Consumer Characteristics

Consumer-app users have different characteristics than users of desktop systems. Consumers are familiar with appliances that typically have simple, predictable UIs, such as phones, microwave ovens, and remote controls, and might feel uncomfortable dealing with anything they consider too "high-tech." They expect consumer products to be predictable, easy to learn, and easy to use. While electronic appliances are common today, widespread acceptance of new products is still hard fought. Eight of ten consumer products fail in the marketplace, often because consumers find them too difficult to use.
