The just-published AARP study of 50+ consumers and design of sleep and activity trackers has found that a near-or majority surveyed found activity and sleep trackers useful in maintaining health. 71 percent found they increased awareness of habits; 67 percent found them useful and beneficial. Four user personas emerged: sticklers, achievers, enthusiasts and the ‘why not’-ers. Yet these mostly enthusiastic users experienced difficulties. During the six-week trial, many discontinued use of the trackers due to data inaccuracy, finding and using instructions, perceived device malfunctions, difficulty in syncing, difficulty in putting on the device and comfort in wearing. The seven trackers used by the 92 participants were from Misfit, Spire, Jawbone, Lumo and Withings. Conducted by Georgia Tech Research Institute’s HomeLab with AARP’s Project Catalyst: The Power of We initiative which encourages good product and service design for the 50+ demographic.
