Waymap app helps the visually impaired navigate public transport
in London Route map needs to assist visually impaired individuals navigate their environment, and that begins with public transportation. The firm simply accomplished a closed two-week trial of its navigation app at three Washington, D.C. subway stops and hopes to start an open trial at 25 subway stations and 1,000 bus stops by September, in keeping with Waymap.

“We learned from our trial that this is so important for blind people because when you lose your sight, you lose the freedom to explore,” Waymap CEO and founder Tom Pei, who based the corporate after dropping his sight at age 39 . previous, Thealike advised.

“A typical blind person regularly uses about 2.5 routes. And that means they can go to the grocery store and the pharmacy. And the reason for this is the amount of information that you have to remember when you lose your sight, and packing it all in your head is quite difficult, as well as trying to protect yourself using your basic mobility. So what we’re doing is replacing human memory and giving the human access to infinite memory in terms of routing, and that allows him with his mobility skills to go anywhere.”
Traveling wherever is, in fact, a long-term aim as the corporate grows, however within the quick time period, Waymap begins with public transportation after which expands to locations like museums, inns, hospitals, or different public buildings. The firm has piloted its expertise around the globe, however Washington, D.C. would be the first whole metropolis to deploy the app.

The Waymap app offers free audio step-by-step directions for customers, guiding them to inside 3 toes. And Waymap actually means it when it says “step by step” as a result of the startup doesn’t use GPS to trace customers; it connects to the smartphone’s inertial measurement unit sensors—magnetometers, accelerometers, and barometers—to get knowledge equivalent to how briskly somebody walks, how they stroll, whether or not they go up or down stairs. This knowledge is then fed right into a proprietary Waymap algorithm that depends on Bayesian statistics to extract 5,000 attainable positions the consumer could be in primarily based on their subsequent transfer and decide the place, primarily based on the chance, they’re more likely to be. This algorithm is run along side Waymap’s “map-matching” algorithm to offer exact directions to customers.
Someone utilizing the app would possibly hear one thing like:
“Turn 10 o’clock, then walk forward four steps. Turn 2 o’clock for the pedestrian crossing. After the pedestrian crossing, continue straight ahead. After 10 steps, turn for 1 hour. Turn 1 o’clock in nine steps. Follow the path…”
For the most recent take a look at in DC, 15 visually impaired Waymap customers, seven sighted customers, and three orienteering and mobility instructors connected their telephones to their waist holsters.
“Our algorithm records the kinetic energy you use to walk, and this allows us to understand the approximate speed at which you are walking and the likely length of your stride,” Pei stated, noting that the app first captures the consumer’s location utilizing GPS and even “ non-location” such because the consumer’s entrance door, till then relying solely on sensors to find out the place the consumer is in relation to their surroundings.
“Once we know the speed or stride length and know where you are, the algorithm determines with 99.999% accuracy where your next step will be,” continued Pei. “If you change the speed, we will detect it because this energy is going through your hip. So we are 99.999% sure where you are.”
Obtaining an correct location additionally is dependent upon environmental mapping. As Waymap scales, it’ll use maps of native transit authorities or open road maps when displaying the exteriors of public transit stops and stations. However, for the Washington take a look at, Waymap used lidar scanning to map the stations, in addition to 360-degree video. The scans offered a fundamental structure of the stations, and the video helped establish obstacles or factors of curiosity equivalent to poles, trash cans or seating for individuals with disabilities.
In the longer term, when Waymap utilization reaches crucial mass, Pei needs to encourage sighted individuals to make use of the app whereas touring in order that they’ll successfully feed the startup knowledge about their steps and the way they navigate positions. This will assist Waymap algorithms study from always up to date maps and route data.
Waymap just lately closed a $4.9 million (£4 million) pre-Series A and plans to extend its Series A subsequent yr. Pei stated the funds shall be used to proceed growing the expertise in all areas of localization and mapping, in addition to constructing a startup enterprise improvement group within the US.
Pei expects Waymap, which is already worthwhile from transportation authorities and cities, to grow to be worthwhile quickly after its subsequent enhance.
