Measuring Electrodermal Activity to Capture Engagement in an Afterschool Maker Program

In this paper, we describe a new approach for exploring individual participants' engagement in youth maker activities. Participants were outfitted with wearable first person point-of-view still-image cameras and wrist-based electrodermal sensors. The researchers analyzed the recorded electrodermal data stream for surges in skin conductivity and compared them with the corresponding photographs based on their time-stamp. In following with prior work, these surges were interpreted as moments of engagement. A comparison sample was created to look at moments that lacked this psychophysiological marker. Results indicated that the two participants had both shared and divergent engagement with activities such as soldering, assembling, and programming.
