WMG Research Seminar: Tuesday 29th November 2011, 12pm

Location: IMC Auditorium

Keynote: Prof. Alan Chalmers
 
Title:   Capturing and displaying real-world lighting
 
Abstract:
 
High Dynamic Range (HDR) video offers the possibility, for the first time, of capturing, storing, manipulating, and displaying dynamic real-world lighting. This gives a step change in viewing experience, for example the ability to clearly see the football when it is kicked from the shadow of the stadium into sunshine. An HDR video camera now exists which is capable of capturing 20 f-stops at full HD resolution (1920×1080) at 30 frames per second and commercial HDR displays are available. However, there are many significant challenges that still need to be overcome if HDR video is to be widely adopted and move from a niche research area into mainstream use. These include the need for high quality compression algorithms to cope with the enormous amount of data generated, the development of a common interface standard to facilitate widespread uptake, and even a definition of exactly what HDR is and what dynamic range might be considered “enough”. This talk discusses investigates these challenges and highlights some of the key endeavours being undertaken to ensure HDR is the future of imaging technology

Biography:

Alan Chalmers is Professor of Visualisation in the International Digital Laboratory, WMG, at the University of Warwick. He has published over 200 papers in journals and international conferences on realistic computer graphics, HDR imaging, parallel processing, multisensory perception and virtual archaeology, and successfully supervised 30 PhD students. He is Honorary President of Afrigraph and a former Vice President of ACM SIGGRAPH. In addition, he is Founder and Innovation Director of the spinout company, goHDR, which is developing software to facilitate the wide spread adoption of high dynamic range (HDR) imaging technology. His research is working towards achieving Real Virtuality: high-fidelity, multi-sensory virtual environments.

Opening talk:

Working in an Emergency Department (ED) is a demanding occupation, requiring high levels of concentration and long working hours. Stress and burn-out are commonly reported by medical staff. Poorly designed environments can be an unnecessary burden on staff collectively adding to stress levels over time. Besides from ambient temperature and lighting, specific environmental stressors affecting hospital staff have hardly been identified. Moreover, the provision of an environment which enables staff to cognitively and emotionally recover from their demanding work is important. Our research seeks to improve staff working conditions by identifying and addressing these issues through a participatory design approach.

Biography:

Sarah Payne is a Research Fellow in the Experiential Engineering group at WMG. She works on the Participation in Healthcare Environment Engineering programme, headed by Assistant Professor Rebecca Cain. As an Environmental Psychologist she is interested in people’s cognitive and emotional responses from their interaction with the environment, be that natural, urban or healthcare specific environments. The multi-sensorial experience of places, cars and urban artefacts are also considered aspects in her research
