One of the top questions we are frequently asked is how biometric measurements can be utilized to assess human behavior.
The good news upfront: Biometric sensors offer an almost unlimited application variety to reveal the (sub-)conscious processes underlying behavioral responses. On the flipside, exactly this ample pool of application possibilities is probably one of the reasons researchers often feel overwhelmed or indecisive about which biosensor or combination of biosensors might be the right fit for their research endeavor.
To help you get started, we recently have released a handy sensor chart giving you all the specs you need to know to decide which sensor is most suitable to answer your research question.
Today there is even more guidance coming your way: Drawing from our many years of experience in biometric research, we have pulled together more than 100 application examples grouped by 20 application fields to provide you with an in-depth insight into the rich diversity of multimodal biometric research.
We hope you will be be inspired.
