The CADANS Approach
Main Goal of CADANS
Development of a 3D statistical
anthropometric CAD-plugin for the
design of wearable products
The CADANS Approach
Based on an award winning proof of concept SW-plugin

Same electrode locations as EPOC
One size fits all
Fit for p1 to p99
Optimal stability during movement (maximal 5mm)
Maximal location error of 20mm
Repeatability (maximal 20mm)
Deadline 16days
o Optimized for 3D printing
o Unambiguous positioning on the head (by non experts)
o Not an ergonomically, usability or visual design, but a purely
mechanical prototype
