  • Thus, the advantage of the present invention is Compared to the known approaches is that the user is affected by the signaling of the relevant hint information in haptic form neither in its acoustic perception nor in its visual perception, as can be dispensed with an acoustic and an optical transmission of information information.
  • Consequently For example, in a vehicle navigation system, the directional indications become transfer the user haptically in such a way that this neither in his interior communication nor at his acoustic perception of the traffic is disturbed. In addition, the motor vehicle user does not have to look at it associated display to the output information signals to be able to receive. Therefore, the vehicle user can keep his eyes focused on the traffic be addressed, so that the traffic safety is advantageously increased.
  • at Mobile navigation systems have another advantage that the hint information is also in noisy environment unlike acoustic indications are perceptible. In addition, the environment is also before a noise pollution protected by any acoustic signals, as an exchange of information not audible goes on. Furthermore the environment or the environment can transmit the transmitted warning signals not perceive, so that the privacy is guaranteed.
