users increasingly interact with a heterogeneous collection of computing devices. The applications that users employ on those devices, however, still largely provide user experiences that assume the use of a single computer. This failure is due in part to the difficulty of creating user experiences that span multiple devices, particularly the need to manage identifying, connecting to, and communicating with other devices. In this paper we present an infrastructure based on instant messaging that simplifies adding that additional functionality to applications. Our infrastructure elevates device ownership to a first class property, allowing developers to provide functionality that spans personal devices without writing code to manage users' devices or establish connections among them. It also provides simple mechanisms for applications to send information, events, or commands between a user's devices. We demonstrate the effectiveness of our infrastructure by presenting a set of sample applications built with it and a user study demonstrating that developers new to the infrastructure can implement all of the cross-device functionality for three applications in, on average, less than two and a half hours.

A proactive display is an application that selects content to display based on the set of users who have been detected nearby. For example, the Ticket2Talk [17] proactive display application presented content for users so that other people would know something about them. It is our view that promising patterns for proactive display applications have been discovered, and now we face the need for frameworks to support the range of applications that are possible in this design space. In this paper, we present the Proactive Display (ProD) Framework, which allows for the easy construction of proactive display applications. It allows a range of proactive display applications, including ones already in the literature. ProD also enlarges the design space of proactive display systems by allowing a variety of new applications that incorporate different views of social life and community.

The continuous growth of media databases necessitates development of novel visualization and interaction techniques to support management of these collections. We present Videotater, an experimental tool for a Tablet PC that supports the efficient and intuitive navigation, selection, segmentation, and tagging of video. Our veridical representation immediately signals to the user where appropriate segment boundaries should be placed and allows for rapid review and refinement of manually or automatically generated segments. Finally, we explore a distribution of modalities in the interface by using multiple timeline representations, pressure sensing, and a tag painting/erasing metaphor with the pen. Copyright 2006 acm.

In this paper, we discuss our adaptation of a single-display, single-user commercial application for use in a multidevice, multi-user environment. We wrap Google Earth, a popular geospatial application, in a manner that allows for synchronized coordinated views among multiple instances running on different machines in the same co-located environment. The environment includes a touch-sensitive tabletop display, three vertical wall displays, and a TabletPC. A set of interaction techniques that allow a group to manage and exploit this collection of devices is presented. Copyright 2006 acm.

This paper introduces kinematic templates, an end-user tool for defining content-specific motor space Manipulations in the context of editing 2D visual compositions. As an example, a user can choose the "sandpaper" template to define areas within a drawing where cursor movement should slow down. Our current implementation provides templates that amplify or dampen the cursor's speed, attenuate,litter in a user's movement, guide movement along paths, and add forces to the cursor. Multiple kinematic templates can be defined within a document, with overlapping templates resulting in a form of function composition. A template's strength can also be varied, enabling one to improve one's strokes Without losing the human element. Since kinematic templates guide movements, rather than strictly prescribe them, they constitute a visual composition aid that lies between unaided freehand drawing and rigid drawing aids such as snapping guides, masks, and perfect geometric primitives.

We propose WindowScape, a window manager that uses a photograph metaphor for lightweight, post hoc task management. This is the first task management windowing model to provide intuitive accessibility while allowing windows to exist simultaneously in multiple tasks. WindowScape exploits users' spatial and visual memories by providing a stable thumbnail layout in which to search for windows. A function is provided to let users search the window space while maintaining a largely consistent screen image to minimize distractions. A novel keyboard interaction technique is also presented.

Tactile feedback allows devices to communicate with users when visual and auditory feedback are inappropriate. Unfortunately, current vibrotactile feedback is abstract and not related to the content of the message. This often clashes with the nature of the message, for example, when sending a comforting message. We propose addressing this by extending the repertoire of haptic notifications. By moving an actuator perpendicular to the user's skin, our prototype device can tap the user. Moving the actuator parallel to the user's skin induces rubbing. Unlike traditional vibrotactile feedback, tapping and rubbing convey a distinct emotional message, similar to those induced by human-human touch. To enable these techniques we built a device we call SoundTouch. It translates audio wave files into lateral motion using a voice coil motor found in computer hard drives. SoundTouch can produce motion from below 1Hz to above 10kHz with high precision and fidelity. We present the results of two exploratory studies. We found that participants were able to distinguish a range of taps and rubs. Our findings also indicate that tapping and rubbing are perceived as being similar to touch interactions exchanged by humans.

In this demonstration, we present ArcheoTUI, a new tangible userinterface for the efficient assembly of the 3D scanned fragments of fractured archeological objects. The key idea is to use tangible props for the manipulation of the virtual fragments. In each hand, the user manipulates an electromagnetically tracked prop, and the translations and rotations are directly mapped to the corresponding virtual fragments on the display. For each hand, a corresponding foot pedal is used to clutch the movements of the hands. Hence, the hands of the user can be repositioned, or the user can be switched. The software of ArcheoTUI is designed to easily change assembly hypotheses, beyond classical undo/redo, by using a scene graph. Copyright 2008 acm.

We introduce a new type of interactive surface technology based on a switchable projection screen which can be made diffuse or clear under electronic control. The screen can be continuously switched between these two states so quickly that the change is imperceptible to the human eye. It is then possible to rear-project what is perceived as a stable image onto the display surface, when the screen is in fact transparent for half the time. The clear periods may be used to project a second, different image through the display onto objects held above the surface. At the same time, a camera mounted behind the screen can see out into the environment. We explore some of the possibilities this type of screen technology affords, allowing surface computing interactions to extend 'beyond the display'. We present a single self-contained system that combines these off-screen interactions with more typical multi-touch and tangible surface interactions. We describe the technical challenges in realizing our system, with the aim of allowing others to experiment with these new forms of interactive surfaces.

With advances in pen-based computing devices, handwriting has become an increasingly popular input modality. Researchers have put considerable effort into building intelligent recognition systems that can translate handwriting to text with increasing accuracy. However, handwritten input is inherently ambiguous, and these systems will always make errors. Unfortunately, work on error recovery mechanisms has mainly focused on interface innovations that allow users to manually transform the erroneous recognition result into the intended one. In our work, we propose a mixed-initiative approach to error correction. We describe CueTIP, a novel correction interface that takes advantage of the recognizer to continually evolve its results using the additional information from user corrections. This significantly reduces the number of actions required to reach the intended result. We present a user study showing that CueTIP is more efficient and better preferred for correcting handwriting recognition errors. Grounded in the discussion of CueTIP, we also present design principles that may be applied to mixed-initiative correction interfaces in other domains. Copyright 2006 acm.
