Every operating system has an underlying graphical user-interface that it supports. The graphical user-interface under UNIX is X-Windows. X-Windows has a rich and historical origin with capabilities that other GUI packages do not support. X-Windows is an important graphic tool; other tools exists that compliment X-Windows based development in one way or another. The technology behind X-Windows ...

Interactive machine learning (IML) is proposed to train intelligent systems. This paper proposes a new approach to solve the feedback delay and low visibility problem of conventional IML handling large-scale data. The approach features high-speed feedback using an approximate nearest neighbor, process controllability by the user, and priority based visualization. The validity of the approach is...

This paper describes an empirical study of end-users that tested the usability of The Programmers’ Playground graphical environment. The Programmers’ Playground is a software library and run-time system for constructing distributed multimedia applications. Playground’s graphical environment enables end-users to create direct manipulation graphical user interfaces (GUIs) and to dynamically confi...

Gambal is an information retrieval system for indexing and accessing web pages that includes graphical interfaces to ease web page search and accessing. In particular, the interfaces provide the user with tools for navigating through hierarchies of documents and visualize selected documents and similar ones. Here, similarity is either based on Wordnet 1.7 or Latent Semantics Analysis. Graphical...

In this approach, two basic services designed for the engineering of computer based systems (ECBS) are combined: a symbol-oriented man-machine-service and a high speed database-service. The man-machine service is used to build graphical user interfaces (GUI’s) for the database service; these interfaces are stored using the database service. The idea is to create a GUI-builder and a GUI-manager ...

Status updates on social networking sites are prolific. Literature in psychology suggests communicating personal status to oneself, and within a group, has benefits. We present different input (capture) and output (representations) of multi-dimensional wellbeing statuses, discuss quantitative and qualitative findings of an evaluation of the interfaces, and propose a course of work for future st...

Human–machine-interaction studies complex communication and interaction principles between people and computers. HMI research is concerned with a wide field of related topcis covering the realisation, evaluation of interactive machine and computing systems. It furthermore covers knowledge representation, displaying techniques, signal processing, pattern recognition, human factors, haptics and r...

While providing non-visual access to graphical user interfaces has been the topic of research for over 20 years, blind users still face many obstacles when using computer systems. The higher degree of flexibility for both developers and users poses additional challenges. Existing solutions are largely based on either graphical toolkit hooks, queries to the application and environment, scripting...

Computer graphics is used in many fields of computer science, ranging from the presentation of user interfaces to the visualization of scientific aspects. These application areas are extended by techniques for animation and for interacting with the content, based on the description by markup languages. This thesis proposes new methods and strategies for standardized markup languages for user in...
