-To be done!
+**WORK IN PROGRESS**
 
 
 ## Aim
+The objective is to address two key questions:
+1. How many head marks are required to accurately localise the sensor positions relative to the head?
+2. Does the placement of these marks affect accuracy - for example, should they be distributed across the head?
+
 
 ## Methods
 
-## Results
+* Dummy model
+* Digitising helmet fiducials -> used to calculate "ground truth" sensor positions -> likely still some errors here due to Polhemus system not being 100 % accurate
+* Comparing "ground truth" sensor positions with positions estimated using marks (different numbers and different positions)
+
