Fig. 3: Scratch power labeling using a pressure-sensitive tablet.
From: A multimodal sensing ring for quantification of scratch intensity
The pressure-sensitive tablet outputs force, x-position, and y-position over time for each contact. This data is fed through our force and velocity algorithms to calculate average force and average velocity for each sample of data. Power is subsequently calculated by multiplying average force and velocity. Permission was obtained from Sensel Inc. for use of the Sensel Morph image.
