“…No statistically relevant differences were identified from task completion time and overall workload perspective when comparing them. An extensive literature review (52 articles) of current extended-reality technologies (virtual reality, augmented reality, and mixed reality), their application for training in manufacturing, and the benefits and limitations can be found in [17].…”

Manual work accounts for one of the largest workgroups in the European manufacturing sector, and improving the training capacity, quality, and speed brings significant competitive benefits to companies. In this context, this paper presents an informed tree search on top of a Markov chain that suggests possible next assembly steps as a key component of an innovative assembly training station for manual operations. The goal of the next step suggestions is to provide support to inexperienced workers or to assist experienced workers by providing choices for the next assembly step in an automated manner without the involvement of a human trainer on site. Data stemming from 179 experiment participants, 111 factory workers, and 68 students, were used to evaluate different prediction methods. From our analysis, Markov chains fail in new scenarios and, therefore, by using an informed tree search to predict the possible next assembly step in such situations, the prediction capability of the hybrid algorithm increases significantly while providing robust solutions to unseen scenarios. The proposed method proved to be the most efficient for next assembly step prediction among all the evaluated predictors and, thus, the most suitable method for an adaptive assembly support system such as for manual operations in industry.

Ventilator merupakan alat kesehatan yang paling dibutuhkan di masa pandemi ini. Berbagai institusi telah berusaha mengembangkan ventilator, akan tetapi banyak yang terkendala dengan hasil pengujian dan kalibrasinya yang tidak sesuai. Hal ini dikarenakan ketidaktahuan terhadap metode pengujian dan kalibrasi ventilator yang sesuai standar. Oleh karena itu, dikembangkanlah platform Platform Online Simulasi Virtual Pengujian dan Kalibrasi Ventilator Berbasis Browser. Platform ini kedepannya akan digunakan oleh institusi pengembang ventilator untuk melakukan pembelajaran dan meningkatkan kompetensi melalui pelatihan terkait pengujian dan kalibrasi ventilator. Penelitian ini dibatasi dengan menggunakan beberapa ruang lingkup pengujian yaitu tidal volume, minute volume, breath rate, I:E ratio, PEEP, inspiration time, dan Expiration time. Tahapan metode penelitian yang akan dilakukan mulai dari studi literatur, produk, library, algoritma, pengumpulan data ventilator dan gas flow analyzer, dilanjutkan dengan desain sistem, antarmuka pengguna, dan elemen visual, kemudian dilakukan pengembangan sistem dan antarmuka pengguna, lalu dilakukan pengujian fungsi, dan pengalaman pengguna. Hasil pengujian menunjukan seluruh fungsi 100% terlaksana dengan baik dan pengalaman pengguna 38% menunjukkan setuju dengan kriteria pengalaman pengguna yang terdiri dari Daya Tarik, Efisiensi, Perspicuity, Ketergantungan, Stimulasi, Novelty, Kepercayaan, Estetika, Adaptabilitas, Kegunaan, Penggunaan Intuitif, Nilai, Konten yang Dapat Dipercaya, Kualitas Isi, Haptics, dan Akustik

Wayfinding in Virtual Reality Serious Game: An Exploratory Study in the Context of User Perceived Experiences

2021

Extended reality (XR) technologies such as virtual reality (VR) provide a promising alternative for training users through serious games (SGs). VR SGs allow people to train in emergency scenarios and improve their likelihood of survival in high-risk situations. Studies have shown that incorporating design elements such as wayfinding cues enhances the spatial knowledge of users in VR. However, the impact of these wayfinding cues on users’ psychological and psychometric behaviors needs thorough investigation. An SG was designed to investigate wayfinding cues’ psychological and psychometric effects on user-perceived experiences in an immersive VR environment. Thirty-nine participants experienced three variants of the VR SG using Oculus Rift- S. Participants in the control condition were exposed to the VR with no wayfinding cues, and the experimental groups were exposed to VR with static and dynamic wayfinding cues. Results showed that VR SG with wayfinding cues induced less tension, challenge, and negative affects in users’ overall perceived experience. Similarly higher positive affects were observed for the experimental groups with wayfinding cues. It was interesting to observe that there were no significant effects of wayfinding on competence, flow, and immersion; however, heart rate was significantly high in the control group. These findings suggest that wayfinding cues can promote the users perceived quality of experience in the VR.
