1.1.3 Embedded Systems in Leisure Activities
At home, at work, even at play, embedded systems are flourishing. A child’s toy unexpectedly springs to life with unabashed liveliness. Automobiles equipped with in-car navigation systems transport people to destinations safely and efficiently. Listening to favorite tunes with anytime-anywhere freedom is readily achievable, thanks to embedded systems buried deep within sophisticated portable music players, as shown in Figure 1.3.

Even the portable computing device, called a web tablet, shown in Figure 1.4, is an embedded system.

Embedded systems also have teamed with other technologies to deliver benefits to the traditionally low-tech world. GPS technology, for example, uses satellites to pinpoint locations to centimeter-level accuracy, which allows hikers, cyclists, and other outdoor enthusiasts to use GPS handheld devices to enjoy vast spaces without getting lost. Even fishermen use GPS devices to store the locations of their favorite fishing holes.
Embedded systems also have taken traditional radio-controlled airplanes, racecars, and boats to new heights…and speeds. As complex embedded systems in disguise, these devices take command inputs from joysticks and pass them wirelessly to the device’s receiver, enabling the model airplane, racecar, or boat to engage in speedy and complex maneuvers. In fact, the introduction of embedded technology has rendered these sports safer and more enjoyable for model owners by virtually eliminating the once-common threat of crashing due to signal interference.
