Ah, thanks! It even looks like Pure Data is already embedded (says it's linux-only for now). According to Pd's homepage it looks like you can even use "externals, i.e. objects developed in another programming language" as part of your workflow.
Interesting. So am I right to assume that these devices can detect a range of emotions? It would be fascinating to incorporate some kind of iterative feedback loop into a work of art.
The features mention "Extension language support" that lets a user write programs to generate music / modify songs. Anyone care to elaborate on this or provide some examples of extension languages (maybe integration with ChucK or Max/MSP)?
What kind of data can monitors like this actually collect out-of-the-box? I know that you can train a system to recognize some pretty high-level abstractions based on individual neural activity, but how reliably would a similar pattern-recognition mechanism work across a larger population?
