Study of Smart Watch Interface Usability Evaluation Based on Eye-Tracking

Nowadays the intelligence of watches brings users brand new experience, and at the same time it makes human-watch interaction relationship becomes more and more complicated, therefore the design of smart watch interface faces greater challenge. As the interface of smart watches delivers more and more information, how to guarantee favorable usability of smart watch interface becomes the focus of designers. Designers need more objectively evaluate the reasonableness of smart watch interface layout and the visibility of interface elements. But traditional evaluation indexes can’t intuitively reflect whether the system structure conforms to the thinking mode of users; and traditional evaluation indexes can’t reveal the strategies employed on interface by users.

Analysis on Universality Evaluation Standard System of Product Design on Basis of Kansei Engineering and Virtual Reality

The universality evaluation standard system of product design on basis of Kansei Engineering and virtual reality constructed in this paper will effectively solve the current practical problems of product design evaluation to the greatest degree. The reasons why people are usually at a loss when conducting product design evaluation are that, on the one hand they do not know what kind of method or means is able to achieve the goal of scientific evaluation, and on the other hand whether there is or what kind of method and model among hundreds of product design evaluation methods and models can deal with the design evaluation problem of this product.This paper aims to carry out in-depth research from the following four aspects. (1) Systemically combing the product design evaluation research results which include Kansei engineering, virtual reality, and cross-over research results of product design evaluation. (2) Scientifically summarizing the construction elements of product design universality evaluation standard system. (3) Scientifically refining construction factor and correlation factor, and extracting universality standard construction factor through researches on comparison of construction factor and correlation factor. (4) Setting priority standard through researches on the reasonable and matched priority relation of various standard construction factors, and finally constructing a product design universality evaluation standard system on basis of Kansei Engineering and virtual reality.

Study on "Intuitive Semantics" of Orient Traditional Creation Wisdom Contained in the Design of Modern Mechanical Products

The traditional mechanical products have been considered to be structured products all the time. The concept of “priority to function” dominates the design philosophy in the long term, but it unilaterally stresses “technique” and “performance” of the “product” but overlooks “emotion” and “care” of “human”, thus making the relationship between “human” and “product” “disharmonious” and violating the original intention of human for creation. Then this requires us to think deeply. In the aspect of things perception in China, starting from characters invention by Cang Jie, there were cultural heritages being good at abstraction including “intuitive realization”, “sudden enlightenment” and “empathizing and understanding” since ancient times. The six methods of character creation reflect the “intuitive semantics” or the information referred to as “intuitive semiology” formed very early in Chinese culture. The theoretical achievements of domestic and overseas mechanical product design are presented and analyzed firstly in this essay; and then starting with the study on Chinese traditional creation culture and practical activities, the orient traditional creation wisdom that contains substantial thinking and elements related to “intuitive semantics” will be researched; finally, the “intuitive semantics” will be infused into design of modern mechanical products to think and study and survey the relationship between human emotion and technical principles, thus perfecting the innovation theory of modern mechanical product design.

The Study of Modern Emergency Products under the Direction of New Ergonomics

The rapid development of computer and internet technology has led to human beings’ society into the era of information, and brought certain influence on the modern design and innovative design. Moreover, product design is now emphasizing on design ideology such as Humanisms, Culture and People-Oriented design. That is products serving for users and all their shapes, function, color, material and structure showing the respect and care for their users, furthermore, they are endeavoring in providing some virtual using experience including Humanities, History, Emotion, Joviality and Security. Recently, natural disasters such like earthquake, snowstorm, fire, typhoon, flood and drought always cost enormous casualties and economic loss. As a result of the government’s popularization and promotion of disaster prevention and rising awareness of the meaning of safety, emergency products come up to exist in our daily life. However, emergency indications would send people a sense of fear, which should lower their life quality. New ergonomic, mainly based on researching methods as Physiology, Psychology and Anthropometry etc., and gives prominence to some interdisciplinary subjects, for example, Social Psychology and Economics etc. It is focusing on service system and ergonomic issues. On the topic of disaster emergency design, this paper suggests three researching methods for it: PDCA model, Quantitative Analysis, Semantic Differential. Then how could Emergency Products produce high life quality? The essay records the researching theorization which has been used before. They are based on the people-oriented ideology, through in four phases of the establishment of the design goals (design target selection and judgment), the preliminary design (understanding and analysis of the design goals, design concept engineering), deep design (product detail design) and design confirmation (completion of the design goals) to practice and research.

Constructing Li3VO4 nanoparticles anchored on crumpled reduced graphene oxide for high-power lithium-ion batteries

Li3VO4 is considered to be one of the most promising anode materials for lithium-ion batteries (LIBs) because of its outstanding safety performance and energy density. In this manuscript, hollow and spherical Li3VO4/crumpled reduced graphene oxide (LVO/CRGO) nanocomposites were formed by one-step and continuous spray pyrolysis with no need for further treatment. In this high-temperature gas phase process, the precursors of Li and V undergo a rapid chemical reaction, resulting in LVO nanoparticles anchored on the surface of graphene oxide. At the same time, the graphene oxide flakes are crumpled and reduced due to the droplet evaporation and a high-temperature reducing atmosphere in the reaction zone. The special three-dimensional (3D) architecture constructed by RGO sheets is beneficial for electrochemical performance owing to its preferable mechanical strength and superior electrical conductivity. When used as an anode, the LVO/CRGO nanocomposite exhibits extraordinary cycling and rate performance. It delivers an outstanding specific capacity of 487.5 mA h g−1 at 0.2C with less than 2% decay over 100 cycles. After 80 cycles at various specific currents from 0.1 to 60C, as the rate returned to 0.1C, the 5th specific capacity returns to 452.4 mA h g−1. Meanwhile, compared with general multiple-step methods, the one-step continuous spray pyrolysis method offers a facile, efficient and high-yielding alternative, which is meaningful and has potential in synthesizing other CRGO-based anode materials for LIBs.

Applying Intuitive Thinking in Smart Home Design Based on Semantic Association

With the advance of Industry 4.0, the merging of automation and information has become an important trend of product design. Smart home products are increasingly valued and favored by consumers. However, the existing smart home product design mainly focuses on the product performance and technology sense and often ignores the users’ emotional and spiritual needs, which may increase the users’ cognitive difficulty and reduce users’ satisfaction. Good products should not only meet the needs of usage, but also to take the user’s psychological factors into consideration, accordingly to enrich the emotional experience of users. Household products are closely related to the users’ life. When using the household products, users are more likely to use the visual intuitive thinking mode, thereby giving the product a special emotional meaning. This paper takes the innovation design of water equipment in kitchen as an example. After fully understanding the users’ imaging and description about the future kitchen, it extracts key words such as “cleanness” that the users generally think can represent the future kitchen, to guide the user to start the semantic association and establish the users’ semantic schema. Also, this paper uses the Evaluation Grid Method (EGM) to link the images produced by intuitionistic association with the design elements of products, and put forward the product design principles in line with the users’ intuitive thinking to establish a product design framework based on semantic association. By testing the concept design product in practice, it proves that this framework can improve the users’ satisfaction with the product. This paper proposes that the product design process should take full account of human factors, and that the users’ intuitive thinking habits should be applied to product design, which provides a reference for innovative design of smart home products.

Analysis of Intuitive Thinking in Five-Sense Design: An Example of Auditory Design

Intuitive thinking is a creative way of thinking based on perception. Through mobilizing the knowledge and experience people already mastered, it can help human brain produce the hypothesis or image of the whole property and law of things quickly. In product design, the correct use of intuitive thinking can not only help designers to enhance the imagination and creativity, improve the level of design, but also make products more humane and associated with the user experience, thereby it will greatly reduce the learning costs and bring a better user experience.
