Zhao, Shengdong, Nakamura, Koichi, Ishii, Kentaro and Igarashi, Takeo (2009): Magic cards: a paper tag interface for implicit robot control. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 173-182. Available online
“Typical Human Robot Interaction (HRI) assumes that the user explicitly interacts with robots. However, explicit control with robots can be unnecessary or even undesirable in certain cases, such as dealing with domestic services (or housework). In this paper, we propose an alternative strategy of interaction: the user implicitly controls a robot by issuing commands on corresponding real world objects and the environment. Robots then discover these commands and complete them in the background. We implemented a paper-tag-based interface to support such implicit robot control in a sensor-augmented home environment. Our initial user studies indicated that the paper-tag-based interface is particularly simple to use and provides users with flexibility in planning and controlling their housework tasks in a simulated home environment.”

Hinckley, Ken, Zhao, Shengdong, Sarin, Raman, Baudisch, Patrick, Cutrell, Edward, Shilman, Michael and Tan, Desney S. (2007): InkSeine: In Situ search for active note taking. In: Proceedings of ACM CHI 2007 Conference on Human Factors in Computing Systems 2007. pp. 251-260. Available online
“Using a notebook to sketch designs, reflect on a topic, or capture and extend creative ideas are examples of active note taking tasks. Optimal experience for such tasks demands concentration without interruption. Yet active note taking may also require reference documents or emails from team members. InkSeine is a Tablet PC application that supports active note taking by coupling a pen-and-ink interface with an in situ search facility that flows directly from a user's ink notes (Fig. 1). InkSeine integrates four key concepts: it leverages preexisting ink to initiate a search; it provides tight coupling of search queries with application content; it persists search queries as first class objects that can be commingled with ink notes; and it enables a quick and flexible workflow where the user may freely interleave inking, searching, and gathering content. InkSeine offers these capabilities in an interface that is tailored to the unique demands of pen input, and that maintains the primacy of inking above all other tasks.”

Zhao, Shengdong, Dragicevic, Pierre, Chignell, Mark, Balakrishnan, Ravin and Baudisch, Patrick (2007): Earpod: eyes-free menu selection using touch input and reactive audio feedback. In: Proceedings of ACM CHI 2007 Conference on Human Factors in Computing Systems 2007. pp. 1395-1404. Available online
“We present the design and evaluation of earPod: an eyes-free menu technique using touch input and reactive auditory feedback. Studies comparing earPod with an iPod-like visual menu technique on reasonably-sized static menus indicate that they are comparable in accuracy. In terms of efficiency (speed), earPod is initially slower, but outperforms the visual technique within 30 minutes of practice. Our results indicate that earPod is potentially a reasonable eyes-free menu technique for general use, and is a particularly exciting technique for use in mobile device interfaces.”

“We present Zone and Polygon menus, two new variants of multi-stroke marking menus that consider both the relative position and orientation of strokes. Our menus are designed to increase menu breadth over the 8 item limit of status quo orientation-based marking menus. An experiment shows that Zone and Polygon menus can successfully increase breadth by a factor of 2 or more over orientation-based marking menus, while maintaining high selection speed and accuracy. We also discuss hybrid techniques that may further increase menu breadth and performance. Our techniques offer UI designers new options for balancing menu breadth and depth against selection speed and accuracy.”

Baudisch, Patrick, Tan, Desney S., Collomb, Maxime, Robbins, Dan, Hinckley, Ken, Agrawala, Maneesh, Zhao, Shengdong and Ramos, Gonzalo (2006): Phosphor: explaining transitions in the user interface using afterglow effects. In: Proceedings of the ACM Symposium on User Interface Software and Technology 2006. pp. 169-178. Available online
“Sometimes users fail to notice a change that just took place on their display. For example, the user may have accidentally deleted an icon or a remote collaborator may have changed settings in a control panel. Animated transitions can help, but they force users to wait for the animation to complete. This can be cumbersome, especially in situations where users did not need an explanation. We propose a different approach. Phosphor objects show the outcome of their transition instantly; at the same time they explain their change in retrospect. Manipulating a phosphor slider, for example, leaves an afterglow that illustrates how the knob moved. The parallelism of instant outcome and explanation supports both types of users. Users who already understood the transition can continue interacting without delay, while those who are inexperienced or may have been distracted can take time to view the effects at their own pace. We present a framework of transition designs for widgets, icons, and objects in drawing programs. We evaluate phosphor objects in two user studies and report significant performance benefits for phosphor objects.”

Zhao, Shengdong and Balakrishnan, Ravin (2004): Simple vs. compound mark hierarchical marking menus. In: Proceedings of the 2004 ACM Symposium on User Interface Software and Technology 2004. pp. 33-42. Available online
“We present a variant of hierarchical marking menus where items are selected using a series of inflection-free simple marks, rather than the single \"zig-zag\" compound mark used in the traditional design. Theoretical analysis indicates that this simple mark approach has the potential to significantly increase the number of items in a marking menu that can be selected efficiently and accurately. A user experiment is presented that compares the simple and compound mark techniques. Results show that the simple mark technique allows for significantly more accurate and faster menu selections overall, but most importantly also in menus with a large number of items where performance of the compound mark technique is particularly poor. The simple mark technique also requires significantly less physical input space to perform the selections, making it particularly suitable for small footprint pen-based input devices. Visual design alternatives are also discussed.”

Schraefel, M. C., Zhu, Yuxiang, Modjeska, David, Wigdor, Daniel and Zhao, Shengdong (2002): Hunter gatherer: interaction support for the creation and management of within-web-page collections. In: Proceedings of the 2002 International Conference on the World Wide Web 2002. pp. 172-181. Available online
“Hunter Gatherer is an interface that lets Web users carry out three main tasks: (1) collect components from within Web pages; (2) represent those components in a collection; (3) edit those component collections. Our research shows that while the practice of making collections of content from within Web pages is common, it is not frequent, due in large part to poor interaction support in existing tools. We engaged with users in task analysis as well as iterative design reviews in order to understand the interaction issues that are part of within-Web-page collection making and to design an interaction that would support that process. We report here on that design development, as well as on the evaluations of the tool that evolved from that process, and the future work stemming from these results, in which our critical question is: what happens to users perceptions and expectations of web-based information (their web-based information management practices) when they can treat this information as harvestable, recontextualizable data, rather than as fixed pages?”
