  • Part 1: Historical Settings Reverse
    15 PART 1: HISTORICAL SETTINGS REVERSE ENGINEERING MODERNISM WITH THE LAST AVANT-GARDE Dieter Daniels The concept of an avantgarde, disavowed by postmodern theory, is actually more relevant today than ever before, but it has nothing to do with aesthetics. Only social situations, not artworks, qualify as avantgarde. We need access to alternative experience, not merely new ideas, for we know more about our being than we have being for what we know. Today only metadesign satisfi es the original criteria for avantgarde practice. Gene Youngblood01 THE LAST AVANT-GARDE? The case studies analyzed, documented, and contextualized in the Net Pioneers research project provide a representative cross-section of the creation of Net-based art between 1992 and 1997.02 An entire typology of these new art forms developed in just fi ve years. This astonishing dynamic emerged from the particularly intense meeting and interaction of art history and media history: a rapidly developing, international art found itself racing a fast-changing techno-sociological context.

  • Tip Sheet: Skype Web Chatting Goal: to Successfully Execute Signing Into
    Tip Sheet: Skype Web Chatting Goal: To successfully execute signing into Skype and initiate a web chat with OSU’s College of Agricultural Sciences and Natural Resources (CASNR) Prospective Students Coordinator. Background: Skype allows counselors, teachers and students to engage with the CASNR Prospective Students Coordinator during designated or prearranged times. Skype is another tool for students to ask questions and establish a relationship with the CASNR Prospective Students Coordinator so they can complete the application process and transition to Oklahoma State as smoothly as possible. Request a Skype session with the CASNR Prospective Students Coordinator at http://casnr.okstate.edu/students/future/schedule-a-skype-session. Procedure: • Required equipment: Skype account, webcam, microphone and speakers (be sure you have the correct software and drivers for your devices if they are not functioning properly). • A cell phone app is also available for iOS here and Android here. • If your devices are functioning properly, Skype should recognize your devices automatically and prompt them to operate when you open the program. Skype should then automatically direct you through a short tutorial to test out your webcam’s functionality and audio levels. Signing In/Signing Up: • If you have not yet signed up for Skype, please do so by going to http://www.skype.com and sign up for a free account. With a free Skype account, you have access to plenty of features you can read about here: http://www.skype.com/en/features/. Navigating Skype Desktop Client: After signing in, you will see a ‘Home’ tab (that connects you with your Skype home screen) and a ‘Contacts’ tab.

  • Sign Language Interpreter
    International Journal of Engineering Research & Technology (IJERT) ISSN: 2278-0181 Vol. 3 Issue 5, May - 2014 Sign Language Interpreter Divyashree Shinde1, Gaurav Dharra1,Parmeet Singh Bathija1, Rohan Patil1, M. Mani Roja2 1. Students, Department of EXTC, ThadomalShahani Engineering College, Mumbai, India 2. Associate Professor, Department of EXTC, ThadomalShahani Engineering College, Mumbai, India Abstract –Thesign language interpreter is an interactive system that will recognize different hand gestures of Indian Sign Language and will give the interpretation of the recognized gestures in the form of text messages along with audio interpretation. In a country like India there is a need of automatic sign language recognition system, which can cater the need of hearing and speech impaired people thereby enhancing their communication capabilities, promising improved social opportunities and making them independent. Unfortunately, not much research work on Indian Sign Language recognition is reported till date. The proposed Sign Language Interpreter using Discrete Cosine Transform accepts hand gesture frames as input from image capturing devices such as webcam. This input image is converted to grayscale and resized to 256 x 256 pixels. DCT is Fig.1. Sign language Interpreter then applied to entire image to obtain the DCT coefficients. Recognition is carried out by comparison of DCT coefficient Recognition of a sign language is very important not only of input image with those of the registered reference images in from the engineering point of view but also for its impact database. Database image having minimum Euclidean on the human society [2]. The development of a system for distance with the input image is recognized as the matched translating Indian sign language into spoken language image and the sound corresponding to the matched sign is would be great help for hearing impaired as well as hearing played.
