This paper reports two studies of digital television users. The first study investigates the behaviour of non-impaired users to understand typical usage patterns and problem-solving, attempting three representative tasks using a digital television terrestrial receiver. Videos were analysed to identify problem incidents and attempts at recovery. Pat...

Over the last decade, the shift from analogue to digitaltechnology has brought about significant changes to thetelevision landscape. The subsequent emergence of mobile,IPTV and other carriers affords the opportunity to crea-tively reassess how people interact and engage within thisdiverging medium. Accessibility services to audio-visualcontent throu...

Preschool children have increased access to media via a number of platforms, including digital interactive television. However, the viewing and interaction needs of this user group have not been extensively researched. The project reported in this paper investigates preschoolers’ interactions with a simulated interactive television set-up. The stud...

This workshop will focus on setting the agenda for research, practice and policy in support of inclusive design for third generation computer-based products. The next generation of technology represents an unprecedented opportunity to improve the quality of life for groups of users who have previously faced exclusion, such as those with impairments...

Preschoolers' categorization differs from adults'; therefore it is beneficial to involve them in the design process to create appropriate information architecture for this age group. In this paper, we describe three card sorting activities conducted with a total of fifty six preschool children in five nurseries. We conclude that a closed card sorti...

The proliferation of audiovisual content available for young children brings with it the need for an appropriate Electronic Programme Guide (EPG) that meets needs and preferences of pre-schoolers. Two approaches to the design of such a service are discussed. Firstly, a range of existing guidelines on interactive television applications, personalize...

This paper describes an approach to the elicitation of accessibility requirements both to improve the design of existing technologies and develop new DTV utilities. The approach builds on previous work in which stalking-horse prototypes were used to explore possible design enhancements to interactive TV facilities. We describe a model of interactio...

Context Until relatively recently, the key technological device involved in computer-based and e-learning was assumed be a desktop PC, probably connected to the Internet. However, a plethora of new domestic and personal technologies now offers the educational technologist a wide range of platforms with which to engage the learner. Mobile devices an...

Interactive storytelling and gaming technologies have great edutainment potential for engaging visitors with museum exhibitions. This paper presents the development and testing of the Interactive Storytelling Exhibition Project devised originally within the Factual and Learning Interactive Television Department of the British Broadcasting Corporati...

Contemporary developments in digital and interactive television in the UK are reviewed to assess their accessibility implications for viewer/users with low vision. Of particular significance is the likelihood of divergence between sectors of the population receiving digital television in an enhanced form through new broadband distribution (thin cli...

Abstract This paper describes the development processes for a cross-platform ubiquitous language learning service via interactive television (iTV) and mobile phone. Adapting a learner-centred design methodology, a number of requirements were gathered from multiple sources that were subsequently used in TAMALLE (television and mobile phone assisted...

The UK National Health Service (NHS) is currently undergoing an intensive review into the way patient care is designed, delivered and recorded. One important element of this is the development of care pathways (clinical guidelines) that provide a reasoned plan of care for each patient journey, based on locally-agreed, evidence-based best practice....

In this paper we describe the design and development of a system that facilitates language learning from a combination of two devices, interactive television (iTV) and mobile phone. We present a number of requirements for technologies to support informal language learning based on theories of language learning, theories of formal and informal learn...

The potential of pattern languages as a vehicle for the dissemination of human-computer interaction design knowledge has been recognized within the CHI community (e.g. [4]), stemming from the ideas of the architect Christopher Alexander, for recording the designs of 'living buildings' [1-2]. Patterns record the invariant property that must exist in...

The majority of current text based search engines do not consider the semantic content of a document when they perform the process of indexing. As a result of this, retrieval is based on Boolean matches between the user's query and a set of loose terms that do not convey semantic meaning. In this paper we have used a partitioning type clustering al...

In this paper we present CODMAPS, a COst Distribution Method for Agent Planning Systems. The strategy is based on individual distribution of cost and competitive behaviour. Our model emulates how human agents work in expert groups. They all share a common objective but also have individual interests and try to steer the planning process towards the...

Interfaces to information systems, and the buildings in which such systems are embedded will typically be the result of the work of a large number of different disciplines, potentially ranging from ethnographers to architects. A common language and conceptual framework has the potential for greatly en- hancing the effectiveness and ease of cross-di...

In this paper we show how the problem of complexity in real-life planning problems can be tackled via decomposi- tion and merger of local solutions. In our system a task is partitioned among a set of independent planning agents. These are software entities capable of problem solving in a particular field and integrating them to form a composite glo...

Observational techniques are now well established as tools for evaluating the usability and acceptability of desktop systems such as interactive applications and web sites, whether in the user's own setting or in a usability lab. When interactive elements such as games, electronic programme guides and voting mechanisms began to be integrated into b...
