🎙️ Episode 24 - Human as Sensor: Eye‑Tracking, Cognitive Load & Human‑AI

In this episode of the ReeThink Podcast, Rudi talks with Aladar Tepelea (CEO) and Dr. Christian Kusmitsch (CTO), co‑founders of Mindset Technologies, about how our eyes, body signals and context can turn humans into high‑resolution sensors for the next wave of human‑AI systems.

Christian is a neuroscientist in psychophysiology and cognitive performance; Aladar comes from finance and systems thinking, and together they’ve built a neurotech company that measures cognitive load, stress and focus in real time using eye‑tracking, head and body posture, and biofeedback in environments with zero tolerance for error: race car cockpits, aviation, control rooms, elite performers and even professional musicians.

We explore why people “choke under pressure”, what’s happening in the brain when you over‑engage and try too hard, and how eye movements, blinks and pupil dynamics reveal whether you’re in flow or cognitive overload – and how Mindset’s “Biofeedback 3.0” stack turns those subtle signals into actionable insights for coaches, trainers and operators.

From there, we widen the lens to the emerging “human as sensor” paradigm and the future of non‑invasive brain‑computer interfaces (BCI): comparing invasive BCIs like Neuralink with high‑resolution eye‑tracking and multimodal sensing, why gaze may become the fastest, most intuitive interface in the age of “physical AI”, and what this means for the ethics of deploying AI and neurotech in defence, industry and everyday life.

You’ll also hear:

• Why musicians can train for thousands of hours without burning out, while esports players often crash by 18 – and what that teaches us about stress, recovery and motor control.
• How Mindset’s software layers on top of devices from Pupil Labs, Tobii and others to interpret fixations, saccades, blinks and pupil size as indicators of cognitive load and situational awareness.
• Why only fixations (not fast saccades) actually carry visual information, and how mis‑labelling these events breaks most off‑the‑shelf analytics.
• How head movement, skeleton tracking and heart‑rate variability can refine models of arousal, attention and overload beyond what eye‑tracking alone can do.
• Why EEG is still hard to use outside the lab, and how AI helps clean artifacts and tune filters both for EEG and high‑frequency eye data
• The coming shift from large language models to world models, and why Jan LeCun, Elon Musk and others see real‑world sensors as the next big frontier.
• A deep ethical debate on AI, weapons systems, social media algorithms, cognitive overload and children’s brains – and why “human‑centred” design must be more than a buzzword.
• The long‑term vision: applying the same bio‑signal insights to healthcare, early detection of conditions like Alzheimer’s, stress‑related disease and workplace wellbeing.
