To evaluate ubiquitous computing technologies, which may be embedded in the environment, embedded in objects, worn, or carried by the user throughout everyday life, it is essential to use methods that accommodate the often unpredictable, real-world environments in which the technologies are used. This article discusses how we have adapted and applied traditional methods from psychology and huma...

Yuan and Chan (Psychometrika, 76, 670-690, 2011) recently showed how to compute the covariance matrix of standardized regression coefficients from covariances. In this paper, we describe a method for computing this covariance matrix from correlations. Next, we describe an asymptotic distribution-free (ADF; Browne in British Journal of Mathematical and Statistical Psychology, 37, 62-83, 1984) me...

The use of Cloud Computing has increasedrapidly in many organization .Cloud Computing provides many benefits in terms of low cost and accessibility of data. In addition Cloud Computing was predicted to transform the computing world from using local applications and storage into centralized services provided by organization.[10] Ensuring the security of Cloud Computing is major factor in the Clo...

grid computing is a term referring to the combination of computer resources from multiple administrative domains to reach a common computational platform. mobile computing is a generic word that introduces using of movable, handheld devices with wireless communication, for processing data. mobile computing focused on providing access to data, information, services and communications anywhere an...

Web Intelligence deals with the scientific research and development to explore the fundamental roles as well as practical impacts of soft computing and advanced intelligent paradigms for the next generation of Web-based systems, services, and environments. Chance discovery means discovering chances — the breaking points in systems, the marketing windows in business, etc. It involves determining...

Although central to human development and functioning, emotions have, until recently, had somewhat marginal status in scientific disciplines in general and have been largely ignored in the more applied settings such as human factors. Over the past 10 years however, research in emotion in both psychology and neuroscience has established that emotion is intricately linked with what has been tradi...

Tangible computing incorporates gesture, grasping, and the use of physical objects as integral parts of interaction design. This paper describes a theory-driven design studio course in which students were asked to develop a new tangible application grounded in the psychology of gesture and thought and informed by protocol studies and critiques of the role of gesture in existing tangible applica...
