An Application Programming Interface for a Brain-Computer Interface using two NeuroSky MindWave devices

Neurosky MindWave headsets offer the possibility of using them in various software developments such as a Brain-Computer Interface. However, these factory headsets only allow one connection for each device. This avoids the possibility of developing applications where two users each have to interact with their headset to the same computer at the same moment in time. Considering this aspect, the present investigation develops an Application Programming Interface (API) for a Brain-Computer Interface through the use of two Mindwave Neurosky headsets at the same time. The research designed and implemented a two-person attention game to test the operation of the two headsets. The results of the experiment were satisfactory since the API did not generate conflicts during the connection of both headsets, in addition the usability level of the application was cataloged by the users with 92.67 SUS points. In this way, the API allows applications to be developed that receive signals from two diadems.
