Das, Anita, Faxvaag, Arild and Svanaes, Dag (2011): Interaction design for cancer patients: do we need to take into account the effects of illness and medication?. In: Proceedings of the 2011 annual conference on Human factors in computing systems 2011. pp. 21-24.
In this paper we explore how having cancer and receiving therapy influences upon patients' ability to use an online healthcare system. The motivation is that no empirically based design guidelines are available concerning this user group. Ignoring possible effects of illness and therapy can result in systems with poor usability and user acceptance. A case-control usability test with 14 cancer patients and 14 matched controls revealed that the cancer patients experienced significantly more difficulties compared with the healthy controls using a web-based online healthcare system. We conclude that designers of online healthcare systems need to take into consideration the unique challenges of being ill and/or using medication.

Controlled laboratory-based usability assessments of mobile information and communications technologies (ICT) for hospitals have been conducted. As part of these assessments, clinicians have acted out mobile work scenarios and used the systems to solve related tasks. The evaluations show that relevant usability issues go beyond those of graphical user interfaces. Many of these usability issues only show up when the real-world context of use is replicated in the laboratory to a high degree of fidelity. The complexity of the context of use for mobile ICT in hospitals has motivated us to explore training simulation fidelity theories. Based on a review of the training simulation literature, a set of fidelity dimensions through which training simulations are often adjusted to meet specific goals are identified. It is argued that the same mechanisms can be used in usability assessments of mobile ICT for hospitals. Our argument is substantiated by using the identified set of fidelity dimensions in a retrospective analysis of two usability assessments. The analysis explains how the configuration of fidelity dimensions, each reflecting various degrees of realism vis-à-vis the actual performance context, contributed to the identification of relevant usability issues.

It is widely recognized that system usability requires active involvement of end-users in all phases of software development, and there is currently a broad consensus among researchers and practitioners in the field as to what constitutes a good user-centered design process. Despite this, many systems development projects still fail when it comes to addressing usability issues and appropriately involving users in the design process. We find that a project's boundary conditions are becoming increasingly important for the potential impact of user-centered design activities, and hence the success of the end result of the project. We propose and define "context of design" as a concept to embrace the socio-technical system in which user-centered design takes place. The context of design includes, but is not limited to, the internal structure of the developer and the client organizations, contractual and tender issues, software engineering tools, and stakeholder agendas and relations. We illustrate the reasoning with various cases in which user-centered design has been constrained by factors in the context of design. We recommend that user-centered-design projects give priority to an early identification of factors in the context of design that pose risks to end-product usability. By analyzing the context of design for each project, we may be able to better tailor user-centered design activities to reach the goal of building a more usable end-result.

The purpose of the reported study has been to validate empirically the usefulness of using the WAI accessibility guidelines WCAG 1.0 as a heuristic for website accessibility. Through controlled usability tests of two websites with disabled users (N=7) and a control group (N=6) we found that only 27% of the identified website accessibility problems could have been identified through the use of WCAG. We conclude from this that in its current version, the application of WCAG alone is not sufficient to guarantee website accessibility. WCAG has a large potential for improvement, and our data point to some problem areas that we suggest should be included. We recommend that future versions of accessibility guidelines should be based on empirical data and validated empirically.

In the present study we compare interaction techniques for using handheld devices together with stationary displays in a hospital setting. A set of prototype implementations were developed and tested for a pre-surgery scenario with pairs of physicians and patients. The participants were asked to rank the interaction techniques in order of preference. The results show highest ranking for a distributed user interface where the GUI elements reside on the handheld and where the stationary display is used for showing media content. An analysis of the factors affecting the usability shows that in addition to GUI usability, the interaction techniques were ranked based on ergonomic and social factors specific to the use situation. The latter include the physicality of the patient bed and how computing devices potentially interrupt the face-to-face communication between physician and patient. The study illustrates how the usability of interaction techniques for ubiquitous computing is affected by the ergonomic and social factors of each specific use context.

Svanaes, Dag and Seland, Gry (2004): Putting the users center stage: role playing and low-fi prototyping enable end users to design mobile systems. In: Dykstra-Erickson, Elizabeth and Tscheligi, Manfred (eds.) Proceedings of ACM CHI 2004 Conference on Human Factors in Computing Systems April 24-29, 2004, Vienna, Austria. pp. 479-486.
This paper sums up lessons learned from a sequence of cooperative design workshops where end users were enabled to design mobile systems through scenario building, role playing, and low-fidelity prototyping. We present a resulting fixed workshop structure with well-chosen constraints that allows for end users to explore and design new technology and work practices. In these workshops, the systems developers get input to design from observing how users stage and act out current and future use scenarios and improvise new technology to fit their needs. A theoretical framework is presented to explain the creative processes involved and the workshop as a user-centered design method. Our findings encourage us to recommend the presented workshop structure for design projects involving mobility and computer-mediated communication, in particular project where the future use of the resulting products and services also needs to be designed.

Svanaes, Dag (2001): Context-Aware Technology: A Phenomenological Perspective. In Human-Computer Interaction, 16 (2) pp. 379-400.
Context-aware systems are currently to a large extent designed from a systems perspective. Research on these technologies has so far mostly been focused on exploring what can be built and less on how it will show up in people's lives. The existing theory and practice in human-computer interaction has mainly evolved from work on graphical user interfaces, and additional theory is required to enable user-centered design of context-aware systems. Interaction with such systems is to a larger extent physical, and an appropriate theory consequently needs to account for the user's bodily nature. We have found the phenomenology of Merleau-Ponty to be a good starting point for the development of such theory. With its first-person focus on the lived body and its relation to the environment, it provides a conceptual framework well suited for understanding context-aware systems from the user's perspective. The perspective moves the focus from seeing a context-aware system as an artifact "sensing" information, to seeing it as an interactive system with a physical user interface. This makes the distinction between foreground and background interaction a property not of the system, but of the situation. A consequence of this philosophical standpoint is that context can never be a property of the world, but that context rather is the horizon within which the user makes sense of the world. The phenomenological perspective enables a systematic exploration of the design space for context-aware systems-as they appear to the user. It further enables an analysis of the requirements for a seamless integration between screen-based and context-aware systems. The essay ends by pointing to the need for making the technology available in a form that can be easily utilized by interaction designers.

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.
