Description

Universal finger control

Technical field

Information technology, auxiliary input control devices for PCs, smart TVs, tablets, multimedia playback devices.

BACKGROUND OF THE INVENTION

Information and computer technology is usually controlled by additional input devices - keyboard and mouse. A mouse is an input device used to control the position of the cursor on the screen and enter input commands using the buttons. It is a graphical user interface. An example of this control is a tablet with a pen, a light pen, a steering wheel, a joystick and so on.

The disadvantage of almost all of these controls is that they require a solid support and are hand-operated. Depending on the type of controller technology, the substrate must meet certain conditions. shiny, slippery, colorful, etc.

According to the method of position sensing we distinguish: mechanical mouse - senses the position by means of a ball in the lower part, which rotates when the mouse is placed on a flat and firm surface. Optical mouse - position change is distinguished by means of light emitter and receiver, it must be placed on a flat and monochromatic base.

in

Other PC control alternatives - eg. pointing device, or joystick, located in the keyboard - are fixed in laptops. You cannot operate other devices with them.

Connection of the mouse to the computer is solved by cable via USB port, or wirelessly, via Bluetooth or radio transmission.

If you need to control the screen cursor, you need to move your hand from the keyboard to the mouse device on a solid pad. If the computer (portable) is outside the hardboard - e.g. knees, working with an external mouse is quite difficult.

Also other types of devices that can be controlled with the mouse - eg. TV with internet connection requires fixed placement of mouse pad. Such control is inconvenient, uncomfortable and may cause health problems on hand when used for a long time.

SUMMARY OF THE INVENTION

These disadvantages of the prior art IT device control are eliminated by the universal finger control (UFC).

SUMMARY OF THE INVENTION The present invention resides in a method of operating the cursor and buttons with one finger-thumb without the need for a pad. The dimensions of the universal finger control are adapted to the size of the second finger element to which the UFC slides. The relative position of the thumb and the universal finger control is ergonomic when working. The hand does not have to be held in one position as in a conventional mouse, thus avoiding the power and fatigue of the hand. Placing and operating the universal finger control on the finger does not restrict the hand to perform other tasks - typing on the keyboard, typing with a pen, holding a glass, etc.

The universal finger controller performs these functions. The motion function is provided by a joystick, which is located in the center of the universal finger control. It is a combined unit with a button. The joystick senses the force of compression using resistance strain gauges. The speed of movement is proportional to the force of pressure on the joystick. It is software adjustable. Controls the movement and position of the on-screen cursor. By pressing it and simultaneously deflecting it is possible e.g. scrolling through documents. The right and left buttons provide key functions. Their functions are configurable by the software currently in use.

All information from the joystick and buttons is handled by the processor located in the universal finger controller body. By connecting the universal finger controller to the computer without installing the control software, it functions like a classic computer mouse. If it is necessary to change the function of each control button, it is necessary to install the control software.

Data transfer from universal finger controller to controlled device (eg computer) is ensured eg. using a radio link at a frequency of 2.4 GHz, which provides a range of about 10-15 m. This solution requires a receiver (dongle) that connects to the USB port of the controlled device.

The power supply is located in the body of the universal finger controller, as a battery or as a rechargeable battery.

A third, additional function is a laser pointer serving e.g. to the presentation.

The universal finger controller is composed of two parts - the universal finger controller body and the finger - ring clip. At the bottom of the universal finger control is a sliding part - a handle that slips into the ring. The ring slides on the second link of the index finger for the easiest thumb control. The universal finger control is usable for both right and left hand. The adjustable ring size makes the universal finger control usable for both child and adult hands.

The universal finger control is functional without a ring. Thus it can be used universally - in the hand, on the knees, on the table.

BRIEF DESCRIPTION OF THE DRAWINGS

On p. 6 shows a finger clip. In FIG. 5 is a side view, FIG. 6 is a top view, FIG. 7 is a front view and FIG. 8 shows a handle in the space.

DETAILED DESCRIPTION OF THE INVENTION

It is to be understood that said embodiment of the invention is presented by way of example and not by way of limitation. Those skilled in the art will be able to design many variations to realize a patent - by changing the size, shape, addition or removal of various additional devices and elements. Such variants will also fall within the scope of the patent claims. It is not a problem for those skilled in the art to use the optimum technology, so it has not been solved in the present invention.

In FIG. 1 is an exemplary embodiment of a version of a universal finger actuator with a laser pointer. The universal finger controller body 3 incorporates a device that provides its functionality, connectivity and power supply to operate it. This technology is not claimed. In the middle of the upper body 3 is a built-in joystick 2, which controls the on-screen cursor. By pressing it and simultaneously deflecting it is possible e.g. scrolling. To the left and right of joystick 2 are the hotkeys 1. Their functions are defined by the software currently in use. On the front of the body 3 there is a button 5 for switching the laser 6 on and off (Fig. 2). On the underside of the body 3 there is a grip 4 which is inserted into the sliding part 8 of the ring 7 (in FIG. 7).

Industrial usability

The universal finger controller according to the invention serves as an additional input device for controlling computers, modern television sets, game consoles equipped with a USB port and at the same time as a laser pointer.

As it can be placed on the finger, the operation of these devices is very comfortable, there is no need for the hand to move from the keyboard to the computer mouse, requiring a solid base. In case it is not on the finger, the control can be placed on anything (eg knee, armrest ...) The handle on the bottom allows for easy carrying (on the pocket of clothing ...)

The versatile finger controller makes it easy and easy to operate the computer directly to the presenter, who can also use a laser pointer for presentation.

The universal finger control can be completed with multimedia buttons. The adjustable ring diameter makes the universal finger control universal for both child and adult hands. It can also be used on both the right and left hand.

The surface of the universal finger control can be of different materials, different colors and different patterns. The colors are more attractive to children, with inscriptions and patterns can serve as an object of advertising and in the design, where the ring of precious metal and body decorated, becomes a fashion accessory.

In a special waterproof design it can be used in damp and wet environments (frequent hand washing eg in health care, laboratories).
