Older adults will accept monitoring technology to live in their homes longer

May 06, 2004

Younger adults might cringe at the thought of being monitored in their homes by technology. Yet a new study from the Georgia Institute of Technology indicates that older adults are willing to give up some privacy -- if it enables them to remain independent longer.

"That illustrates how important it is to older adults to stay in their homes rather than move into some type of assisted-living housing," said Wendy Rogers, a professor of psychology at Georgia Tech. Rogers presented preliminary findings of the study at CHI2004, an international conference on computer-human interaction held April 24-29 in Vienna, Austria.

The study, which examined older adults' perception of a technology-rich home environment, was part of the multidisciplinary Aware Home project conducted at Georgia Tech's Broadband Institute Residential Laboratory. The laboratory, funded in part by the Georgia Research Alliance, is a unique three-story house where researchers focus on domestic technologies for the future. The study Rogers presented was funded by the National Science Foundation and the National Institutes of Health.

For this study, researchers invited 44 adults ages 65 to 75 to tour the residential laboratory and view new technologies designed by Georgia Tech College of Computing researchers specifically to help people age in place. These technologies, ranging from low to high levels of intrusiveness, included: Researchers asked participants what they specifically liked and disliked about the technologies. To spark qualitative responses, all questions were subjective in nature, such as: What is your first impression about living in a home like this? How would you feel about living here? Do you think there may be situations in which an Aware Home could invade your privacy?

The interviews with older adults were audio-taped and transcribed verbatim. Researchers then created a coding scheme and analyzed comments along different dimensions, such as attitude to technology and context of use.

"Understanding how older adults evaluate technology provides insights into their judgments and decision-making processes, which will help us design tools they will actually use," Rogers said. "Technology in the home is useless if people don't want it."

Unlike younger adults, older people don't care if a technology is the latest thing or a status symbol. Instead, what sparked interest among study participants was the degree to which a particular technology could benefit them.

Another key factor was whether they viewed the technology as a luxury or necessity. "They were more willing to embrace a technology if they perceived a need and if they had some degree of control," Rogers said.

Critics might consider the Digital Family Portrait as a privacy invasion because it monitors residents and transmits that information to someone else. "For younger adults, there would be no trade-off," Rogers said. "Yet some of the older adults who participated in the study said they actually felt more secure if someone was monitoring them."

FaceBot sparked the most divergent comments. Some participants liked it, while others were uncomfortable with the aesthetics of the face, deeming it "creepy."

Participants also envisioned new uses for the technologies. For example, one individual liked the idea of using FaceBot as a robotic butler of sorts to welcome guests into the home. Another person suggested Cook's Collage could be used as a memory aid when taking medications.

The study drew from an ethnically diverse pool, including Hispanics, non-Hispanic whites and blacks. Researchers were curious if cultural differences might affect older adults' evaluation, but none appeared in the initial analysis, Rogers noted.
