Smart shoes to guide the blind?

These smart buzzing shoes could yet be among the most useful pieces of wearable technology for the visually impaired.

Designed by Indian wearable tech startup Ducere Tech, the "Lechal" smart shoes connect with a smartphone app via Bluetooth and buzz the wearer on which direction to go.

A video posted by the startup on YouTube also indicated the smart shoes could be for fitness buffs as well.

The lechal.com site said the shoes include Bluetooth-enabled insoles with sizes from 6 to 14 (US) and a universal USB charger that charges the pods.

Insoles have an anti-bacterial coating and are made of high-qualify polyurethene.

A separate article on tech site Mashable said a user can enter his or her destination into the Lechal app using a navigation app such as Google Maps.

"From this point on, the company claims, she no longer needs to look at her phone. The app connects via Bluetooth to a module that slides into the back of the shoe. The right or left shoe then buzzes depending on which direction the user should turn," it said.

Mashable also said the device's developers, Krispian Lawrence and Anirudh Sharm, pointed out the shoe was aimed as an improvement to the walking and navigation aids for the blind.

But the shoes are also for fitness buffs as well, as they work with an app to track how many calories the wearer has burned.

The shoes can sell for $100 to $150, which includes the footwear, the app and a charger. Versions of the app can run on Google's Android, Apple's iOS and Microsoft's Windows. — Joel Locsin /LBG, GMA News
