Models become increasingly important for software development processes. Though there is a multitude of software modeling tools available, the handling of complex UML diagrams is still difficult. In particular, the visualization of a global overview and of logical interrelationships between certain elements arising from refinements of diagrams can be improved. We address these problems and propose the usage of semantic zooming with different levels of detail and describe intuitive interaction techniques to ease the navigation between different diagrams in software models.

This paper presents a novel interactive system for guiding artists to paint using traditional media and tools. The enabling technology is a multi-projector display capable of controlling the appearance of an artist's canvas. This display-oncanvas guides the artist to construct the painting as a series of layers. Our process model for painting is based on classical techniques and was designed to address three main issues which are challenging to novices: (1) positioning and sizing elements on the canvas, (2) executing the brushstrokes to achieve a desired texture and (3) mixing pigments to make a target color. These challenges are addressed through a set of interaction modes. Preview and color selection modes enable the artist to focus on the current target layer by highlighting the areas of the canvas to be painted. Orientation mode displays brushstroke guidelines for the creation of desired brush texture. Color mixing mode guides the artist through the color mixing process with a userinterface similar to a color wheel. These interaction modes allow a novice artist to focus on a series of manageable subtasks in executing a complex painting. Our system covers the gamut of the painting process from overall composition down to detailed brushwork. We present the results from a user study which quantify the benefit that our system can provide to a novice painter. Copyright 2006 acm.

Rapid, early, but rough system prototypes are becoming a standard and valued part of the userinterface design process. Pen, paper, and tools like Flash and Director are well suited to creating such prototypes. However, in the case of physical forms with embedded technology, there is a lack of tools for developing rapid, early prototypes. Instead, the process tends to be fragmented into prototypes exploring forms that look like the intended product or explorations of functioning interactions that work like the intended product - bringing these aspects together into full design concepts only later in the design process. To help alleviate this problem, we present a simple tool for very rapidly creating functioning, rough physical prototypes early in the design process - supporting what amounts to interactive physical sketching. Our tool allows a designer to combine exploration of form and interactive function, using objects constructed from materials such as thumbtacks, foil, cardboard and masking tape, enhanced with a small electronic sensor board. By means of a simple and fluid tool for delivering events to "screen clippings," these physical sketches can then be easily connected to any existing (or new) program running on a PC to provide real or Wizard of Oz supported functionality.

Modern brain sensing technologies provide a variety of methods for detecting specific forms of brain activity. In this paper, we present an initial step in exploring how these technologies may be used to perform task classification and applied in a relevant manner to HCI research. We describe two experiments showing successful classification between tasks using a low-cost off-the-shelf electroencephalograph (EEG) system. In the first study, we achieved a mean classification accuracy of 84.0% in subjects performing one of three cognitive tasks - rest, mental arithmetic, and mental rotation - while sitting in a controlled posture. In the second study, conducted in more ecologically valid setting for HCI research, we attained a mean classification accuracy of 92.4% using three tasks that included non-cognitive features: a relaxation task, playing a PC based game without opponents, and engaging opponents within the game. Throughout the paper, we provide lessons learned and discuss how HCI researchers may utilize these technologies in their work. Copyright 2006 acm.

On the one hand, multi-touch tactile interfaces offer many advantages and are more and more widespread. Their use as 3D application interfaces are rather limited though, since they offer large horizontal flat projection surfaces that are not suited to many kinds of 3D operations. On the other hand, despite the many propositions that have been made over the past years, no single interface has proven to tackle the numerous specificities related to the 3D interaction constraints. Through the CubTile device proposal, our preliminary work tries to bring the strengths related to multitouch tactile surfaces into a device aimed at 3D interactions. Consisting in a medium-sized cube where 5 out of 6 sides are multitouch, our prototype senses several fingers, offers interaction redundancy and lets a user handle 3D manipulation thanks to single handed and bimanual input.

We describe a new system for building Tablet PC-based classroom software. The system, called SLICE, is built for extensibility, using a unique "explicit state" model. Applications developed thus far include presentation, classroom interaction, shared code review, and exam grading. The paper presents an overview of the system and describes these four applications. It then explains the extensibility model, showing how users can add new features.

In this paper we propose an intuitive page-turning and browsing interface of e-books on a flexible e-paper based on user studies. Our user studies showed various types of page-turning actions such as flipping, grasping, and sliding by different situations or users. We categorized these actions into three categories: turn, flip through, and leaf through the page(s). Based on this categorized model, we have developed a conceptual design and prototype of an interface for an e-book reader, which enables intuitive page-turning interactions using a simple architecture in both hardware and software design. The prototype has a flexible plastic sheet with bend sensors, which is attached to a small LCD monitor to physically unite the visual display with a tangible control interface based on the natural page-turning actions as used in reading a real book. The prototype handles all three page-turning actions observed in the user studies by interpreting the bend degree of the *** 2008 acm.

This paper introduces a new low-cost pressure-sensitive user input device called "SqueezeOrb". The device is built from an assembly force-sensing resistors embedded in an elastic hand exerciser. A USB-enabled microcontroller continuously samples the sensors, applies a double-exponential noise-reduction filter and streams the resulting "handgrip strength" measurement to an attached host computer at a frequency of up to 1000 Hz. When combined with optical motion-tracking, the SqueezeOrb becomes a pressure-sensing input device for three-dimensional interaction. Copyright 2008 acm.

This paper introduces ComposAR, a tool to allow a wide audience to author AR and MR applications. It is unique in that it supports both visual programming and interpretive scripting, and an immediate mode for runtime testing. CornposAR is written in Python which means the userinterface and runtime behavior can be easily customized and third-party modules can be incorporated into the authoring environment. We describe the design philosophy and the resulting userinterface, lessons learned and directions for future research.

This work presents a customizable software framework that supports the analysis of correlations between genotype and phenotype within an integrated database in the context of metabolic disorders. The basis for the examination of relations between genotypes and phenotypes is the information from different life science data sources, merged by a mediator-based system in an integrated database. A graphical web interface enables user queries to the integrated data and the trace of connections to corresponding data objects in different information domains. As a result of this work, a web-based prototype of the system is presented. In the context of an example scenario, the framework was used to integrate clinical and molecular biology data for rare metabolic diseases. The framework offers software tools to integrate almost any life science data and to prepare the content for user-specific presentation.
