“…For this purpose, integrated humidity-temperature sensors are usually applied to track historical trends and patterns, then analyze the data for conducting quantitation of both humidity and temperature levels, in which the humidity element measures the amount of moisture or water vapor present in the air, typically expressed as a percentage relative to the maximum moisture capacity of the air, i.e., Relative Humidity (RH), and temperature element measures the changes in a particular physical property (electrical resistance, voltage, or frequency) that is affected by ambient temperatures. Zhangaskanov et al [39] modified the white stick by allocating a number of sensors at different angles to perform interactions with surroundings, including the DHT11 sensor for humidity-temperature monitoring.…”

“…Next, in order to enhance the perception of surroundings for visually impaired individuals, the design focuses on incorporating humidity-temperature monitoring and fall detection capabilities into the walking stick. For this purpose, on the one hand, referenced by [39], the DHT11 sensor, which includes a calibration unit, is utilized. This sensor uses digital module acquisition and humidity-temperature sensing technologies, integrating a resistive moisture sensing element and a Negative Temperature Coefficient (NTC) tem- Second, as the size and wavelength distribution of the infrared radiation energy of an object is closely related to its surface temperature, the surface temperature can be determined by measuring infrared radiation [45].…”

In this work, an assistance system based on the Artificial Intelligence of Things (AIoT) framework was designed and implemented to provide convenience for visually impaired people. This system aims to be low-cost and multi-functional with object detection, obstacle distance measurement, and text recognition achieved by wearable smart glasses, heart rate detection, fall detection, body temperature measurement, and humidity-temperature monitoring offered by an intelligent walking stick. The total hardware cost is approximately $66.8, as diverse low-cost sensors and modules are embedded. Meanwhile, a voice assistant is adopted, which helps to convey detection results to users. As for the performance evaluation, the accuracies of object detection and text recognition in the wearable smart glasses experiments are 92.16% and 99.91%, respectively, and the maximum deviation rate compared to the mobile app on obstacle distance measurement is 6.32%. In addition, the intelligent walking stick experiments indicate that the maximum deviation rates compared to the commercial devices on heart rate detection, body temperature measurement, and humidity-temperature monitoring are 3.52%, 0.19%, and 3.13%, respectively, and the fall detection accuracy is 87.33%. Such results demonstrate that the proposed assistance system yields reliable performances similar to commercial devices and is impressive when considering the total cost as a primary concern. Consequently, it satisfies the fundamental requirements of daily life, benefiting the safety and well-being of visually impaired people.

“…This reduced amount of instruction was intended to reduce the learning time of using the system. The use of spoken instructions is intended to alleviate the user's doubts about the action to be taken, as described in Zhangaskanov's approach, through two short phrases indicating "high ground obstacle" and "low ground obstacle", and the approach described by Spagnol, who used a bubble triggering scheme in a container www.videleaf.com containing liquid [27,28]. The six spoken instructions and actions to be taken by users are shown in Table 2.…”

“…Feedback can be defined as the means used by the system to convey information to the BVIP. Aid systems use audio [ 6 , 29 , 32 , 69 , 164 , 165 ], haptic [ 25 , 166 , 167 ], or a combination of these two [ 50 , 168 ]. Using headphones (sound feedback) to receive information from the system has the disadvantage of blocking out other audio information for the user, affecting their perception of a surrounding [ 10 , 168 ].…”

Blind and Visually impaired people (BVIP) face a range of practical difficulties when undertaking outdoor journeys as pedestrians. Over the past decade, a variety of assistive devices have been researched and developed to help BVIP navigate more safely and independently. In addition, research in overlapping domains are addressing the problem of automatic environment interpretation using computer vision and machine learning, particularly deep learning, approaches. Our aim in this article is to present a comprehensive review of research directly in, or relevant to, assistive outdoor navigation for BVIP. We breakdown the navigation area into a series of navigation phases and tasks. We then use this structure for our systematic review of research, analysing articles, methods, datasets and current limitations by task. We also provide an overview of commercial and non-commercial navigation applications targeted at BVIP. Our review contributes to the body of knowledge by providing a comprehensive, structured analysis of work in the domain, including the state of the art, and guidance on future directions. It will support both researchers and other stakeholders in the domain to establish an informed view of research progress.
