Fingers

Capturing the complexities of the human hand is very tricky. Now engineers have developed a new wearable system that uses thermal sensors to accurately predict hand positions, with potential applications in VR, robotics and translating sign language.

Although there are already complex prototype interfaces that track all of the fingers on a computer-user's hand, let's be honest – it's mostly just the index finger that matters. That's where the experimental AuraRing system is designed to come in.

Because it doesn't show up in either blood tests or brain scans, Parkinson's disease can be frustratingly difficult to diagnose. A new device could help, however, by repeatedly bending the patient's finger. It may make diagnoses easier, and allow treatment to start earlier.

Currently, the most accurate method of checking for anemia is to draw a blood sample and conduct a count of a patient's red blood cells, which contain iron-rich hemoglobin. Soon, however, a smartphone app may be able to non-invasively do the same job.

What happens when you're immersed in a virtual world – such as a game – and you want to use your real-world fingers to control your virtual fingers in that world? Well, China's Dexta Robotics has created an exoskeleton for your hand, which can even provide the user with a sense of touch.

Researchers at Oregon State University (OSU) have designed an implant consisting of a simple pulley system that would more effectively transfer mechanical forces and allow more natural grasping function with less effort for those suffering reduced hand function.
-
ScienceMIT's "supernumerary robotic fingers" extend from either side of the user's dominant hand, and are attached to a device that's worn around the wrist. The idea behind them is that (among other things) they could allow users to perform tasks that usually require two hands, using only one.

The Titanium Utility Ring incorporates five tiny folding tools.

ScienceIn an effort to enable blind people to navigate their surroundings more safely and effectively, researchers have turned to rat whiskers.
-
Richard Van As and Ivan Owen have created a prototype prosthetic finger which could prove to be an inexpensive alternative to existing solutions.

The miniature Ubi-Camera uses the photographer's fingers as its viewfinder

The iDigiTip is a stylus that you wear on your finger or thumb.
