Traditionally, consumers use mechanical buttons, knobs, dials, sliders and switches to adjust time, temperature and other settings on household appliances. However, engineers have been experimenting with a wide variety of touch-sensitive interface technologies that make appliances easier to use and more aesthetically pleasing to look at. The new displays and controls found in refrigerators, dishwashers, ovens, microwaves, coffee makers, washing machines and other products are inspired by the consumer electronics industry.
