What do I need to use PEER?
PEER runs on any iPad or iPhone running iOS 10 or later. You will need an Apple ID in order to purchase the app. You will also need a MUSE headset from Interaxon (we recommend the 2016 model), and a computer (Mac or PC) to analyze your results.
In what format does PEER output its data?
PEER stores data in comma-separated values (CSV) files. It divides the data so that each sample has its own row, and the values for that sample are presented in the columns.
What should I do with my CSV-format output file?
Many different programs can handle PEER’s CSV output. You should be able to choose whichever one works best for you. One prominent option is MATLAB.
How do I know if PEER can do my experiment?
PEER is optimally suited to handle any experiment that fits within either the “Oddball” or “Go-No-Go” research paradigms. However, it also features a raw EEG data recorder that could potentially be used for almost any experiment that involves the collection of EEG data.
What if I want to use subjects who are colour blind?
PEER can be configured to use any selection of the colours in our palette, so you can avoid any colours that are problematic for your subjects.
How does PEER affect the battery life of my iPad/iPhone?
We recommend that you charge your device fully before use, as PEER will increase battery usage. A fully-charged device has enough power to complete many rounds of testing.
What about the MUSE battery?
In general, the battery for the MUSE will last longer than the battery for your iPhone or iPad. According to Interaxon, it should last for about five hours. However, we recommend that you charge it fully before beginning testing as well.
How much free space do I need to have on my device to store recordings?
PEER needs a significant amount of free space for data storage. We recommend that you have at least 100MB of free space per test subject.
What are the technical characteristics of the MUSE?
