Pack&Go is a remote experiment testing and data collection solution under development by VPixx Technologies. Pack&Go runs MATLAB/Psychtoolbox experiments developed by the vision and psychology research communities. The Pack&Go solution provides a high-performance computer architecture for executing Psychtoolbox code remotely. A vetted participant equipped with the correct links and credentials can access the experiment online and stream it to their browser on demand. The participant's technological requirements are relatively low: the participant will not need to download files to their device or meet specific hardware requirements aside from having a stable internet connection. Pack&Go records data files generated during the execution of the scripts programmed by the researcher, including formats such as .csv and .mat. The data files are stored on a secure server alongside anonymized participant information and information about the network's quality during the data collection session. When one or more participants have completed the online study, the experiment manager can download the data locally and analyze it, much in the same way as if the researcher had run the experiment on a local computer.

VPixx Technologies has worked since 2001 developing innovative hardware and software solutions to meet the needs of vision scientists and the extended research community. Pack&Go's development emerged from our long tradition of developing products based on continuous discussions with our customers and in conjunction with early-adopting labs willing to serve as guides for our development. Work on Pack&Go began in 2020 in collaboration with Dr. Caroline Blais and Dr. Daniel Fiset from the University of Quebec in Outaouais (UQO).

With Pack&Go, VPixx Technologies will enable researchers who use Psychtoolbox to retain the ability to design their complex experiments and stimuli and run them online, maintaining similarity with the xperiments they usually run in their laboratories).

The satellite session's objective is to demonstrate the project's current state in a live demo and obtain early feedback from the community.
