Players often talk about unpredictability being integral to their gaming experience. Uncertainty in games is a relatively new topic where player reports and existing literature suggest that it plays a key role in making the gaming experience richer. However, there is little to no empirical investigation into how players experience ...

Uncertainty is an important element of game play, which is widely believed to act as a precondition for player experience (PX). To investigate the concept and examine its relation to other PX concepts, we should be able to measure it. We present the design and preliminary results of the validation ...

Archaeologists are currently producing huge numbers of digitized photographs to record and preserve artefact finds. These images are used to identify and categorize artefacts and reason about connections between artefacts and perform outreach to the public. However, finding specific types of images within collections remains a major challenge. Often, the ...

Traditionally, the preservation of archaeological data has been limited by the cost of materials and the physical space required to store them, but for the last 20 years, increasing amounts of digital data have been generated and stored online. New techniques in digital photography and document scanning have dramatically increased ...

Archives of historical and cultural data, such as the UK's National Archives, receive huge volumes of enquiries from users. These have been seldom systematically studied, despite the obvious benefits to the organisations concerned and interaction designers. The literature looking at the spectrum of remote communications carried out by a modern ...

To better understand what researchers and practitioners consider to be the key components of the definition of web accessibility and to propose a unified definition of web accessibility, we conducted an analysis of 50 definitions of web accessibility. The definitions were drawn from a range of books, papers, standards, guidelines ...

Positive user experience (UX) is an important goal in product design. Positive long-term UX is believed to improve customer loyalty, therefore being vital for continuous commercial success. Most UX research investigates momentary or short-term UX although the relationship between the user and the product evolves over time. There is a ...

Given the proliferation of devices like infusion pumps in hospitals, number entry and in particular number entry error is an emerging important concern in HCI. There are clearly design features that could greatly improve accuracy in entering numbers but the context of the task could also play an important role. ...

This paper describes an empirical study of the problems encountered by 32 blind users on the Web. Task-based user evaluations were undertaken on 16 websites, yielding 1383 instances of user problems. The results showed that only 50.4% of the problems encountered by users were covered by Success Criteria in the ...

Expert evaluation methods, such as heuristic evaluation, are still popular in spite of numerous criticisms of their effectiveness. This paper investigates the usability problems found in the evaluation of six highly interactive websites by 30 users in a task-based evaluation and 14 experts using three different expert evaluation methods.

Citation Count: 0

Many security scenarios involve both network and cryptographic protocols and the interactions of different human participants in a real-world environment. Modelling these scenarios is complex, in part due to the imprecision and under-specification of the tasks and properties involved. We present work-in-progress on a domain-specific modelling approach for such scenarios; ...

Complex systems exhibit emergent behaviour. The explanations for this explicit emergent behaviour are often difficult to identify, and usually require understanding of significant parts of system structure and component behaviour to interpret. We present ongoing work on a set of techniques, based on Model-Driven Engineering principles and practices, for helping ...

Model-driven engineering (MDE) involves the construction and manipulation of many models of different kinds in an engineering process. In principle, models can be used in the product engineering lifecycle in an end-to-end manner for representing requirements, designs and implementations, and assisting in deployment and maintenance. The manipulations applied to models ...

The card sort technique has many uses in HCI research and practice. Card sorts have traditionally been conducted with physical cards but now programs are available for this task. It is unclear if results from an online version of this technique are as reliable as the "oncard" version. This paper ...

Mobile technologies such as multimedia guides (MMGs) are now an important part of the visitor experience in museums and other cultural spaces. We report the development of two scales to measuring visitors' museum experiences: the Museum Experience Scale (MES) and the Multimedia Guide Scale (MGS); these quantitative measures can helpfully ...
