“…This sensor is always applied for detecting objects and measuring distance. Kumar et al [75] developed an ultrasonic cane for aiding the blind people to navigate. This ultrasonic cane 588 is equipped with three pairs of ultrasonic trans-receivers, thus enabling the blind people to know aerial and ground obstacles as well as potholes in front of them via audio warnings.…”

Across the world, there are approximately 253 million people with vision impairments, and assistive devices have constantly been in demand. Advanced research has led to the development of numerous assistive devices for blind people and visually impaired people (VIP) to improve their quality of life. An overview of these different types of assistive devices such as canes, glasses, hats and gloves is presented in this survey. A FCBPSS (F: function, C: context, B: behaviour, P: principle, S: state, S: structure) architecture of visual impairment assistance system is preliminarily proposed to allow other researchers to design the assistive devices with the good experience and the high performance for blind people and VIPs in the future. As VIPs and blind people may have different behaviour patterns, a criterion for classifying different types of vision impairments is presented. Subsequently, we classify the substitutive senses for visual perception into five categories: vision enhancement, audition, somatosense, visual prosthesis, and olfactory and gustation. Two commonly used feedback forms, namely audition and vibration, are elaborated.Based on literature survey, we also present a summary prospective of the development of assistive devices: add more sensing and feedback modules, use the knowledge of perception mechanism and behaviour pattern as the design guideline and design more reliable validation experiments.

“…On-board sensors on most smart canes are located either on the handgrip [6], [14], shaft [15], [16], [17], [7], [14], [7] or tip [6], [15]. Placing sensors on the handgrip or tip may involve major cane modifications [6], [14].…”

“…The shaft allows more space to place the electronic. However, this approach may involve changes in the cane center of gravity and also, in its weight [16], [15], [7], [14]. Even in a best case scenario, any modification significantly affecting a walking aid requires an extensively validation and/or certification process.…”

Telepresence robots have been recently used for Comprehensive Geriatric Assessment (CGA). Since the robot can not track a person continuously, there are several strategies to decide when to check them, from cyclic checks to simple requests from users and/or caregivers. In order to adapt to the user needs and condition, it is preferable to perform CGA as soon as regularities appear. However, this requires detection of potential issues in users to offer immediate service. In this work we propose a new low cost force sensor system to detect user's condition and attract attention of CGA robots, so they can perform a full examination on a need basis. The main advantages of this system are: i) it can be attached to any standard commercial cane; ii) its power consumption is very reduced; and iii) it provides continuous information as long as the user walks. It has been tested with several elderly volunteers in care facilities. Results have proven that the sensor readings are indeed correlated with the users' condition.

The World Health Organization (WHO) reported that there are 285 million visually-impaired people worldwide. Among these individuals, there are 39 million who are totally blind. There have been several systems designed to support visually-impaired people and to improve the quality of their lives. Unfortunately, most of these systems are limited in their capabilities. In this paper, we present a comparative survey of the wearable and portable assistive devices for visually-impaired people in order to show the progress in assistive technology for this group of people. Thus, the contribution of this literature survey is to discuss in detail the most significant devices that are presented in the literature to assist this population and highlight the improvements, advantages, disadvantages, and accuracy. Our aim is to address and present most of the issues of these systems to pave the way for other researchers to design devices that ensure safety and independent mobility to visually-impaired people.
