“…The practicality and scope of USE make it a versatile alternative to experimental creation and control suites such as the Psychtoolbox (Brainard, 1997;Kleiner, Brainard, & Pelli, 2007;Pelli, 1997), PsychoPy (Peirce, 2007;Peirce, 2008), or MonkeyLogic (Asaad & Eskandar, 2008a;Asaad & Eskandar, 2008b;Asaad, Santhanam, McClellan, & Freedman, 2013;Hwang, Mitz, & Murray, 2019), with the specific focus of creating, controlling and analyzing tasks that have the complexity, dynamism, and visual fidelity typical of video games. USE also provides unique solutions to common challenges of experimental control (see 5.2) that set it apart from other active experiment creation suites (Brookes et al, 2018;Doucet, Gulli, & Martinez-Trujillo, 2016;Jangraw, Johri, Gribetz, & Sajda, 2014). The USE SyncBox is a newly developed, dedicated, and inexpensive machine that allows synchronization of different data streams (such as joystick data, eyetracker data, and game data), and can communicate with other hardware.…”
