“…Nowadays, most of the agricultural field work is done by machines that are operated by people in farming and there is an increasing trend in study into integrating AR in agriculture (Huuskonen and Oksanen, 2018). The use of AR in agriculture will enable farmers to produce a better and larger yield (Pandey et al, 2020). Therefore, the objective of this study was conducted to determine the usability of augmented reality (AR) application in 'Fertigation System' among Form 1 students who took Design and Technology subject at Sekolah Menengah Kebangsaan Behrang 2020, Perak, Malaysia.…”

The purpose of teaching aid is important to attract students to always be active in the classroom. It is important to focus on educational activities among students such as the usage of teaching aid during the teaching and learning process. Therefore, the objective of this study is to identify the usability of augmented reality (AR) application 'Fertigation System' among form 1 students of SMK Behrang 2020 who took Design and Technology subject. The application was developed using the ADDIE model which has five phases including analysis, design, development, implementation, and evaluation. The design of the studies used was quantitative method (survey method). The instrument of study used was a questionnaire. In the first phase (Analysis), a questionnaire that was endorsed by experts was distributed to 35 respondents to identify the needs of the AR application development. In this phase, there were 72% of respondents agreed the needs of the AR application development. For the next phases, an AR 'Fertigation System' has been designed and developed. A questionnaire was distributed together with the AR application that has been developed and verified by three experts from different fields (language, education, content). After that, a pilot study was conducted among 50 students of form 1 who took Design and Technology subject at SMK Behrang 2020 as respondents for improvement purposes (Implementation phase). For the final phase (Evaluation), a questionnaire and application of AR 'Fertigation System' which has been verified and improved was distributed to 76 respondents comprising form 1 students who took Design and Technology subject at SMK Behrang 2020. The results of this study showed that 62.72% of the respondents strongly agreed with the usability of the AR application 'Fertigation System'. All data obtained was analyzed using the Statistical Package for Social Science (SPSS) to obtain the average value, percentage, frequency and standard deviation. In conclusion, the results of this study show that the AR application of the 'Fertigation System' that has been developed can be used among form 1 students who took Design and Technology subject at SMK Behrang 2020, Perak.

“…Furthermore, recent studies in agri-research and -business have brought about the development of virtual reality (VR), augmented reality, substitutional reality, mixed reality (MR), and cross or extended reality (XR) systems [3]- [8]. Many of these employ the latest VR tech-based trends in agriculture with a focus on human-engineering (kinematics) and other human-based sciences and technologies.…”

In this study, we develop a virtual reality (VR)–based agricultural (hereinafter, agri-) support technique to assist in training newcomers and trainees in agricultural work. The system consists of a head-mounted display (HMD)—a HTC Vive Pro Eye—gaming personal computer, and peripheral components. The HMD-based system consists of the following: (1) a precision eye-tracking system for tracking and interpreting eye movements to enable lifelike interactions, better manage GPU workload, and simplify input and navigation; (2) a room area tracker up to 100 m²; and (3) a VR-space experience with unmatched tracking accuracy with SteamVR™ Tracking. The agri-situation considered in this study is non-specific tomato harvesting performed by inexperienced agri-workers. The study aims to (1) measure and analyze persons’ cognition and behavior indicators in VR-based environments that simulate the work site, (2) provide suggestions regarding analyses of processes from the cognition of targets to specific behaviors using objective indexes; and (3) realize in advance the verification and comparison of improvements of measures related to specific agri-works without the need to utilize actual agri-work sites. Specifically, we utilize and apply the eye-tracking function incorporated in the HMD, in addition, we develop a Unity-based VR system with sound notification to indicate the validity of eye-tracking and the motion of manual agri-workers and managers. Subsequently, we conduct experimental trials in a non-specific room. In the trials, subjects wearing the HMD system sequentially gaze at figures of small red tomatoes in the VR spaces. In the process, the VR system plays alerts to notify subjects when they gaze at or miss the target tomatoes. The system provides quick and accurate operations, and the eye-tracking function of the system differs from existing agri-training-oriented techniques and products. The system has several advantages such as lower cost compared with existing similar mechanical systems found in the literature and similar commercial products. In addition, the Unity-based system is a minimal and flexibly scalable system that can be adjusted to suit future studies and expansion for different agri-situations. This study consists of five phases: (1) designing and confirming the validity of the system; (2) accumulating image data on outdoor farmland; (3) constructing the entire system and tuning various minor system settings like program parameters and other specifications; (4) executing experiments in an indoor room; and (5) assessing and discussing the results and gathering comments from the subjects and presenting the characteristics of these trials. We consider that, from the limited trials, the system can be judged to be valid to some extent in certain situations. However, we could not perform broader or more generalizable experiments using the system. We present experimental characteristics and numerical ranges related to the trials, particularly noting speed and likelihood of mistakes concerning the system’s practical operations. The novel achievements of this study lie in the fusion of the latest HMD and Unity-based agricultural training facilities. In future, agri-workers and managers can use the proposed system for training, particularly for eye movement. Furthermore, we believe that, by combining this system with other existing systems, agriculture can be greatly improved.
