Chris Schlapper, Rob Schultz, and Eric White demonstrate collaborative bi-directional data collection using a laptop and a tablet simultaneously in CAPI interviews at the 2016 Federal CASIC workshops (FedCASIC). This is a methodological and technological advance that allows field interviewers to conduct interviews using a laptop running a traditional CAPI instrument while a respondent holds a tablet whose display is driven by the CAPI instrument. The respondent is prompted to enter his or her answers directly via the tablet interface. These responses are sent back to the laptop in real time and incorporated into the laptop’s data set and instrument. All of this is done without an internet connection.
