ABSTRACT
Maximizing the Usefulness and Usability of Healthcare Technologies As individuals age, they are likely to experience loss of visual acuity and some hearing loss, as well as reduced cognitive capacities such as declines in working memory and attention (see Chapters 2 and 4 for more details). Changes in touch sensitivity and movement control are also common. In addition, older adults often have at least one chronic condition, such as hypertension, arthritis, or diabetes (see Figure 9.1), and many have multiple chronic conditions. Many women and men over the age of 65 are also caregivers — caring for a spouse or an older relative.
