And the judgment and recognition of product material often remain on the rendering effect drawings of the 2D display. However, it cannot fully intuitive performed, even sometimes cannot identify the specific material composition. As a device to simulate the real environment, VR strengthens people’s immersive experience by its 3D sense of space. The purpose of this study is to explore whether the material perception in VR is different from that in traditional 2D mode, and to determine whether VR can be used as a tool for users’ material perception in the future. The study found that VR provides the users with stereoscopic visual effects not seen on a 2D display. This feature seems to deepen the perception of material, which may facilitate the design of industrial products, furniture design, automotive interior and so on.

The study is carried out in two heritage sites in Suzhou, which itself is a historical city located in the south of Yangtze River in China. Ethnographic methods are used to explore and collect the data. Service design thinking principles and methods are then applied to analyze the observed service businesses and identify common thematic issues and design opportunities. Service prototyping techniques are also used to review and rearrange a customer’s journeys in the services. The result shows that modern design thinking concepts such as the user-centered approach can provide fundamental transformations to those services. It also illustrates a more cross-cultural development with the cross-cultural encounter between the modern design techniques and the traditional culture-based services.

The immersive and interactive experience of VR fits seemingly well with practical subjects such as Creative Design. Design-related courses in secondary education usually appeal to the students with their practical elements, which also help in developing a student's creative and cognitive ability. The dual coding learning theory states that the learning process can be improved by using the symmetrical visual and language systems of the left and right hemispheres. This paper presents a novel teaching framework that combines classroom learning with VR technology. We devise the course structure based on Bloom’s Taxonomy and fill in knowledge and skills related to 3D Design. In collaboration with a local school, we implemented and delivered the proposed course to a group of students. After the course, we use ques...

However, it is very challenging to create this by general people. In this paper, we propose an interactive and generative approach to automatically generate the Chinese Shanshui painting documents based on users' input, where the users only need to sketch simple lines to represent their ideal landscape without any professional Shanshui painting skills. This sketch-to-Shanshui translation is optimized by the model of cycle Generative Adversarial Networks (GAN). To evaluate the proposed approach, we collected a large set of both sketch data and Chinese Shanshui painting data to train the model of cycle-GAN, and developed an interactive system called Shanshui-DaDA (i.e., Design and Draw with AI) to generate Chinese Shanshui painting documents in real-time. The experimental results show that this system can generate satisfied Chinese Shanshui painting documents b...

The characteristics of the product users are as important as the design features for products that might alter the appearances of these users. This paper proposes a product evaluation scheme that integrates design features and user facial characteristics in one evaluation process. We implement an experimental scheme to evaluate the design prototype of glasses frames. 3D scanning technology is applied to capture the facial features of users and reconstruct realistic 3D face models. Those allow us to post-process individual facial feature without changing the others. In the experiment, the subjects response on three affective measures related to personality attributes: confidence, friendliness, and attractiveness, signified by the faces wearing the factorized glasses frames. The results show that changing certain design features indeed influences the impressions of the faces with varied facial characteristics. Th...

The customized design space is derived from the 3D scanning models. Based on the finite element analysis, the structural framework is determined through topology optimization with allowable strength. By means of generative design, the lattice library is constructed to fill the frames under different conformal algorithms. Finally, the proposed method is illustrated by the exoskeleton design case.

This paper proposes an experimental evaluation scheme that investigates the interactions between the design features of 3D eyeglasses frames and user facial characteristics. Face models of users containing both geometric and image data were constructed using 3D scanning. A face deformation method was developed to manipulate individual facial features without changing the other features on the face models. In the evaluation scheme, participants judged synthetic faces, which had varied eye distances and orientations and were wearing factorized eyeglasses frames, according to three affective measures related to the personality attributes of confidence, friendliness, and attractiveness. The experimental results show that changing certain design features influences the impressions of the face models with varied facial characteristics. The proposed scheme facilitates designing products that strengthen the impression of specific personality traits by accommodating individual differences in facial features.
