An environment for studying the impact of spatialising sonified graphs on data comprehension

We describe AudioCave, an environment for exploring the impact of spatialising sonified graphs on a set of numerical data comprehension tasks. Its design builds on findings regarding the effectiveness of sonified graphs for numerical data overview and discovery by visually impaired and blind students. We demonstrate its use as a test bed for comparing the approach of accessing a single sonified numerical datum at a time to one where multiple sonified numerical data can be accessed concurrently. Results from this experiment show that concurrent access facilitates the tackling of our set multivariate data comprehension tasks. AudioCave also demonstrates how the spatialisation of the sonified graphs provides opportunities for sharing the representation. We present two experiments investigating users solving set data comprehension tasks collaboratively by sharing the data representation

Client’s championing characteristics that promote construction innovation

Purpose: clients or users of products, processes or services are being identified as potential sources of innovation in construction. There are concerns on the degree of innovation within the construction industry, despite having potential to be innovative. The role that can be played by the construction client to promote innovation in the industry is well documented. However, lack of knowledge on the desirable characteristics of the construction client was identified as one of the barriers for the construction client to be an effective innovation promoter. Accordingly, the paper evaluates the characteristics of the construction client that promotes innovation. Research Methodology: the multiple holistic case studies were used as the research strategy and semi-structured interviews were used as the principal data collection technique. Code-based content analysis and cognitive mapping were used to analyse the interviews. Data analysis was supported by two computer aided software namely NVivo and Decision explorer. Findings: clients can increase the efficiency of work carried out towards the construction process, stimulate team dynamics and team action through the championing characteristics which in turn can strengthen the innovation process that lead to the innovative product. Being a team player, promoting respect for people, and knowledge and information dissemination are identified as constituents of the championing characteristics of clients that promote innovation in construction projects. The personal skills of clients such as competence, value judgement, flexibility, and self motivation will energise the success of the championing characteristics. Originality/value: the client characteristics identified from the study widen the knowledge base of the client to successfully engage in construction innovation

Refining personal and social presence in virtual meetings

Virtual worlds show promise for conducting meetings and conferences without the need for physical travel. Current experience suggests the major limitation to the more widespread adoption and acceptance of virtual conferences is the failure of existing environments to provide a sense of immersion and engagement, or of ‘being there’. These limitations are largely related to the appearance and control of avatars, and to the absence of means to convey non-verbal cues of facial expression and body language. This paper reports on a study involving the use of a mass-market motion sensor (Kinect™) and the mapping of participant action in the real world to avatar behaviour in the virtual world. This is coupled with full-motion video representation of participant’s faces on their avatars to resolve both identity and facial expression issues. The outcomes of a small-group trial meeting based on this technology show a very positive reaction from participants, and the potential for further exploration of these concepts
