PROJECTS

A selection of recent and ongoing research projects in which Attentive Displays was/is involved is given below:

Attentive multi-display walls (2007-)
Display banks or walls are used in CCTV control rooms, traffic control rooms, military and relief operation command and control centres, large TV and broadcast studios, shopping malls, etc. An attentive multi-display system comprises a multi-display wall where each display unit receives input from a separate video sensor and which can reconfigure itself dynamically by showing different videos on different displays based on the analysis of all incoming video streams and the behaviour and visual search patterns of the viewer(s).

Gaze-contingent displays (2006-)
Real-time monitoring of gaze position permits the introduction of display changes that are contingent on the spatial or temporal characteristics of eye movements. Such displays are called gaze-contingent displays (GCD). Many different GCD systems exist. Members of our team have (co-)designed and developed the first gaze-contingent display in the world using texture mapping and OpenGL and the first volumetric (3-D) gaze-contingent display. We are now looking at how to design useful and efficient GCDs for public displays.

Digital Maps for Public Displays (2008-)
Internet map services are now widely available around the world, but little research has been carried out to assess how easily or efficiently such services are used in the context of task-based visual processing. One ideal method of assessing viewer ability at using such online map services on personal and public displays is through examining how participants presented with a given task differ in terms of task performance and eye movements.

Eye Movements with Split Screen Displays (2008-)
In recent years all around us we see various new information displays appearing in public and personal spaces. We also witness the increased use of multiple displays in many different applications and user interfaces. In such systems multiple videos or films are shown either on multiple adjacent screens or a large display is split into several screens, thus creating a split-screen display. We are studying how such split-screens in films, advertisements and information displays affect eye movements and content perception and understanding.

Digital Spaces Living Lab (2008-)
The Digital Spaces Living Lab (DSLL) in Sofia, Bulgaria, was launched in 2008 to support industrial and academic partners working in the field of new digital media technologies. The DSLL provides a creative environment for research and innovation, as well as new forms of direct user involvement in the innovation process. It aims to establish new links between business enterprises, media partners, academia and citizens to ensure the successful collaboration between all these parties. The Digital Spaces Living Lab builds upon the highly successful Digital Spaces programme. Digital spaces are digital, virtual or computer-generated worlds but also the spaces we live in, where we use digital media, digital communication devices, digital gadgets, etc. Attentive Displays Ltd is the organisation 'hosting' DSLL and coordinating and managing it. Attentive Displays Ltd is also managing the technology incubator which is part of DSLL.

Scanpaths.org (2004-)
Attentive Displays is proud to be a supporter of Scanpaths.org (The Online Archive of Scanpath Data project)

ImageFusion.org (2003-)
Attentive Displays is proud to be a supporter of ImageFusion.org (The Online Resource for Research in Image Fusion project) 

AttentiveDisplays.org (2009-)
The central online resource for research in attentive displays. This public blog is created and maintained by Attentive Displays Ltd. (Coming live in January 2010).

Estimation of attention at a distance (2008-)
More information coming soon.
