Shape-changing interfaces: a review of the design space and open research questions

Abstract: Shape change is increasingly used in physical user interfaces, both as input and output. Yet, the progress made and the key research questions for shape-changing interfaces are rarely analyzed systematically. We review a sample of existing work on shape-changing interfaces to address these shortcomings. We identify eight types of shape that are transformed in various ways to serve both functional and hedonic design purposes. Interaction with shape-changing interfaces is simple and rarely merges input and output. Three questions are discussed based on the review: (a) which design purposes may shape-changing interfaces be used for, (b) which parts of the design space are not well understood, and (c) why studying user experience with shape-changing interfaces is important.

To feel or not to feel: the role of affect in human-computer interaction

Abstract: The past decade has witnessed an unprecedented growth in user interface and human-computer interaction (HCI) technologies and methods. The synergy of technological and methodological progress on the one hand, and changing user expectations on the other, are contributing to a redefinition of the requirements for effective and desirable human-computer interaction. A key component of these emerging requirements, and of effective HCI in general, is the ability of these emerging systems to address user affect. The objective of this special issue is to provide an introduction to the emerging research area of affective HCI, some of the available methods and techniques, and representative systems and applications.

Printed medium activated interactive communication of multimedia information, including advertising

Abstract: The present invention describes a revolutionary new device bridging the gap between the virtual multimedia-based Internet world and the real world, best exemplified by print media. More particularly, the invention relates to communicating multimedia information using a scanner for machine-readable code containing a link information corresponding to a provider information depicted on the printed medium, a user interface for obtaining user input information corresponding to the provider information, a communications bridge for sending the link information and the user input information via the network, a receiver in communication with the scanner, capable of receiving the link information and user input information, and further capable of receiving and playing a multimedia information sequence, and a portal server in communication with the scanner via the network capable of selecting a multimedia information sequence corresponding to the link information and the user input information.

Comparison of four primary methods for coordinating the interruption of people in human-computer interaction

Abstract: Interruptions can cause people to make mistakes or errors during human-computer interaction (HCI). Interruptions occur as an unavoidable side-effect of some important kinds of human computer-based activities, for example, (a) constantly monitor for unscheduled changes in information environments, (b) supervise background autonomous services, and (c) intermittently collaborate and communicate with other people. Fortunately, people have powerful innate cognitive abilities that they can potentially leverage to manage multiple concurrent activities if they have specific kinds of control and interaction support. There is great opportunity, therefore, for user-interface design to increase people's ability to successfully handle interruptions, and prevent expensive errors. The literature contains very little concrete design wisdom about how to solve the interruption problems in user interfaces (UIs). Coordination support, however, is identified as a most important design topic. This article presents the results of an empirical investigation to compare basic design solutions for coordinating human interruption in computer-based multitasks. A theory-based taxonomy of human interruption is used to identify the four primary methods for coordinating human interruption. An experiment with 36 participants compares these four different design solutions within an abstracted common user multitasking context. The results show important design tradeoffs for coordinating the interruption of people in HCI and support some UI design guidelines. Negotiation support is the best overall solution except where small differences in the timeliness of handling interruptions is critical and then immediate is best.

Nomadic radio: speech and audio interaction for contextual messaging in nomadic environments

Abstract: Mobile workers need seamless access to communication and information services while on the move. However, current solutions overwhelm users with intrusive interfaces and ambiguous notifications. This article discusses the interaction techniques developed for Nomadic Radio, a wearable computing platform for managing voice and text-based messages in a nomadic environment. Nomadic Radio employs an auditory user interface, which synchronizes speech recognition, speech synthesis, nonspeech audio, and spatial presentation of digital audio, for navigating among messages as well as asynchonous notific ation of nely arrived messages. Emphasis is placed on an auditory modality as Nomadic Radio is designed to be used while performing other tasks in a user's everyday environment; a range of auditory cues provides peripheral awareness of incoming messages. Notification is adaptive and cntext sensitive; messages are presented as more or less obtrsive based on importance inferred from content filtering, whether the user is engaged in conversation and his or her own recent responses to prior messages. Auditory notifications are dynamically scaled from ambient sound through recorded voice cues up to message summaries. Iterative design and a preliminary user evaluation suggest that audio is an appropriate medium for mobile messaging, but that care must be taken to minimally intrude on the wearer's social and physical environment.
