Biosensors let you know what your senses are derived from?

For a long time academia has been studying how video and audio affect our brains and the body. At present, the study not only occurred in the university laboratory, Dolby's laboratory has conducted its own internal research, that is, how the media triggered the human response. The recent Dolby Laboratories in San Francisco has spent a great deal of time demonstrating the latest developments in its proprietary high dynamic range (HDR) technology.


 In a temporary soundproof living room, a woman sitting on a 64-channel EEG hat is sitting on a leather sofa, a biotherapy cap that is commonly used to measure the electrical activity of brain neurons. On her wrist is a tracker, measuring heart rate and skin electrical reaction, her fingertips also with a pulse oximeter, the room which set up a thermal imaging camera, also observed her skin temperature changes.
 Dolby Laboratories chief scientist PoppyCrum said Dolby tries to better understand the human video and audio experience. The company initially began studying human physiological responses to video and audio in 2012 and created a complete biophysical laboratory in 2015. This room has three screens, at least a dozen speakers. One of the monitors showed a series of videos to the woman on the couch, and the other two showed her reaction data in real time.
 These data are raw data, let the team get information and deal with the data, inform the media on how to make decisions, such as what the scene in the movie so that the audience heart beat faster, what scene so that they produce sweat, or make their cheeks fever What scene or plot makes them fall asleep?
 Dolby is not the first technology company to use advanced sensors to understand how viewers interact with the media. For example, Netflix uses eye tracking techniques to determine the interface redesign decisions and finds that viewers are constantly forced to move their eyes back and forth between the title of a program and the description in the sidebar. Virtual reality is now popular, and technicians and researchers are collecting large amounts of data to see how people react to the media in a more immersive environment.
