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. For example, visual and auditory information can be presented simultaneously rather than presenting all visual or all auditory information. Memory principles[ edit ] Replace memory with visual information: knowledge in the world. A user should not need to retain important information solely in working memory or retrieve it from long-term memory.
A menu, checklist, or another display can aid the user by easing the use of their memory.
However, the use of memory may sometimes benefit the user by eliminating the need to reference some type of knowledge in the world e. The use of knowledge in a user's head and knowledge in the world must be balanced for an effective design.
Principle of predictive aiding. Proactive actions are usually more effective than reactive actions. A display should attempt to eliminate resource-demanding cognitive tasks and replace them with simpler perceptual tasks to reduce the use of the user's mental resources.
This will allow the user to focus on current conditions, and to consider possible future conditions.
Originally at ethologist, he has worked in the IT and finance industry, the civil service and City and Manchester Universities. His research spans software engineering, human computer interaction, cognitive and social science, with recent interests in scenario based design, methods for requirements engineering, analysis and modelling complex socio technical systems, visualisation and creative design.
His recent books include: Multimedia and virtual reality: Designing multisensory user interfaces. He serves on the editorial boards of several journals in the software engineering and human computer interaction. John pioneered the use of ethnography in systems design and Andy has been working on shaping computing around the social for the best part of 20 years now.
He has published widely, including a couple of textbooks on ethnography for design. He was awarded an RCUK Academic Fellowship in , which solidified his work at Nottingham in the Mixed Reality Laboratory, an interdisciplinary research group with an international reputation for innovative work at the interface between computing and society. She started her career in industry, as a software engineer, but soon moved into academia, where she developed a focus on the use and usability of computer systems.
Ann leads research projects on human error and on interacting with information, with a focus on modelling situated interactions. She has been technical programme chair for several conferences, the most recent being NordiCHI Ben Challis Ben Challis is a composer, performer and technologist.
With research interests that embrace the notion of design-for-all within music-performance, he has worked on various projects that explore alternative modes of interaction with sound and music for people with specific individual needs.
As a performer, he works with these same technologies, exploring their creative and expressive potential within free-improvisation.
As composer he has composed scores for film and theatre productions. After doing a mathematics degree, and a Master's thesis on split-brain neuropsychology, Brian joined the New Zealand Army, where he was the first specialist to complete regular army officer cadet training. He worked as an army psychologist, and then in computer operational simulations wargames , while simultaneously raising four wonderful children, until he retired in as a Major.
Brian then completed his doctorate on online groups, and students at his university used the social voting system he built until the World Wide Web arrived. More recently, he was the senior editor of the Handbook of Research on Socio-Technical Design and Social Networking Systems, written by over a hundred leading experts worldwide.
His interests include computing, psychology, quantum theory and motor-cycle riding.
Caroline Hummels Prof. Her current activities concentrate on designing for personal, social and societal transformation, with a special focus on health and well-being. She designs for transformation based on the aesthetics of interaction with open, disruptive innovative systems within a societal context.
Moreover, she is a designer-researcher with extensive experience in interaction design, education and research-trough design. She has developed various research prototypes and installations next to design methods, techniques and processes. Moreover, she has been a member of a variety of international program committees and national Think Tanks since , and has given a large number of keynote speeches, invited lectures and workshops at conferences, international universities and for industry world wide.
His research interests are where human-computer interaction and software engineering intersect. Most of his current projects aim to help software users to create code for themselves, and to effectively share that code with one another.
