Record Response Times With a RESPONSEPixx Button Box
This video guide is an introduction to the RESPONSEPixx button box, using a data acquisition and synchronization system from VPixx Technologies and our MATLAB-compatible API. Use scripting to cue and record button presses, and to calculate response times relative to a key video event.
Button presses recorded with a RESPONSEPixx button box and a data acquisition device from VPixx Technologies are synchronized with microsecond precision to video refresh.
Button presses recorded with a RESPONSEPixx button box and a data acquisition device from VPixx Technologies are synchronized with microsecond precision to video refresh.
The guide first includes a presentation of the construction and functionality of our electronic RESPONSEPixx button boxes and their connection with data acquisition devices, including the DATAPixx, PROPixx, VIEWPixx and VIEWPixx/3D. MATLAB-compatible scripts are provided, and it is possible to follow along the video instruction.
After watching a presentation on the construction and functionality of the RESPONSEPixx, we will write a script in MATLAB that is able to record button presses during a reaction time experiment. We will write the script in three sections and learn key concepts along the way.
Perform basic interactions with your data acquisition device.
Record and use a digital input log.
Restrict recording to specific button presses and cue participants to valid response choices.
