The invention relates to a method for generating a data authentication key for allowing data communication over a wireless channel between a first mobile device and a second mobile device, comprising: associating said mobile devices to each other by means of said key. The invention comprises: allowing a shared physical or mechanical condition to be applied generally simultaneously upon said devices; detecting, in said first mobile device, said condition; defining, in said first mobile device, said authentication key based on the detected condition; and transmitting said key to said second mobile device. The invention also relates to a mobile device configured for generating a data authentication key for allowing data communication over a wireless channel to a further mobile device.

Method and mobile device for generating a data authentication key

The invention relates to a haptic navigation system, configured for providing a haptic instruction to a user, and to a method for providing a haptic instruction to a user. The haptic navigation system comprises a navigation module comprising a route calculation unit, configured for calculating at least one route for the user to go to a predetermined destination, and a user interaction unit, configured for capturing at least one input parameter from the user, and a feedback unit configured for receiving an instruction sent from the navigation module and for converting the instruction received into a haptic instruction such that the user find the correct route. In this way, a haptic navigation system is provided which is reliable, cost-effective to realize and can easily be integrated into existing navigation systems while at the same time making it possible to get rid of displays or voice recognition in navigation applications.
