A portable navigation device and associated methods are provided for enabling users to find geospatial orientations within the real physical world using their tactile senses. In one embodiment the portable navigation device acts as a geospatial compass, enabling users to find cardinal directions such as North in response to processor controlled tactile feedback sensations provided with respect to geospatial orientation sensor readings. In another embodiment the portable navigation device acts as a geospatial trajectory assisting device, enabling users to find travel direction indicated by a preplanned route or map in response to processor controlled tactile feedback sensations provided with respect to geospatial orientation sensor readings. In this way a user may perform a manual scanning operation wherein they manipulate the portable navigation device through a range of physical orientations and find a desired geospatial target orientation based upon their sense of touch.
