Abstract: The present invention provides portable navigation systems, devices, methods and software for provision of navigation indications to a user in a GPS-denied environment, the system including at least one portable device, including a navigation Application (App) adapted to provide the user with navigational instructions and at least one interface component to provide at least one direction-specific instruction of movement to the user, wherein the App comprises an embedded algorithm adapted to fragment a continuous line course on a map associated with a two or three-dimensional route, the algorithm constructed to provide instructions to the user, responsive to a current position of the device associated with the route, wherein the at least one device is adapted to provide commands from the algorithm to activate the at least one vibrational components, responsive to a position of the device.

Abstract: The present invention provides methods, systems and a device for provision of a tactile language comprising a set of distinguishable tactile instructions to a user, the method including providing the language comprising the plurality of combinations of tactile stimuli, wherein the device is configured to provide unmistakable, distinguished commands, without the need for verbal or visual instructions and wirelessly communicating instructions to the device to activate at least four tactile stimulus components of the device thereby providing the set of distinguishable tactile instructions to the user, wherein the instructions are selected from real instructions and virtual reality instructions and combinations thereof.

Abstract: The present invention provides a wearable navigation forearm-band device for intuitive navigation of a user to his destination, the device including at least four tactile stimulus providers, each adapted to impact on different areas of a forearm of a user to provide a specific direction of movement of the user, wherein the device is adapted to receive commands from a communication apparatus to activate said vibration indicators response to a position of the user.

Abstract: The present invention provides a method for provision of a set of distinguishable tactile instructions to a user. The method includes providing a plurality of tactile stimuli to the user from a device, each of the tactile stimuli combination providing only one instruction of the set to the user. The device is configured to provide unmistakable, distinguished commands, without the need for verbal or visual instructions. The method also includes wirelessly communicating instructions to the device to activate at least four tactile stimulus components of the device thereby providing the set of distinguishable tactile instructions to the user.
