Right now the device has 3 primary modes of operation, Balanced, Robust and Low Resource mode.

Balanced is the default mode of operation and cannot be toggled on or off. Robust and Low Resource are user-selectable through the Leap Motion Control Panel (under Tracking and Troubleshooting respectively). Robust Mode can also enable itself automatically if necessary.

Balanced Mode

This is the default mode for the device. It provides a balance of both tracking speed and accuracy. When plugged into a USB 2.0 port, it will provide data at a rate of approximately 120 frames-per-second (fps). When plugged into a USB 3.0 port, it will provide data at a rate of approximately 150 fps.

Robust Mode

This mode is automatically engaged in any non-optimal lighting scenario (as of software version 0.6.3). Right now this happens in a very conservative manner, and over time this mode should occur less and less often. Accuracy and range are slightly reduced, but tracking should remain usable in nearly any lighting condition. (We do not encourage outdoor environments, but they will often work.) Tracking speed will be approximately 100 fps in USB 2.0 mode, and 140 fps in USB 3.0 mode.
