Our research examines the strategies employed by users during exploratory learning, and what they learn about how a device works and how to accomplish tasks using the device. Initial empirical and modelling work suggests that users typically conduct device-oriented exploration resulting in the acquisition of specifically device-oriented knowledge, but not directly of taskoriented knowledge. Alt...

An increasingly important class of keyword search tasks are those where users are looking for a specific piece of information buried within a few documents in a large collection. Examples include searching for someone’s phone number, the schedule for a meeting, or a package tracking URL, within a personal email collection. We refer to such tasks as “precision-oriented search tasks”. While moder...

This paper describes our ongoing project about a new wheelchair-based rehabilitation robotic system for the disabled, called KARES 11 (KAIST Rehabilitation Engineering Service System Io. We shall concentrate on the issues of design and visual servoing of the robotic arm with three human-robot interaction subsystems: an eyemouse, an EMG interface, and a haptic suit interface. First, the specific...

Bug localization in object oriented program ha s always been an important issue in softeware engineering. In this paper, I propose a source level b u g l o c a l i z a t i o n technique for object oriented embedded programs. My proposed technique, presents the idea of debugging an object oriented program in class level, incorporating the object state information into the Class Dependence Graph ...

We consider a set of real-time periodic tasks where some tasks are preferably executed as soon as possible (ASAP) and others as late as possible (ALAP) while still meeting their deadlines. After introducing the idea of preference-oriented (PO) execution, we formally define the concept of PO-optimality. For fully-loaded systems (with 100% utilization), we first propose a PO-optimal scheduler, na...

Our research aims at building interactive robots and agents that can expand their knowledge by interacting with human users. In this paper, we focus on learning goal-oriented tasks from situated interactive instructions. Learning the structure of novel tasks and how to execute them is a challenging computational problem requiring the agent to acquire a variety of knowledge including goal defini...

Humans have been observed to become disoriented when using menu or hypertext systems. Similar phenomena have been reported by software developers, often manifesting as a feeling of lostness while exploring a software system. To investigate this phenomena in the context of software development, we undertook a field study, observing eight developers of the open-source Eclipse project for two hour...

Traditionally, real-time scheduling algorithms prioritize tasks solely based on their timing parameters and cannot effectively handle tasks that have different execution preferences . In this paper, for a set of periodic real-time tasks running on a single processor, where some tasks are preferably executed as soon as possible (ASAP) and others as late as possible (ALAP) , we investigate Prefer...

the purpose of this study was to investigate the impact of weblog task assessment on iranian efl learners’ reading ability. to this purpose, a group of 30 english language students (both male and female) in rozaneh language institute in najafabad were selected based on their performance on the opt. the researchers tried to select a homogeneous sample in terms of age factor and proficiency level...
