Introducing Ducere Technologies' Lechal shoes that have Bluetooth-connected haptic modules. More specifically, its a vibrating insole Interfacing with a smartphone via Bluetooth. These smart insoles could have any number of applications like runners and the visually or audibly impaired. It vibrates to let them know where to turn when they’re out jogging or walking and may even help the vision-impaired get around. But not only for them as this technology could also apply to a driver, racer and motorbike rider where a pulse could prompt them to change gears, turn, or an extended vibration warning of imminent danger. It could even include drowsy driving, lane departure warning, anything that requires a beep or flash to get an immediate reaction.
The only limit would be how to interpret the different vibrations, but the possibilities are virtually endless, especially when combined with the vibrating seats now being produced by the likes of General Motors and Mercedes-Benz that warn you if one is veering out of lane and such. They could, in theory, even extend navigational guidance to show how one could get from their car to their specific destination and guide them back.
