We present a protocol for evaluating the efficiency of an electronic white cane for improving the mobility of blind people. The electronic cane used during the test is the Tom Pouce III, made of LIDAR sensors (light detection and ranging) with tactile feedback. The protocol comprises two parts. The first part, the “detection test”, evaluates the efficiency of the sensors in the Tom Pouce III for detecting the obstacles found in everyday life (thin and large poles, apertures) under different environmental conditions (darkness, sun light, rain). The second part of the test, the “mobility test”, compares the ability of blind participants to cross a 25 m path by avoiding obstacles with the simple white cane and the electronic cane. The 12 blind participants had between 2 and 20 years of experience of everyday usage of Tom Pouce devices. The results show a significant improvement in the capacity to avoid obstacles with the electronic cane relative to the simple white cane, and there was no speed difference. There was no correlation between the results and the years of experience of the users.

This paper describes the design of an operative prototype based on Internet of Things (IoT) concepts for real time monitoring of various environmental conditions using certain commonly available and low cost sensors. The various environmental conditions such as temperature, humidity, air pollution, sun light intensity and rain are continuously monitored, processed and controlled by an Arduino Uno microcontroller board with the help of several sensors. Captured data are broadcasted through internet with an ESP8266 Wi-Fi module. The projected system delivers sensors data to an API called ThingSpeak over an HTTP protocol and allows storing of data. The proposed system works well and it shows reliability. The prototype has been used to monitor and analyse real time data using graphical information of the environment.

This study aims to describe the function and style of the mural by Arnis Muhammad. Mural as art in public space, which means that the space for movement and the target audience for the audience and audience is the general public. As a two-dimensional work of art, mural is also inseparable from style. Visually, the style in a work of art is the selection of objects, techniques, colors, and environmental conditions, time, era, and environmental conditions in which an artist creates his work. The population in this research is that all of Arnis Muhammad's mural works for the 2017-2019 period are 51 works. In this study the authors took samples using purposive sampling technique. The reason for taking samples is the number of mural works that still exist and are still intact. There are 10 mural works in the research location. In this case, the writer examines these mural works based on their function and style. The method used in this research is descriptive qualitative method. The function of the mural by Arnis Muhammad is a personal function as a reflection of the resonance of the environment in which he lives. Social function, as a form of concern for the environment and the surrounding community in everyday life. Physical function, as an aesthetic value enhancer and the various ways the general public use it. Arnis Muhammad's murals tend to have a surreal and decorative style.

SummaryIn the absence of vision, mobility and orientation are challenging. Audio and tactile feedback can be used to guide visually impaired people. In this paper, we present two complementary studies on the use of vibrational cues for hand guidance during the exploration of itineraries on a map, and whole body-guidance in a virtual environment. Concretely, we designed wearable Arduino bracelets integrating a vibratory motor producing multiple patterns of pulses. In a first study, this bracelet was used for guiding the hand along unknown routes on an interactive tactile map. A wizard-of-Oz study with six blindfolded participants showed that tactons, vibrational patterns, may be more efficient than audio cues for indicating directions. In a second study, this bracelet was used by blindfolded participants to navigate in a virtual environment. The results presented here show that it is possible to significantly decrease travel distance with vibrational cues. To sum up, these preliminary but complementary studies suggest the interest of vibrational feedback in assistive technology for mobility and orientation for blind people.

In this paper, we present the results of an empirical study that aims to evaluate the performance of sighted and blind people to discriminate web page structures using vibrotactile feedback. The proposed visuo-tactile substitution system is based on a portable and economical solution that can be used in noisy and public environments. It converts the visual structures of web pages into tactile landscapes that can be explored on any mobile touchscreen device. The light contrasts overflown by the fingers are dynamically captured, sent to a micro-controller, translated into vibrating patterns that vary in intensity, frequency and temperature, and then reproduced by our actuators on the skin at the location defined by the user. The performance of the proposed system is measured in terms of perception of frequency and intensity thresholds and qualitative understanding of the shapes displayed.

Walking is very important in our daily lives. However, for blind people, current facility and environment are not convenient for them to walk. And due to some current problems, white canes require more attention from the society and need to be improved. This study combined the engineering creativity theory with the creative thinking process. And interviews and records were referenced for the design improvement of white canes. Secondly, techniques from the creative design methodology were applied. After discussing and making some adjustments, this study proposed an auxiliary tool within white canes offering hints in different frequencies based on actual conditions and requirements when blind people cross a street with traffic signs, in hopes of assuring their safety when crossing a street.
