Wrist-camera tech tracks 3D hand pose, without seeing the fingers

When it comes to tracking the positions of a person’s moving hand, sensor-equipped gloves are often used. An experimental new system, however, utilizes a wrist-mounted camera … which doesn’t even “see” the user’s fingers.Continue ReadingCategory: Weara… Continue reading Wrist-camera tech tracks 3D hand pose, without seeing the fingers

Drone draws on the pufferfish to protect itself and others

Multicopter drones are becoming increasingly useful, but their exposed whirling propellers can get damaged in collisions, and inflict injuries on bystanders. A new prototype drone addresses that problem, by copying the pufferfish.Continue ReadingCatego… Continue reading Drone draws on the pufferfish to protect itself and others

Electric-wheeled Veelo is pulling for rollerbladers

Although there are electric rollerblades and skateboards, sometimes people just want a temporary boost while using their existing non-electric set of wheels. That’s why Veelo was invented.Continue ReadingCategory: Urban Transport, TransportTags: Kickst… Continue reading Electric-wheeled Veelo is pulling for rollerbladers

Smartphone-connected device measures the heat of chilis

Given that not everyone has the same tolerance for hot chilis, it would be good if there were a simple, portable means of objectively assessing exactly how hot they are. Well, scientists have developed just such a gadget – and it plugs into a smartphon… Continue reading Smartphone-connected device measures the heat of chilis

Wearable motion capture tech uses a single fisheye camera

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.Continue ReadingCategory: Scienc… Continue reading Wearable motion capture tech uses a single fisheye camera

Implantable material grows bone to heal holes in the skull

When a patient has a hole in their cranium, it typically has to be filled either with bone harvested from another part of their body, or with a solid piece of steel or plastic. There may soon be a better alternative, though, that stimulates the growth … Continue reading Implantable material grows bone to heal holes in the skull

Wheeled NASA rover splits in two to explore craters

Four-wheeled robotic rovers may be a good choice for the exploration of other planets, but they could conceivably get stuck at the bottom of deep craters. NASA’s DuAxel rover is designed with that in mind, as it splits in two for steep descents.Continu… Continue reading Wheeled NASA rover splits in two to explore craters
