Freespace Reference Kit
Hillcrest Labs has developed a Freespace Reference Kit to promote integration of Freespace technology into a wide array of devices.
For hardware developers, the Freespace Reference Kit simplifies prototyping and development of handheld devices that can benefit from motion-sensing data.
Software application developers can access Human Interface Device (HID) messages sent by the USB dongle to create Freespace-enabled applications without the need to learn motion-processing algorithms.
The HID message items include:
| Normal HID Message | Button, Wheel, Pointer [mickeys] |
| Motion Message (Body-Frame) | Supports tilt-based and crude games Supports differentiated motions Linear Acceleration [cm/s2], Angular Velocity [rad/s] |
| Position Message (User Frame) | Linear Offset [m] Angular Offset [quaternion] |
The Freespace Reference Kit includes:
| Handheld and dongle modules | These modules provide a quick and easy way to experience Freespace motion control technology without the need to install any software on the user's device. |
| Documentation | A User Guide and a Developer guide are included. The User Guide describes the setup and function of the kit. The Developer Guide describes the API, HID messages, and included code snippets. |
