Approaches to Visualising the Spatial Position of ‘Sound-objects’

In this paper we present the rationale and design for two systems (developed by the Integra Lab research group at Birmingham Conservatoire) implementing a common approach to interactive visualisation of the spatial position of ‘sound-objects’. The first system forms part of the AHRC-funded project ‘Transforming Transformation: 3D Models for Interactive Sound Design’, which entails the development of a new interaction model for audio processing whereby sound can be manipulated through grasp as if it were an invisible 3D object. The second system concerns the spatial manipulation of ‘beatboxer’ vocal sound using handheld mobile devices through already-learned physical movement. In both cases a means to visualise the spatial position of multiple sound sources within a 3D ‘stereo image’ is central to the system design, so a common model for this task was therefore developed. This paper describes the ways in which sound and spatial information are implemented to meet the practical demands of these systems, whilst relating this to the wider context of extant, and potential future methods for spatial audio visualisation.</div

Selection-Based Mid-Air Text Entry on Large Displays

Abstract. Most text entry methods require users to have physical devices within reach. In many contexts of use, such as around large displays where users need to move freely, device-dependent methods are ill suited. We explore how selection-based text entry methods may be adapted for use in mid-air. Initially, we analyze the design space for text entry in mid-air, focusing on singlecharacter input with one hand. We propose three text entry methods: H4 Mid-Air (an adaptation of a game controller-based method by MacKenzie et al. [21]), MultiTap (a mid-air variant of a mobile phone text entry method), and Projected QWERTY (a mid-air variant of the QWERTY keyboard). After six sessions, participants reached an average of 13.2 words per minute (WPM) with the most successful method, Projected QWERTY. Users rated this method highest on satisfaction and it resulted in the least physical movement

Collaborative Immersive Analytics

International audienceMany of the problems being addressed by Immersive Analytics require groups of people to solve. This chapter introduces the concept of Collaborative Immersive Analytics (CIA) and reviews how immersive technologies can be combined with Visual Analytics to facilitate co-located and remote collaboration. We provide a definition of Collaborative Immersive Analytics and then an overview of the different types of possible collaboration. The chapter also discusses the various roles in collaborative systems, and how to support shared interaction with the data being presented. Finally, we summarize the opportunities for future research in this domain. The aim of the chapter is to provide enough of an introduction to CIA and key directions for future research, so that practitioners will be able to begin working in the field
