Book Description
Workers performing sedentary tasks in job types such as administrative, technical, customer service and executive could be seated for four or more hours during their normal work shift. Due to the prolonged periods of sitting, a worker could experience dissatisfaction, discomfort and fatigue, which could lead to reduced performance. Symptoms of discomfort could over time lead to injuries and illnesses such as low back pain, cumulative trauma disorders, disc herniation, and pressure ulcers. It is understood that posture and support affect discomfort and consequently have received wide spread attention from researchers. Another factor that could contribute to discomfort is the thermal influence of the seating surface. A common observation is that after a certain duration of sitting, the person starts to feel uncomfortable and tends to make small movements in the chair. These small movements are the human body's response to either relieve pressure at the ischial tuberosities or a thermoregulatory response (i.e. the body is trying to dissipate heat that was built up at the skin or clothing interface) or both. The primary focus of this research was to investigate the interactions of human-seat interface temperature on a user's discomfort while performing a typing/mousing/reading task on different combinations of seat cushion materials for two sitting durations. A total of five seat pans with different combinations of cushion materials were used. Objective measures and subjective measures on 10 females were collected for a 5-minute sitting duration and a 3 hour sitting duration. The objective measure was temperature and subjective measures included ASHRAE Scale, Body Discomfort Map and Shackel Scale. The results indicated that different combinations of seat cushion materials and sitting durations had an impact on the human-seat interface temperature. Furthermore, correlation between interface temperature and subjective ratings of comfort were found, which could aid designers in the selection of a combination of seat pan cushion materials.

Book Description
The study of human body measurements on a comparative basis is known as anthropometrics. Its applicability to the design process is seen in the physical fit, or interface, between the human body and the various components of interior space. Human Dimension and Interior Space is the first major anthropometrically based reference book of design standards for use by all those involved with the physical planning and detailing of interiors, including interior designers, architects, furniture designers, builders, industrial designers, and students of design. The use of anthropometric data, although no substitute for good design or sound professional judgment should be viewed as one of the many tools required in the design process. This comprehensive overview of anthropometrics consists of three parts. The first part deals with the theory and application of anthropometrics and includes a special section dealing with physically disabled and elderly people. It provides the designer with the fundamentals of anthropometrics and a basic understanding of how interior design standards are established. The second part contains easy-to-read, illustrated anthropometric tables, which provide the most current data available on human body size, organized by age and percentile groupings. Also included is data relative to the range of joint motion and body sizes of children. The third part contains hundreds of dimensioned drawings, illustrating in plan and section the proper anthropometrically based relationship between user and space. The types of spaces range from residential and commercial to recreational and institutional, and all dimensions include metric conversions. In the Epilogue, the authors challenge the interior design profession, the building industry, and the furniture manufacturer to seriously explore the problem of adjustability in design. They expose the fallacy of designing to accommodate the so-called average man, who, in fact, does not exist. Using government data, including studies prepared by Dr. Howard Stoudt, Dr. Albert Damon, and Dr. Ross McFarland, formerly of the Harvard School of Public Health, and Jean Roberts of the U.S. Public Health Service, Panero and Zelnik have devised a system of interior design reference standards, easily understood through a series of charts and situation drawings. With Human Dimension and Interior Space, these standards are now accessible to all designers of interior environments.

Book Description
Product Experience brings together research that investigates how people experience products: durable, non-durable, or virtual. In contrast to other books, the present book takes a very broad, possibly all-inclusive perspective, on how people experience products. It thereby bridges gaps between several areas within psychology (e.g. perception, cognition, emotion) and links these areas to more applied areas of science, such as product design, human-computer interaction and marketing. The field of product experience research will include some of the research from four areas: Arts, Ergonomics, Technology, and Marketing. Traditionally, each of these four fields seems to have a natural emphasis on the human (ergonomics and marketing), the product (technology) or the experience (arts). However, to fully understand human product experience, we need to use different approaches and we need to build bridges between these various fields of expertise. Most comprehensive collection of psychological research behind product design and usability Consistenly addresses the 3 components of human-product experience: the human, the product, and the experience International contributions from experts in the field

Book Description
The fundamental function of buildings is to provide safe and healthy shelter. For the fortunate they also provide comfort and delight. In the twentieth century comfort became a 'product' produced by machines and run on cheap energy. In a world where fossil fuels are becoming ever scarcer and more expensive, and the climate more extreme, the challenge of designing comfortable buildings today requires a new approach. This timely book is the first in a trilogy from leaders in the field which will provide just that. It explains, in a clear and comprehensible manner, how we stay comfortable by using our bodies, minds, buildings and their systems to adapt to indoor and outdoor conditions which change with the weather and the climate. The book is in two sections. The first introduces the principles on which the theory of adaptive thermal comfort is based. The second explains how to use field studies to measure thermal comfort in practice and to analyze the data gathered. Architects have gradually passed responsibility for building performance to service engineers who are largely trained to see comfort as the ‘product’, designed using simplistic comfort models. The result has contributed to a shift to buildings that use ever more energy. A growing international consensus now calls for low-energy buildings. This means designers must first produce robust, passive structures that provide occupants with many opportunities to make changes to suit their environmental needs. Ventilation using free, natural energy should be preferred and mechanical conditioning only used when the climate demands it. This book outlines the theory of adaptive thermal comfort that is essential to understand and inform such building designs. This book should be required reading for all students, teachers and practitioners of architecture, building engineering and management – for all who have a role in producing, and occupying, twenty-first century adaptive, low-carbon, comfortable buildings.
