New smartphone app developed at USC aims to support fitness among older adults

Picture
​If the infomercials are to be believed, older adults want cellphones that are anything but smart. With oversized displays and one-touch medical alert buttons, products like the Jitterbug flip phone are simple by design.But technology usage trends among seniors are changing faster than ever. According to the Pew Research Center, 42 percent of Americans aged 65-and-older own a smartphone. As the digital gap between generations narrows, USC researchers hope to harness the potential of smartphone apps to improve the lives of older Americans.
“We’re looking at a wonderful opportunity for utilizing mobile devices to promote wellness and prevent disease,” said Stacey Schepens Niemiec, assistant professor of research at the USC Chan Division of Occupational Science and Occupational Therapy.
That opportunity will soon be made a reality. Thanks to a new $468,000 grant from the National Institute on Aging, Schepens Niemiec and her team of health professionals, engineers and community partners will systematically develop and test MovingUp, a multi-feature smartphone app designed to facilitate older adults’ levels of physical activity.
