Over the past three years we’ve been interacting with others online a lot more, and in person a lot less. On one hand, I’m grateful the online tools exist. Not only would all of my fellow qualitative researchers and I have been out of business without them, but they enabled me to spend time with friends and family I might not otherwise have been able to see.

On the other hand, the level of nuance and engagement we get from online interactions pales next to what we get in-person. So, it’s been great getting back to seeing people face-to-face. I’ve also been very happy to be doing quite a bit more face-to-face qualitative research over the past ten months than in the previous couple of years.

In-person contact provides those all-important non-verbal cues: body language, gestures, facial expressions, and tone of voice. Sometimes you can pick those up on a video call, but not nearly as much as when you’re actually there. Non-verbals are clues to people’s emotional states and attitudes. They can tell you when someone is kidding or being sarcastic, honest or deceptive, anxious or offended. They help build rapport during conversation. This is why I’ve been encouraging my clients to get back to face-to-face research when possible.

I’ve also been making use recently of tools that detect non-verbal cues when conducting online research, specifically online eye tracking and facial coding. Both work through the research respondent’s own webcam, so no additional hardware is required. How can these tools help us?

Eye tracking is useful when conducting research involving some sort of stimulus, such as an advertisement, a package mockup, or a webpage. It can show which elements in the stimulus are drawing attention, and how long people are focusing on those elements.

Facial coding captures involuntary micro-expressions that are not discernable to the naked eye, and that reveal the respondent’s emotional state. Sometimes people aren’t honest about their emotions at a given time, or may not even be aware of them. But micro-expressions give them away.

While it would be overstating to say these tools replicate the advantages of in-person interaction, they do serve to increase the insights we can draw from online experiences – giving us more bang for our research buck.
