High-level system architecture for the delivery of dynamic IVVR (Interactive Voice & Video Response) services

Commercially available IVVR appliances [For example, DTG 3000 from Dilithium is a combination of MCU (Multipoint Control Unit), 3G-324M Gateway, and transcoder] still focus on dialog-based services and use VoiceXML to create IVVR applications that are generally IVR (Interactive Voice Response) Supplements, without sophisticated features like real-time video generation or camera-based interaction. This hinders the creation of advanced IVVR applications as mentioned in Section 4. Such applications are generally founded on pre-recorded or pre-generated video sequences that are played back based on speech commands or keystrokes. To create a more flexible solution that is capable of delivering games and interactive services, sounds, and graphics need to be generated in real time. The current research and testing results recommend the configuration featured in the figure on the left.

Adobe Flex has evolved into a suite of technologies appropriate for the creation of rich media applications and games. For the solution presented in this research, Flash is employed as the Game Engine as it is very flexible and can be extended to create 3D games [By using the open source real-time 3D Engine Papervision3D]. The Flash application is not run on a handset, but the audio and video it creates are transmitted over a 3G-324M session to a handset so they can be controlled based on the handset

Download my A-graded thesis. Abstract: Interactive voice and video response (IVVR (Interactive Voice & Video Response)) is a mobile technology enabling interactive services based on 3G video telephony. IVVR applications can take advantage of bidirectional real-time multimedia streaming, enabling speech and camera-based interaction. Games are a proven way to draw users into new technologies. This thesis analyses IVVR

Especially in multiplayer scenarios, game developers need to discover ways to provide players with the freedom to interrupt a game without displeasing other players. Further, game concepts should cope with the interaction delays of IVVR (Interactive Voice & Video Response) technology. In single-player games, the game should automatically pause and save the current game state when a user hangs-up the video call, resuming the last game state when the user chooses to play again. Implementing a similar functionality in multiplayer games is more challenging. As real-time shooters require rapid interaction, they are inappropriate for the W-CDMA (Wideband Code Division Multiple Access) network. One way to cope with the high 3G network latency is turn-based multiplayer games in which fast reactions to other players

Getting the MWC mobile guide for your phone is a good idea to prepare for the congress while your flight to Barcelona and in order to avoid carrying the printed catalog on site. I noticed a problem with the installation page http://whatamap.com/mwc/install/.It says that you should access this page with your mobile for downloading the mobile guide. With my WM 6.5 device and Opera or Internet Explorer that does not work, unfortunately. It still says “You have arrived on the MWC 2010 mobile guide installation page with a desktop browser”. By using an user agent switcher for my Firefox I found out the correct link. There is only a Java-Version available, though: http://whatamap.com/mwc/s60/MWC2010.jad

Downloading the native Windows Mobile app

1. Search for MWC 2010 in Windows Marketplace application
2. Install the app via Windows Marketplace
3. It will appear in your phone menu

Update

I cannot find the mobile guide in the mobile marketplace by using “MWC 2010″ on my mobile. On the marketplace website it is not available as well: http://www.microsoft.com/windowsmobile/catalog/cataloghome.aspx?bin=1&device=0&os=0.
