Conference Paper
The ability to monitor and detect potentially dangerous behaviour in surrounding traffic is vital for the development of intelligent vehicles. However, data collection for these kinds of scenarios is difficult in real-life, and a driving simulator therefore becomes an important substitute. In this paper we present an approach to enhance driving sim...
Conference Paper
Driving is a cognitively demanding task, and many current navigation systems present confusing guidance instructions that add to the distraction. Human navigators, by contrast, schedule their advice to minimise distraction, and phrase instructions in terms of visible landmarks to avoid confusion. In this paper, we present the basis for a ‘natural n...

The process of driving a car involves a cognitive load that varies over time. Additional load comes from secondary factors not directly associated with the driving process, including navigation devices, entertainment systems and the car's own warnings. In this paper, we present a framework for intelligent scheduling of in-car notifications based on...
Patent
A method and system for character recognition are described. In one embodiment, it may use matched sequences rather than character shape to determine a computer legible result.
Conference Paper
Full-text available
Pico is a user authentication system that does not require remembering secrets. It is based on a personal handheld token that holds the user’s credentials and that is unlocked by a “personal aura” generated by digital accessories worn by the owner. The token, acting as prover, engages in a public-key-based authentication protocol with the verifier....
Patent
Full-text available
Information is captured from a rendered document with a handheld document data capture device. Electronic information associated with the rendered document is applied to determine the system's actions and/or behaviors in response to the data capture. In some embodiments, the electronic information is markup data or an action map associated with the...

We address the problem of locking and unlocking a device, such as a laptop, a phone or a security token, based on the absence or presence of the user. We detect user presence by sensing the proximity of a subset of their possessions, making the process automatic and effortless. As in previous work, a master key unlocks the device and a secret-shari...
Patent
Full-text available
A system for identifying an electronic counterpart for a rendered document is described. The system receives an indication of a text capture operation performed from a rendered document. The indication identifies a text sequence captured as part of the text capture operation, the identified text sequence comprising fewer than nine words. In respons...
Patent
Full-text available
A system for processing data captured from rendered documents is described.
Conference Paper
Full-text available
In previous work we presented Pico, an authentication system designed to be both more usable and more secure than passwords. One unsolved problem was that Pico, in its quest to explore the whole solution space without being bound by compatibility shackles, requires changes at both the prover and the verifier, which makes it hard to convince anyone...
Patent
Full-text available
A facility for storing a text capture data structure for a particular user is described. The data structure comprises a number of entries. Each entry corresponds to a text capture operation performed by the user from a rendered document. Each entry contains information specifying the text captured in the text capture operation.
Patent
A register interest system receives from a potential acquirer of assets an indication that the potential acquirer is interested in acquiring rights in a specific asset that is not currently on the market. The register interest system stores indications that the potential acquirers are interested in specific assets. When a notification criterion has...
Patent
A portable device having scanning, imaging or other data-capture capability is described. In some cases, the portable device can indicate to the user when enough information has been captured to uniquely identify a source document. In some cases, the portable device calculates timestamps and location-stamps indicating when and where a data capture...

Article
Some people say Internet years are like dog years, with one year on the Net being equivalent to seven years elsewhere. It is perhaps natural, then, that in 2001 one should start to mourn the demise of some of the earliest stars of the Web. It is now 10 years since the first Web Browser's became publicly available, although one would have been unlik...
Article
Full-text available
With thin-client virtual network computing technology, the support for synchronous collaboration offered by traditional CSCW tools has been extended to asynchronous participation in a shared workspace. Using frame buffer rectangles to relay pixel values, the system considered acquires and stores the ongoing computer session and offers all participa...
Article
Full-text available
In the future, the computer will be thought of more as an assistant than as a tool, and users will increasingly expect machines to make decisions on their behalf. As with a human assistant, a machine's ability to make informed choices will often depend on the extent of its knowledge of activities in the world around it. Equipping personal computers...
Article
Full-text available
The goal of `Computer Augmented Environments' is to bring computational power to everyday objects with which users are already familiar, so that the user interface to this computational power becomes almost invisible. Video is a very important tool in creating Augmented Environments and recent camera-manufacturing techniques make it an economically...

This paper identifies the current difficulties faced by the IT professionals working for collaborative enterprises and explains how we exploit and extend the so-called stateless client systems to support those individuals in cooperative work. Stateless client systems are the software tools that separate the display interface from the application lo...
Article
Full-text available
VNC is an ultra thin client system based on a simple display protocol that is platform independent. It achieves mobile computing without requiring the user to carry any hardware. VNC provides access to home computing environments from anywhere in the world, on whatever computing infrastructure happens to be available-including, for example, public...
