As the device sits on a desk with the status LED facing towards you, the X and Y axes lie in the horizontal plane. The Ultrahaptics system employs a right-handed coordinate system. Modulation Amplitude: arbitrary unit varying from 0 to 1.The Ultrahaptics system uses the following units: The Leap Motion® camera module and Ultrahaptics arrays use different coordinate systems. Ultrahaptics array operates in metres, while the Leap Motion® camera module returns values in millimetres. This tutorial will explain in more detail the matrix algebra used to map between each and work through examples to show how you can define your own tracking/array mapping. The Ultrahaptics STRATOS Inspire is a fully integrated device and should not be disassembled. NOTE: Any modifications of camera position apply only to our development kits and not the Ultrahaptics STRATOS Inspire. The alignment object can either be initialised by reading the device information, set using one of the provided library options, or overridden to use your own customised tracking position, either via an XML configuration file or directly in the constructor. Our API provides the Ultrahaptics::Alignment class as the mechanism for mapping between each. Ultrahaptics SDK comes with example code, showing how to use the data provided by the tracking device and control the array. Our demo software will automatically detect the array type and configure the alignment necessary to map between the tracking camera and array. Changing the array and Leap Motion® camera module positionsĪll Ultrahaptics development kits contain a Leap Motion® camera module for tracking the position of the hand and is mounted in a cradle attached to the array.
