Earth science also known as geoscienceis an inclusive term for all sciences related to Earth geology, meteorology, oceanography, etc. Although environmental and earth science cover essentially the same material, environmental science places greater emphasis on the biological realm, while earth science places greater emphasis on the physical realm.
Methodologies[ edit ] A number of diverse methodologies outlining techniques for human—computer interaction design have emerged since the rise of the field in the s.
Most design methodologies stem from a model for how users, designers, and technical systems interact. Early methodologies, for example, treated users' cognitive processes as predictable and quantifiable and encouraged design practitioners to look to cognitive science results in areas such as memory and attention when designing user interfaces.
Modern models tend to focus on a constant feedback and conversation between users, designers, and engineers and push for technical systems to be wrapped around the types of experiences users want to have, rather than wrapping user experience around a completed system.
Activity theory provides a framework to reason about actions in these contexts, analytical tools with the format of checklists of items that researchers should consider, and informs design of interactions from an activity-centric perspective.
Users, designers and technical practitioners work together to articulate the needs and limitations of the user and create a system that addresses these elements.
Often, user-centered design projects are informed by ethnographic studies of the environments in which users will be interacting with the system.
This practice is similar to participatory designwhich emphasizes the possibility for end-users to contribute actively through shared design sessions and workshops.
Principles of user interface design: VSD uses an iterative design process that involves three types of investigations: Conceptual investigations aim at understanding and articulating the various stakeholders of the technology, as well as their values and any values conflicts that might arise for these stakeholders through the use of the technology.
Empirical investigations are qualitative or quantitative design research studies used to inform the designers' understanding of the users' values, needs, and practices.
Technical investigations can involve either analysis of how people use related technologies, or the design of systems to support values identified in the conceptual and empirical investigations.
Before a display is designed, the task that the display is intended to support must be defined e.
A user or operator must be able to process whatever information that a system generates and displays; therefore, the information must be displayed according to principles in a manner that will support perception, situation awareness, and understanding.
Thirteen principles of display design[ edit ] Christopher Wickens et al. A reduction in errors, a reduction in required training time, an increase in efficiency, and an increase in user satisfaction are a few of the many potential benefits that can be achieved through utilization of these principles.
Certain principles may not be applicable to different displays or situations. Some principles may seem to be conflicting, and there is no simple solution to say that one principle is more important than another.
The principles may be tailored to a specific design or situation. Striking a functional balance among the principles is critical for an effective design. Make displays legible or audible.
A display's legibility is critical and necessary for designing a usable display.The focus of the inquiry is on the organization and the dynamics generated by the complex interaction of systems embedded in other systems and composed by other systems.

SIGCHI is the world's largest association of professionals who work in the research and practice of computer-human interaction. What brings us together is a shared understanding that designing useful and usable technology is an interdisciplinary process, and when done properly it has the power to transform persons' lives.
The Digital Systems Interaction concentration focuses on the educational and interactive applications needed by an organization and the improvement of the user’s interaction with those applications.
This concentration works on Interaction Design and Instructional Technology, which involves the practice of designing interactive digital products, environments, systems, and.
