In the Kantian model, the sublime oscillates between the mathematical sublime—emphasizing the vastness of nature that exceeds the comprehension of the viewer—and the dynamic sublime, in which the viewer attempts to establish a sense of control over nature. In big data visualization based on the sublime, users tend to apprehend the magnitude of data from a distance, provoking an experience of fear or awe over the immense scale of technology. Such a model is predicated on a dualism between body and data. In contrast to Kantian dualism, Taoist philosophy privileges the integration of data, body, and nature. This article theorizes the Taoist body in relation to digital technology by, firstly, critiquing the Kantian sublime that underpins much data visualization. Visualization based on Taoist

Conventional physical rehabilitation relies on professional trainers, equipment, and facilities, which are time-consuming and expensive for users. It often reduces the users’ motivation to perform exercises. It can be difficult for users to continue their physical rehabilitation through the conventional model. However, recent studies demonstrate that serious games have the potential to improve the effectiveness of rehabilitation training through a more engaged and immersive game design. Most of those studies focus on technology and the development of a specific MoCap sensor-based SG design for users with motor deficiencies, rather than emphasizing the users’ experience impacting the effect of performance in physical rehabilitation. This study developed a prototype of a physical rehabilitation exercise game that considers user experience. This game employs a wearable inertial MoCap sensor enabling users
to interact intuitively with the game to promote physical activities for health. We analyze and discuss user satisfaction and game experience through user experience questionnaires. The results suggest that most users were satisfied with the SG-based rehabilitation, and found the game was enjoyable and engaging. Based on the implications, we discuss possible future research to improve user experience of the highly accurate
real-time MoCap-based serious game. This can enable users with motor disabilities to undertake physical exercises in a home environment.

An effective way to reduce injuries or death during a fire is to improve human evacuation behavior. Many studies have demonstrated that behavioral skills training can effectively help people of different ages to acquire safety skills for emergencies. Based on virtual reality (VR), serious games (SGs) and behavioral skills training (BST), this study proposes a theoretical model of “VRSG-BST” as a fire safety training method. Elderly people in care facilities were selected to evaluate the proposed model because their lack of knowledge on fire safety and the associated potential health problems increase the likelihood that they
will become victims in a fire. It is expected that engagement and immersion in the SG can improve the elderly’s learning performance in fire skills and enhance their interest and sense of fun experienced during fire safety training. The SG could effectively improve the skills of evacuation in an emergency. Hence, this study conducts two parallel investigations: 1) it
compares fire safety behavior of the elderly between an experimental and a control group, and 2) it determines the effects of BST for fire safety by comparing only the experimental group in pre- and post-BST phases. The study adopts in situ training (IST) to evaluate the acquisition of knowledge and skills during the experimental stage. The outcomes of the study provide suggestions and guidelines for VR-SG design in the practice of BST.

Defined variously by early and contemporary writers, yijing links an artist's emotional domain to objects in the world. This article conceptualises yijing as an ecological aesthetics and distinguishes it from an environmental aesthetics. In particular, two aspects of yijing render it an eco-aesthetics: subject-object correspondence (or 'engagement'); and empathic identification with the environment (or 'bio-empathy'). Three brief case studies from urban planning, environmental conservation and the creative arts demonstrate the contemporary importance of yijing to ecological issues.
