Humorist Bot: Bringing Computational Humour in a Chat-Bot System
2008
A conversational agent, capable to have a ldquosense of humourrdquo is presented. The agent can both generate humorous sentences and recognize humoristic expressions introduced by the user during the dialogue. Humorist Bot makes use of well founded techniques of computational humor and it has been implemented using the ALICE framework embedded into an Yahoo! Messenger client. It includes also an avatar that changes the face expression according to humoristic content of the dialogue.
Reading skills and children’s navigation strategies in hypertext
2011
Prior research has identified two important navigation strategies that have a clear impact on hypertext comprehension: link selection and overview processing strategies. The first relate to the order in which students select hyperlinks while trying to comprehend a hypertext, whereas the second relate to when and for how long students process navigation overviews, a text device that conveys the text structure by displaying sections, titles and their relations. Most prior research in navigation strategies has been conducted with undergraduate students. We extend prior research by exploring the navigation strategies used by sixth-graders while reading a hypermedia system. We also investigate h…
Visualization and User Interface Questions about Disability
1999
The visually impaired and the intellectually disabled are not equal groups but both groups benefit partly from the same features. Communication, symbols, pictures, customizing and alternative languages are the key elements in visualization and in user interface design to the both groups.
KIND-DAMA: A modular middleware for Kinect-like device data management
2017
Summary In the last decades, we have witnessed a growing interest toward touchless gestural user interfaces. Among other reasons, this is due to the large availability of different low-cost gesture acquisition hardware (the so-called “Kinect-like devices”). As a consequence, there is a growing need for solutions that allow to easily integrate such devices within actual systems. In this paper, we present KIND-DAMA, an open and modular middleware that helps in the development of interactive applications based on gestural input. We first review the existing middlewares for gestural data management. Then, we describe the proposed architecture and compare its features against the existing simila…
Gestural and audio metaphors as a means of control for mobile devices
2002
This paper discusses the use of gesture and non-speech audio as ways to improve the user interface of a mobile music player. Their key advantages mean that users could use a player without having to look at its controls when on the move. Two very different evaluations of the player took place: one based on a standard usability experiment (comparing the new player to a standard design) and the other a video analysis of the player in use. Both of these showed significant usability improvements for the gesture/audio-based interface over a standard visual/pen-based display. The similarities and differences in the results produced by the two studies are discussed
Critical approach to 3D virtual realities for group work
2002
Collaborative virtual environments (CVEs) have been studied extensively during the past few years. In this paper, the concept of virtual reality (VR), and its value for group work are critically examined. To ground the discussions, experiences from a virtual reality project, from 3D chats, and from present CVE applications are analysed in the light of human communication. It is argued that the value of virtual reality is often overemphasised and overrated in the group work context, especially when conce rning desktop virtual realities and generic groupwork without an explicitly defined task or purpose. The main problem with VR is its self-centricity and inadequate support for shared real-li…
The SUMMA Platform: A Scalable Infrastructure for Multi-lingual Multi-media Monitoring
2018
The open-source SUMMA Platform is a highly scalable distributed architecture for monitoring a large number of media broadcasts in parallel, with a lag behind actual broadcast time of at most a few minutes. The Platform offers a fully automated media ingestion pipeline capable of recording live broadcasts, detection and transcription of spoken content, translation of all text (original or transcribed) into English, recognition and linking of Named Entities, topic detection, clustering and crosslingual multi-document summarization of related media items, and last but not least, extraction and storage of factual claims in these news items. Browser-based graphical user interfaces provide humans…
Adaptation of the Presentation in a Multi-tenant Web Information System
2012
We introduced a Web Information System (WIS) adaptation architecture that is based on Software as a Service (SaaS) ideas. It includes adaptation components, which allow adaptation in two levels: the organizations and the users get their own adapted instance of the WIS. The user interface in case of multi-tenancy should be dynamically adapted according to the particular organization and user. The same application component that contains a set of fields, controls and other interface elements should be varied according to the usage context. In this paper we provide a method for adapting the user interface within the proposed adaptation architecture that uses a set of rules describing the seque…
The Logic of User Interface Design
2016
Technical artefacts exist so that people can use them to make something happen. Their capacity to do so depends on the functions and functionalities of the technology, which requires users. Technologies thus have to give users the ability to control them, and the designer’s role is to create the actions and work processes for which the artefacts are intended. This basic HTI pursuit is called user interface design. It applies technical interaction concepts to solve design problems. This chapter presents the overall principles and goals for the user interface design of any technical artefact.
Current communication technologies in language processing
2015
Even the most cutting-edge communication-mediated technology like satellite navigation for orbit positioning, pedestrian movement recognition systems based on inertial sensors, 5G systems, let alone medical devices for coordination of human organs functionality would not be invented without technologies for language processing as an information source between humans and communication systems. Regardless of the way we communicate that is via emails, website short tweets, video conferencing systems, social networking, blogs, instant messaging through websites or mobile applications, or texting only, we use a language that is processed by computer system. Thus, the keynote paper discusses lang…
