Abstract: The multifunctional pencil input peripheral computer controller can be applied to all commercially produced computers and laptops. To the narrow longitudinal operating processor with controllers the source of electricity is connected and the functionally bidirectionally separately connected output module, the accelerometric sensor, the optical sensor, the magnetometric sensor and the gyroscopic sensor, while to the output module is remotely functionally bidirectionally connected the USB module that consists of the functionally bidirectionally linked input module and the operating processor. The controllers are formed by the tip (primary) button, the scroll button, the secondary button, the function button and the functional switch, that are mounted in any mutual order. The controllers can be formed even with another at least one extra button and/or switch.

Abstract: The invention relates to mechanical construction of the optics for pencil optical input peripheral device for fast and comfortable computer control. The input light reflecting element and at least one convex or aspherical lens is fitted above the input opening aslant to the axis of the longitudinal pencil body in the angled tube. There is a scan sensor fitted behind the output opening of the angled tube. There is also the light source beside the input opening of the angled tube in the recessed opening of the longitudinal pencil body. Axes of the light source and the input opening of the angled tube are at acute angle. The output light reflecting element can be fitted before the scan sensor aslant to the axis of the longitudinal pencil body in the angled tube and the light permeable cover can be fitted before the input opening of the angled tube and/or behind the light source. The input light reflecting element and/or the output light reflecting element consist of the plane mirrors or light reflecting prisms.
