Services are now consumed on a variety of devices, from very large “interactive wall displays” through to mobile hand-held devices and even smaller form factors. Our researchers are finding ways to manage this incredible diversity of service endpoints while containing costs and re-using service content.
Because of the increased significance of video in online content our researchers have invented ways of optimising video compression without loss of quality (“Region of Interest encoding”). Other researchers are pioneering multi-modal methods to extract meaningful metadata from video (for example, automatically recognising people, brands and organisations), including new entities never encountered before.
Our researchers are also addressing the broad issues associated with information access across the multiple devices that a person uses (e.g. smartphones, desktops and tablets), with a focus on shared devices, such as tabletops and large wall displays. These devices are often located in public spaces, creating a different set of information exchange challenges to those for personal, mobile devices.
Location-based services are another focal point for our researchers. According to the Australian Bureau of Statistics, people spend most of their time at home (70%) and at work (21%). With home and work locations in mind, our researchers are addressing the concept of hyperlocal services, i.e. those services that target very specific local geographical areas like neighbourhoods. They have for this purpose developed an experimental platform called Neighbourhood Networks to support hyperlocal services.
