System Effectiveness

User experience has a significant impact on the effective product design and improvement, especially for a personalized product to meet user’s individual need. The development of personalized products requires data from user experience in the evaluation of the product function and performance. The existing methods of Internet-based interactive platforms and direct market user surveys cannot provide users full experience of product features. This research proposes a user interactive system based on virtual reality technologies to provide users a close-real experience in the development of open-architecture products. The system provides users an interface built on the virtual environment. The users can review a product design by virtually operating and evaluating the product. The system records users’ operations and feedbacks for designers to improve the product. Food trucks designed using the open-architecture concept are used as applications to verify the proposed method. A user survey is conducted to examine the system effectiveness.

Aimed at the problem of how to objectively obtain the threshold of a user’s cognitive load in a virtual reality interactive system, a method for user cognitive load quantification based on an eye movement experiment is proposed. Eye movement data were collected in the virtual reality interaction process by using an eye movement instrument. Taking the number of fixation points, the average fixation duration, the average saccade length, and the number of the first mouse clicking fixation points as the independent variables, and the number of backward-looking times and the value of user cognitive load as the dependent variables, a cognitive load evaluation model was established based on the probabilistic neural network. The model was validated by using eye movement data and subjective cognitive load data. The results show that the absolute error and relative mean square error were 6.52%–16.01% and 6.64%–23.21%, respectively. Therefore, the model is feasible.

This article presents the ongoing development and testing of a “shared realities” computational workflow to support iterative user-centered design with an interactive system. The broader aim is to address the challenges associated with observing and recording user interactions within the context of use for improving the performance of an interactive system. A museum installation is used as an initial test bed to validate the following hypothesis: by integrating three-dimensional depth sensing and virtual reality for interaction design and user behavior observations, the shared realities workflow provides an iterative feedback loop that allows for remote observations and recordings for faster and effective decision-making. The methods presented focus on the software development for gestural interaction and user point cloud observations, as well as the integration of virtual reality tools for iterative design of the interface and system performance assessment. Experimental testing demonstrates viability of the shared realities workflow for observing and recording user interaction behaviors and evaluating system performance. Contributions to computational design, technical challenges, and ethical considerations are discussed, as well as directions for future work.

Hazard investigation education plays a crucial role in equipping students with adequate knowledge and skills to avoid or eliminate construction hazards at workplaces. With the emergence of various visualization technologies, virtual photoreality as well as 3D virtual reality have been adopted and proved advantageous to various educational disciplines. Despite the significant benefits of providing an engaging and immersive learning environment to promote construction education, recent research has also pointed out that virtual photoreality lacks a 3D object anatomization tools to support learning, while 3D-virtual reality cannot provide a real-world environment. In recent years, research efforts have studied virtual reality applications separately, and there is a lack of research integrating these technologies to overcome limitations and maximize advantages for enhancing learning outcomes. In this regard, the paper develops a construction hazard investigation system leveraging object anatomization on an Interactive Augmented Photoreality platform (iAPR). The proposed iAPR system integrates virtual photoreality with 3D-virtual reality. The iAPR consists of three key learning modules, namely Hazard Understanding Module (HUM), Hazard Recognition Module (HRM), and Safety Performance Module (SPM), which adopt the revised Bloom’s taxonomy theory. A prototype is developed and evaluated objectively through interactive system trials with educators, construction professionals, and learners. The findings demonstrate that the iAPR platform has significant pedagogic methods to improve learner’s construction hazard investigation knowledge and skills, which improve safety performance.

In order to solve the problem of lack of immersion in the MOOC curriculum, through research on key technologies, a MOOC teaching interactive system based on virtual reality was constructed to improve it. Through the decompo-sition of complex objects or the addition of blank sub-objects, the system built corresponding collision detectors to achieve more realistic collision de-tection effects. The immersive and interactive nature of the virtual user in the virtual scene was enhanced. The results showed that the system used the immersive, interactive and constructive sense of virtual reality to build peo-ple's interest in learning. Therefore, the MOOC teaching interactive system based on virtual reality has a good sense of immersion, interaction and con-ceivability.
