“Reduce the risk
of navigation errors.”

"Reduce reaction time
and mental exertion."

How it works

Most (vehicle) navigation systems are based on step-by-step navigation. The user selects a destination and the system calculates a route. Navigation systems inform the user to take a left, take a certain exit or provide other navigation instructions. These systems provide information through a screen and speech. In our system, the user receives navigation signals through vibrations in the driver’s seat. Distinctive, intuitive patterns are pre-set to properly distinguish the navigation instructions.

The system of Sentaz is linked to third-party software. In case of vehicle navigation, this can be software like CityGIS, TomTom, Garmin, Falck or Sygic.

Pre-warning and warning

The Tactile Navigation gives two instructions: a pre-warning* and a warning when the exit needs to be taken. The timing of the vibration signals depends on the speed of the vehicle.

*The pre-warning is skipped if the subsequent warning signal needs to be given too shortly afterwards.

Keep left / right

» Single vibration on left/right

Turn left / right

Gif take the turn

» Single vibration on left/right.
» Double vibration on left/right.
» 2 x three vibrations on left/right.


Gif roundabout

» All vibrators vibrate consecutively in a circular pattern, starting at the back right side to the front side to the back left side.
» After that, the right vibrators vibrate a few times, corresponding with the number of the exit on the roundabout.

Turning back

» Single vibration on rear vibrators.
» Double vibration on rear vibrators (depending on the distance).
» 2 x three vibrations on rear vibrators.

Arrived at destination

» Simultaneous, long vibration on all vibrators.
