People are prone to errors in many aspects of life, including when entering numbers. The effects of these errors can be disastrous, for example when an incorrect number is entered when programming a medical infusion pump or when entering financial information into a system. Designing better systems may help to prevent these errors however, in order to do this we need to understand far more about the types of errors being made, and their causes. Unfortunately, there are very few documented examples of number entry errors and thus many of the studies conducted so far rely upon modelled, not real world data. This paper reports a study that was designed to elicit number entry errors and the subsequent process of creating a taxonomy of errors from the information gathered.

In this paper we describe results from an exploratory study observing infusion pump use in practice. From 31 observations of pump programming we note 10 low-level disturbances, which we conceptualise in terms of unremarkable error.

We present the results of a group interview of choreographers aimed at understanding their conceptions of how movement can be used to in live performance

A usability evaluation has been conducted to gain in-depth understanding of the usefulness and usability of HandsOnVideo and the study yields positive results. In this paper, we describe the evaluation method, report the experimental results, discuss the findings and envision possible future improvements.

The present paper starts with a crucial discussion about the imbalance between technological and human concerns in the context of human-computer interaction, an imbalance that has arisen partly from the mechanistic aspect and its impact on interaction design

This paper describes a new way of understanding Social Presence in technologically mediated communication by relating it to a well-established psychological relationship construct: Closeness. We propose a model whereby an individual’s long-term feeling of Closeness to others is influenced by communication events that are invested with a sense of Social Presence, as a function of the background level of psychological Closeness.

We present here a proposed design framework for intimate communication devices. The intention is to highlight the decisions designers have to make when coming up with new communication systems and provide a more formalised system for considering the issues involved.

While much has been written about recent successful social networking sites, this paper takes a different approach and examines vfridge, a social networking application developed 10 years ago, well before the current explosion, which, despite a vision that now seems prescient, was unsuccessful.

This study contributes to the discussion on video telephony for inter-generational family communication. We present an evaluation of 11 alternative interaction options next to the standard options “accept” or “decline” for video telephony in 10 family scenarios with 20 grandchildren and 20 grandparents.

We present Social Comics, a casual video game that allows players to act in short comic strips that they create.
