As more and more travelers wish to create their personalised trip itineraries, the provision of geographical information and services on travel websites is an unavoidable necessity. The evolution of geoportals, geocollaborative portals and web 2.0 present numerous opportunities and services for making the trip planning process less complex and time consuming, more efficient and more social and ...

Navigation modules are capable of driving a robotic platform without direct human participation. However, for some specific contexts, it is preferable to give the control to a human driver. The human driver participation in the robotic control process when the navigation module is running raises the share control issue. This work presents a new approach for two agents collaborative planning usi...

Mental models are cognitive structures, which are built to understand certain aspects of the real world. Planning and control of human activity are based on them (cf. Johnson-Laird 1980; Dutke 1994). Learning a computer application goes along with the development of appropriate mental models (Norman 1983; Dutke 1994). To support users in building up mental models, computer applications and thei...

When different members of a work group develop their own individual plans, or sets of tasks to achieve desired goals, there may be conflicting and synergistic interactions among these plans. Conflicts may arise when one task negates the effect of another task, or two tasks compete for the same resource. Synergies may arise if the desired effects of some tasks are also accomplished by other task...

Contemporary and near-future military coalition environments present a number of challenges for military planning. Not only must military planners create plans against a backdrop of strict time constraints and uncertain information, they must also coordinate their planning efforts with other planning staff (often from different organizational, linguistic and cultural communities). This paper ex...

Nowadays, enterprises cooperate more extensively with other enterprises during the entire product life cycle. Temporary alliances between various enterprises emerge such as those in Virtual Enterprises. Collaborative applications are demanded that enable enterprises to engage in such endeavors. This paper aims to present a framework with which collaborative applications can be characterized and...

Cooperative game is an approach for a group of decision-making agents (DMAs) to reach mutually beneficial agreements where the players make agreements in order to optimize their common cost or payment. A coordination mechanism is required to achieve a rational and structured plan for a decision jointly made by independent DMAs. This paper presents a cooperative game for the problem of collabora...

Computers enhance education in some important ways, but they may have unintended consequences for teaching and learning. Using undergraduate education in urban and regional planning as a case study, this paper examines how computers affect interests (what we think about), symbols (what we think with), and community (the forum in which thoughts develop). The primary critique is that computer app...

Th is paper describes a pilot study for an alternative design process by integrating a designer-user collaborative session with digital models. Th e collaborative session took place in a 3D AutoCAD class for a real world project. Th e 3D models served as an interface for designer-user collaboration during the design process. Students not only learned how to use 3D AutoCAD, but also experienced ...
