In addition to providing a means to discuss our own senses, working
with sensors requires knowledge of traditional mathematical operations.
Techniques for averaging and thresholding are necessary for dealing
with almost all sensors. Following the pedagogy I laid out earlier, these
skills were encountered while "doing" - in real situations, rather than
constructed or artificial settings. These methods drew on the relevant
areas of robotics, control theory, and digital signal processing*. This
was all contextualized within the goal of making devices that were
personally meaningful to the creator.
