P. Fabian: Methods and tools for presentation of structural information in multimedia documents for visually impaired people

(Grant No. T11C 021 30)

Together with the development of information technologies, the information is increasingly collected and made available in electronic form. This technique makes it more available to all users, in particular visually disabled people (blind or partially sighted). Assisting people with disabilities is being performed with the use of alternative media, such as text, audio and speech. Screen readers read out the text displayed on the screen. This kind of support does not deal well with structural information, for example math formulas, tables and graphs. In this case the structure of information has multiple levels and depends on the context. The interpretation of such information requires a dedicated notation for storing and reading. The goal of the project was to develop principles of representing structural information using XML, so as to be able to present it in a form accessible to people with visual disabilities. Another goal was to develop a prototype browser to read audio information which is simultaneously visually presented. At the same time, the project involved developing a proposal to extend existing notation standards (such as Daisy) covering structural information. Project results can be used in the preparation of educational materials accessible for visually impaired people.

A. Szczęsna: Creating serious games for psychology and psychiatry with simulation actors controlled by scripts

(Grant No. N N518 385337)

In a few last years very fast market development of serious games can be observed. Explicit definition of a serious game is very hard because it depends on application. They are used in education, simulation, research and therapy purposes. In case of serious games the environment dedicated for specific purpose should be as close as possible to reality. The research goal of this project is to work out a new technology of creating serious games, oriented to solving problems with independent simulation actors in virtual reality by using 3D graphics engine with high-level scripting interface. This technology will be used to implement serious game prototype for psychology and psychiatry area. To achive this the research will concern the following fields:

• scripting language which can support programming of independent, autonomous objects in defined environment where they can communicate with each other,

• architecture of graphical engine with scripting interface to control actors and objects on scene,

• concurrent executing of scene objects programmes,

• realistic rendering of tree-dimensional scene in real time, including animation, lighting, GPU programming.

The research will be carried out with using graphical engine FRS, being developed from 2005 in the Institute of Informatics and scripting language Scriptarin. There will be also created a very easy runtime environment for defining scripting programs by psychology and psychiatry doctors.

S. Deorowicz (Investigator): Advanced text algorithms

(MS&HE grant No. N519 317735, Project leader: Z.J. Czech, University of Silesia)

The research within the project is focused on the advanced text algorithms. In particular the problems of determining the longest common subsequence and induction of the context-free grammar are investigated. For both problems the efficient algorithms for solving them will be elaborated. The algorithms are textual in nature, as they process texts (words, subsequences of characters). In the first problem, given the texts the longest common subsequence with some specific features is to be found. A few variants of the basic problems are investigated. The solution to the second problem consists of finding a context-free grammar based on the finite set of words belonging to the language defined by that grammar. Both problems have numerous practical applications, e.g. in bioinformatics, retrieval of music information, linguistics and speech recognition, etc. For both problems instead of serial also parallel algorithms are investigated.

P. Szmal (Investigator), N. Suszczanska (Investigator): Tourism for hearing impaired and its activation possibilities by the use of multimedia tourist information system

(Grant No. N N114 208334, Project leader: A.M. Zajadacz, Faculty of Geography and Geology, Adam Mickiewicz University in Poznan)

To enhance the quality of life for people with hearing impairment there are considered possibilities to prepare and adapt tourist information systems to the specific needs of disabled. To achieve such goal first it is necessary to study and define expectations of potential users of such system. These should be discussed with experts and only then it will be possible to obtain solutions enabling both efficient and attractive presentation and delivery of information using dedicated software and hardware.
