Precision typing on a smartwatch with finger gestures

The “Watchsense” prototype uses a small depth camera attached to the arm, mimicking a depth camera on a smartwatch. It could make it easy to type, or in a music program, volume could be increased by simply raising a finger. (credit: Srinath Sridhar et al.)
If you wear a smartwatch, you know how limiting it is to type it on or otherwise operate it. Now European researchers have developed an input method that uses a depth camera (similar to the Kinect game controller) to track fingertip touch and location on the back of the hand or in mid-air, allowing for precision control.

Germany breaks renewables record with coal and nuclear power responsible for only 15% of country’s total energy
Posted by Shailesh Prasad in categories: government, nuclear energy, sustainability
Germany has broken a new record for renewable energy, with low-carbon sources nearly obliterating coal and nuclear power last weekend.
At one point on the sunny and breezy Sunday, sustainable energy from wind, solar, biomass and hydro power provided a record 85 per cent of the country’s total energy.
Germany has been investing heavily in renewables, as part of the government’s Energiewende initiative to transition away from fossil fuels and nuclear power to a low carbon, environmentally sound, reliable, and affordable energy supply by 2050.

Researchers achieve direct counterfactual quantum communication
Posted by Shailesh Prasad in categories: particle physics, quantum physics
(Phys.org)—In the non-intuitive quantum domain, the phenomenon of counterfactuality is defined as the transfer of a quantum state from one site to another without any quantum or classical particle transmitted between them. Counterfactuality requires a quantum channel between sites, which means that there exists a tiny probability that a quantum particle will cross the channel—in that event, the run of the system is discarded and a new one begins. It works because of the wave-particle duality that is fundamental to particle physics: Particles can be described by wave function alone.
Well understood as a workable scheme by physicists, theoretical aspects of counterfactual communication have appeared in journals, but until recently, there have been no practical demonstrations of the phenomenon. Now, a collaborative of Chinese scientists has designed and experimentally tested a counterfactual communication system that successfully transferred a monochrome bitmap from one location to another using a nested version of the quantum Zeno effect. They have reported their results in the Proceedings of the National Academy of Sciences.
The quantum Zeno effect occurs when an unstable quantum system is subjected to a series of weak measurements. Unstable particles can never decay while they are being measured, and the system is effectively frozen with a very high probability. This is one of the implications of the well known but highly non-intuitive principle that looking at something changes it in the quantum realm.
