Want, Roy, Fishkin, Kenneth P., Gujar, Anuj and Harrison, Beverly L. (1999): Bridging Physical and Virtual Worlds with Electronic Tags. In: Altom, Mark W. and Williams, Marian G. (eds.) Proceedings of the ACM CHI 99 Human Factors in Computing Systems Conference May 15-20, 1999, Pittsburgh, Pennsylvania. pp. 370-377.

The role of computers in the modern office has divided our activities between virtual interactions in the realm of the computer and physical interactions with real objects within the traditional office infrastructure. This paper extends previous work that has attempted to bridge this gap, to connect physical objects with virtual representations or computational functionality, via various types of tags. We discuss a variety of scenarios we have implemented using a novel combination of inexpensive, unobtrusive and easy to use RFID tags, tag readers, portable computers and wireless networking. This novel combination demonstrates the utility of invisibly, seamlessly and portably linking physical objects to networked electronic services and actions that are naturally associated with their form.

Moore, Darnell J., Want, Roy, Harrison, Beverly L., Gujar, Anuj and Fishkin, Ken (1999): Implementing Phicons: Combining Computer Vision with Infrared Technology for Interactive Physical Icons. In: Zanden, Brad Vander and Marks, Joe (eds.) Proceedings of the 12th annual ACM symposium on User interface software and technology November 07 - 10, 1999, Asheville, North Carolina, United States. pp. 67-68.

This paper describes a novel physical icon [3] ("phicon") based system that can be programmed to issue a range of commands about what the user wishes to do with handdrawn whiteboard content. Through the phicon's UI, a command to process whiteboard context is issued using infrared signaling in combination with image processing and a ceiling-mounted camera system. We leverage camera systems that are already used for capturing whiteboard content [4] by further augmenting these systems to detect the presence and location of IR beacons within an image. An HDLC-based protocol and a built-in IR transmitter are used to send these signals.

Moran, Thomas P., Saund, Eric, Melle, William van, Gujar, Anuj, Fishkin, Kenneth P. and Harrison, Beverly L. (1999): Design and Technology for Collaborage: Collaborative Collages of Information on Physical Walls. In: Zanden, Brad Vander and Marks, Joe (eds.) Proceedings of the 12th annual ACM symposium on User interface software and technology November 07 - 10, 1999, Asheville, North Carolina, United States. pp. 197-206.

A Collaborage is a collaborative collage of physically represented information on a surface that is connected with electronic information, such as a physical In/Out board connected to a people-locator database. The physical surface (board) contains items that are tracked by camera and computer vision technology. Events on the board trigger electronic services. This paper motivates this concept, presents three different applications, describes the system architecture and component technologies, and discusses several design issues.

Harrison, Beverly L., Fishkin, Kenneth P., Gujar, Anuj, Mochon, Carlos and Want, Roy (1998): Squeeze Me, Hold Me, Tilt Me! An Exploration of Manipulative User Interfaces. In: Karat, Clare-Marie, Lund, Arnold, Coutaz, JoŽlle and Karat, John (eds.) Proceedings of the ACM CHI 98 Human Factors in Computing Systems Conference April 18-23, 1998, Los Angeles, California. pp. 17-24.

This paper reports on the design and use of tactile user interfaces embedded within or wrapped around the devices that they control. We discuss three different interaction prototypes that we built. These interfaces were embedded onto two handheld devices of dramatically different form factors. We describe the design and implementation challenges, and user feedback and reactions to these prototypes. Implications for future design in the area of manipulative or haptic user interfaces are highlighted.

Adler, Annette, Gujar, Anuj, Harrison, Beverly L., O'Hara, Kenton P. and Sellen, Abigail (1998): A Diary Study of Work-Related Reading: Design Implications for Digital Reading Devices. In: Karat, Clare-Marie, Lund, Arnold, Coutaz, JoŽlle and Karat, John (eds.) Proceedings of the ACM CHI 98 Human Factors in Computing Systems Conference April 18-23, 1998, Los Angeles, California. pp. 241-248.

In this paper we describe a diary study of how people read in the course of their daily working lives. Fifteen people from a wide variety of professions were asked to log their daily document activity for a period of 5 consecutive working days. Using structured interviews, we analysed their reading activities in detail. We examine the range of reading activities that our subjects carried out, and then present findings relating to both common characteristics and variation across the sample. From these findings, we discuss some implications for the design of digital reading devices.
