ABOUT POLYGRAF Polygraf system brings universal access to lectures, presentations, business meetings and any other kind of events. Even though the main target group are hearing and visually impaired users, the application can provide in the same time helpful features for all audience. Polygraf enables: 1. to display real-time transcript of speech (speech-to-text reporting, CART service) in user’s hand continuously; 2. to display content of presentation screen in user’s hand with option to attach the transcript of speech as subtitles (closed captions). HOW IT WORKS A professional speech-to-text reporter (CART writer) transcribes real-time spoken word into text using Polygraf Writer application which is another part of Polygraf system (see www.teiresias.muni.cz/polygraf) and the text is broadcasted via a wireless network. In the same time, content of presentation screen provided by a presenter’s computer is captured and broadcasted via the same wireless network as well. This mobile app can receive and display both resources. Note: Establishing both services in parallel is not a requirement; internet connection is not required. WHAT ARE BENEFITS FOR USERS 1. Users can follow the speech-to-text transcript on a mobile device continuously - it allows rather more comfortable and independent use of the speech-to-text service than reading the text from transcriber’s computer or from a central screen in the front; more than one mobile devices can be connected, so more users can follow the transcript in the same time. Features: - view options of the text (font family, size and color, line-spacing) - scroll the text back to display earlier portions of it - basic two-way communication (users can send text messages to speech-to-text reporter) 2. Users can view the content of presentation screen in hand on a mobile device - it brings the legibility of presentations when there is any difficulty to read it from a distance (user’s visual impairment, small size of the presentation, bad light conditions etc.). Features: - view options of the presentation (zoom, color-inverting, B/W scheme) - image refresh rate - option to attach the transcript of speech as subtitles (closed captions) For further information on other parts of Polygraf system, see www.teiresias.muni.cz/polygraf.

Flamenco!

Novelingo presents Flamenco, a video game to learn, enjoy and discover everything about this universal art. Go for it and test your flamenco skills with the musical games! You have seven flamenco “palos” (flamenco styles) in which you can rise to the challenge of nailing the rhythm. You can also create your own with your own drum machine. You’ll find yourself amazed by the stories and anecdotes told by El Piyayo, who will be your guide on this flamenco journey, along with Edgar Neville, Paco and María. They’ll teach you about the earliest origins of flamenco as well as the artists you should know about. But above all, you’ll be immersed in the music. You’ll visit all the corners where flamenco is found, from a tablao to a guitar workshop. And much more! All the music in Flamenco! is original and has come from the guitar of Pepín Naranjo, under the direction of Felipe Milano in the Artesonao studio. Other recordings were recorded at Peña Juan Breva in Malaga and at Susana Martín's workshop. This game has immersive audio thanks to binaural field recordings that reproduce the sound in 360º. The use of headphones is recommended to fully enjoy the experience. Responsible use of headphones with moderate volume level is important to avoid the risk of hearing damage. Flamenco! is an interactive visual novel developed at the Polo Nacional de Contenidos Digitales de Málaga by Novelingo and within the framework of the Tourism Hub of the Diputación de Málaga. This video game has been funded with the collaboration of the European Union and the Ministry of Culture of the Government of Spain through the Recovery, Transformation and Resilience Plan.
