseline is established (typically ~25 minutes), quick follow-ups (~15 minutes) provide highly repeatable long-term tracking of improvement, fatigue, recovery or decline.
DARTS works as a standalone behavioural device or can be paired with EMG and EEG systems for deeper neuromuscular and neural timing analysis. Multiple devices can be used simultaneously to ensure fair, consistent testing across teams, classrooms or clinical cohorts.
Most tools start with overall reaction time. DARTS goes deeper, breaking performance into the underlying components that explain why people respond the way they do and how that changes over time.
Why DARTS?
A fast, portable way to understand how someone is performing, right now and how that changes over time.
Whether you're working with athletes, patients, students, pilots or research participants, the biggest challenge is knowing where to focus your time. DARTS provides a clear snapshot of an individual's cognitive-motor state in minutes, then makes it easy to track improvement, fatigue, recovery or decline over days, months or seasons.
DARTS doesn't replace your existing tools; it strengthens them. It sits at the front of your process, helping you use your training, rehab, education or safety systems more efficiently by showing who needs what, and when.
One device, simple workflow, high-resolution data you can trust wherever you need to work.
Same overall reaction time. Different internal structure.
Visual stimulus · Single button response · 427 ms total
Real time
Person A · Higher perception/decision contribution
Person B · Higher motor execution contribution
Person A spends more of their reaction in seeing and deciding. The movement itself is fast, indicating a higher perceptual/decision contribution to the total.
Person B
Higher motor execution contribution
Total: 427 ms
Person B detects and decides quickly, but takes longer to execute the movement. This indicates a higher motor execution contribution to the total.
Same total reaction time. Different internal contributors.
DARTS decomposes reaction time into perception,
cortical decision and
motor execution, showing how identical overall speed can arise from different structures.
Perception (visual)
Cortical decision / control
Motor execution
Sensitivity beyond the average
Early signals show up as variability, then as component compensation.
Mean reaction time can stay stable while the underlying system shifts. DARTS detects subtle changes via distribution shape (IQR / outliers) and then localises them to perception, decision, or motor execution.
Build On DARTS
Not another training gadget. A clean signal that everything else can build on.
Where many tools try to simulate the game itself, DARTS deliberately strips things back to the underlying reaction and decision mechanics. That's what makes it portable, repeatable and ideal as the first step in any performance or health journey.
Millisecond precision
Capture simple and choice reaction times, motor execution latency and response variability in a fraction of a second.
Know what's changing, not just if it changed.
Truly portable hardware
Small, robust and USB-powered. No bulky rigs, no special lighting, no fixed lab required. Test in the spaces you already use.
From locker room to ward to lecture hall.
Sector-tuned dashboards
One underlying engine, different faces. Sports, healthcare, education, transport and research each get tailored views and reports.
Speak the language of coaches & clinicians.
Neuroscience-informed design
Built around established cognitive paradigms so you can trust what you are measuring and compare across time and populations.
Grounded in evidence, not hype.
Pre-training router
Use DARTS data to choose who should go into which advanced training modalities: vision training, decision drills or strength and conditioning.
The assessment layer for your tech stack.
