This review investigates the problem of hospital orientation touchpoints for individuals with visual impairments. This paper aims to provide a framework for the service design considerations that designers and engineers of medical devices must consider to aid the visually impaired people in the hospital orientation. In addition, service design and design thinking techniques were utilized to synthesize the findings. Four-person focus groups were used to conduct semi-structured interviews. Using purposeful sampling, a group of Yinchuan, China, visually impaired people were chosen to be interviewed and guided through a series of fictitious medical crises. Using a user journey map and service touchpoint analysis, the service touchpoints encountered by the visually impaired population while using the guided care service were summarized and unified, yielding into several design recommendations. Based on the research provided in the research on assistive device design for the visually impaired population and the collected studies on hospital guidance services, current research on hospital guidance services is focused more on changing service design from the hospital perspective. The potential scenario applications of this wearable device have been largely neglected in previous studies on the design of assistive devices for people with visual impairment. Finally, the contact points that visually impaired people will encounter in the hospital alone were divided into three: before, during, and after the visit. These contacts were divided into eight categories. Although research on inclusive design and related topics from the perspective of the visually impaired has increased, very little has been done to examine this issue from the perspective of actual use cases. Despite the importance of the design and technology phases of product development, there is still a need for further research into the design of antecedent services in the context of what people with visual impairment require.

Abstract: Brain computer interface (BCI) system empowers command over external device by retrieving brain waves and interpreting them into machine instructions. The system utilizes electroencephalogram (EEG) for receiving, processing and classifying signals to control by means of brain generated signals. The paper focused on mental task designs for BCI by acquiring the signals generated by mental activity using EEG comb electrodes, placed over three-dimensional (3D) printed headset. The experiment involved the blinking of left and right eyes for the forward and backward movements of the prototype wheelchair. The experimental measurement was performed using a Cyton board where the information was transmitted through Bluetooth which were later processed and translated to the wheelchair to perform activities. The system has successfully achieved the real time control of an assistive device by using signals from the brain.

Ultraviolet-C (UVC) sourced has been widely used for the purpose of disinfection due to its germicidal spectrum. In this study, the effectiveness of Everlight’s 275 nm Ultraviolet-C surface mounted device (UVC-SMD) to disinfect Staphylococcus aureus (S. aureus) was investigated at three exposure durations (10, 30 and 60 s) for a standard distance of 5 cm. The inhibition zones were greater with the increment of exposure duration. The highest records of 4.53 ± 0.03 cm were achieved when 102 mJ/cm² of dose was applied at a distance of 5 cm for 60 s. Whereas, on the other side, the lowest inhibition was seen when the exposure was set for 10 s. Thus, the Everlight 6565 UVC-SMD with 275 nm of wavelength is capable in providing bacterial disinfection which could possibly be used for the development of disinfection system based on SMDs at longer exposure duration.

The advancement of technology has witnessed the increasing use of game-based intervention and it is proven beneficial for people with specific learning disorder such as Dyslexia. Initially developed for entertainment, a game is generally considered a tool with the key features of challenge, motivation, and rewards which add more fun and excitement to Dyslexia teaching and learning. Many game applications have been developed in the area; each incorporates several criteria to meet the specific needs of the dyslexics. To date, these criteria are still dispersed in numerous publications, leading to the duplication of basic games that have previously been developed by others. This study aimed to identify the dispersed criteria by adopting PRISMA approach in the systematic literature review, and analyze them to formulate a comprehensive guideline for future design and development of the dyslexic games. Five main databases were chosen which are Scopus, ACM Digital Library, EBSCO-host, Wiley and Web of Science (WOS). Out of 551 articles that have been screened, only 50 articles were eligible to be analyzed based on the relevancy to the criteria, and only 23 articles were included in the study after further screening. A total of 135 criteria were identified with some redundancies, and were further classified into four categories: device and platform; features; interface and gameplay. These criteria can be utilized by the educational game developers as reference when designing the dyslexic games. A better dyslexic-friendly games could be produced when the developers design it with their special learning needs in mind.
技术的进步见证了基于游戏的干预越来越多的使用，它被证明对患有特殊学习障碍(如阅读障碍)的人有益。游戏最初是为娱乐而开发的，通常被认为是一种具有挑战、动机和奖励等关键特征的工具，为阅读障碍的教学和学习增加了更多的乐趣和兴奋。该地区开发了许多游戏应用程序;每一个都包含了几个标准，以满足阅读障碍患者的特定需求。到目前为止，这些标准仍然分散在许多出版物中，导致了其他人之前开发的基本游戏的复制。本研究旨在通过系统的文献综述，采用PRISMA方法找出分散的标准，并对其进行分析，为今后设计和开发阅读障碍游戏制定一个综合的指导方针。主要选择Scopus、ACM数字图书馆、EBSCO-host、Wiley和Web of Science (WOS) 5个数据库。在筛选的551篇文章中，根据与标准的相关性，只有50篇文章符合分析条件，在进一步筛选后，只有23篇文章被纳入研究。共确定了135个标准，其中有些冗余，并进一步分为四类:设备和平台;功能;界面和玩法。这些标准可供教育游戏开发者在设计阅读障碍类游戏时参考。当开发者在设计游戏时考虑到他们的特殊学习需求时，便能够创造出一款更适合阅读障碍者的游戏。

Cognitive skills are one of the components of mental skills. These skills deal with a high level of cognitive processing, including decision-making. Athletes with high cognitive skills have superior positive thinking and decision-making. The objectives of this study are to evaluate mental skills performance on athletes and non-athletes in university and to investigate the difference of mental skills among athletes and non-athletes in university. 229 active students from Bachelor of Sports Science, Universiti Teknologi MARA Perlis Branch participated in this study. Descriptive statistical methods were used using Microsoft Excel 2020 and the Statistical Package for the Social Sciences (SPSS 25.0 version). The significant value for determining the significant difference of the data gathered was valued as p < 0.001 and p < 0.05. All descriptive data calculated were presented in mean ± standard deviation (SD). A statistically significant of the result for vigilance’s approach showed that there was no significant difference between athletes and non-athletes. As for buck-passing and procrastination approach, there was a significant difference recorded as the test result indicated p < 0.001 and p < 0.05 respectively. Lastly, hypervigilance approach showed that there was a significant difference between athletes and non-athletes with the value p < 0.001. This study suggests that there is a significant difference of buck-passing, procrastination and hypervigilance between athletes and non-athletes among university students. Future study can consider investigating demographic and athletes’ competitiveness factors to understand better on the underlying influences on how individual participation and exposure in sports affecting mental skills development.

Killing or spiking is one of the tactical moves in Sepak Takraw that can help to decide the outcome of a match. This study aimed to explore the relationship between various elements of Sepak Takraw, including spiking technique, point succession, spiking zone, and point area. In this study, the researchers also sought to determine whether the variables, zone of spiking and point succession are related to the point area. The sample consisted of 19 matches from the 2021 STL Champions Cup, with 315 spiking attempts recorded. The data were collected through notational analysis and analyzed using statistical methods of Crosstabs and Chi-Square tests (with a significance level of p < 0.05), through SPSS version 25. The findings showed no significant connection between the spiking technique and the point succession (p = 0.831), or between the spiking technique and the spiking zone (p = 0.730) and between the area of point and the point succession (p = 0.253). However, there was a significant correlation between the spiking technique and the point area (p = 0.001), as well as between the point area and the spiking zone (p = 0.016). These results indicate that proper spiking technique can significantly impact the outcome of Sepak Takraw match and further research is needed to investigate the role of other tactical elements, such as serving, blocking, and rally play.

Pneumonia and COVID-19 are the most infected infectious diseases that deteriorate health of all range of people. If the early treatment is not provided, it may lead to severe heart disease and eventually to mortality. Therefore, continuous heart rate (HR), as well as blood oxygen saturation (SpO2) monitoring can help to detect abnormalities early. As a result, this paper presents a combination of portable continuous SpO2 and HR monitor which focuses on the improvement of internal design and graphical user interface of the mobile application. In this system, MAX30100, a photoplethysmography (PPG) sensor, was used to measure SpO2 and HR. Then, the signal was transmitted to Arduino Nano as the master microcontroller to process all acquired data from the sensor. The device was integrated with Android-based mobile application through Bluetooth communication, for displaying the result of the measured real-time parameters continuously and for battery status indication. Quantitative measurements showed that the precision of the circuit system implemented for HR and SpO2 were 99.16% and 99.06%, respectively. This system would improve the working efficiency and life efficiency of the healthcare provider and public.

To overcome limitation in equine gait monitoring, a low-cost monitoring device is needed especially for long-distance event performance monitoring. Current devices capture horse gait in limited range of distance, limited duration usage and expensive. Mobile application such as Androsensor has shown a great potential in horse gait recognition. However, further study is still warranted in order to determine the reliability of this kind of mobile application for performance monitoring especially for long-distance event such as endurance. In this study, a validation test of Androsensor mobile application for equine gait patterns recognition was conducted before the data can be applied for long-distance performance monitoring. Two horses (Thoroughbred) were used in this preliminary study. A unit of inertia measurement unit sensor (IMU) (Delsys Trigno Avanti Sensor) with 150 Hz sampling rate and a mini smartphone installed with Androsensor apps with 200 Hz sampling rate were attached together on horse forelimb pastern to compare the acceleration of horse gait signal captured by both devices. The data captured by both devices were analyzed. The correlation coefficient between an established device (IMU) and the Androsensor apps have shown a good correlation with higher correlation coefficient (r > 0.5) for walk, trot and canter. This finding indicates that the Androsensor mobile application has a great potential to be used in equine gait research and performance monitoring. It also can offer a wide function in this field as it is cheap and wearable.

Brain computer interface (BCI) system empowers command over external device by retrieving brain waves and interpreting them into machine instructions. The system utilizes electroencephalogram (EEG) for receiving, processing and classifying signals to control by means of brain generated signals. The paper focuses on mental task design for BCI by acquiring the signals generated by mental activity through EEG comb electrodes, placed over three-dimensional (3D) printed headset. The experiment involved the blinking of left and right eye for the forward and backward movements of the prototype wheelchair. The experimental measurement was performed using a Cyton board where the information was transmitted through Bluetooth which were later processed and translated to the wheelchair to perform activities. The system has successfully achieved the real time control of an assistive device by using signals from the brain.

Assistive technology (AT) has made many tasks possible for people with disabilities. Unfortunately, almost no technology is developed centered around the blind people of developing countries when it comes to navigating. This study explored blind people's concerns and determined the type of design and interaction of a navigation application that are more convenient and favored by blind users. Qualitative research was used to study the problems faced by blind people of developing countries while navigating. Blind people of two organizations in Bangladesh participated voluntarily in the research. The data obtained were analyzed using thematic analysis of ATLAS.ti. The data indicated that merely traveling with the white cane was not enough and there were a lot of problems faced when going from one place to another. A preference was shown for voice-assisted devices. The data were used to build two types of accessible prototypes with good UX, but different interactions, design, layout, spoken content and audio descriptions. Later, the usability testing was performed to investigate the effectiveness of the two types of prototypes from the UI/UX perspective. The results indicated that there was a greater preference for a layout with more spacing and buttons closer to the hands. Audio descriptions, spoken content and being able to navigate using the application also instills a sense of independence. The study contributes to a better knowledge of design solutions and interactions that legally blind people prefer, and to the creation of navigation tools/apps for the blind, specifically from the developing countries such as Bangladesh.
