Ludic games and gamification processes can extend functional skills in players as they integrate different intelligences and stimulate the cognitive, perceptual, and motor activities. Play can facilitate the work of occupational therapist since provides better cooperation of the patient, besides helping in its development, increasing its behavioral repertoire, mainly in the accomplishment of activities of daily living. This chapter addresses these issues, discussing the design of a gamified virtual environment that helps occupational therapists to develop the potential of children and adolescents with mild, moderate, and severe neuropsychomotor disorder. For that, the authors present an investigation of the use of a gamified virtual environment and interaction devices in the training of activities of daily living. As result, they note that games as assistive technology can encourage the integration of education, rehabilitation, and habilitation of people in situations of vulnerability and social risk, providing access and inclusion through playful and challenging activities.

Model Development Process

This paper describes a new technique for synthesizing realistic sounds for virtual environments. The four-phase technique described uses wavelet analysis to create a sound model. Parameters are extracted from the model to provide dynamic sound synthesis control from a virtual environment simulation. Sounds can be synthesized in real time using the fast inverse wavelet transform. Perceptual experiment validation is an integral part of the model development process. This paper describes the four-phase process for creating the parameterized sound models. Several developed models and perceptual experiments for validating the sound synthesis veracity are described. The developed models and results demonstrate proof of the concept and illustrate the potential of this approach.

Domain Specific

Few production virtual environment (VE) applications involve complex three-dimensional (3D) interaction. Our long-term collaboration with architects and engineers in designing 3D user interfaces (3D UIs) has revealed some of the causes: existing interaction tasks and/or techniques are either too generic when isolated from the application context, or too specific to be reusable. We propose a new design approach called domain-specific design (DSD) that sits between the generic and specific design approaches, with an emphasis on using domain knowledge in 3D interaction techniques. We also describe an interaction design framework encompassing generic, domain-specific, and application-specific interaction tasks and techniques. This framework can be used by designers to think of ways to produce domain-specific interaction techniques. We present a particular DSD method, and demonstrate its use for the design of cloning techniques in a structural engineering application. Results from empirical studies demonstrate that interaction techniques produced with domain knowledge in mind outperformed other techniques by improving task efficiency, work flow, and usefulness of the 3D UI.

Spatially Distributed

Walk-in Theater is a portable virtual cinema for the display of spatially distributed multichannel movies (“walkies”). The miniature experience engages participants’ proprioceptors and spatial memory, allowing them to orient themselves as they navigate a field of scattered video streams and localized sounds reproduced on a handheld computing device. Departing from one-way linear cinema played on a single rectangular screen, this multichannel virtual environment pursues a cinematic paradigm that undoes habitual ways of framing things, employing architectural concepts in a polylinear-video polyphonic-sound construction to create a kind of experience that lets the world reveal itself and permits discovery on the part of beholders. Interaction design for Walk-in Theater supports approaches to cinematic construction that employ the ambulatory, multiple and simultaneous viewpoints that humans exercise in everyday life.

<p>Candi Prambanan sebagai warisan budaya yang diakui UNESCO, tetapi muncul masalah pelapukan batuan karena banyaknya pengunjung. Jumlah pengunjung perlu diatur, salah satunya dengan implementasikan dalam bentuk aplikasi Prambanan VR. Virtual Reality (VR) mengalami pertumbuhan karena dapat dijalankan pada perangkat mobile yang siap pakai, dengan harga terjangkau. Namun, interaksi masukan hanya terbatas pada penggunaan head tracking atau tombol input, dan sulit untuk melakukan tugas rumit seperti navigasi dengan berjalan terutama pada lingkungan VR yang luas, tetapi lingkungan nyata terbatas.  Penelitian ini membandingkan tiga metode interaksi saat bernavigasi di lingkungan VR yang luas, yaitu dengan dengan teknik non-alami (gamepad), teknik semi-alami berdasarkan posisi kepala (Head-Tilt), dan teknik alami dengan metode jalan di tempat (WIP). Penelitian ini juga menganalisis bentuk interaksi yang dapat meminimalkan sakit akibat penggunaan aplikasi VR (cybersickness). Pengujian teknik navigasi di lingkungan virtual dengan aksi berjalan seperti di dunia nyata dilakukan untuk menemukan bentuk interaksi yang lebih realistis yang dapat meningkatkan kinerja pengguna dan tetapi meminimalisir sakit yang timbul, saat menyelesaikan tugas bernavigasi. Survei efek sakit yang timbul dilakukan menggunakan kuesioner simulator (SSQ), dan hasil eksperimen menunjukkan bahwa pengalaman yang mendalam (immersive) akan dicapai saat interaksi yang dirasakan oleh pengguna menyerupai aksi berjalan secara alami dapat disediakan di lingkungan virtual, yaitu WIP.  Walaupun teknik ini muncul jeda saat bernavigasi, dan lambat serta kurang akurat dibandingkan kedua teknik lainnya, namun menghasilkan tingkat cybersickness minimal.</p><p> </p><p>Abstract</p><p>Prambanan temple is listed as UNESCO World Heritage Sites, but the problem of stones corrosion due to the large number of visitors. Need to split the visitors, one of them by implementing in Prambanan VR application. Virtual Reality (VR) is growing fast because can run on mobile devices which ready and affordable. However, mobile VR inputs are limited to the use of head tracking or input keys, and difficult to perform complex tasks such as navigating by walking on a large virtual environment, in limited real environment. This study compared three interaction techniques for navigating in large virtual environment, with non-natural techniques (gamepad), and semi-natural techniques based on head-tilt, and natural navigation using walk-in-place (WIP). This study also analyzes which interactions could minimize the cybersicknes. This navigation techniques are tested in virtual environments with approach real-world walking action, to found a more realistic interaction design that can increase the performance of user tasks and minimalize motion sickness, when navigating. The survey was conducted using a simulator sickness questionnaire (SSQ), and the experimental results show that an immersive experience is achieved when there is an interaction likes real walking action provided in a virtual environment. Although, the WIP shows delayed and slower also less accurate than the other techniques, navigation interaction with the WIP method results minimal cybersickness.</p>

New Generation

Virtual Environment (VE) is an artificial environment created for providing the information in Virtual Reality (VR). The audiences are able to obtain the information via interaction to the environment. Virtual Reality for Culture heritage buildings, which are inherited from past generations and maintained in the present, is an interested topic because its contents often built for giving the information and knowledge about the past to the new generation in virtual museums. However, there is a limitation of Virtual Reality (VR) applications in reproducing cultural sites as most of these applications are not successful in catching public’s attention and involvement. In this research, we focus on using Natural Interaction (NI) interfaces based on a body movement in Virtual Reality for museums to grab attention from audience and to increase public’s involvement. This paper presents the development of Natural Interaction using Microsoft Kinect to define the new grammar of gesture for Sino Portuguese Architecture which is a cultural heritage of Thailand. Results of early tests improved the prototype in progress which alllows more complexity in natural interchanges and connection between users and virtual world. The final result was evaluated after the system was installed in Peranakannitat museum and by interviewing 6 docents. It was found that our system was easy to use as it took only about 3 - 5 min to familiarize the system for navigation in the virtual environment without recognizing the grammar of gesture commands.
