“…There is a lot of research on navigation systems, usually using five technologies: radio frequency identification (RFID), ultra-wideband (UWB), near-field communication (NFC), Bluetooth Low Energy (BLE), and infrared (IR) [3][4][5][6][7][8][9][10][11]. G. A. M. Madrigal et al [4] and C. M. Yang et al [7] adopted the RFID system to provide information about the user s location in indoor spaces. The SUGAR system [8] uses UWB for positioning, which performs with a high level of accuracy.…”

“…Unfortunately, few existing intelligent tools take this into account. For example, C. M. Yang et al [7] and A. Khan et al [13] used three ultrasonic sensors installed in three different directions on a white cane to detect low obstacles without considering aerial obstacles.…”

“…Non-vision-based systems can also have the following functions: voice and vibrate alert, GPS positioning, obstacle detection, navigation [3][4][5][6][7][8][9][10][11][12][13][14][15], etc. The existing intelligent tools almost stay at the sensor level, and their functions are relatively singular.…”

Visually impaired people face many inconveniences in daily life, and there are problems such as high prices and single functions in the market of assistance tools for visually impaired people. In this work, we designed and implemented a low-cost intelligent assistance cane, particularly for visually impaired individuals, based on computer vision, sensors, and an edge-cloud collaboration scheme. Obstacle detection, fall detection, and traffic light detection functions have been designed and integrated for the convenience of moving for visually impaired people. We have also designed an image captioning function and object detection function with high-speed processing capability based on an edge-cloud collaboration scheme to improve the user experience. Experiments show that the performance metrics have an aerial obstacle detection accuracy of 92.5%, fall detection accuracy of 90%, and average image retrieval period of 1.124 s. It proves the characteristics of low power consumption, strong real-time performance, adaptability to multiple scenarios, and convenience, which can ensure the safety of visually impaired people when moving and can help them better perceive and understand the surrounding environment.

The Functionalities and Technologies Trends in Developing Electronic Travel Aids for the Blind or Visually Impaired People: A Review

In all parts of the community, basic autonomous navigation is essential. The capability to navigate complicated environments allows people to achieve a wide range of physical and mental objectives. With minimal non-visual infrastructure, indoor navigation is a complicated cognitive and perceptual activity, unlike Global Positioning System (GPS) infrastructure for outdoor navigation. Blind or visually impaired people (BVIP) require sophisticated technologies with inbuilt functionalities for obstacle detection and recognition and the identification of desired destinations like rooms, stairs, and elevators to better orient themselves and navigate in unfamiliar indoor environments. Electronic travel aids (ETAs) have developed and offered exceptional navigation support for the BVIP. ETAs increase opportunities for autonomous navigation by providing information regarding the surroundings in the indoor or outdoor environment, the user's present position, and navigational instructions about the route to a targeted destination. However, less focus has been found in the literature on integrating several functions in ETAs to have a more comprehensive system that supports indoor navigation activity of BVIP to facilitate the mobility of BVIP. This study provides a thorough review of previously developed ETAs using two main criteria: the used technologies and the fulfilled functions. Based on the review findings, this study suggests future research path of technological instrumentation for the BVIP' ETA solutions in indoor navigation.
