Fine-Grained Adaptive User Interface for Personalization of a Word Processor: Principles and a Preliminary Study

We introduce novel fine-grained adaptive user interface for the OpenOffice.org Writer word processor. It provides a panel container with personalized user interface to an individual user. The personalization is provided on frequently or recently used user commands, user’s preferred interaction styles and frequently used parameters to user commands. The next part of the paper describes a proof-of-concept usability study. We measured task completion times and error rates on the proposed adaptive interface, menus and toolbars on a word processing task.

Cloud-based security research testbed: A DDoS use case

In this paper we present a cloud-based research testbed designed to aid network security managers. The testbed enables operators to emulate various network topologies, services, and to analyze attacks threatening these systems. A possibility to test results of network management measures is desired, since testing these measures in a production environment is always not possible. We demonstrate a testbed use case, which aids to scrutinize network behavior under attack. Our use case is based on a large DDoS attack which targeted network infrastructure and web servers in Czech Republic in March, 2013.

A research framework for performing user studies and rapid prototyping of intelligent user interfaces under the OpenOffice.org suite

We introduce a research framework which enables to use the OpenOffice.org as a platform for HCI research, particularly for performing user studies or prototyping and evaluating intelligent user interfaces. We make two contributions: (1) we introduce an innovative hybrid logging technique which provides high-level, rich and accurate information about issued user commands, command parameters and used interaction styles. Our logging technique also avoids an unwanted requirement for further complex processing of logged user interface events to infer user commands, which must be performed on most loggers these days. (2) Our logging tool acts as a component object in OpenOffice.org with an easy-to-use Application Program Interface (API) which enables, along with deep OpenOffice.org programmability, to use OpenOffice.org as a research framework for developing and evaluating intelligent user interfaces.

Adaptive User Interface Personalization in ERP Systems

Enterprise Resource Planning (ERP) systems had grown into complex applications integrating various processes and large amounts of data in detail. Such complexity negatively impacts usability owing to providing single static user interface that should meet users with diverse roles, tasks and requirements. In this paper we introduce a concept of adaptive user interface personalization in the SAP ERP system. We address two important aspects of personalization; (1) personalization to the user’s prominent tasks, (2) personalization of individual on-screen task forms using adaptive progressive disclosure with ephemeral visualization. In the next we describe a mock-up of our adaptive system in detail and results of brief questionnaire study.

KYPO: A Tool for Collaborative Study of Cyberattacks in Safe Cloud Environment

This paper introduces the KYPO --- a cloud-based virtual environment faithfully simulating real networks and enabling users to study cyber attacks as well as to train users in isolated and controlled environment. Particularly, the paper focuses on the user environment and visualizations, providing views and interactions improving the understanding of processes emerged during experiments. Web user interface of the KYPO system supports several collaboration modes enabling the participants to experiment and replay different types of security related tasks.

A Hybrid Approach to User Activity Instrumentation in Software Applications

This paper introduces novel approach to logging user activity in software applications that provide accurate high-level information about issued commands, commands parameters and user interaction styles without a need for inferring user activity from logged user interfaces events as it is required on most loggers these days. We also demonstrate the proposed approach on a prototype implementation under the OpenOffice.org suite.
