The Video Collection

The lab often made videos to summarise progress in our projects. The collection goes back to 1989, and the quality varies considerably. Some were amateur videos, while others were recorded and edited by professionals.

Sentient Computing - MobiCom 2000

Sentient Computing - MobiCom 2000 (August 2000)

The Active Bats are now deployed throughout the building. We have used this to build a sentient computing system in which the environment is the interface: accurate, consistent and ubiquitous. For a shorter edited version of the MobiCom video

Sentient Computing

Sentient Computing (May 1999)

The integration of Active Bats and other sensors is made possible by using an object model of the environment. Together with an API for programming with spatial relationships, they enable a style of programming called sentient computing.

Cyberspice (September 1998)

This summer student project took a fun application of our low-power low-range radio project called pen and made a well-engineered demonstration from it.

DART Shoebox

DART Shoebox (September 1998)

The DART project builds systems which allow indexing and retrieval of multimedia from large archives. In this example application we applied DART technology to the problem of the storing and finding pictures in personal photographic collections. Speech annotations are attached to the photos. The speech is then automatically recognised so that photos can be searched for and retrieved using keywords. Image content can also be used to retrieve photos from the archive.

Ultrasonic Location Sensing

Ultrasonic Location Sensing (September 1998)

Small, wearable devices known as Active Bats and ceiling-mounted ultrasonic sensors are used to follow the time-varying 3D position of people and objects in a building.

Virtual Network Computing

Virtual Network Computing (1998)

VNC is a remote display system which allows you to view a computing 'desktop' environment not only on the machine where it is running, but from anywhere on the Internet and from a wide variety of machine architectures.

Network Computer Architectures

Network Computer Architectures (1996)

Network computers can present a simpler and more manageable interface to the user. The ATM network computer developed at our lab was a stateless device which combined a pen interface with a network-remoted windowing system. It was also a high-bandwidth networked multimedia display. In contrast a purely software development, the Virtual Network Computer, requires only a Web browser to interact with a windowing system running back at base.

Video Mail Retrieval

Video Mail Retrieval (August 1996)

The large collections of video mail which accumulated during the Pandora and later the Medusa projects suggested a difficult retrieval problem. The Video Mail Retrieval project showed that it was practical to use a speech recognition system in combination with traditional text-based techniques to achieve useful retrieval rates.

Modular Networked Multimedia

Modular Networked Multimedia (January 1996)

This video features new applications made possible by the Medusa approach of delivering large numbers of ATM multimedia streams to the desktop.

The MEDUSA Applications Environment

The MEDUSA Applications Environment (December 1994)

The Medusa project was based on a low-cost ATM network designed and prototyped at the lab. Many multimedia peripherals were developed which plug directly into the network. Modular software allowed rapid prototyping of new applications.

Teleporting (July 1994)

Teleporting allowed us to experiment with the idea of mobile user interfaces. Users can interact with their existing X applications at any X display.

Pandorino (1992)

The Pandora networked-multimedia hardware was repackaged as a smaller, more convenient design. 25 multimedia workstations were installed at sites around Cambridge and the videophone and videomail applications became part of the daily routine of a community of users.

The Active Badge System

The Active Badge System (April 1992)

The Active Badge was conceived, designed and prototyped at our lab between 1989 and 1992. It was the first of a series of research projects investigating mobility and location technology.

Active Badge on ``Beyond 2000''

Active Badge on ``Beyond 2000'' (March 1992)

The Active Badge was conceived, designed and prototyped at our lab between 1989 and 1992. It was the first of a series of research projects investigating mobility and location technology. This clip is taken from the Australian TV series "Beyond 2000".

Pandora (November 1990)

By 1990 multi-streamed multimedia running across the Cambridge Ring high speed network was in regular use at sites across Cambridge. The Pandora system provided videophone and videomail services seamlessly integrated with the X Windowing System.

Pandora Envisionment

Pandora Envisionment (July 1989)

This envisionment video was made while the Pandora project was still in development. It helped stimulate a debate on the possibilities of the new field of networked multimedia.
