abstract
This letter describes system architecture for a navigation tool for blind people. The main parts are: a multi-sensory system (including stereo vision, acoustic range detection and movement sensor), a mapper, a warning system, and a tactile man-machine interface. The sensory parts have been described in more detail, and earlier experimental results have been presented.
an objective:
Approximately 1% of the human population is visually, and about 10% of them are completely blind. One of the consequences of blindness is the limitations in mobility. For global navigation, many devices are already present, for example, in external conditions, Handheld GPS systems are now available for blinds These devices are not useful for local navigation: Researchers from traditional path planning and collision are the traditional equipment, i.e. Thank you Ed dog and cane tools, but these tools do not address adequately the local navigation problems. Guide dogs are not working on a large scale (the training capacity in the Netherlands is about 100 guide dogs annually, enough to help just about 1000 users) The cane is very restrictive
The goal of this research is to develop a wearable device that helps the blind complete its local navigation work. Figure 1 shows the architecture of the proposed device that contains a user-controlled sensory system. The primary data limit data required for local navigation (which is not necessarily derived from the visible data; At this time, the type of sensor is still an open question) Changes the range data in map map data Local map There is input for a warning system which converts the map data into a form that is suitable for communication. To give the blind person the freedom of movement, he should be able to focus on focusing on the sensory system. For that purpose, the device must be provided with a man-machine interface.
The final goal of this project is to provide an electronic device for the blind's local navigation work. To provide information about the direct environment of the blind, this device should be able to rotate without collisions. We believe that, although mostly unknown, there is some structure of the environment in urban outer conditions (for example a road), or in an indoor situation: smooth floors, now and then one door, stairs, walls, doors open and all objects Like those who probably stop the route.
