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. If the characters or objects being displayed cannot be discernible, then the operator cannot effectively make use of them. Avoid absolute judgment limits.
Do not ask the user to determine the level of a variable on the basis of a single sensory variable e. These sensory variables can contain many possible levels.
Top-down processing. Signals are likely perceived and interpreted in accordance with what is expected based on a user's experience.
If a signal is presented contrary to the user's expectation, more physical evidence of that signal may need to be presented to assure that it is understood correctly. Redundancy gain. If a signal is presented more than once, it is more likely that it will be understood correctly. This can be done by presenting the signal in alternative physical forms e. A traffic light is a good example of redundancy, as colour and position are redundant. Similarity causes confusion: Use distinguishable elements.
Signals that appear to be similar will likely be confused. The ratio of similar features to different features causes signals to be similar. For example, AB9 is more similar to AB8 than 92 is to Unnecessarily similar features should be removed and dissimilar features should be highlighted.
Mental model principles[ edit ] 6. Principle of pictorial realism. A display should look like the variable that it represents e. If there are multiple elements, they can be configured in a manner that looks like it would in the represented environment.
Principle of the moving part. Moving elements should move in a pattern and direction compatible with the user's mental model of how it actually moves in the system. For example, the moving element on an altimeter should move upward with increasing altitude. Principles based on attention[ edit ] 8. Minimizing information access cost or interaction cost.
When the user's attention is diverted from one location to another to access necessary information, there is an associated cost in time or effort. A display design should minimize this cost by allowing for frequently accessed sources to be located at the nearest possible position.
However, adequate legibility should not be sacrificed to reduce this cost. Proximity compatibility principle. Divided attention between two information sources may be necessary for the completion of one task. These sources must be mentally integrated and are defined to have close mental proximity. Information access costs should be low, which can be achieved in many ways e. However, close display proximity can be harmful by causing too much clutter. Principle of multiple resources. A user can more easily process information across different resources.
Reading assignments cover the conceptual aspects of the course. It is very important for you to keep up with the readings so that you obtain a conceptual understand of topics, which may or may not be covered during class time.
I will not be using class time to simply repeat what's in the book. Class Format and Participation. The course will be a mixture of demonstration, discussion, critiques, and hands-on experiences. Much of the class time will be spent developing materials and applying concepts individually or in groups. You will share the results of your efforts with the class through project demonstrations and presentations.
Topics from the assigned readings will also be discussed in class and you should actively participate in class discussions. We will often critique design homework in class on the day it is due, which is all the more reason to have your homework completed on time.
Come prepared to ask questions and to have questions asked of you! All work done in the class must pertain to the class objectives. All other work is prohibited during the class period. The use of instant messaging and playing of video games is strictly prohibited during the entire class period.
IUPUI police is attendance is mandatory. I take attendance during every class, so please be sure to sign the attendance sheet. Students should demonstrate professional behavior by attending class and actively participating in class activities. Learning Activities. Assignments are due throughout the semester as shown on the tentative course schedule.
The assignments represent a significant portion of your course grade. They are intended to help you learn a variety of software applications and effective design principles.
Most of your homework assignments will be in digital form. It is important for you to keep backup copies of your work and to backup your work frequently.
Disk errors, computer viruses, or accidental erasures can destroy your files so can losing your USB drive. No special considerations will be given if your files are lost and so please take every precaution to protect your work. There will be some portions of class set aside for you to work on these assignments, but you will mainly need to work on your own time.
The assignments are meant to be challenging not overwhelming. Each assignment will have detailed instructions on what you are to turn in on the due date. These may include hard copies, Grades are based on points as indicated below: A Pts. C files submitted to Pts.
A- Pts. D presentation, or a Pts. B Pts.
D- combination. Make sure to Pts. B- 59 and below F read the assignments Pts. O carefully! Assignments not turned in on time will only be accepted within 24 hours, and only for half-credit. There are no exceptions! Any work turned in more than 24 hours late will not be accepted, unless excused for medical reasons or other reasons discussed with me prior to the due date. You are beginning your careers as New Media professionals, so now is the time to develop strong time-management skills.
Many of the assignments will be presented before the class and critiqued. Many of you may have not experienced a critique before, but it's nothing to be afraid of. It is a constructive and positive process where students can discuss each other's work and learn from everyone's successes and mistakes not just your own.
Homework assignments will be posted online and submitted via OnCourse unless specified otherwise. The filename of every assignment must include your name and the title of the assignment. For example, for a Word document containing a project proposal, "jones-proposal.
If you do not label assignments appropriately, the assignment may get lost and you will not receive credit. Make sure you give me the right files!
Three quizzes will be given during class throughout the semester. These help you test your knowledge of the content covered so far. Quizzes cannot be made up.
A midterm and a final exam will be given. The exams will be made up of multiple-choice and short-answer questions. They may also include "hands-on" testing using the computer to make a design. Make-up tests. Make-up tests can only be given if you provide appropriate documentation e. Making up a test for planned absences e. You can also email me at anytime with concerns, assistance outside of class or other issues.
Suggestions for Success in this Course: If you are typing, it should be the notes you are taking. There are always legitimate reasons for missing class. Personal illness, accident, a death or serious illness in the immediate family, athletic trips, scheduled interviews, plant visits, and field trips, or other circumstances may make your class attendance impossible. Each of these situations will be evaluated on an individual basis.
If the instructor cannot be reached in person, by e-mail, or by telephone, the student should leave a message in the instructor's department mailbox. Students can only make up work from an authorized absence and permission from the instructor.
Students will be expected at all times to maintain the university's standards of academic honesty and integrity.
Plagiarism will be considered to have occurred when a student presents as original, in either written or oral form, any idea that the student has acquired from an outside source. Because of the rapidly evolving nature of new media concepts, and the very wide range of cross-referenced possible sources, and to the extent that good ideas are often "in the air," so to speak, it is acknowledged that ideas may form independently in students' minds when clear sources or even nearly identical iterations of those ideas may be available in external sources.
To that extent, and to the extent that innovation in new media is often judged by the slightest variation, and to the extent the instructor does not wish to inhibit the often spontaneous processes by which ideas grow and flower in an individual's mind while the seed of that idea may be forgotten in the rush of development, plagiarism will be judged by degree and intent rather than a strict letter of the law.
If it is determined, however, that plagiarism has occurred, it will be considered grounds for dismissal from class and other sanctions as stated in the Code of Student Rights, Responsibilities and Conduct of IUPUI. Work may be turned in any time prior to the due date. Work will be considered late if not turned in by the end of the class on the date expected.
