Design is about exploring, visualizing, creating and demonstrating innovative concepts and experiences using appropriate technologies. To design interactive systems and building prototypes, designers choose and integrate appropriate sensors and actuators, use object-oriented design, algorithms, circuits and mechanisms. They can communicate with engineers from different disciplines (e.g. Electrical Engineering, Computer Science, Mechanical Engineering) and understand their scientific writings. They can read specifications and datasheets, and they can document hardware and software conscientiously. They can make informed judgements through calculations and appropriate mathematical tools to demonstrate the technical and economic feasibility of their designs. They have an awareness of data science and artificial intelligence.
