  Yahoo Query Language (YQL)
  YQL is a web service that allows developers to access, transform, update and mashup any data on the web using a simple SQL-style language. YQL's server-side Javascript enables developers to perform complex data transformation and move their application logic on Yahoos infrastructure and cloud storage. An open plugin architecture enables anyone to create new data sources and run code in YQL and access it globally. An interactive console helps developers interactively explore the data table sources and develop queries.

  Pipes
  Pipes is a service platform for processing well-structured data such as RSS, Atom and RDF feeds in a Web-based visual programming environment. Developers can use Pipes to combine data sources and user input into mashups without having to write code. These mashups, analagous in some ways to Unix pipes, can power badges on personal publishing sites, provide core functionality for existing or new Web applications, or serve as reusable components within the Pipes platform itself

  Mixd
  Mixd was a mixed mobile, email and web system that allows users to set up groups and text or share photos within those groups regardless of device or communication method. The system required several session management layers over SMS, email and the web to track and forward messages across different groups without requiring a user to explicitly name the group when replying.

  Local Event Browser
  A completely client-side demo of many Yahoo! APIs, created for the launch of the Yahoo! AJAX maps API. The map acts as the center of the experience and your browse movement on the maps viewport determines the events fed into the application. These appear on the map, a detail list, a tag cloud and a calendar - all of which dynamically change as the map is dragged.

  DoKumobility
  DoKumobility is a service-oriented architecture that standardizes access to any type of document source provider and applies a pluggable set of web services to those files. The distributed and loosely- coupled nature of the system lends itself naturally to supporting mobile document-centered work. The end user experience is selecting a document from any source service and applying another service to it. DoKumobility enabled mobile users to manage, print, and share documents no matter where they are.

  AnySpot
  AnySpot provides a web service platform for ubiquitous access to any file and folder and the ability to share them on an ad-hoc basis. The core features are:
  • Rapid access to the current versions of the files you need from anywhere at any time: history tracking allows quick retrieval of recently accessed documents
  • Seamless file and folder sharing without having to move them to special locations: enabling seamless and immediate creation of extra-nets or sharing cached versions of large files on your office machine
  • Integration with existing document services, such as NetPrint and InterFax.
  The system provides numerous methods of access, including a task-based multi-lingual web interface, a phone interface for most web-capable cell phones, and a WebDAV protocol handler to enable remote editing and browsing from applications like MS Office. AnySpot's web services architecture enables pluggable file sources to connect the core mid-tier to any file system (Standalone PCs, Linux/Unix, PC domains etc) while a similarly pluggable security model enables authentication against most common security providers (Radius, LDAP etc), providing single sign on if desired. AnySpot was based on an earlier conceptual prototype (PIPs) and re-architected to a more product-level system supporting a wide variety of real networks and security schemes found in more realistic customer environments. The current version has been released to many groups within Fuji Xerox, and will be integrated into one core FX product and distributed to tens of thousands of customers.

  Video Guestbook
  FXPAL's Video Guestbook promotes organizational knowledge and awareness of corporate visitors. The capture component of the system includes an agent-based conversational interface running on a touch screen display (to greet visitors), a business card scanner (to capture visitors' details), a video camera (to capture visitors' faces) plus microphone (to capture pronunciation of visitors' names). After visitor data has been captured, a recommender bar in Outlook or Internet Explorer presents matching contact results based on the current content in a manner that does not disrupt their tasks, but which allows them to access contact details with a single interaction.

  SwapDV
  The SwapDV project took an existing set-top PVR/DVR (Replay) and attempted to extend it's capabilities to promote 'community channels', where family and friends could subscribe and download the latest videos of their children and watch them on their set-top box through a peer-2-peer network. The project became FXPAL's first Open Source project which I continued to direct. It attracted several external developers and the software gained over 3000 downloads in just 2 months with 20,000 web hits. The software was featured on several popular technology community web-sites such as slash.org.

  PIPs
  The Personal Interaction Points research system combines users' networked resources or 'personal information clouds'ówith device-specific user interfaces for performing common tasks on shared document devices such as projectors, public displays, and multi-function copiers. We developed and compared personal interfaces that are embedded (i.e., integrated or co-located with the shared device) versus portable (i.e., accessible via portable devices such as mobile phones or PDAs). The application integrated with the NT domain security model to seamlessly impersonate a user at a remote device and connect to their desktop resources (by extracting their encrypted password from an RFID card).

  M-Links
  The M-Links system created a real world ubiquitous information system using the most pervasive content, devices, and networks: namely the Web, mobile phones, and mobile phone networks. M-Links used a Java servlet middleware proxy system to process web pages and provide the user with a list of links (and other entities like phone numbers and addresses) from that page which they could dig through in the same way they might dig through folders on their desktop to locate files. When users find a useful link, M-links connects them with a set of appropriate services, analogous to right clicking on a document and using the context menu on a desktop. For instance, a user can navigate to a PDF document link and e-mail the PDF (or URL) to himself for later use at the desktop by selecting the link and applying the e-mail service.

  Media Note
  Media Note enabled users of WAP phones, smart pagers (RIM) and Palm devices to access and collaborate over normal documents and web page (via any appropriate device 'to hand') using shared comments t over regions of documents (like paragraphs Word). Comments could be recorded in a wide variety of media (appropriate to the device being used - text, voice, scribbles) which could be transcoded as necessary for rendering to any type of output device. The system allowed user's to dynamically couple and de-couple devices in the environment with themselves (so if the user forgot their cell phone they could use a nearby public phone) as well as plug-in new MIME-MIME transcoders and device profiles.

  Abstract CVE library demonstrator
  The demonstrator provided a 3D interactive system for users to enter and display queries on a remote library database. The system employed various novel techniques for navigating and interacting within an abstract data environment and made use of several sorting and force-displacement algorithms to place the results in the environment. The system employed a clustering algorithm to collect 'common' hits together in the space to form 'clouds' and users could define how these clusters are formed based on various criteria weightings. The system was used in several public venues.

  Anchored Conversations "Sticky Chat"
  The application allowed chat spaces such as IRC channels and ICQ chats to be loosely attached like Post-It notes to a wide variety of applications, including MS Word, PowerPoint and Internet Explorer. Sticky chats could be moved between applications, or re-attached elsewhere in the document easily. Once a sticky chat is attached to a document, the document can be sent and shared with others within seconds, who may then manipulate and edit the document, and the sticky chats.

  E-scape session services
  A set of services which allow users to easily locate and join on-going collaborative sessions. The services novelty lies in the ability to support the connection to any type of heterogeneous session through a framework of extensible and downloadable plug-in launchers that manage these connections. The services are written as a suite of Java servlets that present HTML interfaces and communicate through a combination of normal HTTP requests and more specific requests which are 'piggy-backed' on the protocol.

  Shared Universe Platform
  The platform implements a general model for sharing data and events between heterogeneous applications, with varying network and computational characteristics. The model exploits the notion of a distributed tuple space for communication, provided in the platform by the ëLimbo2' tuple space implementation. The model supports different models of collaborative session to be concurrently applied to the shared space.

  BSCW system
  The BSCW (Basic Support for Cooperative Work) system provided a desktop-like metaphor to allow users to upload, browse and download shared files on a remote BSCW server. In addition, the BSCW system provided other services such as message forums, calendars, group-based access control and workspaces. The server was written exclusively using Python CGI scripts and incorporated most aspects of the HTML and HTTP standards (Basic authentication, Mime-Multipart encoding, conditional GET etc.). Adhering to standards and using a web browser as the client enabled the BSCW system to be easily deployed and had over 10000 registered users when it won the European Software Innovation Prize in 1996.

  Ariadne system
  The system recorded a user's interaction with a variety of on-line library catalogues which where subsequently reconstructed and displayed using an X-windows interface and a set of web pages. The captured record of activity can be used to enable librarians and even the program itself to identify problems with the search strategies employed by the user.

  COLA platform
  The COLA (Cooperating Objects for Lightweight Activities) platform implemented a model of cooperation which focused on the mechanisms for sharing objects within cooperative activities rather than the policies which govern how those mechanisms are employed. The model consisted of four elements: activities, roles, events and shared objects. The COLA platform provided mechanisms and several Interface Description Languages (IDLs) to manipulate and describe these elements, and provided a novel 'object adaption' mechanism which supplied a level of indirection between object interfaces and object users.
