[0001] Wearable information providing device for blind [

The present invention relates to an information providing apparatus for a visually impaired person, and more particularly, to an information providing apparatus for a visually impaired person, in order to solve the inconvenience of an existing visually impaired person who simply had to rely on a cane or a guide dog, The present invention relates to a wearable information providing device for a visually impaired person.

In addition, in order to solve the inconvenience of the existing visually impaired persons who simply have to rely on a cane or a guide dog as described above, in addition to providing information on the surrounding environment to the visually impaired person, A wearable information providing device for a visually impaired person which is constructed in the form of a wearable device that can be worn by a user as shown in FIG. 1, is configured to be easily and easily usable without having to carry a separate device separately, .

According to statistics on the current status of disabled people surveyed by the Ministry of Health and Welfare in December 2014, 2,276,910 people with disabilities among the total population of Korea accounted for 5.59% of the total population.

Here, the incidence rate of visually handicapped persons in Korea is 6.34 cases per 1,000 people, which is about 0.63%. The total number of visually impaired people is estimated to be about 310,000, and the rate of increase of blind people is 0.35%. Recently, Despite the decrease in the overall incidence of persons with disabilities as a result of development, the incidence of blind persons has increased significantly.

In addition, in the case of visual impairment, the incidence of acquired disability is stronger than that of the pre-emptive disorder. As the age increases, the incidence increases, and the number of the visually impaired is increasing every year without decreasing, The daily life of the people requires the social consideration and concern of the general public.

More specifically, in general, a visually impaired person must carry a white cane indicating that he or she is visually impaired when going out, but in the case of the general public, they often do not know exactly what this means. For example, it is difficult to determine when to cross a cane because it is impossible to see a signal when walking on a pedestrian crossing, and it is difficult to detect whether there is an obstacle in the upper part of the cane. Is always present.

Moreover, even if a blind guide dog is accompanied by a guide dog for guiding the road, there is a concern that the blind guide dog may inconvenience or dislike the blind guide dog. Therefore, the cane and the blind guide dog are very inconvenient and dangerous for the blind Recently, in order to solve the inconvenience of the visually impaired, various researches have been conducted on the information providing device which provides various information such as guidance on the walking of the visually impaired persons.

Here, as an example of the prior art related to the information providing apparatus for a visually impaired person as described above, for example, according to Korean Patent Registration No. 10-1583752, a plurality of devices are installed at various positions, A voice induction unit installed in the frequency band for receiving and transmitting the GIS position information; a user terminal for receiving the non-audible voice transmitted from the voice induction unit and outputting GIS location information in voice or text, The GIS location information of the voice inducer is outputted as a voice or a letter from the user terminal to confirm the GIS information of the current location, and the user terminal transmits the non-audible voice frequency transmitted from the voice inducer to the voice or text The smart phone is a smart phone in which a web for outputting characters is executed in advance. When the navigation is performed, the GIS location information is received, and a program for comparing the location of each voice inducer with the position of the navigation and outputting the voice information is installed to check whether the visually impaired person moves to a desired place. The technical contents of the providing system have been presented.

As described above, another example of the prior art relating to an information providing apparatus for a visually impaired person is disclosed in Korean Patent Registration No. 10-1400828, for example, in which a body having a bar shape and a body A cane having a handle formed to be catchable by a user; A sensor unit installed on the cane and collecting information on the movement path of the user; A power unit installed on the cane to supply power to the sensor unit; And a smart terminal for receiving information on the movement path of the user collected from the sensor unit and transmitting the information to the user by voice. The sensor unit may include a camera for photographing a movement path of a user; A direction sensor for confirming the current traveling direction of the user in real time; An ultrasonic distance sensor for measuring a time when a sound wave bounces against an object in a moving direction of the user and returning the measured value as a distance; A vibration motor for informing the user of the distance to the object when the ultrasonic distance sensor detects the object; A communication module for transmitting information on the movement path of the user collected through the camera, the direction sensor, and the ultrasonic distance sensor to the smart terminal; A pulse sensor installed on the handle of the staff to measure the pulse of the user; And a power source is supplied when a pulse of a user is sensed through the pulse sensor.

In addition, according to another example of the prior art relating to an information providing apparatus for a visually impaired person as described above, for example, Korean Patent Registration No. 10-1164183 discloses a bar-shaped main body carried by a visually impaired person; A GPS unit for extracting coordinate information of a local point; a memory unit for storing position information and path information for each coordinate information; an input unit for inputting a destination point; an output unit for guiding path information between a local point and a destination point; And a path guide module configured to include a control unit for controlling the driving of the visually impaired person, wherein the main body is provided with a plurality of lasers for forming a light region by irradiating a laser beam in each traveling direction, The lamp is installed in a radiation structure and the control unit is configured to form a light region in front of the traveling direction by turning on the corresponding laser lamp for irradiating the laser beam in the traveling direction of the path information guided through the output unit among the plurality of laser lamps The present invention relates to a traveling route guidance apparatus for a visually impaired person.

Furthermore, as another example of the prior art related to the information providing apparatus for the visually impaired, as described above, for example, in Korean Patent Registration No. 10-1309475, a cane body; A rotatable rotary shaft provided at a stationary portion and a stationary portion formed at a lower end portion of the cane body; A secondary stick fixed to the rotary shaft; Rotation preventing means for preventing the auxiliary stick from being rotated and spreading from 100 degrees to 130 degrees or more; The auxiliary stick is capable of being walked while tapping the ground with the cane in a state in which the auxiliary stick is deployed at an angle between 100 and 130 degrees, A technique for a visually impaired person who can walk while pushing a stick to the ground in a state where the auxiliary stick is deployed at an angle of 100 degrees to 130 degrees or in which the auxiliary stick is partially folded is presented.

As described above, various technical contents have been presented to the information providing apparatus for the visually impaired, but the above-mentioned apparatus and methods of the related art have the following problems.
