A tactile navigation system for blind people

摘要

The present invention relates to a road guide system for blind people and more specifically, a road guide system for blind people which comprises: a mobile communication terminal having a dedicated application installed therein to guide a road for blind people; and a stick connected to the mobile communication terminal through a wireless communication and helping walking of blind people. According to the present invention, a compass sensor is provided in a stick and a direction indicating pin is provided at a handle part at the outside of the stick. Accordingly, when a user enters a destination with voice by executing a road guide application installed in the mobile communication terminal, the road guide system for blind people calculates a route according to destinations by grasping the location of a user through a GPS sensor of the mobile communication terminal, calculates a front direction of the user grasped by receiving the direction in which the stick faces from the compass sensor of the stick and a progress direction of a route according to destinations through the current location and destination location of the user measured through the GPS sensor, and intuitively induces a progress direction through a body part of the user in contact with the direction indicating pin as a command is transmitted to rotate the direction indicating pin included in the handle part of the stick according to the direction of progress. Therefore, the road guide system for blind people is able to accurately deliver, through tactile sensation, even a narrow angle difficult to be measured only by a voice guide, thereby being able to effectively increase the accuracy of the progress direction of a user when guiding a route.
