Song, Hyunyoung, Grossman, Tovi, Fitzmaurice, George W., Guimbretiere, Francois, Khan, Azam, Attar, Ramtin and Kurtenbach, Gordon (2009): PenLight: combining a mobile projector and a digital pen for dynamic visual overlay. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 143-152. Available online
“Digital pen systems, originally designed to digitize annotations made on physical paper, are evolving to permit a wider variety of applications. Although the type and quality of pen feedback (e.g., haptic, audio, and visual) have a huge impact on advancing the digital pen technology, dynamic visual feedback has yet to be fully investigated. In parallel, miniature projectors are an emerging technology with the potential to enhance visual feedback for small mobile computing devices. In this paper we present the PenLight system, which is a testbed to explore the interaction design space and its accompanying interaction techniques in a digital pen embedded with a spatially-aware miniature projector. Using our prototype, that simulates a miniature projection (via a standard video projector), we visually augment paper documents, giving the user immediate access to additional information and computational tools. We also show how virtual ink can be managed in single and multi-user environments to aid collaboration and data management. User evaluation with professional architects indicated promise of our proposed techniques and their potential utility in the paper-intensive domain of architecture.”

Fitzmaurice, George W., Matejka, Justin, Khan, Azam, Glueck, Mike and Kurtenbach, Gordon (2008): PieCursor: merging pointing and command selection for rapid in-place tool switching. In: Proceedings of ACM CHI 2008 Conference on Human Factors in Computing Systems April 5-10, 2008. pp. 1361-1370. Available online
“We describe a new type of graphical user interface widget called the "PieCursor." The PieCursor is based on the Tracking Menu technique and consists of a radial cluster of command wedges, is roughly the size of a cursor, and replaces the traditional cursor. The PieCursor technique merges the normal cursor function of pointing with command selection into a single action. A controlled experiment was conducted to compare the performance of rapid command and target selection using the PieCursor against larger versions of Tracking Menus and a status quo Toolbar configuration. Results indicate that for small clusters of tools (4 and 8 command wedges) the PieCursor can outperform the toolbar by 20.8% for coarse pointing. For fine pointing, the performance of the PieCursor degrades approximately to the performance found for the Toolbar condition.”

Khan, Azam, Matejka, Justin, Fitzmaurice, George W. and Kurtenbach, Gordon (2005): Spotlight: directing users' attention on large displays. In: Proceedings of ACM CHI 2005 Conference on Human Factors in Computing Systems 2005. pp. 791-798. Available online
“We describe a new interaction technique, called a spotlight, for directing the visual attention of an audience when viewing data or presentations on large wall-sized displays. A spotlight is simply a region of the display where the contents are displayed normally while the remainder of the display is somewhat darkened. In this paper we define the behavior of spotlights, show unique affordances of the technique, and discuss design characteristics. We also report on experiments that show the benefit of using the spotlight a large display and standard desktop configuration. Our results suggest that the spotlight is preferred over the standard cursor and outperforms it by a factor of 3.4 on a wall-sized display.”

Khan, Azam, Fitzmaurice, George W., Almeida, Don, Burtnyk, Nicolas and Kurtenbach, Gordon (2004): A remote control interface for large displays. In: Proceedings of the 2004 ACM Symposium on User Interface Software and Technology 2004. pp. 127-136. Available online
“We describe a new widget and interaction technique, known as a \"Frisbee,\" for interacting with areas of a large display that are difficult or impossible to access directly. A frisbee is simply a portal to another part of the display. It consists of a local \"telescope\" and a remote \"target\". The remote data surrounded by the target is drawn in the telescope and interactions performed within it are applied on the remote data. In this paper we define the behavior of frisbees, show unique affordances of the widget, and discuss design characteristics. We have implemented a test application and report on an experiment that shows the benefit of using the frisbee on a large display. Our results suggest that the frisbee is preferred over walking back and forth to the local and remote spaces at a distance of 4.5 feet.”

“We describe a new type of graphical user interface widget, known as a
"tracking menu." A tracking menu consists of a cluster of graphical buttons,
and as with traditional menus, the cursor can be moved within the menu to
select and interact with items. However, unlike traditional menus, when the
cursor hits the edge of the menu, the menu moves to continue tracking the
cursor. Thus, the menu always stays under the cursor and close at hand. In this
paper we define the behavior of tracking menus, show unique affordances of the
widget, present a variety of examples, and discuss design characteristics. We
examine one tracking menu design in detail, reporting on usability studies and
our experience integrating the technique into a commercial application for the
Tablet PC. While user interface issues on the Tablet PC, such as preventing
round trips to tool palettes with the pen, inspired tracking menus, the design
also works well with a standard mouse and keyboard configuration.”

“This paper describes StyleCam, an approach for authoring 3D viewing
experiences that incorporate stylistic elements that are not available in
typical 3D viewers. A key aspect of StyleCam is that it allows the author to
significantly tailor what the user sees and when they see it. The resulting
viewing experience can approach the visual richness and pacing of highly
authored visual content such as television commercials or feature films. At the
same time, StyleCam allows for a satisfying level of interactivity while
avoiding the problems inherent in using unconstrained camera models. The main
components of StyleCam are camera surfaces which spatially constrain the
viewing camera; animation clips that allow for visually appealing transitions
between different camera surfaces; and a simple, unified, interaction technique
that permits the user to seamlessly and continuously move between
spatial-control of the camera and temporal-control of the animated transitions.
Further, the user's focus of attention is always kept on the content, and not
on extraneous interface widgets. In addition to describing the conceptual model
of StyleCam, its current implementation, and an example authored experience, we
also present the results of an evaluation involving real users.”

In: Beaudouin-Lafon, Michel (ed.) Proceedings of the 15th annual ACM symposium on User interface software and technology October 27-30, 2002, Paris, France. pp. 111-120. Available online
“We introduce the Boom Chameleon, a novel input/output device consisting of a
flat-panel display mounted on a tracked mechanical boom. The display acts as a
physical window into 3D virtual environments, through which a one-to-one
mapping between real and virtual space is preserved. The Boom Chameleon is
further augmented with a touch-screen and a microphone/speaker combination. We
present a 3D annotation application that exploits this unique configuration in
order to simultaneously capture viewpoint, voice and gesture information.
Design issues are discussed and results of an informal user study on the device
and annotation software are presented. The results show that the Boom Chameleon
annotation facilities have the potential to be an effective, easy to learn and
operate 3D design review system.”
