Compare two methods of analyzing human intent in steering a passive walker

A passive walker with two different sensor settings on its handle has been installed and tested. Quantified data from different sensors were collected and then used to establish a corresponding relationship to the human intent. In this paper we try to compare two methods, one is based on 6-axis force/torque sensor, the other is pressure sensors. Preliminary result shows that a passive walker with low cost pressure sensors can still provide human intent assessment as well as the one with high price force/torque sensor.
