Ferré, Xavier, Bevan, Nigel and Escobar, Tomás Antón (2010): UCD method selection with usability planner. In: Proceedings of the Sixth Nordic Conference on Human-Computer Interaction 2010. pp. 829-830.
The diversity of User Centred Design (UCD) methods and the difficulties for estimating their cost-effectiveness make planning usability activities in systems development a hard task. Usability Planner is a tool to support the selection of UCD methods to be applied in a particular project or organization, and to estimate the relative cost benefits of applying usability methods at different stages.

Over the last 15 years, a comprehensive range of international standards has
been developed to define the general principles of user-centred design and good
practice in user interface design. Most of the standards specify general
principles rather than the precise details of the interface. The paper briefly
describes how standards are created and reviews the definitions of usability.
HCI and usability standards are described in the categories: usability
definitions, use in context, software interface and interaction, hardware
interface, documentation, the development process and capability of the
organization. The applicability of the standards is discussed.

Earthy, Jonathan, Jones, Brian Sherwood and Bevan, Nigel (2001): The improvement of human-centred processes -- facing the challenge and reaping the benefit of ISO 13407. In International Journal of Human-Computer Studies, 55 (4) pp. 553-585.
Human-centred design processes for interactive systems are defined in ISO
13407 and the associated ISO TR 18529. The publication of these standards
represents a maturing of the discipline of user-centred design. The systems
development community see that (at last) Human Factors has processes which can
be managed and integrated with existing project processes. This internationally
agreed set of human-centred design processes provides a definition of the
capability that an organization must possess in order to implement user-centred
design effectively. It can also be used to assess the extent to which a
particular development project employs user-centred design. As such, it
presents a challenge to the Human Factors community, and indeed a definition of
good practice may even be regarded by some as an unwelcome constraint. This
paper presents the background to the process-level definition of user-centred
design and describes how it relates to current practice. The challenges,
benefits and use of a defined human-centred design process are presented. The
implications for Human Factors and other disciplines are discussed. In
Appendices A-D, the process terminology and the contents of ISO 13407 and ISO
TR 18529 are described in more detail, and three examples are given (in
Appendix D) of using this process improvement approach to improve the actual
design methods in three organizations.

This paper reports a method for measuring usability in terms of task performance -- achievement of frequent and critical task goals by particular users in a context simulating the work environment. The terms usability and quality in use are defined in international standards as the effectiveness, efficiency and satisfaction with which goals are achieved in a specific context of use. The performance measurement method gives measures which, in combination with measures of satisfaction, operationalize these definitions. User performance is specified and assessed by measures including task effectiveness (the quantity and quality of task performance) and User efficiency (effectiveness divided by task time). Measures are obtained with users performing tasks in a context of evaluation which matches the intended context of use. This can also reveal usability problems which may not become evident if the evaluator interacts with the user. The method is supported by tools which make it practical in commercial timescales. The method has been widely applied in industry, and can be adapted for use early in design, and to evaluate non-computer products and the performance of small work groups.

In a paper at HCI International 1991, Bevan et al (1991) asked "What is usability?", and distinguished between broad and narrow approaches to usability. This paper builds on that distinction, identifying the broad approach to usability with the higher level quality objective of "quality of use" (Bevan, 1995a). Quality of use should be the major design objective for an interactive product: does the product enable the intended users to achieve the intended tasks? This relates usability to business objectives and elevates usability from an optional extra to the prime design goal. The narrow approach is complementary and is concerned with the design of features of the product which are a pre-requisite for quality of use. The two different interpretations of usability lead to two approaches to the specification and evaluation of usability.

Bevan, Nigel and Macleod, Miles (1994): Usability Measurement in Context. In Behaviour and Information Technology, 13 (1) pp. 132-145.
Different approaches to the measurement of usability are reviewed and related to definitions of usability in international standards. It is concluded that reliable measures of overall usability can only be obtained by assessing the effectiveness, efficiency and satisfaction with which representative users carry out representative tasks in representative environments. This requires a detailed understanding of the context of use of a product. The ESPRIT MUSiC project has developed tools which can be used to measure usability in the laboratory and the field. An overview is given of the methods and tools for measuring user performance, cognitive workload, and user perceived quality.

Analysis of interaction between users and a system, based on video-assisted observation, can provide a highly informative and effective means of evaluating usability. To obtain valid and reliable results, the people observed should be representative users performing representative work tasks in appropriate circumstances, and the analysis should be methodical. The MUSiC Performance Measurement Method (PMM) -- developed at NPL as part of the ESPRIT Project MUSiC: Metrics for Usability Standards in Computing -- provides a validated method for making and analysing such video recordings to derive performance-based usability metrics. PMM is supported by the DRUM software tool which greatly speeds up analysis of video, and helps manage evaluations.

This panel will consider the role of usability measurement in the design process. It will address the time needed to perform usability evaluations and compare this process with that of expert assessment. This topic will be discussed in the industrial context of developing computer products within strict timescales. However it will also be seen against the traditional problem of needing to set usability goals and to measure their achievement if usability is to be given the same priority as the more technical software engineering objectives.

The European Directive on the "minimum health and safety requirements for work with display screen equipment" contains minimum ergonomic requirements for the equipment, environment and operator/computer interface. National legislation which implements the Directive is required by the end of 1992, and may make reference to relevant standards. ISO 9241 is being developed as a multi-part standard which has a similar scope to the Directive, and provides a potential means for interpreting some of the more general requirements of the Directive which include: "software must be easy to use" and "the principles of software ergonomics must be applied".

INTERACT 90 - 3rd IFIP International Conference on Human-Computer Interaction August 27-31, 1990, Cambridge, UK. pp. 357-361.
This paper describes work in progress in Working Group 5 of the International Organisation for Standardisation Technical committee 159 subcommittee 4 (ISO TC159/SC4/WG5). While many standards are concentrating on what guidelines can be given regarding the design of user interfaces and dialogues, subgroup 2 of TC159/SC4/WG5 is taking a holistic approach to the issue of the usability of products. A standard is being developed which will specify how producers and consumers of products may communicate with each other about the usability of products.

INTERACT 90 - 3rd IFIP International Conference on Human-Computer Interaction August 27-31, 1990, Cambridge, UK. pp. 435-440.
This paper reports a case study of the evaluation of the effectiveness of a draft standard containing human factors guidelines for menu interface design. Three designers were given a week to study the guidelines, before spending a day using the guidelines to redesign a menu interface. They were asked to justify their design in terms of the guidelines. The designers made errors or had difficulties with 91% of the guidelines. The cause of the errors and difficulties was analysed, which enabled recommendations for improvements to be made. Despite the difficulties with interpretation of the guidelines, the resulting interfaces only violated an average of 11% of the guidelines which could be assessed. It is concluded that it was difficult for the designers to integrate detailed design guidelines with their existing experience.

Human conversations are complex interactions motivated by both task-related and social goals. It is proposed that the optimal form of conversational interaction with a computer is a computer conversation which closely emulates the nature of a human conversation in similar circumstances. The cultural differences between computer conversations and human conversations are identified, and it is suggested how the crucial social factors in human conversation could be integrated into a conversational model of computer interaction, structured by the need to achieve mutual goals.

MAVIS uses a microprocessor to extend as widely as possible the activities that a handicapped person can carry out. Users can read, write, modify and store information, and interact creatively with their environment. It is designed for use at home, in education and as a tool to enable a handicapped person to carry out a job. A Mark II version has been constructed which is housed in a briefcase and connects to a standard television receiver. Other attachments can be added as required by the handicap of the owner and the purpose of use.

The National Physical Laboratory has developed a microprocessor system for interviewing patients to obtain their medical histories. The doctor specifies the interview in the form of a numbered flowchart. When presented to the patient this emulates a friendly doctor asking questions requiring simple YES or NO answers. The system is easy to use, and collects accurate information.

Bevan, Nigel (1981): Is There an Optimum Speed for Presenting Text on a VDU?. In International Journal of Man-Machine Studies, 14 (1) pp. 59-76.
When a computer generates text for a Visual Display Unit, it is usually presented at the fastest speed available. The experiments described in this paper investigate the effect of different presentation speeds on performance in a learning task. It was found that performance deteriorated at speeds similar to, or faster than reading speed. If understanding and retention of textual material is important, the optimum presentation speed is in the range 10-15 characters per second.

Knowledge wants to be free !
We have decided to give away world-class educational materials
because we believe that universal access to high quality education is key to the building
of peace, sustainable social and economic development, and intercultural dialogue.
To calculate just have much we have saved you, our wonderful readers, we compare our free encyclopedia to two
books we love:
$110: Human-Computer Interaction by Dix et al (a great textbook but without video interviews)
$116: Shneiderman's Designing the User Interface
(a great textbook but without video interviews).
As you are reading our encyclopedia on your iPad/tablet (and saving a few trees), we estimate that the price would be $90 if sold as an eBook.
With that number, we can calculate how much money we have saved our readers, based on calculating the number of readers.
How we calculate readership
Because of our online and tablet/iPad approach to publishing, we are able to precisely measure reading behaviour across hundreds of parameters in realtime: Anything from reading
speed, drop-off points in the text, reader demographics, and much more.
Based on our server logs and the Google Analytics API,
we calculate the number of readers as described in the calculation method below.
A reader is not the same as a simple pageview and a reader is not the same as a
website visitor (as described in our calculation method below).
We calculate readership for two types of readers:
- Readers that have read our whole encyclopedia, much the same way you read a printed book
- Readers that have reader an individual chapter
Calcalution method: How we define a reader
- First we use the Google Analytics API to get a report of the number of unique human visitors to a chapter/page. Google runs its business on ads and thus completely relies on the ability to distinguish between a human visitor and an automated request. If not, you could earn millions on automating clicks on Google Ads.
- We then compare that number to our Apache webserver logs, which report the much higher number of actual visits to a chapter/page (both human and automated). We calculate the difference in percent, which we call an "exaggeration factor", which we use in step 6 below.
- With a large part of the visitors excluded, we further exclude any visitor who:
- has not remained on the page for at least 3 minutes (this factor is calculated by recording visit durations of 1000 randomly selected visitors) or has not printed the page (i.e. has not visited the printerfriendly version of the chapter/page)
- has not scrolled the page (this factor is calculated by recording scroll movements on 1000 randomly selected visitors)
- We then further exclude "double readers", i.e. readers who read a portion of a chapter and then returns in,
say, a week or a month to read the rest.
Although this person's reading activity spans multiple server sessions, the person is only counted as a single reader.
We categorize a "double reader" as a visitor who:
- visits a page, or multiple pages, across multiple server sessions
- qualifies to be defined as a reader, cf step 1-3 above, in all server sessions
- uses the same originating IP address
- We then subtract 5% from the final number to counter-balance a last remaining factor, namely the situation where one reader reads a chapter on his/her tablet
using a WiFi connection (and counted as one reader) but then picks up his other tablet using a 3G dongle
(with another IP address) and re-reads some of the chapter. That will equal two readers, not one. We have no way
of calculating how many times this situation arises, but to be on the safe side we subtract 5%
from the final number.
- We then take half of the "exaggeration factor" from step 2 and substract from the final number. We do this for no rational reason. We do it only as a further measure to be certain that our number of readers is not inflated.
- To qualify as a reader who has read our whole encyclopedia - much the same way you read a printed book - that person must have qualified as a reader (cf. 1-6 above) of at least 80% of the encyclopedia chapters.
As a result, we have eliminated everything from automated requests to the more casual visitors. That leaves us with what we can safely call readers.
