The visually-impaired people face, perhaps, the harshest and most difficult situations having to live in a world they cannot see. From breakfast to traveling, they have to rely on others, unless they are well-familiar or adapted to the situations. If one creates something to even guide these people a couple of steps, he/she manages to earn love, gratitude, and respect from them.
The world is beautiful and colorful, but for a visually-impaired person, it is all black and dangerous. Every step requires care and safety. This is usually the case while traveling where these people have to encounter unknown situations that may lead to fatal accidents. However, with advancement in technology and arrival of GPS navigation, these people have got the support they very much needed in the GPS- tracking devices.
The target and the need
These GPS devices are especially made for those visually impaired people who have to travel to distant places, unknown zones, and difficult terrains. These people also face the gravest risks of their lives, such as road-accidents and stumbling. These devices help in overcoming such risks and also help people in places where a different language is used. There are cases when blind people get lost. In such a case, these systems help in tracking them down, as well as helping them remap their path.
If the above features are incorporated into the navigating device, the device can become an excellent aid to the visually-impaired people. Moreover, these devices are designed in such a way that they do not hinder with the user’s traditional friends; dogs, and sticks. This makes these devices effective and practical.

1. na:vi: GPS navigating system
The “na:vi” is the GPS navigating system with a sole purpose of helping the visually impaired navigate with ease and independence. Along with the basic features of a navigator, na:vi also has guiding gyroscopes and laser range finder. Moreover, with its 3D user interface, the device ensures safe and accurate operation. Its elegant design seals the beauty.
2. Munivo handheld navigation device directs the blind to walk free
Munivo handheld navigation device is designed in such a way that the user – visually impaired person – does not think he/she is holding a separate device. This device fits into the palm and maps the paths in the palm, which can be felt by the person – who are known to have increased sensitivity of other sense organs. This map is generated by using various means that can be detected by skin, such as temperature, vibration, and electro cutaneous stimulation. Ultrasound technology is used in this device for exceptional operation. This technology is basically used to measure distances between the holder and the obstacles, thus helping the person avoid them without much ado. The signals are sent through the actuators present in the silicon films that, in turn, are in direct contact with the palm, and are instrumental in sending all the signals.
3. Touch & Go navigator
A product of Natalia Ponomareva, the “Touch & Go” is a navigation system for the visually impaired people who navigate them in the outside world. This device makes them independent of others. It is a two-piece device: an earpiece and a hand piece. The beautiful look of this gadget helps it to function as an accessory as well. The direction the user has to go is shown by an arrow. These directions can also be found out by the auditory system provided by the device through the earphone.
4. Brainovi 3D Braille GPS navigation system
The Brainovi is a device that is based on the coordination between audio guiding system, via a Bluetooth earpiece, and a physical three-dimensional map, which develops on the pin matrix surface of the Brainovi. The best part about the device is that the user does not have to specifically point out the location by the finger. Merely uttering the location can make this device map out the best possible route to reach it. However, its main drawback is the presence of the handheld device that may hinder the person’s activities that require a stick.
