This study investigated the impact of two In-Vehicle Information Systems (IVISs) on both usability and driving safety. We simulated vehicle checkerboard and hierarchical IVIS interface layouts and examined their usability based on task completion time, error rate, NASA-TLX, and System Usability Scale (SUS). Our driving safety measures included mean glance time, mean number of glances, blink frequency,...
Design sketch is at the core of the product design process. How to use design sketch to express design concepts and develop creative thinking, is the key point in design sketch teaching. Firstly, the definition, classification and function of design sketch are explained. Secondly, its importance in the product design process is analyzed. Then design sketch is compared with computer rendering. The...
A 3D shape blending based approach for product form design is addressed in this article. Different from traditional CAD tools, this method is not for design express but a tool can be used to stimulate designer's inspiration and assist in creative design of product shape. New shapes can be generated by blending two different product models into new ones automatically and by doing further treatment...
With the rapid development of economy in China and the acceleration of people's living pace, Chinese fast food came into a new stage of fast development. However, the western fast food holds most part of the market, and the situation about the development of Chinese fast food becomes even worse. Especially the tableware of Chinese fast food in present market, which can't embody the characteristic...
Shape blending is of great theoretical and practical significance in industrial design, engineering simulation, etc. An approach to 3D shape blending using point cloud slicing is proposed in this article. It can be used in industrial design as an aid to design creativity. After the uniform slicing of each point cloud model, an improved ray-firing method is adopted to establish the correspondence between...
This paper carried out research on sketch of conceptual design. Through deriving the semantic of different strokes and perspective projection in the sketch, the creation of design was recorded, analyzed and comprehended. The indistinct novel information of sketch then could be translated into useful information for backend engineering design. As an enhancement and extension of previous methods and...
