Biometric storyboards are approaches that combine quantitative physiological measures of player arousal with traditional observation-based user research methodologies. The biometrics-based approach enabled researchers to discover latent issues related to players’ feelings, immersion, and gameplay experience and, in certain categories of issues, reveal up to 63% more issues than observation alone.
The Biometric storyboards are drawn on (1) a player’s physiological arousal signals (GSR), (2) player post-session interviews to explain 'why' the change in their GSR occurred, (3) players’ self-drawn diagrams of their gameplay experience and (4) Observation of player gameplay behavior (or context).
The main challenge of this approach is how to visualize the biometric data and interpret them.

iMotions Biometric and Eye Tracking Platform
iMotions is a flexible software program that allows the synchronization and visualization of multiple streams of data from different sources. The program can read data from a variety of commercially-available physiology sensors. With the right upgrades, it can also estimate emotions based on facial expression (specifically, by automated detection and analysis of facial action units).
How to Use it?
Setup Study: Design your study to fulfill your specific research questions. Setup participants, stimuli, sequencing, questions, segmentations, groups
Connect Sensor: Plug-and-play those biometric sensors needed to carry out your research and/or integrate any third-party sensors via the API Module
Collect Data: Present stimuli & record data from all biosensors connected to the participant, make live (and/or post-processing) annotations
Analyze Data: Make as many reports as needed to analyze your data, individually and/or aggregated visualizations and raw data exports
Facial Expression Recognition
And other 3rd Party Sensors

AFFDEX EPRESS is an automatic Facial Action Coding System with a scale. It is built based on groundbreaking research out of MIT Media Labs, and offers researchers ways to analyze and capture emotion.
The technology employs sophisticated computer vision algorithms to capture and identify emotional reactions to visual stimuli. Affdex is easy to use, anywhere. One can use it with only a webcam and there is no software to install. It is unobtrusive and portable.
Affdex Express technology interprets emotional expressions from users’ faces as they view content—in their homes, offices, or on the go. Researchers can use Affdex Express to conduct survey questions. This ability combined with analysis of user emotional reactions forms a good way to triangulate different methods to understand the impact of content on users.
