Modern technologies have made a huge impact on most man-made things used in everyday life. From small objects, such as flashlights, hand-held terminals, battery operated toothbrushes and power drills to relatively large objects such as washing machines, dish washers, motor cycles, and cars. Digital technologies are everywhere ? computers, wireless communication devices, personal digital assistants, MP3 players, CD, DVD, to name a few. It is important for design students to understand the principles of these technologies to better understand how man-made things are designed; to consider how objects are used and to predict how things will be used and what kind of designs are expected in the future. The class will present an overview of those technologies in order to give students a clear understanding of how they can incorporate the technologies into their design practice.
