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

Supporting decision making process with "Ideal" software agents: what do business executives want?

According to Simon’s (1977) decision making theory, intelligence is the first and most important phase in the decision making process. With the escalation of information resources available to business executives, it is becoming imperative to explore the potential and challenges of using agent-based systems to support the intelligence phase of decision-making. This research examines UK executives’ perceptions of using agent-based support systems and the criteria for design and development of their “ideal” intelligent software agents. The study adopted an inductive approach using focus groups to generate a preliminary set of design criteria of “ideal” agents. It then followed a deductive approach using semi-structured interviews to validate and enhance the criteria. This qualitative research has generated unique insights into executives’ perceptions of the design and use of agent-based support systems. The systematic content analysis of qualitative data led to the proposal and validation of design criteria at three levels. The findings revealed the most desirable criteria for agent based support systems from the end users’ point view. The design criteria can be used not only to guide intelligent agent system design but also system evaluation

Principles in Patterns (PiP) : Project Evaluation Synthesis

Evaluation activity found the technology-supported approach to curriculum design and approval developed by PiP to demonstrate high levels of user acceptance, promote improvements to the quality of curriculum designs, render more transparent and efficient aspects of the curriculum approval and quality monitoring process, demonstrate process efficacy and resolve a number of chronic information management difficulties which pervaded the previous state. The creation of a central repository of curriculum designs as the basis for their management as "knowledge assets", thus facilitating re-use and sharing of designs and exposure of tacit curriculum design practice, was also found to be highly advantageous. However, further process improvements remain possible and evidence of system resistance was found in some stakeholder groups. Recommendations arising from the findings and conclusions include the need to improve data collection surrounding the curriculum approval process so that the process and human impact of C-CAP can be monitored and observed. Strategies for improving C-CAP acceptance among the "late majority", the need for C-CAP best practice guidance, and suggested protocols on the knowledge management of curriculum designs are proposed. Opportunities for further process improvements in institutional curriculum approval, including a re-engineering of post-faculty approval processes, are also recommended

Development of Telephone-based e-Learning Portal

The proliferation of mobile phones in Nigeria, particularly among the student community, has continued to inspire the development and delivery of e-Learning applications. Most of the existing web-based e-Learning applications do not support nomadic voice-based learning (i.e. learning on the move through voice), and consequently do not provide a speedy access to information or enquiries on demand. Internet access is required to get every bit of information from most school portal system, which is not directly available to everyone. Lack of provision for voice in the existing web applications excludes support for people with limited capabilities such as the visually impaired and physical disabilities. In this paper, we present a design and development of a prototype telephone-based e-Learning portal that will be used for course registration and examination. This study is part of an ongoing e-Learning project involving the following modules: enrollment, course registration and examination, enquiries/information, messaging/collaboration, e-Learning and library. The prototype application was developed using VoiceXML for the voice user interface(VUI), PHP for database queries, Apache as the middle-ware and MySQL database as back-end. A unified modelling language (UML) was used to model and design the application. The proposed e-Learning system will compliment the web-based system in other to meet the needs of students with a range of disabilities such as visual impairment, repetitive strain injury, etc, that make reading and writing difficult. It also makes multiple platforms available to all users as well as boosting access to education for the physically challenged, particularly the sight impaired in the developing countries of the world. In institutions where students are not allowed to use mobile phones or where cost is an issue, then the alternative is the use of PC-phone

Reinvigorating the discipline:pervasive computing and tomorrow's computer scientists

Declining enrollments in computer science and related fields are a global concern. This issue's column, by Mike Hazas and Rebecca Marsden of Lancaster University in the UK describes the novel Lancaster Headstart program that uses the excitement of pervasive computing to attract students into the computer science

Evaluating empowerment and control of HE e-learning in a secure environment

With the increased spread of HE distance learning into a wide variety of contexts it is important for us to understand the factors involved in its successful deployment for students. E-learning has a great potential to support effective and empowering HE distance learning (Wilson, 2007; Adams, 2005; Hughes, 2005). However, within two secure environments, prisons and health service, the factors involved are complex. This paper reviews HE e-learning technology perceptions within these two contrasting contexts from 225 students' and stakeholders' perspectives. Previous research has detailed literature limitations on obtaining students' perspectives of e-learning (Conole et al, 2006). These limitations are compounded when other stakeholder perceptions are not integrated (Sun et al, 2007; Adams et al, 2005; Millen at al, 2002). This paper developed and applied an e-learning framework for student and stakeholder perceptions. This social psychological framework, is based on previous practice based e-learning studies and is used here to synthesise two large-scale case studies. The framework focuses on three concepts learner Access (e.g. learning design, technology design, physical access), Awareness (e.g. of resources, their usage and support for e-learning tasks) and Acceptability (e.g. trust, privacy, aesthetics, engagement). Students' and stakeholders' perceptions identified high levels of students' empowerment through e-learning whilst still requiring a further pedagogical tailoring and an awareness of support. However, serious problems within these contexts have identified blocks to e-learning through stakeholders perceptions and fears of acceptability (i.e. issues of risk and trust). Ultimately, through understanding competing perceptions and needs within these complex environments we can support the effective technological development, pedagogical design and deployment of e-learning systems

The Internet of Things Will Thrive by 2025

This report is the latest research report in a sustained effort throughout 2014 by the Pew Research Center Internet Project to mark the 25th anniversary of the creation of the World Wide Web by Sir Tim Berners-LeeThis current report is an analysis of opinions about the likely expansion of the Internet of Things (sometimes called the Cloud of Things), a catchall phrase for the array of devices, appliances, vehicles, wearable material, and sensor-laden parts of the environment that connect to each other and feed data back and forth. It covers the over 1,600 responses that were offered specifically about our question about where the Internet of Things would stand by the year 2025. The report is the next in a series of eight Pew Research and Elon University analyses to be issued this year in which experts will share their expectations about the future of such things as privacy, cybersecurity, and net neutrality. It includes some of the best and most provocative of the predictions survey respondents made when specifically asked to share their views about the evolution of embedded and wearable computing and the Internet of Things
