Android marketing madness at Mobile World Congress
It was hard to get away from Google's Android mobile OS at the Mobile World Congress in Barcelona this year - with the green robot looming large over this year's show.
If the posters or giant Android models didn't take delegates' fancy then there was even a giant Android slide for them to try out.

Virtual reality headset
This retro-futurist looking get-up is part of a Swiss research project into how virtual reality affects people's perceptions of themselves.
As part of the research project taking place at the École Polytechnique Fédérale de Lausanne (EPFL), test subjects, pictured in February this year, wear a virtual reality headset that immerses them in a variety of 3D environments where they interact with different avatars. Electrodes strapped to their head monitor their brain activity in an attempt to gauge the subject's reactions.

Microsoft Kinect R&D
Computer vision can allow for some pretty snazzy new interfaces and new uses for computers, and in February this year Microsoft showed some of the uses that research projects are finding for its Kinect gesture-based gaming peripheral.
This shot shows a research project called Mirage Blocks, which uses a Kinect-style camera and a controller-less user interface, coupled with a 3D projector, to render real objects digitally in 3D space. One possible use for the system would be to allow remote workers to collaborate on design of an object.
