Technology · Bitbrain
Brain and body signals, recorded in sync with your Tobii.
Bitbrain makes wearable EEG and biosignal sensors that set up in minutes, plus the software that synchronises them with Tobii eye tracking. We specify, install and train on the full range, from a ready-made consumer research lab to a 32-channel research cap.
Consort XPR is an authorised Distributor of EEG, biosignal and software products from Bitbrain.

01 · Start here
One question decides the system: metrics, or raw data?
Bitbrain builds for two kinds of team. Tell us which one you are and the specification follows.
You want answers
Human behaviourMarket research agencies, UX teams and university marketing departments. No EEG background needed. You get calibrated emotional, cognitive and attention metrics per stimulus, ready to compare across participants.
You want the signal
ResearchNeuroscience, psychology, clinical, BCI and engineering groups who process their own data. You choose channel count, electrode type and layout, then export open CSV and EDF files to Python or MATLAB.
02 · Human behaviour labs
Three labs, each built around Tobii.
Bitbrain packages its consumer and UX research labs with Tobii eye trackers. Each includes one year of SennsLab and SennsMetrics licences and online training, and we run the first study with you.
Professional Lab
EEG and arousal
Diadem 12-channel dry EEG with the Ring for skin conductance and pulse. For brand and advertising tests where you already have eye tracking, or do not need it.
Premium Lab
Plus screen-based Tobii
The Professional Lab with Tobii Pro Spark, so every EEG and GSR response is tied to what the participant was looking at on screen.
Mobile Premium Lab
Plus Tobii Pro Glasses 3
The same sensors with wearable eye tracking, for shelves, stores, vehicles and real-world UX. Bitbrain quotes an 8-minute set-up.
Already own a Tobii? Add Diadem and the Ring to it. SennsLab synchronises Bitbrain sensors with Tobii eye trackers, so your existing system becomes a multimodal lab.
03 · Devices
Dry, textile, water-based. Pick by how much signal you need.
Fewer channels means faster set-up and happier participants. More channels means flexible layouts and richer analysis. Every EEG amplifier records at 24-bit resolution with active shielding.

04 · Software
Record free. Synchronise and analyse when you need to.
SennsLite and the SDK come with every device. SennsLab and SennsMetrics are licensed, and are the route to Tobii synchronisation and ready-made metrics.

Build · included
SDK
Open-source C SDK with Python integration, for Windows and Linux. For BCI and custom real-time applications.
Online · licensed
Implicit Response Test
Web-based implicit association and priming tests on brands, packs and claims. No hardware, so samples can be large.
05 · What gets measured
Six signals behind the gaze.
Each metric is calibrated against the participant’s own baseline at the start of the session. A score shows change for that person, which is what makes comparisons between people fair.
EEG
Workload
How much mental effort a task demands.
EEG
Engagement
How involved and present the participant is.
EEG
Memorisation
Effort spent encoding what they see.
EEG
Valence
Approach or avoidance: a leaning towards positive or negative.
GSR
Emotional activation
Sustained arousal or relaxation across a task.
GSR
Emotional impact
The intensity of short, sharp reactions to a moment.
Add Tobii and you know what caused it. Areas of interest, time to first fixation and dwell time sit on the same timeline, so a spike in impact can be traced to the frame, pack or button that triggered it.
06 · Questions
Before you specify.
Does Bitbrain work with my Tobii eye tracker?
Yes. SennsLab synchronises Bitbrain EEG and biosignals with Tobii eye trackers. Bitbrain’s own lab packages are built on Tobii Pro Spark and Tobii Pro Glasses 3, and we can tell you whether your current Tobii model is supported.
Dry, textile or water-based EEG: which should I choose?
Dry (Diadem, Air) for speed and comfort in behaviour research. Textile (Ikon) when participants record themselves, at home or at scale. Water-based (Versatile, Versatile Plus) when you need more channels or a custom layout. Only Ikon Sleep uses gel, and its sensors come pre-gelled.
Can I get raw data?
Yes. Every device ships with SennsLite and the SDK, which export open CSV and EDF files and stream over Lab Streaming Layer to tools such as BCI2000, OpenViBE and NeuroPype.
Who trains and supports us?
We do. Bitbrain requires training for its lab packages, and we deliver it alongside your first study. Our support team answers the same working day.
