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.
