How does it work?

Hardware

• IR camera and LEDs
• High-res, close-range
• USB

Software

• Daemon/Service
• Websocket server
• SDK

Ecosystem

• Developer program and community
• App store

How do we use it?

Let's install our devices

• https://www.leapmotion.com/setup
• (recommended) https://developer.leapmotion.com/
• If you already have it installed, try some of the apps

Config

• Open the Leap Motion control panel
• Make sure "Allow Web Apps" is enabled
• Must not have firewall blocking TCP over 127.0.0.1:6437, 6438, and 6439

What it does

• Views an "inverted pyramid" above the device
• Identifies hands, fingers, and pointing tools
• Reports location, motion, and gestures

Additional details

• Orientation is a right-handed Cartesian coordinate system
• Units are millimeters, mm/s, and radians

Data reporting

• Clients receive data at intervals
• Data is contained in a "frame"
• A frame contains info about detected objects
• Object info contains measurements
