Vision is extremely important in our lives. The loss of sight is a serious issue for anyone. According to the WHO, one-sixth of the world's population suffers from vision impairment. According to World Health Organization (WHO) statistics published in December 2021, more than 283 million people worldwide suffer from sight problems, including 39 million blind people and 228 million people with low vision. Navigation in unfamiliar environments is a significant challenge for the partially sighted and visually impaired. Improving visual information on object location and content can aid navigation in unfamiliar environments. Many efforts have been made over the years to develop various devices to assist the visually impaired and improve their quality of life. Numerous efforts have been made over the decades to develop gadgets to support the visually impaired as well as enhance the quality of their lives by trying to make them skilled. There are many existing navigation alternatives that can aid these people. However, in practice, navigation alternatives are infrequently adopted and implemented. For universal use, many of these gadgets are either too heavy or too expensive. While emphasizing related strengths and limitations, it is necessary to produce a minimally expensive assistive device for people with visual disabilities. The proposed model provides an efficient solution for VIPs to roam from place to place by themselves through smart applications with AI and sensor technology. The smart application captures and classifies the images. The obstacles are detected through ultrasonic sensors. The user can get a sense of the obstacles in the path through voice command. The proposed model is very helpful for the VIPs in terms of qualitative and quantitative performance measures. This enables a ranking of the evaluated systems according to their potential influence on Visually Impaired people's lives.

“…Although the Optacon is no longer in production, existing units are still in use by a group of people who find its capabilities indispensable. An alternative integrates piezoelectric bending beam actuators perpendicular to the tactile sensing plane, enabling large bending beam actuators to be tightly packed for fully 2D displays [61]. The large amount of piezoelectric material required potentially increases the cost of this type of architecture, as for other piezoelectric bending beam actuator systems.…”

As the largest organ in the human body, the skin provides the important sensory channel for humans to receive external stimulations based on touch. By the information perceived through touch, people can feel and guess the properties of objects, like weight, temperature, textures, and motion, etc. In fact, those properties are nerve stimuli to our brain received by different kinds of receptors in the skin. Mechanical, electrical, and thermal stimuli can stimulate these receptors and cause different information to be conveyed through the nerves. Technologies for actuators to provide mechanical, electrical or thermal stimuli have been developed. These include static or vibrational actuation, electrostatic stimulation, focused ultrasound, and more. Smart materials, such as piezoelectric materials, carbon nanotubes, and shape memory alloys, play important roles in providing actuation for tactile sensation. This paper aims to review the background biological knowledge of human tactile sensing, to give an understanding of how we sense and interact with the world through the sense of touch, as well as the conventional and state-of-the-art technologies of tactile actuators for tactile feedback delivery.

“…Walking aids for the BVI have been extensively studied regarding their ability to provide vibrotactile feedback; such feedback is used as an alternative sensory modality for the BVI [5,6]. These aids are available in numerous forms ranging from portable devices such as modified white canes [7,8]; hand-held devices [9]; and wearable devices such as waist belt-type [10][11][12][13], vests [14][15][16][17][18], head mounts [19,20], ear-shaped earphones [21], footwear [22], and necklace-type [23]. These tactile displays solely provide either information about obstacle presence or directional cues for obstacle avoid-ance, but not both simultaneously.…”

Considering the ambulatory principles for the blind and visually impaired individuals (BVI), who encounter difficulties in independent walking and wayfinding, the acquisition of diverse types of information is required. For independent walking, the spatial and status information are required in addition to directional information. However, delivering information of several types poses a problem because it decreases the perception rate of the information. To address this problem, we applied a strategy that configures the group of vibrotactile information by combining both stationary and moving tactons, as opposed to using stationary or moving alone. In this study, we introduce a novel wrist-worn tactile display with eight vibrators, which can deliver easily distinguishable directional, spatial, and status information. For improving the recognition rate of information provided, the vibration patterns were categorized according to spatial characteristics and were provided to express the different types of information. Through the preliminary study, it was confirmed that the capacity of information transmission improved significantly when employing a combination of stationary and moving tactons, as opposed to relying solely on stationary or moving tactons. The effectiveness of the proposed device was evaluated through user tests with the blind and visually impaired participants. Overall, the categorized vibrotactile information was quickly identified, and it enabled the blind to walk independently without any pre-learned knowledge about the route.
