Video: Augmented reality helps you up a climbing wall
Follow the light to scale that wall
Can a computer help you climb a rock face? Perttu H盲m盲l盲inen of Aalto University in Finland thinks so. He and Raine Kajastila have combined a projector and a Kinect depth camera to track rock climbers on a training wall, and provide feedback and suggestions in real-time. The system projects the route as a glowing line and tracks climbers as they follow it, suggesting moves as they go. There is also a game feature, where climbers must avoid a huge, projected chainsaw. The pair hope to install the system in a gym later this year.

Dell does deals in cryptocurrency

Companies accepting Bitcoin would have to hold enough of the currency to cover what they owe their customers at any time. They would also need to bolster their online defences.
