Leap Motion Controller. • USB Connection to Computing Device. SDK/Drivers. • Leap Motion Software. • Ground-breaking algorithms. • Third-party applications. The paper illustrates the use of Leap Motion controller for hand gesture recognition of Indian sign language signs using four similarity measures namely . Leap Motion technology tracks the movement of your hands and fingers, so you can reach into virtual and augmented reality to interact with new worlds.

All relevant data are within the paper and its Supporting Information files. Abstract Kinematic analysis of upper limb reaching provides insight into the central nervous system control of movements. Until recently, kinematic examination of motor control has been limited to studies conducted in traditional research laboratories because motion capture equipment used for data collection is not easily portable and expensive. A recently developed markerless system, the Leap Motion Controller LMC , is a portable and inexpensive tracking device that allows recording of 3D hand and finger position. The main goal of this study was to assess the concurrent reliability and validity of the LMC as compared to the Optotrak, a criterion-standard motion capture system, for measures of temporal accuracy and peak velocity during the performance of upper limb, visually-guided movements. In experiment 1, 14 participants executed aiming movements to visual targets presented on a computer monitor. Bland-Altman analysis was conducted to assess the validity and limits of agreement for measures of temporal accuracy movement time, duration of deceleration interval , peak velocity, and spatial accuracy endpoint accuracy. In addition, a one-sample t-test was used to test the hypothesis that the error difference between measures obtained from Optotrak and LMC is zero. Experiment 3 assessed the temporal coordination pattern during the performance of a sequence consisting of a reaching, grasping, and placement task in 15 participants. Results from the t-test showed that the error difference in temporal measures was significantly different from zero. The limits of agreement between the LMC and Optotrak for spatial accuracy measures ranged between 2—5 cm. Although the LMC system is a low-cost, highly portable system, which could facilitate collection of kinematic data outside of the traditional laboratory settings, the temporal and spatial errors may limit the use of the device in some settings.


You can even network more than one Leap device. Able to distinguish thumbs from fingers. The potential and many applications here are truly exciting but if the device really is going to be the revolution.

Leap Motion Seminar

We can control a computer in three dimensions with your natural hand and finger movements Leap Motion has, well, leapfrogged the state of the art in this young field, giving users the ability to control what's on their computers with hundredth of millimeter accuracy and introducing touch-free gestures like pinch-tozoom. The Leap Motion is a motion control interface designed for use with existing computers, and in demo videos the device calls to mind natural, sci-fi interfaces like the one found in the Tom Cruise blockbuster Minority Report.

Its motion control that doesnt look gimmicky or full of compromises and CEO and founder Buchwald told Beta Kit in an interview that in terms of underlying technology, Leap is heads and tails above most of whats out there.

Before diving into the more technical details of the device he created, Holz told us about the genesis of his idea to create a better way for humans to interact with their computational devices. The idea to do so came during his days acquiring a PhD in mathematics from UNC and while working in fluid mechanics.

You see, there's a problem with creating and manipulating 3D models using a mouse and keyboard -it's a needlessly complicated operation involving clicks and drop down menus.

Holz wanted a way to make "molding virtual clay as easy as molding clay in the real world. Unlike other motion-control options like Microsofts Kinect, Leaps focus is all about up-close-and-personal interactivity and delineating subtle, specific movements. That means people can interact with their computers in a much more natural way, instead of having to stand far back and be overly gestural and demonstrative in order to have tracking sensors pick up their movements.

In terms of being a practical tool people can use for daily productivity tasks, instead of, say, emulating jumping up and down on a river raft, that provides a very marked advantage What is leap motion?
