Introducing MT-One
The MT-One is a new solution for better locomotion in VR. The unique thing about the System is that it is home user friendly. This thanks to the compact size of the system (approx.1.3x1m), low cost and almost no safety concerns. No other known solution meets similar specifications. As the inventor of the system, I invite you as a maker to join the community and build such a system yourself and develop the concept further.
About building such a system (disclaimer)
Although many problems could already be eliminated, the system presented here is still in an early development phase. During the development, much emphasis was placed on simplicity and reliability. The available documentation is far from being a construction manual, which means that makers or developers who want to build such a system must themselves have a relatively large amount of experience with hardware and software.
Disclaimer 2, I taught myself programming, so don't expect professional code. For a community project, all code will probably have to be rewritten and restructured. Nevertheless, the code works well and should be a good basis for further development.
How it works
The user is seated on a chair and connected to linear rails via several joints. The system allows a natural feeling walking motion that is transferred to the virtual environment. This makes the stationary walking movements feel like real walking movements with which move you forward. Two ayes of motion are computed, allowing for multidirectional movement. Unprecedented responsiveness and precision are achieved through the direct mechanical connection.

The license
The goal is to start a community project with this system. For this, all documents and materials are freely accessible to everyone. The concept is however under patent protection, this is irrelevant for non-commercial applications, which is the intention for the community project. With the patent protection I intend to generate resources for a widely available commercial system.
