An increasing number of notifications demanding the smartphone user's attention, often arrive at an inappropriate moment, or carry irrelevant content. In this paper we present a study of mobile user interruptibility with respect to notification content, its sender, and the context in which a notification is received. In a real-world study we collect around(More)
Notifications are extremely beneficial to users, but they often demand their attention at inappropriate moments. In this paper we present an in-situ study of mobile interruptibility focusing on the effect of cognitive and physical factors on the response time and the disruption perceived from a notification. Through a mixed method of automated smartphone(More)
It is becoming increasingly important that support is provided for users who are dealing with complex information spaces. The need is driven by the growing number of domains where there is a requirement for users to understand, navigate and manipulate large sets of computer based data; by the increasing size and complexity of this information and by the(More)
We report work on adding affect-detection to an existing e-drama programme, a text-based software system for (human) dramatic improvisation in simple virtual scenarios, for use primarily in learning contexts. The system allows a human director to monitor improvisations and make interventions, for instance in reaction to excessive, insufficient or(More)
We report progress on adding affect-detection to a program for virtual dramatic improvisation, monitored by a human director. To aid the director, we have partially implemented emotion detection. within users’ text input. The affect-detection module has been used to help develop an automated virtual actor. The work involves basic research into how affect is(More)
Remarkable advances in smartphone technology, especially in terms of passive sensing, have enabled researchers to passively monitor user behavior in real-time and at a granularity that was not possible just a few years ago. Recently, different approaches have been proposed to investigate the use of different sensing and phone interaction features, including(More)
Implementation intentions, 'if-then' plans where 'if's are contextual cues and 'then's are specific goal-related behaviours, hold much promise as an effective behaviour change technique to support habit formation. Nevertheless, they have been underused in digital behaviour change interventions. To address this gap, we outline a novel design of an(More)
There are a large number of computer based, and other, systems which are composed of large numbers of interacting components. Examples include large software systems, the world wide web and a wide range of information systems. Understanding and manipulating the structure and behaviour of these systems is extraordinarily difficult, even when the systems (eg.(More)
The work described here is concerned with enhancing the visualization of complex software systems (in particular object-oriented systems [4]). The major concern is to provide a powerful and concrete visual representation of such abstract systems, through which a user can move seamlessly from viewing the architectural structure to considering low level(More)
