The article reveals the possibilities of developing and applying adaptive interfaces that involve analyzing user behavior in e-learning systems. Methods of content adaptation based on personalization are a relevant direction in e-learning systems, because they allow taking into account the needs and requirements of users in an automatic mode. A user model is presented, which includes a comprehensive approach to representing both objective (progress indicators, performance, etc.) and subjective parameters (likes, user feedback, etc.), which allows personalizing the material and interface in accordance with individual requests and capabilities of users. The Levenshtein method determines the similarity between user behavior vectors and predefined learning templates, which allows the system to dynamically adjust data presentation scenarios to support the optimal learning trajectory. This method was used in the MS SQL Server online learning system and in a hardware-software complex for learning Braille. Changing the scenarios for displaying materials in accordance with a specific user category demonstrated significant improvements in learning success rates. Experiments showed that automatic switching of scenarios allowed the system to adapt to the level of learning material mastery by the user, which increased motivation and productivity. Each scenario of displaying educational materials provided for different levels of task complexity and depth of presentation of educational material, so changing scenarios during training added interactivity and increased the level of friendliness of the learning environment, which adapted to the pace and style of each user. System load assessment showed that the Levenstein method with minimal use of hardware resources solved the problem of measuring the similarity between user behavior and learning templates, which allows the system to adapt content in real time, taking into account the current productivity, interest and progress of th

Brain-Computer interfaces (BCIs) offer a direct connection between the human brain and digital systems, enabling innovative applications. However, realizing the full potential of BCIs remains challenging due to issues like noise, artifacts, and limited data availability. In this study, we develop a multimodal classifier that integrates electroencephalogram (EEG) and eye-tracking (ET) data to decode user responses to predictive text suggestions. Utilizing an automated feature engineering approach, our pipeline efficiently generates and selects relevant features without extensive manual intervention or deep theoretical insights. Applied to a recent BCI case study involving predictive text input, our method achieved higher classification accuracies compared to traditional approaches. Additionally, it revealed novel insights, such as behavioral patterns where participants did not fully read incorrect predictions and the enhanced performance of multimodal classifiers when combining ICA-preprocessed EEG data with ET data. While automated feature engineering is standard in other domains, it is seldom applied in BCI research. Our findings demonstrate that this approach is a valuable tool for data-driven exploration and the development of competitive single-trial classifiers in novel multimodal BCI paradigms, particularly during the initial stages of research with limited data.

In order to overcome the drawbacks of conventional PDF readers, this article presents DocGenie, a cutting-edge tool that allows for dynamic and interactive document study. DocGenie improves user engagement and accessibility in document-intensive workflows by enabling effective querying, summarization, and contextual interaction through the use of Retrieval-Augmented Generation (RAG) and Google Gemini Pro. The accuracy, efficiency, and user satisfaction of DocGenie surpass those of traditional tools because to the use of cutting-edge techniques including document chunking, FAISS-based embedding storage, and real-time natural language processing. The platform is a major breakthrough in AI-driven document interaction because of its distinctive characteristics, which include multi-document querying, adaptive summarization, and multilingual support. This paper also identifies opportunities for improvement, such as support for a variety of file formats and improved multilingual capabilities, while highlighting DocGenie's potential uses in fields including education, legal research, and digital libraries.
Context: Ensuring smartphone interfaces are usable and accessible is essential for elderly users, particularly those with motor impairments, who face challenges with touchscreen interactions. Problem: Hand tremors and...

Today, more and more data is being stored electronically, requiring systems to be able to save and retrieve large amounts of data efficiently. At the same time, userinterfaces have to satisfy specific quality-of-service requirements. For example, in order to have a multi-media digital library supporting three different kinds of output devices (17 " screens, PDAs, and mobile phones), each user interface has to be programmed separately according to its representation capabilities. This means if the output devices are becoming more advanced, e.g., are colored or have higher resolutions, the interface parameters will change and, in many cases, the quality-of-service requirements too. This results in the userinterfaces having to be amended or sometimes completely rewritten. The same applies when additional devices need to be supported, and they subsequently require new userinterfaces to be built from scratch. Obviously, this is time-consuming and costly. In this paper, we present an approach using XML as the basic technology to semiautomatically derive any kind of user interface for dataintensivesystems.

Application programmers are often unrealistic about the end-user's working environment and seldom cater for the effects of events which will interfere with the use of the application. Such events can disrupt the straightforward execution of a task and interfere with a user's concentration. These events, which will be referred to in this paper as "quirks", could be system breakdowns, various types of interruptions to application use, or human errors. Applications often make no concession to the inevitability of quirks and seldom give assistance in rebuilding mental context afterwards or facilitate understanding of the cause in the case of an error. In addition to the normal quirks caused merely by sharing office space or in working as part of a group of people, most data-intensivesystems are distributed and this tends to precipitate a whole range of errors, hitherto unsuspected, which will probably be reported to the user in all their technical verbosity, reducing the user's understanding of, and confidence in, the system and perhaps necessitating intervention by specialists. The inherent distributed nature of data-intensivesystems also increases the likelihood of breakdowns, since so many more computers are involved in the application than the computer being used by the end-user. Few applications consider the effects of quirks while developing their systems, and the user is therefore unsupported in recovering from them. This paper discusses how applications may be designed to better support users in dealing with the effects of quirks in data-intensivesystems.

The area of data integration has gained increased popularity in recent years. A data browser is described for a data integration system where an intermediate layer of distributed mediators is used to query and integrate data,from heterogeneous data sources. The data sources can be regular relational databases but also other data producing programs. They often have complex data representations and are often object-oriented (DO). The mediator database layer is therefore also object-oriented for a high abstraction level. An OO query interface is used to access the mediator layer from application programs and users. For a scalable and component-based architecture the mediators can be used as servers for other mediators. This leads to a distributed mediator architecture where mediator servers interact with other mediators and data sources. The OO multi-mediator browser GOOVI is presented, which enables maintenance of such distributed mediator databases. With GOOVI all autonomous mediators in a federation can be viewed, queried, and updated. This multi-mediator browser also provides userinterfaces for integrating data through OO views. The paper describes the architecture and functionality of GOOVI.
