Collaboration supported by mobile devices has brought advantages for users and also challenges for software developers and mobile computing devices manufacturers. Every kind of device used to support mobile collaboration has strengths and weaknesses depending on the work context where it is used. The idea is to use a specific device when advantages are most(More)
Several researchers in the area of cooperative work take as a success criterion the quality of the group outcome. Nevertheless, recent findings are giving more importance to the quality of " cooperation process " itself. This paper presents the design of a software tool that allow us to capture information concerned with the group work. Besides to reveal(More)

Positive interdependence is the heart of collaborative activities that define collaboration and transform group work into teamwork. To achieve positive interdependence among students, just putting them in group and telling them to work together may not be sufficient. Previously, several types of positive interdependencies have been identified for(More)
An attempt is made to characterize situations in which the use of mobile devices can be useful for the development of collaborative systems. Mobile devices have advantages, such as small size, low cost, portability. They also have disadvantages, such as small viewing screen, little storage capacity, slow processor, unreliable communication facilities. The(More)
In the development of groupware systems a well designed communications infrastructure is required, due to the high complexity of the communication scenario. Also, the design and implementation of coordination and collaboration mechanisms depends on the communications infrastructure. Actually there are no well known guidelines to design this infrastructure.(More)
Collaborative mobile applications support users on the move in order to perform a collaborative task. One of the challenges when designing such applications is to consider the context where they will execute. Contextualized applications are easy to adopt by the users; unfortunately the design of contextualized tools is not evident. This paper presents a(More)
Understanding and analyzing collaborative learning processes require a fine-grained sequential analysis of the group interaction in the context of learning goals. Several researchers in the area of cooperative work take as a success criterion the quality of the group outcome. Nevertheless, recent findings are giving importance to the quality of the(More)
Collaborative applications provide a group of users with the facility to communicate and share data in a coordinated way. Building collaborative applications is still a complex task. In this paper we propose a pattern system to design basic aspects of data sharing, communication, and coordination for collaborative applications. These patterns are useful for(More)
