Indian Techies Develop LeChal, World’s First Interactive Haptic Footwear


Mobile Devices have changed the way we live our lives, but it looks like wearable technologies are going to take it one step forward. I am sure you have already heard fascinating stories of wearable gadgets like Google Glass.

Now, two Indian techies have come up with something that is not only innovative but a little surprising as well. They have developed LeChal (pronounced lay-ch-al, meaning “take me there” in Hindi). Krispian Lawrence and Anirudh Sharma, founders of Ducere Technologies are the brains behind LeChal, world’s first interactive haptic based footwear.

LeChal Interactive Haptic Footwear

LeChal was first designed to help visually impaired with mobility through unobtrusive means; the duo soon realized that this innovation can be useful for everyone. This thought was further developed to launch stylish footwear with interactive haptic based navigational system guiding the user towards their destination through simple vibrations in the footwear.

How Does LeChal Work?

LeChal offers a completely hands-free experience in areas of navigation and fitness with a combination of footwear (insoles or shoes) and an smartphone app. Here is how it works.


An app loaded on a smartphone pairs with the footwear via Bluetooth. The user interacts with the app and can set a destination. The phone’s GPS is used to calculate location data and the directions are conveyed to the user via haptics (simple vibrations) in the footwear. The footwear that vibrates is the way to go.


‘LECHAL’ footwear counts your steps, and tracks your calories burnt. Through the App the user can set goals, create custom workout sessions and much more.


‘LeChal’ footwear allows you to tag locations, set destinations, start/stop/pause navigation and much more, all by executing simple foot gestures.
