Eye-tracking technology aims to measure the point of gaze or the movement of the eyes with eye tracking devices, often to study human behavior out of the lab. Researchers are often challenged when subjects do not respond honestly or accurately due to artificial environments or discomfort. If the research aims to study real-world behaviors, lab situations or observations can change each subject’s behavior, reducing the ecological validity of the data. Read more
If people measure biosignals, they are usually connected via cables to a computer or at least a notebook, which is also pretty bulky. By using a mobile device like an android based smartphone or tablet, along with a wireless system, biosignal acquisition can be much more portable. Signal acquisition could be performed nearly everywhere. A software framework was recently created for g.Nautilus, providing functionality to measure biosignals and do some basic processing like applying digital filters, estimating bandpower or calculating bipolar derivation.
TMS is a magnetic method to non-invasively stimulate the brain. This technology has been used to investigate the connectivity between the motor cortex and corresponding muscle groups for patients with brain damage. Read more
The EEG (Electroencephalogram) can be used as a method to study high-altitude sickness and its influence on the body condition and health of mountaineers. By measuring changes in the beta band following a movement task, information about how acclimatized a person is to the change in altitude can be discerned. Read more
