The Mini 3D orientation sensor device has convex spherical body structure in a mechanical sensor coupled to logic to manage the reverse touchscreen component, alarm and other functions for the sensor. The spherical housing sensor is comprises a plurality of layers analogous to a touchscreen complete with conducting probes, an unconstrained surface compressing ball dynamic inside the spherical grid position structure that closes a electric circuit upon depressing the inside surface of the sphere housing. The sphere depressed coordinates are mapped to its 3D orientation upon output.
