Digital aids for an aging society

As a result of 20th-century advances in medicine and standard of living there is a dramatic increase in the number of older people in the U.S. and most developed countries of world. Currently, people aged 65 years and older represent approximately 13% of the population and this number is expected to increase to 22% by 2030. Moreover, the fastest-growing subgroup within the older cohort is the "oldest old" (85 years and older) [4].
