Other kinds of data we provide:

Vision data:
We can work with long-range biometrics, meaning we create video datasets with participants at long distances from the camera. This can be across a wide range of demographics including gender, ethnicity, age, and body size. Alternatively, we can look at facial biometrics by working with participants at a close range. Whilst creating these types of video datasets, the demographics we can look at include gender, ethnicity, age, and facial distinctions (eye colour, glasses, etc). Learn more.
