Interfaces in two dimensions, like buttons and menus, are been used for 35 years. Technologies have been developed to extend interfaces for tridimensional environment. One of them, called Augmented Reality, is being viewed due to the ease on interaction with the virtual environment. By other side, due to complexity of human tasks, people are getting together to perform tasks through collaborative...
Recent research on ubiquitous computing has introduced a new concept of activity-based computing as a way of thinking about supporting human activities in ubiquitous computing environment. Existing access control approaches such as RBAC, became inappropriate to support this concept because they do not consider human activities. In this paper, we propose Activity-Oriented Access Control (AOAC) model,...
Bardram introduced a new concept of activity-based computing as a way of thinking about supporting human activities in ubiquitous environments. In such environments where users are using a multitude of heterogeneous computing devices, the need for supporting users at the activity level becomes essential. However, without considering basic security issues, it could be rife with vulnerabilities. Security...
