Abstract: A multimedia multimodal dynamic user interface for mobile/wireless devices is introduced in present invention. With this mechanism, service providers can offer rich user oriented applications and they have the freedom to explore new applications easily. A voice call path and a data path are setup for each call request to support the user interface and the device information is sent to a server during the call setup procedure. The user interface offers virtual user to user interaction by integrating multi-media with multi modal interactions. A user may enter inputs through multiple modals and inputs are synchronized and delivered to a server for processing.
