The study of human learning of action sequences involving motor precision components is traditionally conducted in an in-person laboratory setting. However, the ongoing COVID-19 pandemic places a unique challenge on researchers studying this. To continue research during the pandemic, VLEARN (Virtualized Learning) was developed to allow users to both develop and complete virtual motor sequence tasks. VLEARN provides a web-based environment for experiment design, creation, and execution. Prior to COVID-19, two maintenance tasks were developed, a hard drive replacement (previously conducted in-person) and a pipe cleaning (which has been stopped due to the pandemic but was planned to be conducted in-person later). By virtually implementing these two tasks, VLEARN allows researchers to examine the underlying human cognitive-motor processes during learning of action sequences involving various levels of motor demands. Although VLEARN does not exactly replicate the real-world settings, relative to the actual experimental platform, it provides several critical advantages including more precise, real-time data collection, and the capability to enroll a larger pool of participants who can be remotely tested. VLEARN also enhances data processing by accelerating it and also avoids errors due to manually encoding the action sequences to assess performance. Qualitative and quantitative methods will be used to measure user-experience and efficiency of data collection with VLEARN. First, after completing both maintenance tasks, participants will complete surveys from which usability and mental states scores will be derived in order to assess user-experience. Second, researchers who conducted the in-person experiment will also be surveyed for user experience and data accuracy relative to the original data set collected in-person. It is expected that VLEARN will be favorably assessed by most users. Future work includes assessing this virtual experimental platform via additional user-validity and motor sequence tasks.
