Computer spherograph, combined computer control device based on it

FIELD: computer functional devices.

SUBSTANCE: device is equipped with a lever with controlling and controlled arms, hanging on a support with the capability of moving controlled arm inside a spatial angle of a fixed spherical surface. Buttons and scroll wheel are located on controlling arm. Controlled arm, as well as the scanned interior spherical surface, is located inside the device.

EFFECT: increased efficiency and comfort of computer control, reduced surface occupied by device due to unification of device with keyboard case, increased device reliability due to the fact that scanned surface is located inside the device.

Known opto-mechanical and optical input device in the computer graphics information and management operating system /mouse/ /M. Kutuzov, A. Preobrazhensky Choice of computer. - M.: Peter, 2004, p.29-34/. The principle of them is based on registration of the movements of the remote sensor on the working surface and rendering it move on the screen through the cursor. Opto-mechanical mouse contains a ball rolling along the working surface, and two kinematically associated orthogonal roller transmitting the rotation of the ball on optical sensors that generate electrical impulses and enter them into the computer. As a result, the mouse movement is reflected on the monitor screen after the cursor. Optical mice have no moving parts. The principle of their action is that they send pulses of light on the working of the underlying surface and record the movement reflected through her signals.

The analogue can also be considered a device called a trackball. From the above mice it differs in that it is stationary, and the motion sensor is a ball, twisting fingers. The principle of the trackballs similar to mice and they also, as is YSI run as opto-mechanical, and optical.

A common disadvantage of the above devices is the dependence of the reliability of their work from a clean working surface and contamination, clogging of the ball with the trackball. Optical mouse, in particular, cannot operate on the reflecting mirror surface, for example on the Desk, covered in glass.

The technical result of the claimed invention is fixed localization of the underlying surface against which moved the motion sensor inside the device, the isolation of this surface from the external environment, the integration of computer spirograph and keyboard in one housing, including their interfaces.

This technical result is achieved by the fact that the claimed computer spirograph contains two shoulders lever with the managing and managed shoulders, hung on a support with the ability to erase managed shoulder solid angle with a fixed spherical surface against which is located on the shoulder motion sensor registers movement of the mechanical parts controlled shoulder and then entering data about these movements in the computer, and the buttons and scroll wheel are located on the control arm.

The claimed computer spirograph can be done in conjunction with the keyboard and separately. When time is entrusted the execution of computer spirograph requirements for the place of its installation is completely absent, you can work in almost any conditions, such as holding it in the hand or hanging on the wall. In this respect, the properties of computer spirograph close to the trackball, but the trackball outdoor ball has no protection from contamination and salination. This lack of computer spirograph no, because its surface scan is located inside the unit and isolated from the external environment.

Combining the keyboard with the computer spirograph allows you to create an aggregate device management, desktop computer, to substantially improve work with him. This is especially noticeable when working with complex engineering or artistic graphics. For many game programs also highly desirable is the combination of cursor control and operating system with the functionality of a keyboard.

The invention is illustrated by drawings on which is shown:

Figure 1. Computer spirograph /cut/.

Figure 2. Aggregate device management computer.

Computer spirograph /1/ contains the two shoulders with the control lever 1 and controlled 2 shoulders, hanging on the cross-piece 3, associated with the support 4. Managed the shoulder 2 is equipped with a sensor 5, the registering move it to the end part relative to the stationary spherical surface 6. On the panel is engaged in the shoulder 1 is a handle 7 with 8 keys and a scroll wheel 9. Bearing 4 mounted on the mobile platform 10, which has the ability to turn in a horizontal plane relative to the housing 1 keyboard and position the button 8 and the scroll wheel in your most comfortable working position.

Aggregate device management computer /2/ is a concatenation of the keyboard and spirograph in one body with a common interface. Possible location of computer spirograph on the calculator shown in figure 2. For simplicity, you can total the cable to provide paired with the motherboard connectors.

1. Computer spirograph representing an input device of the graphical information into a computer that contains a motion sensor, characterized in that it is equipped with a lever with the managing and managed shoulders, hung on a support for movement managed shoulder inside the solid angle fixed spherical surfaces, which is located on the managed shoulder motion sensor registers movement of the end part of controlled shoulder and then entering into the computer data on these movements, buttons and scroll wheel are located on the control arm, and as the driven shoulder and scanned the inner spherical surface located inside spirograph.

2. The combined device is the primary objective in the management computer, consisting of a keyboard mechanism for switching electrical circuits, representing a keyboard, wherein the provided computer spirograph according to claim 1, with the keyboard and computer spirograph combined into one unit with a common interface.
