    In the period of 2009-2018, Indonesia experienced an increase in international tourist arrivals. However, the number of foreign tourists in Indonesia is still relatively small when compared to other countries. In ranking, Indonesia is ranked 5. The Indonesian government through the Ministry of Tourism has prioritized tourism development in 10 places that have good potential similar to Bali called "The New Bali 10", one of which is Mount Bromo tourism. In 2019 compared to 2018 the number of tourists decreased. In accordance with the vision of the Ministry of Tourism, which is to do marketing oriented to tourists, virtual tour technology is used to promote Mount Bromo tourism objects which are expected to increase user interest. The Mount Bromo virtual tour was developed using the A-Frame framework and using the MDLC (Multimedia Development Life Cycle) model as a multimedia development model. The TAM (Technology Acceptance Model) model is used as a method of accepting new technology to users. The final results will also be compared between the TNBTS official website (Bromo Tengger Semeru National Park), webVR 360 photos, and webVR video 360 as promotional media. Based on the results of effectiveness testing, webVR video 360 is the most effective media to increase user interest with an effectiveness of 83.4%. Technology acceptance testing using the TAM (Technology Acceptance Model) model that has been carried out also shows that webVR video 360 media has better technology acceptance with positive and significant hypotheses reaching 6 hypotheses than other promotional medi

    Recently, telemedicine has been widely applied in remote diagnosis, treatment and counseling, where the Internet of Things (IoT) technology plays an important role. In the process of telemedicine, data are collected from remote medical equipment, such as CT machine and MRI machine, and then transmitted and reconstructed locally in three-dimensions. Due to the large amount of data to be transmitted in the reconstructed model and the small storage capacity, data need to be compressed progressively before transmission. On this basis, we proposed a lightweight progressive transmission algorithm based on large data visualization in telemedicine to improve transmission efficiency and achieve lossless transmission of original data. Moreover, a novel four-layer system architecture based on IoT has been introduced, including the sensing layer, analysis layer, network layer and application layer. In this way, the three-dimensional reconstructed data at the local end is compressed and transmitted to the remote end, and then visualized at the remote end to show reconstructed 3D models. Thus, it is conducive to doctors in remote real-time diagnosis and treatment, and then realize the data processing and transmission between doctors, patients and medical equipment

    With the arrival of the Web 2.0 era and the rapid development of virtual reality (VR) technology in recent years, WebVR technology has emerged as the combination of Web 2.0 and VR. Moreover, the concept of “WebVR + medical science”is also proposed to advance medical applications. However, due to the limited storage space and low computing capability of Web browsers, it is difficult to achieve real-time rendering of large-scale medical vascular models on the Web, let alone large-scale vascular animation simulations. The framework proposed in this paper can achieve virtual display of the medical blood vasculum, including lightweight processing of the vasculum and virtual realization of blood flow. This innovative framework presents a simulation algorithm for the virtual blood path based on the Catmull-Rom spline. The mechanisms of progressive compression and online recovery of the lightweight vascular structure are further proposed. The experimental results show that our framework has a shorter browser-side response time than existing methods and achieves efficient real-time simulation
