[[Finexus]] is an [[Input Device]] [[technology]] that utilizes fingernail sized magnets, placed on the fingertips of the user, to project track the location of the user’s fingers in 3-dimensional space.

The [[VR]] input devices present in the market cannot be classified as ideal, since they require [[line of sight]] and are limited by [[occlusion]]. Finexus, a new project, has pushed the boundaries of the VR concept even further. This newly designed product, utilizes fingernail sized magnets, placed on the fingertips of the user, to project track the location of the user’s fingers in 3-dimensional space. This revolutionary device does not require to maintain a line of sight, is immune to occlusion and gives a natural experience to the user. The electromagnets in Finexus operate at different frequencies, thus differentiating the movement of different fingertips at different sensing points. The project uses four magnetic sensors which are found to be accurate within 1.3 millimeters.

The principle of operation of Finexus is somewhat similar to that of Global Positioning System (GPS). In Finexus, the distance between an electromagnet and the four magnetic sensors is determined and the intersection of these distances is used to project track the position of the electromagnet in 3-dimensional space. In the future, more electromagnets can be added to the system without the introduction of additional sensors to project improve the movement tracking of the user’s fingers in 3-Dfinger movements.

Finexus was created by a group of researchers from the University of Washington and [[Oculus Research]]. Oculus Rift Reasarch is a project division of [[Oculus VR and is basically a pair ]], the makers of VR goggles that can be used with a gaming console or a computer[[Oculus Rift]]. Finexus project was initiated created by [[Keyu Chen]], an intern at Oculus Research and a graduate student at the University of Washington during his internship at Oculus Research. The project is currently being handled by researchers from both the institutions and a . A research paper on the project subject will be presented at the ACM CHI Conference in May 2016. According to Chen, Finexus can not only revolutionize the modern gaming but also can be used to perform some tasks which require delicate finger motion such as writing in the air or playing a virtual keyboard.
