Sensor Technologies for Interactive Environments
MIT OpenCourseWare offers this advanced electrical engineering course covering sensor technologies used in human-computer interfaces and ubiquitous computing. Lectures start with electronics for sensor signal conditioning, then move through sensor architectures for pressure, strain, displacement, proximity, thermal, electric and magnetic field, optical, acoustic, RF, inertial, and bioelectric modalities. The course also covers basic sensor processing algorithms and wired and wireless network standards. Materials include lecture notes, written assignments, a set of hands-on laboratories, and a final project applying the sensing techniques to a working device. As with other MIT OCW offerings, all materials are free to access under a Creative Commons license, with no certificate offered. The course suits students building physical computing or interactive systems who need a grounding in how real-world signals get captured and converted into usable data.
