Microsoft recently showcased a new concept codenamed RoomAlive. By using projector depth camera units it allows users to interact with augmented content that seamlessly integrates with their physical surroundings. The system automatically adjusts to size, layout and colour of the room, allowing game developers to focus on content. The system will compensate for the users position and adjust the point of view to maintain the 3D positioning of elements.

 

Earlier this year Google announced Project Tango, an Android-based prototype 5″ phone and developer kit with advanced 3D sensors out of its Advanced Technology and Projects (ATAP) hardware skunkworks group.

Using sensors, the phone can build a visual map of rooms using 3D scanning. Google believes the combination of these sensors with advanced computer vision techniques will open up new avenues for indoor navigation and immersive gaming, among many other things.

In its announcement, Google raises the question, “What if you could capture the dimensions of your home simply by walking around with your phone before you went furniture shopping? What if directions to a new location didn’t stop at the street address? What if you never again found yourself lost in a new building?”

 

Many of us are used to Wi-Fi connectivity, whether it be at home, in restaurants or coffee shops, wireless access to the internet and our favourite social media apps is part of everyday culture.  Welcome (relatively) new comer, Li-Fi (light fidelity).  Both operate in the electromagnetic spectrum, but whereas Wi-Fi uses radio waves, Li-Fi uses visible light.

Light waves cannot penetrate walls, but reflected light off walls can still achieve transfer rates of 70Mbs.  More importantly, the visible light spectrum is 10,000 time larger than the radio frequency spectrum, Li-Fi is anticipated to be 10 times cheaper and environmentally more friendly than Wi-Fi.  The first smartphone to demonstrate this tech was shown at the Consumer Electronics Show Jan, 2014.
