Motion

One of the best things about sleeping on a train is the gentle rocking motion that lulls you off to la-la land. Well, the Ensven 3 Modular Bed Rocker brings that same motion to people's beds, with a lot more oomph than its predecessors.

Wi-Fi security usually means keeping virtual intruders out, but a new system claims to use Wi-Fi networks to detect physical intruders. Gamgee’s Wi-Fi Home Alarm System can learn to recognize people who belong there and alert you to strangers.

Realistic and immersive as VR gaming may be, it produces feelings of motion sickness in many people. The C-Infinity platform is claimed to keep that from happening, by better engaging the user's body in their avatar's actions.

Using paired smartphones, motion-capture app OpenCap films video and then uses AI to analyse human movement, providing detailed data for use in rehabilitation, presurgery plans and disease diagnostics – and is 1% of the cost of traditional technology.

GPS-enabled tracking collars allow scientists to learn a lot about wild animals, but the devices do have one major drawback – limited battery life. A new tracker gets around that limitation, as it's continuously powered by the animal's movements.

Typically, motion capture systems are confined to one studio containing multiple cameras, and they require subjects to wear sensor-equipped body suits. A new setup, however, is based around a single chest-mounted camera.

Scientists at the University of Bath have come up with a simpler method of motion capture, developing a computer model that can digitize dogs without the need for a motion capture suit and a suite of surrounding cameras.

Researchers at Carnegie Mellon University have developed a computer vision system that identifies and tracks gym exercises.

​Currently, if you're trying to digitally track someone's movements, a depth-sensing camera such as the Microsoft Kinect is one of the best ways to go. Researchers are developing a potentially better system, however, which involves attaching cheap sensors to the person's clothing.

​​Many visions of our self-driving future entail car cabins designed for passengers to relax, read and enjoy on-screen entertainment, but what will this mean for the prevalence of motion sickness?

​Although gazing at computer models of processes that we're studying can certainly be helpful, there's often just no substitute for getting your hands on an actual physical object. Realizing that, an MIT team has developed a system that creates 3D-printed "motion sculptures" based on 2D videos.

If you kick a ball on the ground, it will roll away from you – that’s pretty basic science. But mathematicians have found that a quantum ball would roll toward your foot instead. When a force is applied to them, quantum particles can move in the opposite direction, in an effect known as “backflow.”
