The Sprint Essistant: Interactive Services Through a Natural UI James Schumacher [email protected] January 2002 Sprint Advanced Technology Laboratories Burlingame, California Advanced Technology Laboratories The Sprint Essistant A federated system of loosely coupled services made cohesive through an innovative multi-modal interface. Leveraging such components as animated agents and Text to Speech engines, the Essistant enables the user to make a personalized connection to the services. Advanced Technology Laboratories What is the Essistant? Not the desktop Ubiquitous computing Smart House / Smart Space Pervasive Computing Speech & Transparent User Interfaces Advanced Technology Laboratories LAN as Client Federated Services Backend Services feed the LAN LAN as intermediary LAN Services function autonomously Advanced Technology Laboratories The LAN & Connectivity “Broadband is five years away.” Long live narrowband (DSL & Cable) Down rates average ~400kb/s Leveraging “Always On” Fat Content Over Skinny Pipes Keep Data Flowing. Maximize the use of narrowband. Advanced Technology Laboratories Fat Content over Skinny Pipes Assumptions: • • • • • Typical broadband connectivity is 0.3 -1.5 Mbps. BW bottlenecked pipes not necessarily at the last mile. Multimedia content (mostly video) is emerging. High percentage of multimedia content is stored. Most of multimedia content is currently encoded/delivered at a constant bitrate. • Broadcast quality content > 1.5Mbps Can this content be sent over a slow pipe? Advanced Technology Laboratories Fat Content over Skinny Pipes LAN utilization of fat content: • • • • Active Prefetched media Video-on-demand Purchase of multi-media (Music, DVDs, etc) Rich media web sites pre-cached.

Not just faster web pages Entertainment, Cable TV, VOD. Telephony and VoIP Advanced Technology Laboratories Enabling Tech: Mobile Bandwidth Network is always with you Mobile, G3 connectivity Connectivity to home LAN from anywhere Advanced Technology Laboratories Generic Architecture Agent Preference database Intelligent Agent Network Provider User-Agent Net-Agent Databases AI User-Network Home User Prefs User-Agent User-Network Mobile User Advanced Technology Laboratories Enabling Tech: Artificial Intelligence Speech Recognition Natural Language Processing Chatter-Bots (ALICE) Profiling, and auto preferences Semantic Web & Ontologies Inference Engines (e.g Cycorp) Advanced Technology Laboratories Use of AI to predict user requirements Wide availability of AI engines. AI capabilities have increased, cost has decreased significantly. Ideally suited to alter the form of interfaces to the network based on user requirements and user input. Advanced form of user profiling and personalization. AI predictions may alter the network usage and its patterns considerably. Advanced Technology Laboratories Current Trends: Personalized Interactive Services Goal: • Development of a distributed network and client-aware interactive system which integrates and delivers personalized content and services to users in a seamless manner through agent technology and network-based user information. Adds value by: • • • • Personalizing content. Personalizing interaction. Seamlessly introducing new services. Allowing accessibility by different devices/networks (PCS, broadband, etc.). • Providing for targeted advertisement. Advanced Technology Laboratories Enabling Technology: Animation & 3D Three dimensional displays Three dimensional cameras Dynamic real-time animation Advanced Technology Laboratories Live 3D capture technologies Z-Cam Advanced Technology Laboratories 3D Display Technology Stereoscopic monitors Multi-planar monitors Advanced Technology Laboratories Robotics and Physical Presence Capabilities of robots have increased at a much lower cost Virtual Presence • Virtual Telecommuter • Human/Robot remote collaboration (POP troubleshooting…) • Users can have a physical presence Advanced Technology Laboratories Robotics and Physical Presence (cont’d) Advanced Technology Laboratories MPEG-4 Applicability Emerging international standard for delivery of multimedia traffic. Provides: • Delivery of all known media types over any transport mechanism (IP, ATM, RTP, MPEG-2 Transport Stream, etc.). • Scene coherency and synchronization. • Scalability due to bandwidth (BW) or client device limitations. • Interactivity with 3D objects and object-based compression and delivery. • Encode-once/use-everywhere content.
