ABSTRACT
Movement An idea or desire is translated into a series of movements to become an action. For example, movement is almost always the way that we externalize thought-by whole body movements, making hand gestures or facial expressions, or vibrating our vocal chords. It is only in recent years with the ability to visualize brain activity and use brain activity to control computers that we have gained the ability to externalize thought without human movement. It is fortunate that for most activities movement is preserved well into old age, unless there is pathological disease. It may become harder to use small implements or to quickly react, but for the most part people move with few adverse effects. Technology, however, can become a stumbling block to movement performance for older adults, because many displays and interfaces require fine movements, and the consequences of an error are time-consuming and frustrating. One example is the small PDA or cell phone. A stereotype exists that older people are not as interested in these technologies as the young or that they are unwilling to learn to use them. This stereotype does not take into account the increase in initial frustration levels for someone who touches the wrong icon and has to solve what went wrong and how to fix it.
