NEW YORK (AP) — Fitness trackers routinely measure physical activity such as running and cycling and encourage people to stand up and walk around throughout the day. But if you’re in a wheelchair, you’re out of luck.

Apple wants to change that with an upcoming Apple Watch feature announced Monday.

Instead of standing breaks, people in wheelchairs will be prompted to wheel or spin their chairs around regularly. Apple will also start tracking distance, speed and calories burned during wheelchair use, just as it does for walking or running.

The efforts could give Apple’s smartwatch an image boost over stand-alone fitness trackers such as Fitbit, though the target market isn’t likely large enough to significantly lift sales.

In the first three months of the year, three Fitbits shipped worldwide for every Apple Watch, according to research group IDC. Apple hasn’t released sales figures for its watch.

Jeff Williams, Apple’s chief operating officer, said the feature isn’t about market opportunities.

“We want to make products that serve every walk of life,” Williams said in an interview. “We realize that while it was great for messages on the wrist, we wanted to offer this group of people the same opportunity to get healthier using Apple Watch.”

Apple partnered with two groups that promote physical fitness in disability populations, the Lakeshore Foundation of Birmingham, Ala., and the Challenged Athletes Foundation of San Diego, Calif. The two groups recruited about 300 people in wheelchairs for more than 3,000 hours of activity research.

Jeff Underwood, Lakeshore’s president and CEO, said wheelchair users tend to be more sedentary than the general population because they face more barriers to physical activity. Although having a fitness device alone won’t make someone fit, he said, having one sends a message that inactivity shouldn’t be the norm.

The feature is part of a free software update, watchOS 3.0, expected later this year.

No new hardware is required.
