In Japan, the number of people with visual impairment including low vision was estimated to be 1.64 million as of 2007, and the number is forecast to increase to nearly 2 million by 2030.
Honda’s new business creation program, Ashirase is a wearable navigation system that assists visually impaired individuals with walking. The Ashirase is a navigation system consisting of a smartphone app and a three-dimensional vibration device including a motion sensor, which is attached inside the shoe.
How does it work?
Based on the route set with the app, the device vibrates to provide navigation. When the user should go straight, the vibrator positioned on the front part of the foot vibrates, and when the user is approaching a right or left turn, the vibrator on the right or left side vibrates to notify the user. The navigation provided by Ashirase enables intuitive understanding of the route, and therefore the user does not have to be constantly mindful of the direction, which makes it possible for the user to walk more safely and with a more relaxed state of mind.
What are some of the key features of Ashirase?
Guidance information for the visually impaired user is generated based on GNSS (Global Navigation Satellite System) positioning information and data based on the user’s foot movement.
Navigation is provided through vibration on the foot, so as not to interfere with the user’s hand which is holding a white cane, or ears used to listen to ambient sounds.
Vibrators are located aligned with the nerve layer of the foot, making it easy to feel the vibration.
Soft material that maintains its original shape is used for the device in order to limit any discomfort to the user.
When will Ashirase be available?
Ashirase, Inc. is currently developing an in-shoe navigation system to support the visually impaired with walking and will strive to begin sales of the system, also named “Ashirase,” before the end of the fiscal year ending March 31, 2023.
