Naxon Emotions is a tool to objectively measure and record a person's emotions and cognitive states in real time and at low cost using portable electroencephalography (EEG) headbands.

This real-time emotion recognition system is based on neurophysiological data from EEG, cloud computing and AI.


Measuring concentration and alertness

Naxon Emotions can be used to measure and record in real time the state of concentration and alertness of a person. This record can be viewed on the platform or downloaded in an Excel format for further analysis with other tools.

The possibilities of using these records are multiple, such as providing support and brain correlates to psychometric measures, evaluating clinical interventions, conducting field research in the area of neuromarketing, among others.

While taking data you can post notes using the tools on the right-hand side, adding comments that will be subject to the time of the graph where they were made.

Events: this tool allows to predetermine events, that is, for example, if a person is receiving a certain visual stimulus every 5 seconds, you can predetermine that every 5 seconds the name of that event is automatically marked on the graph so that the event is correlated with the states. You can do so using the options on the right-hand side.
