“…User interface and feedback modalities are essential features to take into consideration during system development because they have the ability to enhance the accessibility and usability of a system application [85]. This review demonstrated that audio was a common choice for feedback information to the user, which corroborates the results found in Islam et al [82] and Kuriakose et al [83].…”

“…In accordance with our findings, several studies have reported that to develop successful and satisfactory assistive technologies, the development must follow human-centered design approach [88]. Therefore, it is essential to understand how visually impaired people move in unknown environments and what are their needs and requirements [84], [85], [89]. In agreement, Kuriakose et al [83] argue that most solutions that may work in theory are not adopted in practice because they do not meet the user's requirements.…”

Wearable devices have been developed to improve the navigation of blind and visually impaired people. With technological advancements, the use and research of wearable devices have been increasing. This systematic review aimed to explore existing literature on technologies used in wearable devices intended to provide independent and safe mobility for visually impaired people. Searches were conducted in six electronic databases (PubMed, Web of Science, Scopus, Cochrane, ACM Digital Library and SciELO). Our systematic review included 61 studies. The results show that the majority of studies used audio information as a feedback interface and a combination of technologies for obstacle detectionespecially the integration of sensor-based and computer vision-based technologies. The findings also showed the importance of including visually impaired individuals during prototype usage testing and the need for including safety evaluation which is currently lacking. These results have important implications for developing wearable devices for the safe mobility of visually impaired people.

“…Navigation aids with smartphones as the core account for more than one-third of the total, and the classifications of 'with Infrastructure' and 'Alone' are similar. Computer-based systems mainly use external vision sensors to collect the required data [56,64] and rarely use pre-set infrastructure. Due to the enhancement of the computing power, portability, durability, and affordability of smartphones, systems with smartphones as the core have engendered a trend to replace these tasks with computers.…”

The innovations in the field of specialized navigation systems have become prominent research topics. As an applied science for people with special needs, navigation aids for the visually impaired are a key sociotechnique that helps users to independently navigate and access needed resources indoors and outdoors. This paper adopts the informetric analysis method to assess the current research and explore trends in navigation systems for the visually impaired based on bibliographic records retrieved from the Web of Science Core Collection (WoSCC). A total of 528 relevant publications from 2010 to 2020 were analyzed. This work answers the following questions: What are the publication characteristics and most influential publication sources? Who are the most active and influential authors? What are their research interests and primary contributions to society? What are the featured key studies in the field? What are the most popular topics and research trends, described by keywords? Additionally, we closely investigate renowned works that use different multisensor fusion methods, which are believed to be the bases of upcoming research. The key findings of this work aim to help upcoming researchers quickly move into the field, as they can easily grasp the frontiers and the trend of R&D in the research area. Moreover, we suggest the researchers embrace smartphone-based agile development, as well as pay more attention to phone-based prominent frameworks such as ARCore or ARKit, to achieve a fast prototyping for their proposed systems. This study also provides references for the associated fellows by highlighting the critical junctures of the modern assistive travel aids for people with visual impairments.

“…Falcon haptic also integrated with a laser sensor to applied in a wheelchair with the purpose is support blind people [10], and the nuclear industry [11]. For some applications used the haptic to make feedback force to the user to help avoid obstacles is as in [12], [13]. In the UAV field, the end-effector of Falcon haptic is used to set velocity command for the UAV [14], [15], and the force feedback to haptic is to help the user avoiding obstacles that closed the UAV [16]- [18].…”

Haptic devices had known as advanced technology with the goal is creating the experiences of touch by applying forces and motions to the operator based on force feedback. Especially in unmanned aerial vehicle (UAV) applications, the position of the end-effector Falcon haptic sets the velocity command for the UAV. And the operator can feel the experience vibration of the vehicle as to the acceleration or collision with other objects through a forces feedback to the haptic device. In some emergency cases, the haptic can report to the user the dangerous situation of the UAV by changing the position of the end-effector which is be obtained by changing the angle of the motor using the inverse kinematic equation. But this solution may not accurate due to the disturbance of the system. Therefore, we proposed a position controller for the haptic based on a discrete-time proportional integral derivative (PID) controller. A Novint Falcon haptic is used to demonstrate our proposal. From hardware parameters, a Jacobian matrix is calculated, which combines with the force output from the PID controller to make the torque for the motors of the haptic. The experiment was shown that the PID has high accuracy and a small error position.
