Is the human a measurement instrument?

Research Project "Geodesy meets Neuroscience"

Brain TLS

Perceived Space Representation using Brain Activity Analysis, Eye-Tracking and Terrestrial Laser Scanning

Is the human a measurement instrument?

Within this project, we consider that the brain activity and eye movement analysis of a person in combination with a space-calibration method can be used to represent the perceived space. 

Humans describe reality with the help of veridical perception and pre-knowledge. Nowadays, brain activity analysis may be done through non-invasive methods. Most studies in the field of neuroscience are related to extracting information after observing the state of the brain. Eye-Tracking, on the other side, is used to analyze fixations and saccades by recording pupil movements with external cameras. This can be done for a multitude of purposes, but this project focuses on the gaze positions in a defined area.  The question arises if the signals captured with a Brain Computer Interface (BCI) combined with eye-tracking information and corrected by an existing 3D model of the observed space can be used to create a digital representation of the same space.

Objective

The scale and geometry of the perceived space are firstly defined with the help of a 3D terrestrial laser scanner (TLS). The implied methods and experiments aim at establishing a connection between instrument-measured space and human-perceived space. Defining geometric relationships between the observer (person) - observed objects and finding a correlation of the geometric attributes with the brain activity and eye-tracking data are the main goals of this project. If these goals are achieved, an innovative measurement method may be developed and a better insight into how the human brain perceives the surrounding space may be gained.
