Hosaka 2.0rc2 (23rd December 2025) Tomas Ukkonen <tomas.ukkonen@iki.fi>
=======================================================================

Hosaka 2.0 is still experimental software that tries to modify brainwaves (EEG).
You can increase relaxation, concentration or sleep or use your own EEG-derivative
numbers target state.

Currently, effects to EEG are small and often one gets 0% result and typical
maximum effect is 1% reduction in distance to the target state.

Hosaka 2.0 requires EEG-device to measure brain which is used to optimize and
select audiovisual stimuli which best moves brain towards
the target EEG value (21 comma separated numbers between [0,1] or negative if value is not used)

Hosaka 2.0 supports MindMonitor App (Muse EEG devices) and the LSL protocol
(BrainAccess HALO EEG and other devices).

To use Hosaka with mindmonitor (set computers ip address and port 4545 in mind monitor app),
you can just start Hosaka without command-line parameters:

./hosaka.exe

To use Hosaka with LSL protocol (BrainAccess HALO EEG), you can use commands:

./hosaka.exe --device=lsl
./hosaka.exe --device=lsl --lsl-names='BA HALO 002_HALO_BrainAccess','EEG'

You need to watch stimulus for 30 minutes to 2 hours for significant results
when using fast CPU (I use 32-thread AMD CPU at 5 GHz).

Command "./hosake.exe --help" shows more options and you can select target state
(default is concentration) using command:

./hosaka.exe --device=mindmonitor --target=-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,1,1


Software also logs various things to a log file hosaka-engine.log. In unix environment
you can see how distance towards target state changes (smaller is better) by
using a command "./get_errors.sh".
