For example, the user can effortlessly move or rotate objects in 3D on a computer screen when his/her fingertip touches the screen. The fingertip movement on a surface functions as a computer mouse to manipulate the movement of the computer cursor on a screen. The device can be attached to a stylist, pencil, or similar tools, and also be easily detached or attached at any moment. It is perfectly adaptable for use with HMDs, such as GOOGLE GLASS, while exploring the landscape, driving a car, or lying supine with the need to interact with a computer application. ## Claims ### Claim 1 A computer input device to provide the computer system with three simultaneous inputs representing a start point of a movement, a three-dimensional direction of the movement, and a speed of the movement wherein the computer input device is comprised of;
