Assessing emotional and spontaneous reactions of users.
What is it?
Hard- and software tools do enable eye tracking, measure brain wave activity, detect facial expressions, etc.
Compatible with most commonly used hardware devices (e.g. off-the-shelf EEG tracker).
What are the requirements?
Hard- and software setup.
What is it going to do for me?
Augment insights from an interview by getting different inputs (EEG, eye tracking, facial micro-expressions, audio analysis, …).
This can be used to take out or detect bias, pick up contradictions in body language vs response or detect non-verbal cues.
What are the limitations?
Most hardware setups are intrusive and intimidating and will induce a ‘guinea pig’-feeling which might manifest as bias.
There are non-intrusive software applications (e.g. emotion analysis in a video chat interview) and hardware setups (e.g. camera setup to eye track and record interaction with a prototype).
