Toward user oriented semantic geographical information systems
User Oriented Geographical Information Systems, a recent adaptation of classical GIS concepts to everyday usage, are becoming more and more present in the web landscape. Recent developments show the need of adding higher semantic levels to the existing frameworks, to improve their usage, as well as to ease scalability. We point out limits of actual examples, related to handling heterogeneous data, scalability issues, and expressiveness, and suggest a framework for building a Semantic User Oriented GIS. Notably this framework aims to address the peculiarities of the geographical space domain, and to offer a cognitively sound interface to the user
Mining usage data for adaptive personalisation of smartphone based help-on-demand services
The file attached to this record is the author's final peer reviewed version. The Publisher's final version can be found by following the DOI link.Mobile computing devices and their applications that encompass context aware components are becoming increasingly more prevalent. The context-awareness of these types of applications typically focuses on the services offered. In this paper we describe a framework that supports the monitoring and analysis of mobile application usage patterns with the goal of updating user models for adaptive services and user interface personalisation. This paper focuses on two aspects of the framework. The first is the modelling and storage of the usage data. The second focuses on the data mining component of the framework, outlining the five different capabilities of the adaptation in addition to the algorithms used. The proposed framework has been evaluated through specific case studies, with the results attained demonstrating the effectiveness of the data mining capabilities and in particular the adaptation of the User Interface. The accuracy and efficiency of the algorithms used are also evaluated with three users. The results of the evaluation show that the aims of the data mining component were achieved with the personalisation and adaptation of content and user interface, respectively
Learning from Interaction: User Interface Adaptation using Reinforcement Learning
The continuous adaptation of software systems to meet the evolving needs of
users is very important for enhancing user experience (UX). User interface (UI)
adaptation, which involves adjusting the layout, navigation, and content
presentation based on user preferences and contextual conditions, plays an
important role in achieving this goal. However, suggesting the right adaptation
at the right time and in the right place remains a challenge in order to make
it valuable for the end-user. To tackle this challenge, machine learning
approaches could be used. In particular, we are using Reinforcement Learning
(RL) due to its ability to learn from interaction with the users. In this
approach, the feedback is very important and the use of physiological data
could be benefitial to obtain objective insights into how users are reacting to
the different adaptations. Thus, in this PhD thesis, we propose an RL-based UI
adaptation framework that uses physiological data. The framework aims to learn
from user interactions and make informed adaptations to improve UX. To this
end, our research aims to answer the following questions: Does the use of an
RL-based approach improve UX? How effective is RL in guiding UI adaptation? and
Can physiological data support UI adaptation for enhancing UX? The evaluation
plan involves conducting user studies to evaluate answer these questions. The
empirical evaluation will provide a strong empirical foundation for building,
evaluating, and improving the proposed adaptation framework. The expected
contributions of this research include the development of a novel framework for
intelligent Adaptive UIs, insights into the effectiveness of RL algorithms in
guiding UI adaptation, the integration of physiological data as objective
measures of UX, and empirical validation of the proposed framework's impact on
UX
A FRAMEWORK FOR INTELLIGENT VOICE-ENABLED E-EDUCATION SYSTEMS
Although the Internet has received significant attention in recent years, voice is still the most convenient and natural way of communicating between human to human or
human to computer. In voice applications, users may have different needs which will require the ability of the system to reason, make decisions, be flexible and adapt to
requests during interaction. These needs have placed new requirements in voice application development such as use of advanced models, techniques and methodologies which take into account the needs of different users and environments. The ability of a system to behave close to human reasoning is often mentioned as one of the major requirements for the development of voice applications.
In this paper, we present a framework for an intelligent voice-enabled e-Education application and an adaptation of the framework for the development of a prototype Course Registration and Examination (CourseRegExamOnline) module. This study is a preliminary report of an ongoing e-Education project containing the following modules: enrollment, course registration and examination, enquiries/information, messaging/collaboration, e-Learning and library.
The CourseRegExamOnline module was developed using VoiceXML for the voice user interface(VUI), PHP for the web user interface (WUI), Apache as the middle-ware and MySQL database as back-end. The system would offer dual access modes using the VUI and WUI.
The framework would serve as a reference model for developing voice-based e-Education applications. The e-Education system when fully developed would meet the
needs of students who are normal users and those with certain forms of disabilities such as visual impairment, repetitive strain injury (RSI), etc, that make reading and
writing difficult
A Framework for Computational Design and Adaptation of Extended Reality User Interfaces
To facilitate high quality interaction during the regular use of computing
systems, it is essential that the user interface (UI) deliver content and
components in an appropriate manner. Although extended reality (XR) is emerging
as a new computing platform, we still have a limited understanding of how best
to design and present interactive content to users in such immersive
environments. Adaptive UIs offer a promising approach for optimal presentation
in XR as the user's environment, tasks, capabilities, and preferences vary
under changing context. In this position paper, we present a design framework
for adapting various characteristics of content presented in XR. We frame these
as five considerations that need to be taken into account for adaptive XR UIs:
What?, How Much?, Where?, How?, and When?. With this framework, we review
literature on UI design and adaptation to reflect on approaches that have been
adopted or developed in the past towards identifying current gaps and
challenges, and opportunities for applying such approaches in XR. Using our
framework, future work could identify and develop novel computational
approaches for achieving successful adaptive user interfaces in such immersive
environments.Comment: 5 pages, CHI 2023 Workshop on The Future of Computational Approaches

A user-centred personalised e-learning system
The paper proposes a framework for understanding the factors that affect usability of e-learning. The framework can be applied to the development of (1) a formative usability evaluation method for e-learning systems and (2) personalisation rules for e-learning systems interface. The formative usability evaluation method is intended for the evaluation of e-learning systems during its development stages, from screen-based prototypes to near completion. The evaluation criteria will be customisable depending on contingent criteria such as user characteristics and e-learning system characteristics. A web-based prototype will be developed to allow the convenient implementation of the methodology. The personalisation rules for e-learning system is intended for the automatic adaptation of e-learning systems' interface to different users' preferences in order to maximise its usability and learnability for individual users
Public Sound Objects : a shared environment for networked music practice on the Web
The Public Sound Objects (PSOs) project consists of the development of a networked musical system, which is an experimental framework to implement and test new concepts for online music communication. The PSOs project approaches the idea of collaborative musical performances over the Internet by aiming to go beyond the concept of using computer networks as a channel to connect performing spaces. This is achieved by exploring the internet’s shared nature in order to provide a public musical space where anonymous users can meet and be found performing in collective sonic art pieces. The system itself is an interface-decoupled musical instrument, in which a remote user interface and a sound processing engine reside with different hosts in an extreme scenario where a user can access the synthesizer from any place in the world using the World Wide Web. Specific software features were implemented in order to reduce the disruptive effects of network latency, such as dynamic adaptation of the musical tempo to communication latency measured in real time and consistent sound panning with the object’s behavior at the graphical user interface
Adaptive data communication interface: a user-centric visual data interpretation framework
In this position paper, we present ideas about creating a next generation framework towards an adaptive interface for data communication and visualisation systems. Our objective is to develop a system that accepts large data sets as inputs and provides user-centric, meaningful visual information to assist owners to make sense of their data collection. The proposed framework comprises four stages: (i) the knowledge base compilation, where we search and collect existing state-of-the-art visualisation techniques per domain and user preferences; (ii) the development of the learning and inference system, where we apply artificial intelligence techniques to learn, predict and recommend new graphic interpretations (iii) results evaluation; and (iv) reinforcement and adaptation, where valid outputs are stored in our knowledge base and the system is iteratively tuned to address new demands. These stages, as well as our overall vision, limitations and possible challenges are introduced in this article. We also discuss further extensions of this framework for other knowledge discovery tasks
