Can someone test this app and report its usage? I no longer have the iOS
device so this request.
OVERVIEW
Clew is a path retracing app designed for blind and visually impaired
users to help them independently return to any desired locations.
Using Apple's new ARKit built for iOS 11 devices, Clew records a path
and guides the user back to their starting location with a choice of
voice directions, sound effects, and haptic feedback. FEATURES
HOW IT WORKS
Augmented reality, exemplified by Apple's ARKit, superimposes virtual
elements onto the real world. In this case, we add virtual "keypoints"
to navigate you through unknown areas.
What it does
• As you walk to a location, your phone keeps track of its path with a
series of virtual crumbs.
• After you get there, your phone simplifies the path to a series of
"keypoints" where you made a turn or used a stairway.
• As you navigate back, your phone will give you instructions to each
point, in reverse order, until you reach your starting location again.
• You're now back at your seat, classroom, or restaurant table. Enjoy
yourself
FREQUENTLY ASKED QUESTIONS
What is Clew?
Clew is an indoor, path tracing navigation app built for blind and
visually impaired users. It is designed to remember a location like a
seat or a room and assist you to return to that destination after
exploring your surrounding environment.
How can I get Clew?
Clew is available for free on the App Store and is compatible with
iPhone 6s and newer models running iOS11. For the full haptic
experience, iPhone 7 and newer is recommended.
What’s the best way to use Clew?
To ensure that the camera is fully capturing your surroundings, hold the
phone in a vertical portrait position with the camera facing away from
you while you use Clew. Also, make sure the camera is fairly stable to
ensure accurate location tracking.
In what environment does Clew work best?
Clew works best in well lit areas with distinct visual features and few
moving objects like crowds and cars. Although Clew can be used outdoors,
it is not as accurate in open areas and intense sunlight. Clew works
optimally indoors over relatively short distances.
What is the pause feature?
You can pause Clew once you arrive at your destination and before you
start navigating back. Press the pause button on the bottom right corner
and follow the instructions. Once Clew is paused, you can exit the app
to do other tasks or lock the phone as long as you don’t shut down Clew
from the app switcher. When you are ready to return, press the resume
button and follow the instructions to start tracking.
How can I report a problem?
Please use Clew at your own discretion. Clew's ability to track your
movement through a space can be affected by many factors (lighting
conditions, the orientation at which you hold your phone, etc.), and
therefore may not function correctly all the time. Help us improve the
system by rating your routes as good or bad. Bad routes will examined to
further refine the app. If you'd like to offer additional feedback, the
easiest way to do so is to e-mail the Clew team.
