Building intelligent collaborative interface agents with the ICAGENT development framework

This paper describes the implementation of intelligent collaborative interface agents using the intelligent collaborative agent (ICagent) development framework. In particular, the paper presents the implementation of a collaborative interface agent that acts as a tutor in the context of an educational software application. The agent deliberates socially with users following the SharedPlans model of collaborative activity. Social deliberation requires interface agents to make their desires and intentions clear to the application users, being in constant communication with them, to understand the context of their activity and to reconcile their own and users’ desires in the overall context of action. Reconciliation of users’ desires allows agents to recognize the situations where users need help. The paper briefly presents the ICagent development framework, describes the implementation of the interface agent, and discusses an example of the behavior of the agent during a collaboration session.     

Gaze tutor: A gaze-reactive intelligent tutoring system

We developed an intelligent tutoring system (ITS) that aims to promote engagement and learning by dynamically detecting and responding to students' boredom and disengagement. The tutor uses a commercial eye tracker to monitor a student's gaze patterns and identify when the student is bored, disengaged, or is zoning out. The tutor then attempts to reengage the student with dialog moves that direct the student to reorient his or her attentional patterns towards the animated pedagogical agent embodying the tutor. We evaluated the efficacy of the gaze-reactive tutor in promoting learning, motivation, and engagement in a controlled experiment where 48 students were tutored on four biology topics with both gaze-reactive and non-gaze-reactive (control condition) versions of the tutor. The results indicated that: (a) gaze-sensitive dialogs were successful in dynamically reorienting students’ attentional patterns to the important areas of the interface, (b) gaze-reactivity was effective in promoting learning gains for questions that required deep reasoning, (c) gaze-reactivity had minimal impact on students’ state motivation and on self-reported engagement, and (d) individual differences in scholastic aptitude moderated the impact of gaze-reactivity on overall learning gains. We discuss the implications of our findings, limitations, future work, and consider the possibility of using gaze-reactive ITSs in classrooms.     

An intelligent multimedia interface for fuzzy-logic based inference in crops

The paper reports an interface designed for three subsystems—the knowledge acquisition subsystem with dynamic disease knowledge base, intelligent disease diagnosis subsystem with object-oriented intelligent-inference model and intelligent tutor for crop disease with audio-visual graphical user web-interface. The paper describes the design features; functionality and development of intelligent multimedia web interface. The results of its evaluation are also presented.A novel approach of rule promotion based on fuzzy logic is used in the system for drawing intelligent inferences for crop disease management. A text-to-speech (TTS) converter is used for providing capability of text-to-talking user interface. It provides the highly-effective interactive user interface on web for live interactions. It helps significantly and gives solutions of plant pathological problems in short spell. The application software is built using the Microsoft .NET framework, ASP.NET web-application framework provided in Visual Studio.NET. The Microsoft Speech SDK (5.1) is used to develop text to voice multimedia interface. The dynamic knowledge base is implemented using SQL server.     

A programmed instruction tutoring system for Java™: consideration of learning performance and software self-efficacy

An undergraduate (n=23) and a graduate (n=23) class of information systems majors used a Web-based tutoring system during the first 3-h session of a 14-week course in interface design and implementation. The tutoring system taught a simple Java™ applet as the first technical training exercise, and the instructional design was based upon programmed instruction, which is a competency-based tutoring system. Software self-efficacy was assessed prior to using the tutor and at the end of the 3-h period. Students’ interactive performances (errors and help selections) were recorded for all interfaces in the tutor. The results showed that the undergraduate students made more input and test errors than did the graduate students, but the number of students in each class who completed all eight tutor stages (18 undergraduates and 17 graduates) was almost equivalent. Forty-four of the 46 students completed the fourth tutor stage, which presented frames of information explaining the items in the program. Students who did not complete all eight stages showed more errors on the initial four stages, in comparison to students who did complete all stages. Software self-efficacy increased from pre-tutor to post-tutor occasions for both classes and for both completers and non-completers. No significant relationship was found between software self-efficacy changes and tutor learning performance. Neither was gender related to software self-efficacy changes or learning performance. Evaluations of the tutor were favorable by almost all learners. A competency-based tutoring system may produce both skill and earned self-efficacy at the level of the individual learner, without regard to variations in the learning process leading to mastery.

AFFECT IN TUTORING DIALOGUES

ABSTRACT

This paper is about INES, an intelligent, multimodal tutoring environment, and how we build a tutor agent in the environment that tries to be sensitive to the mental state of the student that interacts with it. The environment was primarily designed to help students practice nursing tasks. For example, one of the implemented tasks is to give a virtual patient a subcutaneous injection. The students can interact multimodally using speech and a haptic device under the guidance of the virtual embodied tutor. INES takes into account elements of the student's character and an appraisal of the student's actions to estimate the mental state of the student. This information is used to plan and execute the actions and responses of the tutor agent.

Natural Language Programming of Complex Robotic BDI Agents

This paper presents a natural language design environment that enables the programming of complex robotic agent systems, comprising of a top level BDI architecture in conjunction with a low level operational system that relates to the hardware interface and supplemental computational processes. The design environment enforces synergy between the development of these traditionally disparate aspects through sharing of ontological information and implementing a form of natural language programming called sEnglish. The resultant system provides an inherent abstraction of defined operational concepts and procedures for agent reasoning and shared meaning between man and machine. Through this shared knowledge the robot’s operational logic and skill execution details are clear to human operators and may thus facilitate the work of design teams to enable rapid prototyping of physical agent systems in simulation or hardware.
