The time of the COVID-19 pandemic is still ongoing and it is uncertain when it will end, so contributions from universities are needed in terms of innovation to anticipate the spread of COVID-19. This paper reports on the development of a temperature measurement application for early detection of COVID-19 based on Interactive Augmented Reality (IAR) technology and the MLX90614 sensor by knowing the framework and application prototyping. The application development method used is Extreme Programming (XP) which is a type of Agile Process and implements testing of application features with black-box and the precision of the application. The result of this research is that an application framework is produced, namely, the user opens the IAR camera application then directs the MLX90614 sensor to the target, the target immediately directs his face to the IAR camera, so that the results of body temperature detection can be tracked and visualized the results on the IAR user interface. The IAR camera function is to generate visualization in the form of detection result information into a user interface modeling. Furthermore, for the black-box test results, it was found that all the features of the application were functioning properly and the precision testing results were 94.44% with a very good category. In the future, the features and performance of the application will be improved as well as the efficiency of the form of the device used so that it can be used by the general public.

The use of technology to improve the experience and teaching and learning process in the classroom has been promoted now. One of these technologies is Augmented Reality (AR). Users are in a virtual space while still having nuances in real life called AR. AR has been proven to offer several solutions in the context of education, namely increasing learning involvement and increasing understanding of some materials. This study proposes AR-assisted learning media with the method of 3D Based Tracking and audio Marker, which is used by preschool children to recognize animals and fruits in English alphabetically, then analyze, evaluate, and know the effects on their use. The Extreme Programming (XP) method is used as an application development method. Application testing is done by black box testing, testing variations between distance, angle, lighting, background, and font size of the marker, and AR-Child response time to the detection of markers by the camera for the appearance of virtual objects. Thirty preschool children aged 4-6 years were involved in using the AR-Child application and analyzing application testing on the attractiveness and fun elements of students with fun testing. The effect of using ARChild is seen from the learning outcomes at the end of the second meeting.

The development of Augmented Reality (AR) technology until now continues to increase. Utilization of AR has been used in various aspects of life, including aspects of education, is no exception for automotive engineering education. In recent years, a variety of ideas and the latest innovations about automotive by utilizing AR technology began to boom, especially in the area of car design aimed at car production companies. At the car production stage, human resources skilled in understanding the design and specifications of car features are required. The seeds of educated human resources start from vocational students in automotive engineering expertise programs.

Over the last few years, communication latency has been a major hurdle for most of the applications deployed in different network domains. During this era, a number of communication protocols and standards were developed and used by the community. However, still the problem of latency persists keeping in view of the Quality of Service (QoS) and Quality of Experience (QoE) for different applications. To mitigate the aforementioned issues, in this paper, we present an in-depth survey of state-of-the art proposals having Tactile Internet as a backbone for delay mitigation using 5G networks for future ultra reliable low latency applications such as-Healthcare 4.0, Industry 4.0, Virtual Reality and Augmented Reality and smart Education. From the existing proposals, it has been observed that Tactile Internet can provide interactions between virtual objects to givea feel of real environment with maximum latency of 1ms. Also, this paper highlights the key differences between the Tactile Internet and Internet of Things in context with 5G revolution. Then, open issues and challenges of Tactile Internet for smart applications are analyzed. Finally, a comparison of existing proposals with respect to various parameters is presented which allows the end users to select one of the proposals in comparison to its merits over the others.

Language is one of the fundamental factors that distinguish humans from animals. Language allows individuals to live together, help solve problems and position themselves as cultured beings. Language is a communication medium that aims to understand each particular ethnicity and nation. Language comprehension allows increased awareness and value of closeness between individuals in an area. However, a large number of languages seem to be the cause of difficulties and misunderstandings about the meaning of certain words. This research provides alternative solutions for solving these problems. This solution can provide convenience in the process of understanding the meaning of language words, especially Banjar Language, by recommending an application called “BandoAR”. BandoAR is a translator application from Banjar Language to Indonesian. This application can work as a real-time application without requiring input media such as text that must be typed using a good camera quality and has autofocus characteristics on the camera. This study emphasizes the process of detecting and tracer texts that exist in the Banjar community. This research is intended to see how Augmented Reality technology can be applied in the text without markers and has different font sizes, backgrounds, and distances. The results show that software for Android smartphones, as a media translator in real time, can be used in almost every type of smartphone. Based on internal trials and the results of 160 respondents, this application can attract users’ interest, can be applied in real life, and as an effort to preserve Banjar Language culture.

This research proposes a head movement recognition method based on Android internal Gyroscope sensor. The contribution of this research is to proposes head movement as a new way of Human-Computer Interaction approach on Android smartphone. The head movement which has been used was an advanced movement from the single movement to the combination movement. Another challenge was head identification process based on built-in Android gyroscope sensor, which the sensor in the Android produced data noisier than the sensor in the iOS. Based on that, a preprocessing method has been proposed to enhance the head movement recognition. After the preprocessing phase, the head movement recognition phase conducted by the Nearest-Neighbour Classification Algorithm. Based on the proposed method, a controller application prototype has been made and deployed into the smartphone which combined with the dummy HMD to be used on the head. The experiment has been conducted on different hardware environments to understand the robustness of the proposed method. Based on the accuracy experiment, the success rate of our proposed method was about 95%. Based on the performance experiment, the average of the time amounts to execute the identification process was about 2.5 ms, which less than 100ms. Based on the experiment result, our proposed method is appropriate for a new experience of real-time human-computer interaction with head movement control only, although in a different hardware environment.

Virtual reality has been implemented in many fields recently escpecially in education because its capability to produce a virtual world and take users to experience in different level with lower cost. The users will interact with the virtual world using their body or some parts of body such us head, hand, or voice. The problem of recognition accuracy level is still a challenging problem. This research is focused on comparing head movement recognition algorithms in a simple educative mobile application. Accelerometer sensor and RGB camera in Kinect are used to capture five basic head movements; nodding, shaking, looking up, looking down, tilting. Three different algorithms are used to recognize the movement; backpropagation neural network, dynamic time wrapping and convolutional neural network. The result reveals that accelerometer-based dynamic time wrapping method is the best method in recognizing the head movement with 80% accuracy level, followed by backpropagation neural network and convolutional neural network.
