Visually impaired people must use a device to assist them in walking safely. The most commonly used assistant walking device is a white cane. However, there are many problems with this. It is difficult to prepare for falls because the hand using the white cane is not free, and the body could feel unbalanced while using it.
In this study, a new walking assistance device that can solve these problems and replace the white cane is developed. The device is wearable and attachable to one’s shoes. It has an infrared sensor, pressure sensor and vibrating motor, and can help the individual walk safely by detecting obstacles around them.
A experimental obstacle area was designed to create an evaluation of the walking assistance shoe device. The subjects in this study were both visually impaired and non visually impaired people. In the study, they used the developed walking assistance shoes once, and used the white cane once while walking through the designed obstacle area.
We measured the following: time required for passing through the designed area, number of collisions with installed obstacles. We also measured EMG(Electromyograph) of the tibialis anterior, vastus laterals, biceps femoris and lateral gastrocnemius to compare lower limb balance when using the walking assistance shoes and with the white cane.
As for the results, using the walking assistance shoes we developed resulted in a slower walking speed than using the white cane. However, our device has a better rate of detecting obstacles and can reduce the body imbalance by helping the wearer use their lower limbs evenly. The result of this study can help in the development of the wearable device for visually impaired individuals.
