PaperLens is a novel visualization that reveals trends, connections, and activity throughout a conference community. It tightly couples views across papers, authors, and references. PaperLens was developed to visualize 8 years (1995-2002) of InfoVis conference proceedings and was then extended to visualize 23 years (1982-2004) of theCHI conference proceedings. This paper describes how we analyzed the data and designed PaperLens. We also describe a user study to focus our redesign efforts along with the design changes we made to address usability issues. We summarize lessons learned in the process of design and scaling up to the larger set of CHI conference papers.
By modeling users' natural spoken and multimodal communication patterns, more powerful and highly reliable interfaces can be designed that support emerging mobile technology. In this paper, we highlight three diff...

It is a common task when analyzing a large dataset (e.g., census database) to create some kind of overview of the original dataset, which is small enough to be easily manipulated, while remains the key characteristics of the data. Many aggregation techniques have been proposed to help users better understand the dataset and find desired information in it. However, the user can easily get lost after several aggregation operations, since there is rarely mechanism facilitating the user to remember what he or she has done in previous steps. In this paper, we present a prototype, namely MUSA, for multiple-step aggregation visualization. We aimed at designing a tool not only to help users obtain various levels of overviews to narrow their selections, but also to effectively visualize the aggregation processes to enhance the context awareness. We also conducted an informal user study to evaluate the tool.

Knowledge workers use paper extensively for document reviewing and note-taking due to its versatility and simplicity of use. As users annotate printed documents and gather notes, they create a rich web of annotations and cross references. Unfortunately, as paper is a static media, this web often gets trapped in the physical world. While several digital solutions such as XLibris [15] and Digital Desk [18] have been proposed, they suffer from a small display size or onerous hardware requirements. To address, these limitations, we propose PapierCraft, a gesture-based interface that allows users to manipulate digital documents directly using their printouts as proxies. Using a digital pen, users can annotate a printout or draw command gestures to indicate operations such as copying a document area, pasting an area previously copied, or creating a link. Upon pen synchronization, our infrastructure executes these commands and presents the result in a customized viewer. In this paper we describe the design and implementation of the PapierCraft command system, and report on early user feedback. Copyright 2005 ACM.

We present two interfaces to support one-handed thumb use for PDAs and cell phones. Both use Scalable User Interface (ScUI) techniques to support multiple devices with different resolutions and aspect ratios. The designs use variations of zooming interface techniques to provide multiple views of application data: AppLens uses tabular fisheye to access nine applications, while LaunchTile uses pure zoom to access thirty-six applications. We introduce two sets of thumb gestures, each representing different philosophies for one-handed interaction. We conducted two studies to evaluate our designs. In the first study, we explored whether users could learn and execute the AppLens gesture set with minimal training. Participants performed more accurately and efficiently using gestures for directional navigation than using gestures for object interaction. In the second study, we gathered user reactions to each interface, as well as comparative preferences. With minimal exposure to each design, most users favored AppLens's tabular fisheye interface.

This paper presents a multimodal interaction framework for semantic 3D object manipulation in the virtual reality. In our framework, interaction devices such as keyboard, mouse, joystick, tracker, can be combined with speech utterance to give a command to the system. We define an object ontology based on common sense knowledge which defines relationships between virtual objects. By taking into account the current user context and the object ontology, semantic integration component integrates the interpretation result from input manager, and then sends the result to the interaction manager. That result will be mapped into a proper object manipulation. Thus, the system can understand the user intention and assist him for achieving his goal in the handling process, instead of relying entirely on the user's control upon the interaction device and the object, avoiding nonsensical manipulations.

In this paper, the boundary value analysis method for testing case design is generalized for input parameters with constraints. We introduce the definition of priority levels to classify testing cases into three categories. With three input parameters X, Y and Z, we make the general assumptions of Y is a function of X (Y = f(X)) and Z is a function of X and Y (Z = g(X, Y)). The sequence algorithms for test case design are presented and an autogenerator based on the new algorithm is also developed. As a test to the auto-generator, output from the sample runs to NetProvision Activator (NPA), a real world product, is presented and analyzed.
