McCrickard, D. Scott and Lewis, Clayton (2012): Designing for cognitive limitations. In: Proceedings of DIS12 Designing Interactive Systems 2012. pp. 805-806. Available online
People with cognitive disabilities that affect their memory, attention, and comprehension can become overwhelmed when using technology -- just as cognitively-demanding situations like driving or multitasking can hinder technology use for most people. However, appropriately-designed technology can assist in overcoming cognitive disabilities and cognitive limitations. This workshop seeks to bring together researchers and practitioners with design experience in the many areas of cognitive disability and cognitive limitation to exchange, evolve, and develop strategies for design. Workshop participants will present key lessons from their own experiences, and workshop activities will employ claims-based design strategies toward identifying, comparing, and mapping approaches for addressing cognitive disabilities and limitations.

Storyboards offer designers a way to illustrate a narrative. Their creation can be enabled by tools supporting sketching or widget collections. As designers often incorporate previous ideas, we contribute the notion of blending the reappropriation of artifacts and their design tradeoffs with storyboarding. We present PIC-UP, a storyboarding tool supporting reappropriation, and report on two studies -- a long-term investigation with novices and interviews with experts. We discuss how it may support design thinking, tailor to different expertise levels, facilitate reappropriation during storyboarding, and assist with communication.

Artifacts can be used to inspire, guide, and create new designs. As approaches to design can range from focusing on inspiration to formalized reasoning, we seek to create and study artifacts that combine the use of images and rationale. In this paper, we contribute an understanding of the relationship between imagery and rationale through an investigation of an artifact made of both. Through a study of group design sessions, we find images can provide access to rationale, moments of inspiration can be balanced with rationale, and differences between images and rationale must be reconciled. We conclude with thoughts on how such artifacts might be leveraged by the design community.

Artifacts-representations that express properties or captured information-can serve to inspire, represent, and manage the decisions made throughout the design process. This workshop will explore how these artifacts are created, used, and reused during design projects, toward understanding the overall impact on the larger discipline of design. Through active engagement with novel design artifacts and methods, workshop participants will examine, categorize, and evaluate various design artifacts.

Many software systems fail to address their intended purpose because of a lack of user involvement and requirements deficiencies. This paper discusses the elaboration of a requirements-analysis process that integrates a critical-parameter-based approach to task modeling within a user-centric design framework. On one hand, adapting task models to capture requirements bridges the gap between scenarios and critical parameters which benefits design from the standpoint of user involvement and accurate requirements. On the other hand, using task models as a reusable component leverages requirements reuse which benefits design by increasing quality while simultaneously reducing development costs and time-to-market. First, we present the establishment of both a user-centric and reuse-centric requirements process along with its implementation within an integrated design tool suite. Secondly, we report the design, procedures, and findings of two user studies aimed at assessing the feasibility for novice designers to conduct the process as well as evaluating the resulting benefits upon requirements-analysis deliverables, requirements quality, and requirements reuse.

In: Proceedings of the 2009 International Conference on Advances in Computer-Human Interactions 2009. pp. 32-37. Available online
Device-assisted navigation is rapidly becoming a major topic in computer science. PDAs and other small devices are enabling the introduction of navigational assistants to many different spaces. These areas are generally filled with points of interest with which users may choose to interact with. The natural behavior of users in such a space is to explore, interacting with objects the user deems worthy of further interaction. We call this behavior 'opportunistic navigation.' In this paper we define the challenges associated with and put forward several criteria for enabling opportunistic navigation in Location-Based Notification Systems. Our criteria have been implemented in the form of a prototype navigational assistant, SeeVT-ART, and have undergone a preliminary field test.

Designing CSCW systems that support the widely varying needs of targeted users is difficult. There is no silver bullet technology that enables users to effectively collaborate with one another in different contexts. We propose a method of collaborative systems evaluation that enables novice evaluators to make insightful observations about the systems they evaluate at a level comparable to experts in certain situations. These observations come in the form of a categorical breakdown analysis of a laboratory study. The quantity and type of breakdowns can then be connected to recommended CSCW tools and features developed and described in the related literature. We conducted a study to explore the results generated when the method was applied by both experts and novices in the field of CSCW. We observed that experts found the method to be usable, and that novices capitalized on the knowledge embodied in the breakdown categories to make categorizations similar to those of experts.

This work seeks to strengthen interaction within a research community through a centrally-located physical device that presents online presence information in a semi-public space. The device uses a map metaphor to represent a set of connected labs. As people move within the lab, those who wish to interact with lab users can use the display to guide their interaction approaches, by supporting educated guesses as to arrivals, departures, and work patterns. The paper reports on the lessons learned about the device's characteristics, and provides anecdotes and observations on ways in which this type of device can improve communication and enhance community.

Somervell, Jacob and McCrickard, D. Scott (2005): Better discount evaluation: illustrating how critical parameters support heuristic creation. In Interacting with Computers, 17 (5) pp. 592-612. Available online
This paper describes a heuristic creation process based on the notion of critical parameters, and a comparison experiment that demonstrates the utility of heuristics created for a specific system class. We focus on two examples of using the newly created heuristics to illustrate the utility of the usability evaluation method, as well as to provide support for the creation process, and we report on successes and frustrations of two classes of users, novice evaluators and domain experts, who identified usability problems with the new heuristics. We argue that establishing critical parameters for other domains will support efforts in creating tailored evaluation tools.

In: Proceedings of DIS04: Designing Interactive Systems: Processes, Practices, Methods, & Techniques 2004. pp. 279-288. Available online
We elaborate a proposal for capturing, extending, and reusing design knowledge gleaned through usability testing. The proposal is specifically targeted to address interface design for notification systems, but its themes can be generalized to any constrained and well-defined genre of interactive system design. We reiterate arguments for and against using critical parameters to characterize user goals and usability artifacts. Responding to residual arguments, we suggest that clear advantages for research cohesion, design knowledge reuse, and HCI education are possible if several challenges are overcome. As a first step, we recommend a slight variation to the concept of a critical parameter, which would allow both abstract and concrete knowledge representation. With this concept, we demonstrate a feasible approach by introducing equations that elaborate and allow evolution of notification system critical parameters, which is made operational with a variety of usability evaluation instruments. A case study illustrates how one general instrument allowed system designs to be meaningfully compared and resulted in valuable inferences for interface reengineering. Broad implications and conclusions about this approach will be of interest to others concerned with using critical parameters in interface design, development of notification systems interfaces, or approaches to design rationale and knowledge reuse.

In: Proceedings of the 16th annural ACM Symposium on User Interface Software and Technology November, 2-5, 2003, Vancouver, Canada. pp. 21-30. Available online
Classroom BRIDGE supports activity awareness by facilitating planning and
goal revision in collaborative, project-based middle school science. It
integrates large-screen and desktop views of project times to support
incidental creation of awareness information through routine document
transactions, integrated presentation of awareness information as part of
workspace views, and public access to subgroup activity. It demonstrates and
develops an object replication approach to integrating synchronous and
asynchronous distributed work for a platform incorporating both desktop and
large-screen devices. This paper describes an implementation of these concepts
with preliminary evaluation data, using timeline-based user interfaces.

McCrickard, D. Scott, Czerwinski, Mary and Bartram, Lyn (2003): Introduction: design and evaluation of notification user interfaces. In International Journal of Human-Computer Studies, 58 (5) pp. 509-514.
Notification systems attempt to deliver current, important information to
the computer screen in an efficient and effective manner. All notification
systems require that the user attends to them to at least some degree if they
are to succeed. Examples of notification systems include instant messaging
systems, system and user status updates, email alerts and news and stock
tickers. The benefits of notification systems are numerous, including rapid
availability of important information, access to nearly instantaneous
communication and heightened awareness of the availability of personal
contacts. While the popularity of these systems has skyrocketed in recent
years, the effects of incoming notifications on ongoing computing tasks have
been relatively unexplored. The investigation of the costs, benefits and the
optimal display of instant messages and all notifications in the context of
desktop or mobile computing tasks falls in the general arena of psychological
research on alerting and disruptions, but also requires research contributions
from design, computer science and information visualization. To date, much of
the psychological research on interruption leverages theoretical task
constructions. In this special issue, we focus on the nature of interruptions
such as messaging while computing and how to optimize the user experience.

Designing and evaluating notification systems represents an emerging
challenge in the study of human-computer interaction. Users rely on
notification systems to present potentially interruptive information in an
efficient and effective manner to enable appropriate reaction and
comprehension. Little is known about the effects of these systems on ongoing
computer tasks. As the research community strives to understand information
design suitable for opposing usage goals, few existing efforts lend themselves
However, three often conflicting design objectives are interruption to
primary tasks, reaction to specific notifications, and comprehension of
information over time. Based on these competing parameters, we propose a
unifying research theme for the field that defines success in notification
systems design as achieving the desirable balance between attention and
utility. This paradigm distinguishes notification systems research from
traditional HCI by centering on the limitations of the human attention system.
In a series of experiments that demonstrate this research approach and
investigate use of animated text in secondary displays, we describe two
empirical investigations focused on the three critical parameters during a
browsing task. The first experiment compares tickering, blasting, and fading
text, finding that tickering text is best for supporting deeper comprehension,
fading best facilitates reaction, and, compared to the control condition, none
of the animated displays are interruptive to the browsing task. The second
experiment investigates fading and tickering animation in greater detail with
similar tasks -- at two different speeds and sizes. Here, we found smaller
displays allowed better reaction but were more interruptive, while slower
displays provides increased comprehension. Overall, the slow fade appears to be
the best secondary display animation type tested. Focusing research and user
studies within this field on critical parameters such as interruption,
reaction, and comprehension will increase cohesion among design and evaluation
efforts for notification systems.

People working collaboratively must establish and maintain awareness of one
another's intentions, actions and results. Notification systems typically
support awareness of the presence, tasks and actions of collaborators, but they
do not adequately support awareness of persistent and complex activities. We
analysed awareness breakdowns in use of our Virtual School system -- stemming
from problems related to the collaborative situation, group, task and tool
support -- to motivate the concept of activity awareness. Activity awareness
builds on prior conceptions of social and action awareness, but emphasizes the
importance of activity context factors like planning and coordination. This
work suggests design strategies for notification systems to better support

Addressing the need to tailor usability evaluation methods (UEMs) and promote effective reuse of HCI knowledge for computing activities undertaken in divided-attention situations, we present the foundations of a unifying model that can guide evaluation efforts for notification systems. Often implemented as ubiquitous systems or within a small portion of the traditional desktop, notification systems typically deliver information of interest in a parallel, multitasking approach, extraneous or supplemental to a user's attention priority. Such systems represent a difficult challenge to evaluate meaningfully. We introduce a design model of user goals based on blends of three critical parameters -- interruption, reaction, and comprehension. Categorization possibilities form a logical, descriptive design space for notification systems, rooted in human information processing theory. This model allows conceptualization of distinct action models for at least eight classes of notification systems, which we describe and analyze with a human information processing model. System classification regions immediately suggest useful empirical and analytical evaluation metrics from related literature. We present a case study that demonstrates how these techniques can assist an evaluator in adapting traditional UEMs for notification and other multitasking systems. We explain why using the design model categorization scheme enabled us to generate evaluation results that are more relevant for the system redesign than the results of the original exploration done by the system's designers.
