Live & rich tools can support a diversity of domain-specific programming tasks, from visualization authoring to data wrangling. Real-world programming, however, requires performing multiple tasks in concert, calling for the use of multiple tools ...

Text editing is powerful, but some types of expressions are more naturally represented and manipulated graphically. Examples include expressions that compute colors, music, animations, tabular data, plots, diagrams, and other domain-specific data ...

Most interaction with a computer is via graphical user interfaces. These are traditionally implemented imperatively, using shared mutable state and callbacks. This is efficient, but is also difficult to reason about and error prone. Functional ...${}_{\mathsf{}}$

In this study, we extend Fitts’ law to enable it to predict the movement time of pointing operations in interfaces, such as those in navigation bars whose items have different clickable and visual widths and intervals between a target and distractors. ...

GUIs often contain structures that are incidental, not properly manipulatable through well-defined APIs. For example, modifying a list of items in a GUI's model may require extraneous bookkeeping operations in the view, such as adding and removing event ...

When users operate smartphones and desktop interfaces with their fingers, there are differences between the motor and visual widths. For example, when a user selects an item from a vertical menu, the area that is physically touched by the user is often ...

A basic prerequisite for any daily development task is to understand the source code that we are working with. To this end, the source code should be clean. Usually, it is up to us, the developers, to keep the source code clean. However, often there are ...

Today, various Science Gateways created in close collaboration with scientific communities provide access to remote and distributed HPC, Grid and Cloud computing resources and large-scale storage facilities. However, as we have observed there are still ...

Network management software began to evolve in the 70's when network operating systems and the ARPANET raised. Before the invention of graphical user interfaces by Xerox, command line interface (CLI) driven software ruled the world. In terms of usability,...

In terms of usability, network management software based on command line interfaces (CLI) is efficient but error prone. With GUIs, a new generation of security tools emerged and were adopted by young system administrators. Though usability has improved, ...

Layout managers provide an automatic way to place controls in a graphical user interface (GUI). With the wide distribution of fully GUI-enabled smartphones, as well as very large or even multiple personal desktop monitors, the logical size of commonly ...

Graphical User Interfaces (GUIs) have become an important and accepted way of interacting with today's software. Fault localization is considered to be one of the most expensive program debugging activities. This paper presents a fault localization ...

Interaction with computers has become an integral part of daily life for most people. As computing technologies proliferate, simple user interfaces and ease of use become key success factors for a wide range of products. Computer seeks submissions for ...

Mobile phones can persuade users to adopt healthy behaviors such as regular exercise. Monsters & Gold, a context-aware, user-adaptive mobile fitness game, runs on mobile phones to motivate and train users in jogging outdoors. The game dynamically ...

Paper is static, but it is also light, flexible, and robust and has high resolution for reading documents in various scenarios. Digital devices will likely never match paper's flexibility, but they come with all the benefits of computation and ...

The paper presents a Wireless Personal Area Network (WPAN) including two Bluetooth-enabled measuring nodes that delivers information about some physiological parameters extracted from photo-plethysmographic signals and provides information of indoor air ...

This paper examines the influence of two interface characteristics on command selection speed: the integration of command selection with direct manipulation (merging), and two-handed operation. We compared four interaction techniques representing ...

This paper presents a novel approach to modeling and filtering of athetoid motion for use in assistive computer interfaces during targeting tasks such as clicking on icons. Data were recorded from a subject with athetosis during unassisted icon-clicking ...

A domain-specific language for building user interfaces offers a transparent way for programmers to specify interface elements. Microsoft's Extensible Application Markup Language is an XML dialect for this purpose. However, XAML isn't the only choice ...

Many different methods exist for the design and implementation of software systems. These methods may be fully formal, such as the use of formal specification languages and refinement processes, or they may be totally informal, such as jotting design ...
