T1. From Software Radio to Cognitive Radio: the technical challenges
Jacques Palicot, Supelec, France
In this presentation we will define Cognitive Radio starting from the needs which have motivated this new concept. We will demonstrate that it has developed from natural telecommunication evolution to global convergence of networks and services. Today, for a large number of players in the telecommunication field, this concept consists primarily of intelligently and efficiently managing the spectrum, but we will expand this approach by showing that it can affect all segments of a telecommunications system.
This concept follows the classical circle of intelligent (i.e., sensing the information, analysis, training, decision, action). Some very important technological problems exist in this circle. We will, in particular talk of sensors, which need advance signal processing. The aspect of intelligence management in terms of a software architecture dealing at the same time information from the sensors and decisions (linked with the management of the reconfiguration of equipment), will also be treated. In our vision, Cognitive Radio is supported by Software Radio Technology.
This corresponds to the second main set of problems that we will present. Indeed, all classical problems of Software Radio exist in Cognitive Radio (Front End radio, Non-linearity, hardware, reconfiguration management, etc. We shall not deal in detail all of these issues, but only those that we believe are particularly important shall be discussed."
The presentation will make reference and build on the work carried out by Signal Communications and Electronics embedded (SCEE) SUPELEC team in Rennes Campus
T2. Automatic Generation of Web Interfaces from Discourse Models
Hermann Kaindl, Vienna University of Technology, Austria
Every Web application needs a user interface, today even several ones adapted for different devices (PCs, PDAs, mobile phones). Developing a user interface is difficult, since it normally requires design and implementation. This is also expensive, and even more so for several user interfaces for different devices.
This tutorial shows how human-computer interaction can be based on discourse modeling, even without employing speech or natural language. Our discourse models are derived from results of Human Communication theories, Cognitive Science, and Sociology. Such discourse models can specify an interaction design. This tutorial also demonstrates how such an interaction design can be used for automatic generation of Web interfaces and linking them to the application logic and the domain of discourse (much like in a recently accepted tool demo at IUI’09).
At some of these conferences, I gave a tutorial on Scenario-based Design of User Interfaces. I propose now a more difficult topic. Instead of employing relatively straight-forward usage scenarios, I propose to present the use of discourse modeling for human-computer interaction. The primary benefit from the added structure and content is that user interfaces can be automatically generated by machine, in particular Web interfaces.
A related tutorial to the one proposed here was already given at AAAI’07, HICSS-41 and ICCGI’08, but I have not yet shown the automatic generation of user interfaces live.
Prerequisite knowledge
The assumed attendee background is primarily some interest in designing interactions and user interfaces, especially for Web applications. There are no prerequisites such as knowledge about any of the results of Human Communication theories, Cognitive Science, Sociology, or HCI in general.
