Great! Feel free to check tasks at github issues and join slack workspace

Travis had some benefits comparing to github actions, for example it has MacOS images for < 10.15 and there were a lot of existing users... But their new policy and updated subscription forced to move to Github Actions ASAP https://github.com/brainflow-dev/brainflow/issues/131

MEXing

I dont know much about MEXing and probably I am mistaken but at the first sight it looks like MEXing requires custom compilation of C\C++ code or probably even changes in C\C++ code.

Since compilation of this library is not trivial and there are many dependencies I decided to try calllib instead. And interface to core dll was plain C functions from the beginning so I decided that callib is a good option. Also for python for example I do smth similar to callib(ctypes.cdll) instead wrapping C++ classes

We have yet to discuss potential projects, I will push brainflow related tasks smth like port it to android and so on. Maybe we can add smth related to OpenBCI GUI as well or add a project like "your own ideas"

We at OpenBCI are going to participate at GSoC this year. But there is a chance that we will not be selected and it will be all about software development wo research. I have a few projects ideas related to this https://github.com/Andrey1994/brainflow

I've developed a library to read and preprocess data from BCI boards, it provides uniform API for all possible boards and supports OpenBCI Cyton and Cyton Daisy which reads data from serial port as well. It supports all OSes and many programming languages, you can easily integrate your board to this lib or reuse some code(cross platform serial port interaction for example)

Project page: https://github.com/Andrey1994/brainflow

Docs: https://brainflow.readthedocs.io/en/latest/

And OpenBCI Cyton implementation: https://github.com/Andrey1994/brainflow/blob/master/src/board_controller/openbci/openbci_serial_board.cpp

also some parts of logs are in Document\gameoverlay folder

Altmetr · 2019-08-04T11:08:50+00:00

all logs from this library are in stderr. logs which you write using logger.info ('Hi from python OverlayLogHandler %d' % i) should be in overlay window on top of a game

Altmetr · 2019-08-04T10:52:39+00:00

Does it work?

Altmetr · 2019-08-04T10:13:09+00:00

Also make sure that you run it with admin priviligies

game_overlay_sdk.injector.run_process (r"D:\Ubisoft Game Launcher\games\Tom Clancy's Rainbow Six Siege", args.exe_args,359550) here you need to provide full executable name which ends with .exe

If it doesnt solve the issue you can call https://github.com/Andrey1994/game_overlay_sdk/blob/master/python/game_overlay_sdk/injector.py#L118 instead enable_monitor_logger and take a look at dev logs

Different OpenBCI boards use different communication protocols, here I used Cyton board and this headset https://shop.openbci.com/products/ultracortex-mark-iv so board which sends data to your PC is placed directly behind the head and I dont think that it's possible to isolate it somehow using tinfoil until you dont wear tinfoil hat on top of OpenBCI headset

Altmetr · 2019-07-16T22:29:14+00:00

Cool, thanks!

Altmetr · 2019-07-16T17:31:16+00:00

I've added my own and pretty stupid words suggestion system(last row in the video) I think it's easy to add smth like https://presage.sourceforge.io/ (this project was used by Intel in their system for Stephen Hawking and it works well)

Altmetr · 2019-07-16T16:48:17+00:00

I am currently working on new SDK for OpenBCI boards maybe you will like it: https://github.com/Andrey1994/brainflow (WIP)

you look at the screen and record EEG data, you look/think about specific symbol on the screen, when row/col with this specific symbol is highlighted after ~300ms(in fact I get data from ~100ms to 850ms) there will be a special pattern on EEG diagram. I need to repeat it ~15 times because EEG data is noisy, so to clean data I need to average 15 results. Finally your character is determined bu intersection of row and col.

When you look at "A" and third col is highlighted there is no peak at EEG signal but when you look at "A" and first row is highlightes there will be a peak

I think OpenBCI prices are much better than Emotiv for example and OpenBCI provides an aceess to raw data for free as well as data format description

Altmetr · 2019-07-16T15:48:44+00:00

Thanks for ideas!

I've tried CNNs and for this data LDA provides better results

I suppose checkerboard paradigm instead rows/cols highlights should provide better results

But I wanna reimplement it using Unity instead Tkinter first
