Content, progress and pedagogy of the module

Objectives:

Physical Interface Design is a course module where students learn about basic principles of electronics and how different sensors can be interfaced to a microcontroller to design novel forms of interactions between man and machines.

Learning objectives

Knowledge

Students who complete the module will obtain the following qualifications:

• Should be able to recall basic circuit theory concepts and rules, including resistance, voltage, current, Ohm’s law, and Kirchoff’s laws (knowledge)
• Should be able to describe basic analog (e.g., potentiometers, force sensitive resistors) and digital (e.g., push button, touch interface) sensing technologies (knowledge)
• Should be able to express how a micro-controller can be used for measuring/actuating analog and digital inputs/outputs by the use of sensors and output devices (e.g., displays, LEDs, and vibrators) (understanding)
• Should be able to recall that some functionalities can be implemented using both hardware and software (knowledge), and to discuss the pros and cons of either solution (understanding)
• Should be able to identify practical needs in electric circuits such as DC filtering and circuit protection (understanding)
• Should be able to describe basic amplification (e.g., OpAmp) and filtering (e.g., RC and RL) circuits (knowledge)
• Should be able to explain basic concepts such as sampling and scaling in context of real-time use of signals (understanding)

Skills

Students who complete the module will obtain the following qualifications:

• Should be able to apply the taught skills and methods on physical interface design to develop a prototype/artifact, and to demonstrate its use (application)
• Should be able to formulate a linear system of equations for voltage, current and resistance relationships in an electric circuit, and to solve the system to find unknown currents, voltages, or resistances (application)
• Should be able to use an electronic circuit simulator (application)
• Should be able to sketch and interpret an electric circuit diagram (application)
• Should be able to program a microcontroller to make it read inputs from sensor circuits and produce output(s) to a user (e.g., vibration, light, and text) (application)
• Should be able to examine and verify basic electric circuit designs using, e.g., a multimeter, and to test if a build electric circuit has the desired functionalities (analysis)
• Should be able to apply basic interface design principles for realizing a physical interface for human-computer interaction in the context of use (application)
• Should be able to assess the artifact by applying taught evaluation method(s) (evaluation)
