Values

Collected values are stored in dictionaries.

Each contact has the following elements stored. Ranges are normalised (vals.c) or raw (deviceVals.c, in sensels or gram).

The avg has the following elements stored. Ranges are normalised (vals.avg) or raw (deviceVals.avg, in sensels or gram).

Below you can see how the different parametes affect each other. Shown are: positions and force of two contacts, their average position and force (contantly in-between), and their weighted average position and force (moving from one to the other while force is altered).
