Wireless indoor positioning system (IPS)

InTrack is a real-time, wireless indoor positioning system (IPS) for real-world research scenarios that require great comfort and unobtrusiveness for the user, as well as an agile setup and outstanding signal quality for the researcher. This indoor mapping technology is composed by a pendant (Tag) that is placed on the participant like a necklace in less than two seconds, allowing total freedom of movement; and by 5+ beacons (Anchors) that are easily placed in the walls of the area to cover (>200m2). The automatic calibration of the Anchors grants an easy and fast process to define its position. 

InTrack comes with the Bitbrain Software Kit for data acquisition and programming, which has a large compatibility with real-time I/O and third-party data processing (LSL, Matlab, Python, BCI2000, OpenVibe, etc). Also, by acquiring SennsLab, it can be seamlessly synchronized with other human monitoring technologies such as ExG, GSR, eye trackers, among many others.

Main features

Wearable and mobile
Comfortable pendant device easy to set up in less than 2 seconds and simple set up of the Anchors.
Advanced technology
Fusion of time of flight (ToF), signal strength (RSSI) and inertial data to improve the accuracy of real-time positioning.
Automatic calibration
Easy and fast process to define Anchors’ position, without manual procedures.
Mechanical support
Ultralight and unobstructive Tag to allow total freedom of movement, and compact Anchors that are easily placed on the walls thanks to the magnetics bases.
Connectivity and storage
Bluetooth Low Energy technology positioning streaming or local SD storage.
Swappable and rechargeable batteries with 8+ hours of streaming and local SD storage.

Main components


Wireless, comfortable and ultralight pendant (72g) that can be self-placed by the final user in less than two seconds as a necklace allowing total freedom of movement and unobtrusiveness. Bluetooth streaming and/or on-board SD storage.



The beacons (Anchors) are easily placed on the walls of the area to cover (5 Anchors to cover >200m2) thanks to magnetics bases. The automatic calibration of the Anchors grants an easy and fast process to define its position. The area to cover can be extended to 600m2 (or more) by using a Coverage Extension Kit, which includes an additional package of 5 Anchors.

How to use it

The pendant (Tag), is placed on the participant like a necklace allowing total freedom of movement. The beacons (Anchors) are easily placed on the walls of the area to cover (>200m2) thanks to magnetics bases. The automatic calibration of the Anchors grants a fast process to define its position. It comes with an intuitive, powerful software platform to collect data with the help of visual cues to assure quality montage and monitoring.


  1. Preparation: Upload the map of the area to be tracked in the software and indicate where you will place the Anchors in a numbered way.
  2. Set up: Place the magnetic bases of the Anchors on the walls as indicated in the software. Turn on and place each Anchor in its respective base (the Anchor number must match the number previously specified in the software).
  3. Calibration: Follow the instructions in the software which will indicate that you must approach each Anchor to execute the calibration correctly.
  4. Recording: Turn on and place the Tag, with the SD card inserted in the device, on the person's neck and start recording. It is recommended to check the calibration again.
  5. Storage: Easy to transport (everything fits in its small suitcase) and no maintenance is required.
